Bing Contract Prohibits DuckDuckGo From Completely Blocking Microsoft Tracking
by Peter Reutemann 25 May '22

25 May '22

'DuckDuckGo isn't as private as you thought. "Due to a confidential search agreement, the DuckDuckGo browser does not block all Microsoft trackers," reports Review Geek. "What's worse, DuckDuckGo only acknowledged this 'privacy hole' after it was discovered by a security researcher." From the report: Security researcher @thezedwards found that the mobile DuckDuckGo browser does not block Microsoft trackers on third-party websites, such as the Facebook-owned Workplace.com. Gabriel Weinberg, the CEO of DuckDuckGo, is now running damage control on Twitter. He explains that Microsoft cannot see what you search in DuckDuckGo, and the DuckDuckGo browser blocks all Microsoft cookies. But if you visit a website that contains Microsoft's trackers, then your data is exposed to services like Bing and LinkedIn. This is the result of DuckDuckGo's "search syndication agreement" with Microsoft. In order to pull search information from Bing, the privacy experts at DuckDuckGo have to poke holes in their browser's security system. While DuckDuckGo has a solid privacy policy when it comes to Microsoft's ads, it hasn't explained how Microsoft uses data from third-party trackers. And that's quite alarming. Maybe this situation is overblown, or maybe Microsoft can build targeted ad profiles based on your web activity in DuckDuckGo -- we don't know because DuckDuckGo signed a confidentiality agreement. Gabriel Weinberg says that DuckDuckGo is "working tirelessly behind the scenes" to improve its deal with Microsoft. Additionally, he expects DuckDuckGo to "include more third-party Microsoft protection" in a future update.' -- source: https://yro.slashdot.org/story/22/05/24/218210 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Teaching Kiwi Kids To Refurbish Computers That They Get To Keep
by Lawrence D'Oliveiro 25 May '22

25 May '22

I saw an item about this on TVNZ news last night, but couldn’t find any mention on their website. But it turns out Newshub did a report on the project a week ago <https://www.newshub.co.nz/home/technology/2022/05/new-project-to-teach-kiwi…>. It involves primary-school-age children working with donated computers, learning how to dismantle them and fix them up. And then they have a working device that they get to take home: As part of West Tech, students as young as eight years old are taught how to diagnose issues, disassemble and then refurbish components in order to create an 'as-new' device. They are then gifted to the students, giving them refurbished tech products to help further their education. ... With just seven hours of learning time, students were able to learn to refurbish defunct devices ... I’m no hardware expert, so all I get to say is “wow”. One of the groups involved in this is youth charity Zeal <https://zeal.nz/>. They have centres in various places around the North Island (including Hamilton), though this particular project only seems to be at the West Auckland one. Looking for the tag “Zeal Digital” brings up several projects: <https://zeal.nz/tag/zeal-digital/>.

Microsoft Warns of 'Stealthy DDoS Malware' Targeting Linux Devices
by Peter Reutemann 24 May '22

24 May '22

'"In the last six months, we observed a 254% increase in activity from a Linux trojan called XorDdos," writes the Microsoft 365 Defender Research Team. It's a trojan combining denial-of-service functionality with XOR-based encryption for communication. Microsoft calls it part of "the trend of malware increasingly targeting Linux-based operating systems, which are commonly deployed on cloud infrastructures and Internet of Things devices." And ZDNet describes the trojan "one of the most active Linux-based malware families of 2021, according to Crowdstrike." XorDdos conducts automated password-guessing attacks across thousands of Linux servers to find matching admin credentials used on Secure Shell (SSH) servers... Once credentials are gained, the botnet uses root privileges to install itself on a Linux device and uses XOR-based encryption to communicate with the attacker's command and control infrastructure. While DDoS attacks are a serious threat to system availability and are growing in size each year, Microsoft is worried about other capabilities of these botnets. "We found that devices first infected with XorDdos were later infected with additional malware such as the Tsunami backdoor, which further deploys the XMRig coin miner," Microsoft notes... Microsoft didn't see XorDdos directly installing and distributing the Tsunami backdoor, but its researchers think XorDdos is used as a vector for follow-on malicious activities... XorDdoS can perform multiple DDoS attack techniques, including SYN flood attacks, DNS attacks, and ACK flood attacks. Microsoft's team warns that the trojan's evasion capabilities "include obfuscating the malware's activities, evading rule-based detection mechanisms and hash-based malicious file lookup, as well as using anti-forensic techniques to break process tree-based analysis. "We observed in recent campaigns that XorDdos hides malicious activities from analysis by overwriting sensitive files with a null byte. It also includes various persistence mechanisms to support different Linux distributions."' -- source: https://linux.slashdot.org/story/22/05/21/0445203 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Microsoft's Windows Subsystem For Android Just Got a Big Update
by Peter Reutemann 24 May '22

24 May '22

'Microsoft has updated the Windows Subsystem for Android (WSA) to Android 12.1 and shipped improvements to Android integration with Windows, networking, the camera in apps, the Settings app, and more. ZDNet reports: Current limitations aside, Microsoft is continuing to invest in bringing Android to Windows 11, as seen in its update to the WSA on Windows 11 (version 2204.40000.15) to Android 12.1, which is available to Insiders on the Dev Channel, according to a Microsoft blogpost. WSA launched with Android 11. Microsoft has improved networking on the Windows Subsystem for Android, so that Android apps can connect to devices on the same network as a Windows PC. Advanced networking allows users to set up smart home devices such as speakers and security cameras with a compatible Android app. This feature is available in Windows 11 preview builds 22621 and higher, with advanced networking on by default for new x64 Windows builds. Android-Windows integration has also been improved. Windows taskbar icons now show which Android apps are currently using hardware features like the mic and location in the system tray. The taskbar now also correctly appears or disappears when apps are running or stopped. Android notifications also show as Windows notifications and the Windows title of an Android app now reflects the Android activity title. Android apps won't restart afresh after exiting connected standby mode, but instead will recommence where the app was paused. Of the "many camera updates" in this release, Microsoft highlights that camera orientation is fixed to natural orientation, and that it's fixed incorrect camera previews, letterboxing (where the app window is wider than it is high, or horizontally longer), and a "squishing of the camera feed." Mouse and keyboard inputs in Windows Subsystem for Android have been improved. Microsoft also improved scroll-wheel support, fixed the onscreen keyboard focus, and ensured the Android soft keyboard displays correctly. The updated Windows Subsystem for Android Settings app gained redesigned UX and diagnostics data viewer. As of this update, telemetry collection is off by default. However, Microsoft is encouraging users to enable the setting, so it can collect data about Android app usage. "Other important updates include reduced flicker when apps are restored from a minimized state, the addition of VP8 and VP9 video hardware decoding, and the addition of Chromium WebView 100 to the Windows Subsystem for Android," adds ZDNet.' -- source: https://tech.slashdot.org/story/22/05/23/2014243 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Researchers find backdoor lurking in WordPress plugin used by schools

'Researchers said on Friday that they found a malicious backdoor in a WordPress plugin that gave attackers full control of websites that used the package, which is marketed to schools.

Why Gov.UK Stopped Using jQuery
by Peter Reutemann 22 May '22

22 May '22

'The head of the UK government's digital transformation unit recently announced a change to the nation's government services site gov.uk: they've "removed jQuery as a dependency for all frontend apps, meaning 32 KB of minified and compressed JavaScript was removed" for everything from selecting elements to attaching event listeners.... Nearly 84% of mobile pages used jQuery in 2021, points out a new essay at Gov.UK — before explaining why they decided not to: jQuery was an instrumental tool in a time when we really needed a way to script interactivity in a way that smoothed over the differing implementations of stuff like event handling, selecting elements, animating elements, and so on. The web is better because of jQuery — not just because it has such incredible utility, but because its ubiquity led to making what it provided part of the web platform itself. Nowadays, we can do just about anything jQuery can do in vanilla JavaScript... It really begs the question: Do we really need jQuery today? That's a question that GOV.UK has answered with a resounding "no".... This is a big deal when it comes to the user experience, because GOV.UK provides services and information online for The United Kingdom at scale. Not everyone is tapping away on their 2022 MacBook Pro on a rip-roarin' broadband connection. GOV.UK has to be accessible to everyone, and that means keepin' it lean.... dependencies matter when it comes to performance. Don't shortchange your users if the web platform can easily do the job a framework can. This level of commitment to the user experience from a institution that works at the scale GOV.UK does is commendable. I can only hope others follow in their footsteps.' -- source: https://developers.slashdot.org/story/22/05/21/0214233 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

HP Chooses Ubuntu-Based Pop!_OS Linux For Its Upcoming Dev One Laptop
by Peter Reutemann 22 May '22

22 May '22

'System76's CEO Carl Richell announced that HP has chosen the Ubuntu-based Pop!_OS operating system to run on its 14-inch developer-focused notebook called "Dev One." Brian Fagioli from BetaNews speculates that a HP acquisition of System76 "could be a possibility in the future -- if this new relationship pans out at least." He continues: HP could be testing the waters with the upcoming Dev One. Keep in mind, System76 does not even build its own laptops, so we could see the company leave the notebook business and focus on desktops only -- let HP handle the Pop!_OS laptops. "We've got you covered. Experience exceptional multi-core performance from the AMD Ryzen 7 PRO processor and multitask with ease. Compile code, run a build, and keep all your apps running with more speed from the 16GB memory. Plus, load and save files in a flash, thanks to 1TB fast PCIe NVMe M.2 storage. We've even added a Linux Super key so shortcuts are a click away. Simply put, HP Dev One is built to help you code better," explains HP. The company adds, "Pop!_OS is at your service. Create your ideal work experience with multiple tools to help you perform with peak efficiency. Use Stacking to organize and access multiple applications, browsers, and terminal windows. Move, resize, and arrange windows with ease or, let Pop!_OS keep you organized and efficient with Auto-tiling. And use Workspaces to reduce clutter by organizing windows across multiple desktops." Apparently, there will only be one configuration priced at $1,099. So far, no details about a release date have been announced other than "coming soon."' -- source: https://news.slashdot.org/story/22/05/21/0228258 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How a Rust Supply-Chain Attack Infected Cloud CI Pipelines with Go Malware
by Peter Reutemann 22 May '22

22 May '22

'Sentinel Labs provides malware/threat intelligence analysis for the enterprise cybersecurity platform SentinelOne. Thursday they reported on "a supply-chain attack against the Rust development community that we refer to as 'CrateDepression'." On May 10th, 2022, the Rust Security Response Working Group released an advisory announcing the discovery of a malicious crate hosted on the Rust dependency community repository. The malicious dependency checks for environment variables that suggest a singular interest in GitLab Continuous Integration (CI) pipelines. Infected CI pipelines are served a second-stage payload. We have identified these payloads as Go binaries built on the red-teaming framework, Mythic. Given the nature of the victims targeted, this attack would serve as an enabler for subsequent supply-chain attacks at a larger-scale relative to the development pipelines infected. We suspect that the campaign includes the impersonation of a known Rust developer to poison the well with source code that relies on the typosquatted malicious dependency and sets off the infection chain.... In an attempt to fool rust developers, the malicious crate typosquats against the well known rust_decimal package used for fractional financial calculations.... The malicious package was initially spotted by an avid observer and reported to the legitimate rust_decimal github account.... Both [Linux and macOs] variants serve as an all-purpose backdoor, rife with functionality for an attacker to hijack an infected host, persist, log keystrokes, inject further stages, screencapture, or simply remotely administer in a variety of ways.... Software supply-chain attacks have gone from a rare occurrence to a highly desirable approach for attackers to 'fish with dynamite' in an attempt to infect entire user populations at once. In the case of CrateDepression, the targeting interest in cloud software build environments suggests that the attackers could attempt to leverage these infections for larger scale supply-chain attacks.' -- source: https://developers.slashdot.org/story/22/05/21/0520207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Modular, DIY-friendly Framework Laptop gets updated with 12th-gen Intel CPUs
by Peter Reutemann 20 May '22

20 May '22

'We were fans of the Framework Laptop when we reviewed it last year. This was partly because its modular design prioritizes repairability and upgradeability when most other laptops don't. But we also liked it because you didn't need to make huge tradeoffs to get that repairability—the Framework Laptop is lightweight and has a high-quality screen, keyboard, and touchpad, helping it stay competitive with big-box thin-and-light laptops like Dell's XPS 13 and the Lenovo ThinkPad X1 Carbon. An upgradeable laptop is only worthwhile if you can actually upgrade it, though, and Framework is making that possible starting today: The company is introducing a new iteration of the Framework Laptop's motherboard that uses 12th-gen Intel CPUs. A brand-new 12th-gen Framework Laptop starts at $1,049 for a Core i5-equipped base model, or $819 for a build-it-yourself kit with no memory or storage. These products will be available for preorder starting today, and shipping will start in July. [...] While many of Framework's PCs will run Windows, the company boasts that the 12th-gen version of its laptop "continue[s] to focus on solid Linux support." Framework recommends Fedora 36 because it "works fantastically well out of the box" and fully supports the Framework Laptop's new CPUs, its Wi-Fi card, and its fingerprint reader. For now, though, you'll need to be careful about installing other Linux distributions—you need Linux kernel version 5.17.6 or newer to fully support Alder Lake's hybrid CPU architecture, and prominent, actively maintained distributions like Ubuntu 22.04 don't include that kernel version out of the box. This problem will disappear for most Linux distros within the next few months, but for now you may need to upgrade the kernel manually to get the best-possible Linux experience on the Framework Laptop. -- source: https://arstechnica.com/gadgets/2022/05/modular-diy-friendly-framework-lapt… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New Bluetooth hack can unlock your Tesla—and all kinds of other devices
by Peter Reutemann 19 May '22

19 May '22

'When you use your phone to unlock a Tesla, the device and the car use Bluetooth signals to measure their proximity to each other. Move close to the car with the phone in hand, and the door automatically unlocks. Move away, and it locks. This proximity authentication works on the assumption that the key stored on the phone can only be transmitted when the locked device is within Bluetooth range. Now, a researcher has devised a hack that allows him to unlock millions of Teslas—and countless other devices—even when the authenticating phone or key fob is hundreds of yards or miles away. The hack, which exploits weaknesses in the Bluetooth Low Energy standard adhered to by thousands of device makers, can be used to unlock doors, open and operate vehicles, and gain unauthorized access to a host of laptops and other security-sensitive devices.' -- source: https://arstechnica.com/information-technology/2022/05/new-bluetooth-hack-c… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Blocks File Manager Total Commander From Allowing Users To Sideload Apps
by Peter Reutemann 19 May '22

19 May '22

'Total Commander has been around since the 90s, eventually expanding into Android after the platform launched over a decade ago. The app has more than 10 million downloads on the Play Store, still supporting OS versions as far back as Android 2.2. With a new update, developer Christian Ghisler has removed the ability to install APK files on Android, blaming Google Play policies in the patch notes for the app. It's a shocking twist for the service and, seemingly, a bad omen of things to come for other mobile file managers. A forum post from Ghisler sheds some more light on what's going on here, as Google sent him a notice warning of his app's removal from the Play Store within a week if the app went unmodified. The company's automated response pointed the developer to the "Device and Network Abuse" policy.' -- source: https://tech.slashdot.org/story/22/05/18/1843221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Will Start Distributing a Security-Vetted Collection of Open-Source Software Libraries
by Peter Reutemann 18 May '22

'Google announced a new initiative Tuesday aimed at securing the open-source software supply chain by curating and distributing a security-vetted collection of open-source packages to Google Cloud customers. From a report: The new service, branded Assured Open Source Software, was introduced in a blog post from the company. In the post, Andy Chang, group product manager for security and privacy at Google Cloud, pointed to some of the challenges of securing open-source software and stressed Google's commitment to open source. "There has been an increasing awareness in the developer community, enterprises, and governments of software supply chain risks," Chang wrote, citing last year's major log4j vulnerability as an example. "Google continues to be one of the largest maintainers, contributors, and users of open source and is deeply involved in helping make the open source software ecosystem more secure." Per Google's announcement, the Assured Open Source Software service will extend the benefits of Google's own extensive software auditing experience to Cloud customers. All open-source packages made available through the service are also used internally by Google, the company said, and are regularly scanned and analyzed for vulnerabilities.' -- source: https://tech.slashdot.org/story/22/05/17/1726201 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Software Freedom Conservancy Wins Big Step Forward For Open-Source Rights
by Peter Reutemann 18 May '22

18 May '22

'ZDNet: The Software Freedom Conservancy (SFC), a non-profit organization that promotes open-source software and defends the free software General Public License (GPL), recently sued major TV vendor Vizio for abusing the GPL with its Linux-based SmartCast OS. Vizio replied that the SFC had no right to ask for the source code. On May 13, however, the SFC succeeded in federal court with its motion to have its lawsuit against Vizio remanded back to Superior Court in Orange County, CA. Doesn't sound like that big a deal? Think again. The important part of the decision by U.S. District Court Judge Josephine L. Staton stated that SFC's claim "that the [GPLv2] enforcement of 'an additional contractual promise separate and distinct from any rights provided by the copyright laws' amounts to an 'extra element,' and therefore, SFC's claims are not preempted." Karen M. Sandler, SFC's executive director, explained, "The ruling is a watershed moment in the history of copyleft licensing. This ruling shows that the GPL agreements function both as copyright licenses and as a contractual agreement." Sandler added that even in the Free and Open Source Software (FOSS) legal community people argue incorrectly that the GPL and other copyleft licenses only function as copyright licenses. This decision clearly states that the GPL also acts as a contract. Further, this decision makes it the first case to show individual consumers have rights to the source code as third-party beneficiaries of the GPL.' -- source: https://news.slashdot.org/story/22/05/17/2039236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

How Parliament Protest Supercharged NZ's Misinfodemic
by Lawrence D'Oliveiro 18 May '22

18 May '22

A report <https://www.nzherald.co.nz/nz/tectonic-shift-how-parliament-protest-superch…> on how online misinformation--and deliberate disinformation--has been spreading in NZ. A flood of recent Covid-19-related activity has exposed thousands more Kiwis to what the report's authors called "splintered realities", while also helping push people toward racist and violent ideologies. ... The websites they focused on ranged from mainstream platforms like Facebook, Twitter, Instagram and YouTube, to channels linked to the far-right, such as Telegram, Rumble, Odysee, Gab and Gettr. Each shift in New Zealand's Covid-19 response caused ripples across these sites. As our pediatric vaccine roll-out kicked off, for instance, one post bogusly claiming five children had collapsed at a vaccination centre swiftly went viral. In other words, a dramatic-sounding report, even though it was wrong, can spread faster than any attempts to correct it, simply because the correction seems much less interesting in comparison. You don’t have to assume that the ones spreading these reports are deliberately lying in order to create this effect: Hanlon’s Razor says “Never attribute to malice that which can be adequately explained by stupidity”. But the unprecedented surge in online traffic they observed around February's anti-mandate convoy to Wellington, and the 24-day occupation that followed, surprised even them. ... Posts on a single Facebook page, run by a known "misinformation super-spreader" they didn't name, drew some of the highest engagement of all public pages in the country over that period. The amount of traffic on Facebook misinformation pages even eclipsed that of pages operated by New Zealand mainstream media outlets combined – receiving 357,089 and 247,620 interactions respectively on March 2. There’s more in the news article, and also on the website of the Disinformation Project group which did the research <https://thedisinfoproject.org/>. I thought one of the names of the researchers was familiar: Dr Sanjana Hattotuwa. I’ve seen him on TV news a couple of times talking about this very thing.

Surprise: Microsoft Has a Second Internal-Use-Only Linux Distro
by Peter Reutemann 16 May '22

16 May '22

'ZDNet reports there's more than just the one Microsoft-created Linux distribution for internal use only called CBL (Common Base Linux) Mariner. "It turns out there's another Microsoft-developed Linux distribution that's also for internal use that's known as CBL-Delridge or CBL-D." I discovered the existence of CBL-D for the first time this week in a rather round-about way. I stumbled onto a February 2 blog post from Hayden Barnes. a Senior Engineering Manager at SuSE who led the Windows on Rancher engineering team, which traced his steps in discovering and building his own image of CBL-D. Barnes noted that Microsoft published CBL-Delridge in 2020, the same year that it also published CBL-Mariner. The main difference between the two: Delridge is a custom Debian derivative, while Mariner is a custom Linux From Scratch-style distribution. CBL-D powers Azure's Cloud Shell. The Azure Cloud Shell provides a set of cloud-management tools packaged in a container. In a note on the GitHub repo for the Cloud Shell, officials noted that "the primary difference between Debian and CBL-D is that Microsoft compiles all the packages included in the CBL-D repository internally. This helps guard against supply chain attacks...." CBL-Mariner and CBL-Delridge are just two of the Microsoft-developed Linux-related deliverables from the Linux Systems Group. Others include the Windows Subsystem for Linux version 2 (WSL2), which is part of Windows 10; an Azure-tuned Linux kernel which is designed for optimal performance as Hyper-V guests; and Integrity Policy Enforcement (IPE), a proposed Linux Security Module (LSM) from the Enterprise and Security team.' -- source: https://linux.slashdot.org/story/22/05/14/1934226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hackers Are Using SEO To Rank Malicious PDFs On Search Engines, Research Finds
by Peter Reutemann 15 May '22

15 May '22

'VentureBeat: Today, researchers at security service edge provider, Netskope, published the Netskope Cloud and Threat Report: Global Cloud and Malware Trends, which found that phishing downloads rose 450% over the past 12 months, and highlighted that attackers are using search engine optimization (SEO) to rank malicious PDF files on search engines. The report's findings show that phishing attempts are constantly evolving, and attackers aren't just targeting employees through their email inboxes; they're also using popular search engines like Google and Bing. The increase in phishing attacks and the growing popularity of SEO techniques among cybercriminals highlights the need for enterprises to provide their employees with security awareness training so they're prepared to spot threats and not at risk of handing over sensitive information. When it comes to defending against these SEO-driven attacks, [Ray Canzanese, director of Netskope's Threat Labs] highlights several methods that security teams can use to protect employees. One of the most effective is to use a solution that can decrypt and scan web traffic for malicious content. At the same time, security teams should encourage users to inspect all links they click on, and to exercise caution if the link takes them to an unfamiliar website. In the event an employee does click on a malicious PDF, they can expect to see a fake captcha at the top of the first page, followed by text on other pages. In these scenarios, users should close the file, delete it from the device and report it to the security team ASAP. Canzanese also notes that it's important for users to report malicious URLs that feature on popular search engines to help the provider unlist them from the site and prevent other users from falling victim to a scam.' -- source: https://it.slashdot.org/story/22/05/13/2155201 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Some top 100,000 websites collect everything you type—before you hit submit
by Peter Reutemann 15 May '22

15 May '22

'When you sign up for a newsletter, make a hotel reservation, or check out online, you probably take for granted that if you mistype your email address three times or change your mind and X out of the page, it doesn't matter. Nothing actually happens until you hit the Submit button, right? Well, maybe not. As with so many assumptions about the web, this isn't always the case, according to new research: A surprising number of websites are collecting some or all of your data as you type it into a digital form. Researchers from KU Leuven, Radboud University, and University of Lausanne crawled and analyzed the top 100,000 websites, looking at scenarios in which a user is visiting a site while in the European Union and visiting a site from the United States. They found that 1,844 websites gathered an EU user's email address without their consent, and a staggering 2,950 logged a US user's email in some form. Many of the sites seemingly do not intend to conduct the data-logging but incorporate third-party marketing and analytics services that cause the behavior. After specifically crawling sites for password leaks in May 2021, the researchers also found 52 websites in which third parties, including the Russian tech giant Yandex, were incidentally collecting password data before submission. The group disclosed their findings to these sites, and all 52 instances have since been resolved.' -- source: https://arstechnica.com/information-technology/2022/05/some-top-100000-webs… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

White House Joins OpenSSF, Linux Foundation In Securing Open-Source Software
by Peter Reutemann 15 May '22

15 May '22

'ZDNet: Securing the open-source software supply chain is a huge deal. Last year, the Biden administration issued an executive order to improve software supply chain security. This came after the Colonial Pipeline ransomware attack shut down gas and oil deliveries throughout the southeast and the SolarWinds software supply chain attack. Securing software became a top priority. In response, The Open Source Security Foundation (OpenSSF) and Linux Foundation rose to this security challenge. Now, they're calling for $150 million in funding over two years to fix ten major open-source security problems. The government will not be paying the freight for these changes. $30 million has already been pledged by Amazon, Ericsson, Google, Intel, Microsoft, and VMWare. More is already on the way. Amazon Web Services (AWS) has already pledged an additional $10 million. At the White House press conference, OpenSSF general manager Brian Behlendorf said, "I want to be clear: We're not here to fundraise from the government. We did not anticipate needing to go directly to the government to get funding for anyone to be successful." Here are the ten goals the open-source industry is committed to meeting: 1. Security Education: Deliver baseline secure software development education and certification to all. 2. Risk Assessment: Establish a public, vendor-neutral, objective-metrics-based risk assessment dashboard for the top 10,000 (or more) OSS components. 3. Digital Signatures: Accelerate the adoption of digital signatures on software releases. 4. Memory Safety: Eliminate root causes of many vulnerabilities through the replacement of non-memory-safe languages. 5. Incident Response: Establish the OpenSSF Open Source Security Incident Response Team, security experts who can step in to assist open source projects during critical times when responding to a vulnerability. 6. Better Scanning: Accelerate the discovery of new vulnerabilities by maintainers and experts through advanced security tools and expert guidance. 7. Code Audits: Conduct third-party code reviews (and any necessary remediation work) of up to 200 of the most-critical OSS components once per year. 8. Data Sharing: Coordinate industry-wide data sharing to improve the research that helps determine the most critical OSS components. 9. Software Bill of Materials (SBOMs): Everywhere Improve SBOM tooling and training to drive adoption. 10. Improved Supply Chains: Enhance the 10 most critical open-source software build systems, package managers, and distribution systems with better supply chain security tools and best practices.' -- source: https://it.slashdot.org/story/22/05/14/0336214 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hackers Are Exploiting WordPress Tools to Hawk Scams
by Peter Reutemann 15 May '22

15 May '22

'"If you've visited a website in recent days and been randomly redirected to the same pages with sketchy "resources" or unwanted ads, it's likely the site in question was 1) built with WordPress tools and 2) hacked," reports Gizmodo. Details come from this blog post by researchers at Sucuri (a security provider owned by GoDaddy): As outlined in our latest hacked website report, we've been tracking a long-lasting campaign responsible for injecting malicious scripts into compromised WordPress websites. This campaign leverages known vulnerabilities in WordPress themes and plugins and has impacted an enormous number of websites over the year — for example, according to PublicWWW, the April wave for this campaign was responsible for nearly 6,000 infected websites alone. Since these PublicWWW results only show detections for simple script injections, we can assume that the scope is significantly larger. We recently investigated a number of WordPress websites complaining about unwanted redirects. Interestingly enough, they were found to be related to a new wave of this massive campaign and were sending website visitors through a series of website redirects to serve them unwanted ads. The websites all shared a common issue — malicious JavaScript had been injected within their website's files and the database, including legitimate core WordPress files... This JavaScript was appended under the current script or under the head of the page where it was fired on every page load, redirecting site visitors to the attacker's destination.... Domains at the end of the redirect chain may be used to load advertisements, phishing pages, malware, or even more redirects.... At the time of writing, PublicWWW has reported 322 websites impacted by this new wave... Considering that this count doesn't include obfuscated malware or sites that have not yet been scanned by PublicWWW, the actual number of impacted websites is likely much higher. Our team has seen an influx in complaints for this specific wave of the massive campaign targeting WordPress sites beginning May 9th, 2022, which has impacted hundreds of websites already at the time of writing.... We expect the hackers will continue registering new domains for this ongoing campaign as soon as existing ones become blacklisted. "It's important to note that these hacks are related to themes and plugins built by thousands of third-party developers using the open source WordPress software, not WordPress.com, which offers hosting and tools to build websites," Gizmodo points out. But this also cite this warning from Sucuri malware analyst Krasimir Konov: "This page tricks unsuspecting users into subscribing to push notifications from the malicious site. If they click on the fake CAPTCHA, they'll be opted in to receive unwanted ads even when the site isn't open — and ads will look like they come from the operating system, not from a browser," Konov wrote.' -- source: https://it.slashdot.org/story/22/05/14/1838213 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

CentOS Successor Rocky Linux Gets $26M to Fund Push Into Enterprise Space
by Peter Reutemann 15 May '22

15 May '22

'"CIQ has landed $26 million in funding to support its plans to expand the use of Rocky Linux in the enterprise space," reports ZDNet. Last year, Red Hat decided to stop supporting CentOS 8 and shifted focus to CentOS Stream. CentOS had some huge enterprise users, among them Disney, GoDaddy, RackSpace, Toyota, and Verizon. In response, Greg Kurtzer, one of CentOS's founders, kicked off Rocky Linux in December 2020.... Kurtzer says Rocky Linux adoption has been "massive", with monthly downloads of OS images typically 250,000, reaching 750,000 in a bumper month. "Within two months we had 10,000 developer and contributors trying to be part of this project...." The project has gained the support of Greg Kroah-Hartman, the maintainer of the main-line stable Linux kernel, to meet community demands for Rocky Linux to run on a more modern, optimized kernel, Kurtzer said. Kroah-Hartman is leading Rocky Linux special interest group (SIG) for the kernel to create an optional enhanced kernel for Rocky Linux. "He's working closely with us to make sure the kernel we use is blessed by him. He's in the loop as bugs come up and help us manage that kernel in Rocky Linux," says Kurtzer. "Moreover, today's news follows shortly after CIQ inked a major deal with Google to help support companies looking to deploy Rocky Linux on Google's cloud infrastructure," reports VentureBeat. Kurtzer tells the site that Rocky Linux "has been a rocket ship in terms of uptake across the enterprise and cloud."' -- source: https://linux.slashdot.org/story/22/05/14/1913237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Zyxel silently patches command injection vulnerability with 9.8 severity rating
by Peter Reutemann 13 May '22

13 May '22

'Hardware manufacturer Zyxel quietly released an update fixing a critical vulnerability that gives hackers the ability to control tens of thousands of firewall devices remotely. The vulnerability, which allows remote command injection with no authentication required, carries a severity rating of 9.8 out of a possible 10. It’s easy to exploit by sending simple HTTP or HTTPS requests to affected devices. The requests allow hackers to send commands or open a web shell interface that enables hackers to maintain privileged access over time. The vulnerability affects a line of firewalls that offer a feature known as zero-touch provisioning. Zyxel markets the devices for use in small branch and corporate headquarter deployments. The devices perform VPN connectivity, SSL inspection, web filtering, intrusion protection, and email security and provide up to 5Gbps throughput through the firewall. The Shodan device search service shows more than 16,000 affected devices are exposed to the Internet.' -- source: https://arstechnica.com/information-technology/2022/05/zyxel-silently-patch… Should have used pfSense...

Google Cloud Launches AlloyDB, a New Fully-Managed PostgreSQL Database Service
by Peter Reutemann 13 May '22

13 May '22

'TechCrunch: Google today announced the launch of AlloyDB, a new fully-managed PostgreSQL-compatible database service that the company claims to be twice as fast for transactional workloads as AWS's comparable Aurora PostgreSQL (and four times faster than standard PostgreSQL for the same workloads and up to 100 times faster for analytical queries). [...] AlloyDB is the standard PostgreSQL database at its core, though the team did modify the kernel to allow it to use Google's infrastructure to its fullest, all while allowing the team to stay up to date with new versions as they launch. Andi Gutmans, who joined Google as its GM and VP of Engineering for its database products in 2020 after a long stint at AWS, told me that one of the reasons the company is launching this new product is that while Google has done well in helping enterprise customers move their MySQL and PostgreSQL servers to the cloud with the help of services like CloudSQL, the company didn't necessarily have the right offerings for those customers who wanted to move their legacy databases (Gutmans didn't explicitly say so, but I think you can safely insert 'Oracle' here) to an open-source service. "There are different reasons for that," he told me. "First, they are actually using more than one cloud provider, so they want to have the flexibility to run everywhere. There are a lot of unfriendly licensing gimmicks, traditionally. Customers really, really hate that and, I would say, whereas probably two to three years ago, customers were just complaining about it, what I notice now is customers are really willing to invest resources to just get off these legacy databases. They are sick of being strapped and locked in." Add to that Postgres' rise to becoming somewhat of a de facto standard for relational open-source databases (and MySQL's decline) and it becomes clear why Google decided that it wanted to be able to offer a dedicated high-performance PostgreSQL service. The report also says Google spent a lot of effort on making Postgres perform better for customers that want to use their relational database for analytics use cases. "The changes the team made to the Postgres kernel, for example, now allow it to scale the system linearly to over 64 virtual cores while on the analytical side, the team built a custom machine learning-based caching service to learn a customer's access patterns and then convert Postgres' row format into an in-memory columnar format that can be analyzed significantly faster."' -- source: https://developers.slashdot.org/story/22/05/12/0117241 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
