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/

Nvidia Transitioning To Official, Open-Source Linux GPU Kernel Driver
by Peter Reutemann 12 May '22

12 May '22

'Nvidia is publishing their Linux GPU kernel modules as open-source and will be maintaining it moving forward. Phoronix's Michael Larabel reports: To much excitement and a sign of the times, the embargo has just expired on this super-exciting milestone that many of us have been hoping to see for many years. Over the past two decades NVIDIA has offered great Linux driver support with their proprietary driver stack, but with the success of AMD's open-source driver effort going on for more than a decade, many have been calling for NVIDIA to open up their drivers. Their user-space software is remaining closed-source but as of today they have formally opened up their Linux GPU kernel modules and will be maintaining it moving forward. [...] This isn't limited to just Tegra or so but spans not only their desktop graphics but is already production-ready for data center GPU usage.

Linux On Mars: NASA’s Ingenuity Helicopter Flies
by Lawrence D'Oliveiro 10 May '22

10 May '22

The first powered aircraft on Mars <https://www.theregister.com/2021/04/19/perseverance_computing_feature/> has proved its concept, taken flight for a few seconds, and made a controlled landing again. The control system is running Linux on a Qualcomm Snapdragon 801 chip, not because NASA considered it the best tool for the job, but because it was the easiest solution available. The hardware “is tuned for use on Earth, not Mars”, so it is only planned to make brief flights of no more than 90 seconds at a time, always landing back at the same spot, and it is not expected to endure beyond the initial 30 days of the Perseverance mission.

Hackers Are Now Hiding Malware In Windows Event Logs
by Peter Reutemann 10 May '22

10 May '22

'Security researchers have noticed a malicious campaign that used Windows event logs to store malware, a technique that has not been previously documented publicly for attacks in the wild. BleepingComputer reports: The method enabled the threat actor behind the attack to plant fileless malware in the file system in an attack filled with techniques and modules designed to keep the activity as stealthy as possible. [...] The dropper copies the legitimate OS error handling file [...] and then drops an encrypted binary resource to the 'wer.dll' (Windows Error Reporting) in the same location, for DLL search order hijacking to load malicious code. DLL hijacking is a hacking technique that exploits legitimate programs with insufficient checks to load into memory a malicious Dynamic Link Library (DLL) from an arbitrary path. [Denis Legezo, lead security researcher at Kaspersky] says that the dropper's purpose is to loader on the disk for the side-loading process and to look for particular records in the event logs (category 0x4142 - 'AB' in ASCII. If no such record is found, it writes 8KB chunks of encrypted shellcode, which are later combined to form the code for the next stager. "The dropped wer.dll is a loader and wouldn't do any harm without the shellcode hidden in Windows event logs," says Legezo. The new technique analyzed by Kaspersky is likely on its way to becoming more popular as Soumyadeep Basu, currently an intern for Mandiant's red team, has created and published on GitHub source code for injecting payloads into Windows event logs.

Hackers are actively exploiting BIG-IP vulnerability with a 9.8 severity rating
by Peter Reutemann 10 May '22

10 May '22

'Researchers are marveling at the scope and magnitude of a vulnerability that hackers are actively exploiting to take full control of network devices that run on some of the world's biggest and most sensitive networks. The vulnerability, which carries a 9.8 severity rating out of a possible 10, affects F5’s BIG-IP, a line of appliances that organizations use as load balancers, firewalls, and for inspection and encryption of data passing into and out of networks. There are more than 16,000 instances of the gear discoverable online, and F5 says it’s used by 48 of the Fortune 50. Given BIG-IP's proximity to network edges and their functions as devices that manage traffic for web servers, they often are in a position to see decrypted contents of HTTPS-protected traffic. Last week, F5 disclosed and patched a BIG-IP vulnerability that hackers can exploit to execute commands that run with root system privileges. The threat stems from a faulty authentication implementation of the iControl REST, a set of web-based programming interfaces for configuring and managing BIG-IP devices. “This issue allows attackers with access to the management interface to basically pretend to be an administrator due to a flaw in how the authentication is implemented,” Aaron Portnoy, the director of research and development at security firm Randori, said in a direct message. “Once you are an admin, you can interact with all the endpoints the application provides, including execute code.”' -- source: https://arstechnica.com/information-technology/2022/05/hackers-are-actively… 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/

GNOME Patent Troll Gets Stripped of Patent Rights
by Peter Reutemann 09 May '22

09 May '22

'An anonymous Slashdot reader writes: Remember that patent lawsuit filed against GNOME's Shotwell in 2019? An enterprising open source lawyer has challenged it within the patent office and gotten the whole thing canceled! OpenSource.org argues that decision by the U.S. patent office "may well give patent trolls cause to steer clear of open source projects — even more than the fierce resistance the community impressively funded and mounted in the GNOME case." Of the many methods developed over the past 20 years to eliminate patent threats against FOSS, none is as powerful as challenging the nefarious patents directly. That's what McCoy Smith, founder of OSI sponsor LexPan Law, did.... Smith pointed out in a re-examination request to the U.S. Patent & Trademark Office that the patent was not for any new invention. They agreed. As a result, all of these "claims" in the Rothschild '086 Patent — the part of a patent describing what the patent rights cover — have consequently been canceled. The Rothschild '086 patent can no longer be used against any victim, including open source projects. Of course, that's little comfort to the 20+ victims attacked after GNOME with the now-proven-worthless Rothschild '086 patent, or the 50+ companies targeted with related patents that haven't yet been re-examined.... Still, it's good to know there are open source champions of all sizes defending the development of open software.' -- source: https://yro.slashdot.org/story/22/05/08/0052226 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/

(Mostly) Open Source SteamOS Forked into Homegrown ISO For Other Machines
by Peter Reutemann 09 May '22

09 May '22

'"While Valve has yet to actually release a proper ISO for SteamOS 3 used on the Steam Deck, others have been taking it into their own hands to provide," reports GamingOnLinux, "like with the new HoloISO. "This is possible, since 99% of what SteamOS uses is open source (not the Steam client though)..." So people can easily hack away at it to do whatever they want. [HoloISO] is not exactly the same as SteamOS 3 but it's probably the closest I've seen yet, with the main packages coming direct from Valve with "zero possible edits" the developer says. It's described as a "first beta release." Neowin supplies some context: Back in early March, Valve released the Steam Deck recovery image for Deck users who need to get back to a factory state. When it was released, many of us over at the Steam OS subreddit did the first thing any reasonable enthusiast would do and tried installing it on a standard PC. The results of this approach were mixed, and only partial successes were achieved. Then HoloISO happened.... The first release, called 'Ground Zero', was released today and allows users to install Steam OS on any machine. But there are some things you need to know before installing this for yourself.... There's a bunch of caveats, but the article still concludes that "If you're team red and you want to give this a shot, head over to the project's Github page to read more and download."' -- source: https://games.slashdot.org/story/22/05/08/0844220 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/
