Huawei Considers Rivals To Google's Android After US Ban
by Peter Reutemann 21 May '19

21 May '19

'Huawei said it's working on its own operating system for its mobile handsets and will consider rivals to Google's Android, after the U.S. blacklisted the company, threatening its partnerships with chip, component and software suppliers. From a report: The Chinese telecom equipment giant said Tuesday it was in talks with the Alphabet about how to proceed after Google confirmed it would cut access to some of Huawei's operating system features for the company's new devices in response to the announcement. Should Google's system no longer be available, "then the alternative option will naturally come out -- either from Huawei or someone else," Abraham Liu, Huawei's representative to the European Union institutions, said at an event in Brussels on Tuesday. Liu said Huawei had been working on its own operating system but that he didn't have the details about when this would be ready. Huawei would do everything in its power to mitigate the impact of the U.S. decisions, Liu said' -- source: https://mobile.slashdot.org/story/19/05/21/1357240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 67 Arrives With New Performance and Privacy Features, Voice Search Widget on Android
by Peter Reutemann 21 May '19

21 May '19

'Mozilla today launched Firefox 67 for Windows, Mac, Linux, and Android. From a report: The 10th release since Mozilla's big Firefox Quantum launch in November 2017 doubles down on performance and privacy. Firefox 67 includes deprioritizing least commonly used features, suspending unused tabs, faster startup, blocking of cryptomining and fingerprinting, Private Browsing improvements, voice input in the Android search widget, and more. [...] Firefox 67 is better at performing tasks at the optimal time, resulting in faster "painting" of the page. Specifically, the browser deprioritizes least commonly used features and delays set Timeout to prioritize scripts for things you need. Mozilla says Instagram, Amazon, and Google searches now execute between 40% and 80% faster. Firefox also now scans for alternative style sheets after page load and doesn't load the auto-fill module unless there is a form to complete. Next, Firefox 67 detects if your computer's memory is running low (under 400MB) and suspends unused tabs. If you do click on a tab that you haven't used or looked at in a while, it will reload where you left off. Finally, Firefox 67 promises faster startup for users that customized their browser with an add-on.' -- source: https://news.slashdot.org/story/19/05/21/1636224 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

First Official Version of Tor Browser for Android Released on Play Store
by Peter Reutemann 21 May '19

21 May '19

'The Tor Project today made the first stable version of its privacy-focused browser available on the Google Play Store. From a report: This new mobile browser integrates the Tor protocol stack into a standalone browser and replaces Orfox as the main way to navigate the Tor network from an Android device. Tor Project developers have been working on this browser for eight months now, since September 2018, when they first released an alpha version for public testing. "We made it a priority to reach the rising number of users who only browse the web with a mobile device," said Isabela Bagueros, Executive Director of the Tor Project. "These users often face heavy surveillance and censorship online, so it is critical for us to reach them. We made sure there are no proxy bypasses, that first-party isolation is enabled to protect you from cross-site tracking, and that most of the fingerprinting defenses are working," the Tor team added.' -- source: https://yro.slashdot.org/story/19/05/21/1835256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel Performance Hit 5x Harder Than AMD After Spectre, Meltdown Patches
by Peter Reutemann 21 May '19

21 May '19

'Phoronix has conducted a series of tests to show just how much the Spectre and Meltdown patches have impacted the raw performance of Intel and AMD CPUs. While the patches have resulted in performance decreases across the board, ranging from virtually nothing to significant depending on the application, it appears that Intel received the short end of the stick as its CPUs have been hit five times harder than AMD, according to ExtremeTech. From the report: The collective impact of enabling all patches is not a positive for Intel. While the impacts vary tremendously from virtually nothing to significant on an application-by-application level, the collective whack is about 15-16 percent on all Intel CPUs without Hyper-Threading disabled. Disabling increases the overall performance impact to 20 percent (for the 7980XE), 24.8 percent (8700K) and 20.5 percent (6800K). The AMD CPUs are not tested with HT disabled, because disabling SMT isn't a required fix for the situation on AMD chips, but the cumulative impact of the decline is much smaller. AMD loses ~3 percent with all fixes enabled. The impact of these changes is enough to change the relative performance weighting between the tested solutions. With no fixes applied, across its entire test suite, the CPU performance ranking is (from fastest to slowest): 7980XE (288), 8700K (271), 2990WX (245), 2700X (219), 6800K. (200). With the full suite of mitigations enabled, the CPU performance ranking is (from fastest to slowest): 2990WX (238), 7980XE (231), 2700X (213), 8700K (204), 6800K (159). In closing, ExtremeTech writes: "AMD, in other words, now leads the aggregate performance metrics, moving from 3rd and 4th to 1st and 3rd. This isn't the same as winning every test, and since the degree to which each test responds to these changes varies, you can't claim that the 2990WX is now across-the-board faster than the 7980XE in the Phoronix benchmark suite. It isn't. But the cumulative impact of these patches could result in more tests where Intel and AMD switch rankings as a result of performance impacts that only hit one vendor."' -- source: https://hardware.slashdot.org/story/19/05/20/228218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

>20, 000 Linksys routers leak historic record of every device ever connected
by Peter Reutemann 21 May '19

21 May '19

'This post has been updated to add comments Linksys made online, which says company researchers couldn't reproduce the information disclosure exploit on routers that installed a patch released in 2014. Representatives of Belkin, the company that acquired Linksys in 2013, didn't respond to the request for comment that Ars sent on Monday. Ars saw the statement only after this article went live. More than 20,000 Linksys wireless routers are regularly leaking full historic records of every device that has ever connected to them, including devices' unique identifiers, names, and the operating systems they use. The data can be used by snoops or hackers in either targeted or opportunistic attacks. Independent researcher Troy Mursch said the leak is the result of a flaw in almost three dozen models of Linksys routers. It took about 25 minutes for the Binary Edge search engine of Internet-connected devices to find 21,401 vulnerable devices on Friday. A scan earlier in the week found 25,617. They were leaking a total of 756,565 unique MAC addresses. Exploiting the flaw requires only a few lines of code that harvest every MAC address, device name, and operating system that has ever connected to each of them. The flaw allows snoops or hackers to assemble disparate pieces of information that most people assume aren’t public. By combining a historical record of devices that have connected to a public IP addresses, marketers, abusive spouses, and investigators can track the movements of people they want to track. The disclosure can also be useful to hackers. The Shadowhammer group, for instance, recently infected as many as 1 million people after hacking the software update mechanism of computer maker ASUS. The hackers then used a list of about 600 MAC addresses of specific targets that, if infected, would receive advanced stages of the malware.' -- source: https://arstechnica.com/information-technology/2019/05/33-linksys-router-mo… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Distros Without Systemd (2019)

'It's 2019 -- who has switched to systemd, who hasn't and what can I use if I don't like systemd? Here's the answer in short. >From the blog post: If you are reading this post you're very much likely not a fan of systemd already. So we won't preach on why systemd is bad, but today we'll focus more on what are the alternatives out there. Our approach is obviously not for settling for less but for changing things for the better. We have started the world after systemd project some time ago and the search isn't over. So what are the non-systemd distros out there? The author makes a case for why you should consider the suggested distros, but here's the list: Devuan, Alpine Linux, Artixlinux, Void, Slackware, Gentoo, and GNU GUIX.' -- source: https://linux.slashdot.org/story/19/05/20/1916226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Opera Reborn 3: No modern browser is perfect, but this may be as close as it gets
by Peter Reutemann 20 May '19

20 May '19

'When Opera Software unveiled a new look and feel for its browser earlier this year, the company made a big deal of the impending changes. "We put Web content at center stage," the Opera team declared on its blog. And early previews of the design appeared to be quite pared down, allowing users to browse "unhindered by unnecessary distractions" as the Opera team put it. Well Opera recently released what the company refers to as Reborn 3, the latest version of its flagship desktop browser, and it's tempting to dismiss the name as little more than marketing hype. But given the relentless and utterly unspectacular updates that the Chromium project releases every six weeks, it can also be hard to denote actual big releases of browsers based on Chromium—hence the "Reborn" moniker. After spending some time with Reborn 3, however, the name seems accurate. For Opera, this is a significant update that goes far beyond what arrived with the move to Chromium 60. Opera Reborn 3—or Opera 60 if you want to stick with version numbers—transitions a slew of features that recently debuted in Opera's mobile browsers to the desktop. The big three in this release are support for blockchain-secured transactions, a crypto wallet to go with the mobile version, and a new overall look with light and dark themes available. So if you haven't checked out Opera lately, it's worth revisiting, especially for those older Opera fans still smarting about the switch from Opera's Presto rendering engine to Google's Blink rendering engine.' -- source: https://arstechnica.com/information-technology/2019/05/review-opera-once-le… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Is The Global Internet Disintegrating?
by Peter Reutemann 20 May '19

20 May '19

''The global internet is disintegrating," argues BBC Future, calling Russia "one of a growing number of countries that has had enough of the Western-built, Western-controlled internet backbone...aided as much by advances in technology as by growing global misgivings about whether the open internet was ever such a good idea to start with." "The new methods raise the possibility not only of countries pulling up their own drawbridges, but of alliances between like-minded countries building on these architectures to establish a parallel internet..." It's DNS that Russia has been setting its sights on... The plan -- which was met with skepticism from much of the engineering community, if not dismissed outright -- was to create a Russia-only copy of the DNS servers (the internet's address book, currently headquartered in California) so that citizens' traffic would be exclusively directed to Russian sites, or Russian versions of external sites. It would send Russian internet users to Yandex if they typed in Google, or the social network VK instead of Facebook. To lay the groundwork for this, Russia spent years enacting laws that force international companies to store all Russian citizens' data inside the country -- leading some companies such as LinkedIn to be blocked when they refused to comply... According to estimates from the International Institute for Strategic Studies in London, China is now engaged in some 80 telecommunications projects around the world -- from laying cables to building core networks in other countries, contributing to a significant and growing Chinese-owned global network... One possibility is a scenario where enough countries join Russia and China to develop a similar infrastructure to a point where they could sustain each other economically without doing business with the rest of the world, meaning they could shut themselves off the Western internet. Smaller countries might prefer an internet built around a non-Western standard, and an economic infrastructure built around China might be the "third way" that allows countries to participate in a semi-global economy while being able to control certain aspects of their populations' internet experience. Maria Farrell of the Open Rights Group (an internet freedom organisation) tells BBC Future that "Nations like Zimbabwe and Djibouti, and Uganda, they don't want to join an internet that's just a gateway for Google and Facebook" to colonise their digital spaces. And there's also fears about western espionage. "Along with every other expert interviewed for this article, Farrell reiterated how unwise it would be underestimate the ongoing reverberations of the Snowden revelations..."' -- source: https://tech.slashdot.org/story/19/05/19/1652253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Ends Android Collaboration With Huawei. No Gmail, Play Store For Future Huawei Phones
by Peter Reutemann 19 May '19

'Alphabet Inc's Google has suspended business with Huawei that requires the transfer of hardware and software products except those covered by open source licenses, a source close to the matter told Reuters on Sunday, in a blow to the Chinese technology company that the U.S. government has sought to blacklist around the world. Huawei Technologies Co Ltd will immediately lose access to updates to the Android operating system, and the next version of its smartphones outside of China will also lose access to popular applications and services including the Google Play Store and Gmail app... Huawei will continue to have access to the version of the Android operating system available through the open source license that is freely open to anyone who wishes to use it. But Google will stop providing any technical support and collaboration for Android and Google services to Huawei going forward, the source said.' -- source: https://mobile.slashdot.org/story/19/05/19/1829216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Pushes Kotlin Over Java for Android Development
by Peter Reutemann 18 May '19

18 May '19

'Google "officially declared Kotlin the go-to language for Android development last week at its Google I/O developer conference," reports Mike Melanson's "This Week in Programming" column, "and the company is backing that up with a couple of initiatives around making it easier (and free) to learn the language now used by a majority of Android developers." Google teamed up with Udacity to offer Developing Android Apps with Kotlin , a free, self-paced online course on how to build Android apps with Jetpack and Kotlin, meant for people who have programming experience and are comfortable with Kotlin basics. Google also announced "Kotlin/Everywhere, a series of community-driven events focussing on the potential of Kotlin on all platforms," which it is putting on in conjunction with JetBrains. Of course, this leaves the question that has been asked many times before -- why Kotlin? -- and IT consultant Kristen Carter offers a take on how Android app development became Kotlin-first. Carter offers some business angles, such as the 2010 lawsuit against Google by Oracle, which predates Kotlin by just a year, and she speculates may have been the impetus behind the language's development as "Google has always wanted to get away from the [Java] ecosystem." At the same time, Carter offers some language-specific reasoning too, such as the comparably succinct nature of Kotlin, the absence of Java's NullPointerExceptions, and the ease with which Java developers could transition to Kotlin. Carter ends her piece by posing the possibility that Oracle "knows the significance of Java in android app development" and could "ship Java with a few upgrades in its next version to take on Kotlin."' -- source: https://developers.slashdot.org/story/19/05/17/2355248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Long-time Slashdot reader solardiz has long bring an advocate for bringing security to open environments. Wednesday he contacted Slashdot to share this update about a piece of software he's authored called John the Ripper: John the Ripper is the oldest still evolving password cracker program (and Open Source project), first released in 1996. John the Ripper 1.9.0-jumbo-1, which has just been announced with a lengthy list of changes, is the first release to include FPGA support (in addition to CPU, GPU, and Xeon Phi). This is a long-awaited (or long-delayed) major release, encompassing 4.5 years of development and 6000+ commits by 80+ contributors. From the announcement: "Added FPGA support for 7 hash types for ZTEX 1.15y boards [...] we support: bcrypt, descrypt (including its bigcrypt extension), sha512crypt & Drupal7, sha256crypt, md5crypt (including its Apache apr1 and AIX smd5 variations) & phpass. As far as we're aware, several of these are implemented on FPGA for the very first time. For bcrypt, our ~119k c/s at cost 5 in ~27W greatly outperforms latest high-end GPUs per board, per dollar, and per Watt. [...] We also support multi-board clusters (tested [...] for up to 16 boards, thus 64 FPGAs, [...] on a Raspberry Pi 2 host)' -- source: https://it.slashdot.org/story/19/05/18/1841245 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Severe Linux Kernel Flaw Found In RDS
by Peter Reutemann 18 May '19

18 May '19

'Linux systems running kernels prior to 5.0.8 require patching after news emerged of a high-severity flaw that could be remotely exploited. According to the NIST advisory, CVE-2019-1181 is a race condition affecting the kernel's rds_tcp_kill_sock in net/rds/tcp.c "leading to a use-after-free, related to net namespace cleanup." The RDS bit refers to systems running the Reliable Datagram Sockets (RDS) for the TCP module, which means only systems that run applications using this are affected. The attention-grabbing part is that this opens unpatched systems to remote compromise and denial of service without the need for system privileges or user interaction. On the other hand, the attack complexity is described as 'high', and any such attack would need to be launched from the local network.' -- source: https://linux.slashdot.org/story/19/05/18/2122204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Wi-Fi Transmission Overhead?
by Lawrence D'Oliveiro 16 May '19

16 May '19

I’m currently copying a few gigabytes of files from my main workstation onto my laptop via wi-fi. Looking at dstat, on the workstation, it is reading about 4MB/s from the disk, but the network data transmission rate is a bit over twice that, more like 9MB/s. At the laptop end, it is receiving about 4MB/s over the network, which more closely matches the data being read from disk on the transmit side, but not the transmission rate. Has anybody else seen something similar?

SSH Password-Guessing Attacks

I suppose you know that if you put a machine on the Internet with an SSH server listening on port 22, you are going to get bombarded with password-guessing login attempts. Previously, I thought that moving the SSH server to a nonstandard port was sufficient to block these. But now I am seeing these attacks happening on my Rimu VPS anyway. Should I bother to change the port again?

Why Linux On Desktop 'Failed': A Discussion With Mark Shuttleworth

Google Is About To Have a Lot More Ads On Phones
by Peter Reutemann 14 May '19

14 May '19

'The Verge reports on the new ad types Google announced today that will start showing up throughout its mobile products, including some that interrupt the core Google search and discovery experiences. From the report: Google searches on mobile will soon include "gallery" ads that allow advertisers to display multiple images for users to swipe through. You'll also begin to see ads in Google's discover feed -- the feed of news stories that you find built into many Android home screens, inside the Google app, and on Google's mobile homepage -- though they'll only appear in select locations for now. The new ad formats are meant to make ads a lot more noticeable. In a blog post, Google ad chief Prabhakar Raghavan says that, in tests, gallery ads resulted in "up to 25 percent more interactions" than traditional search ads. Gallery ads will only be launching on mobile, not the desktop. Discover ads will appear in Google's mobile app, as well as on the discover feed on Android phones. Google tells us those ads won't appear in the discover feed that's built into the google.com mobile homepage. [...] The discover feed -- a personalized feed of recommended news stories that Google displays on mobile -- will also be getting ads for the first time. They'll appear just like any other story, with an image on top, a headline, and a subject field with more information. But they'll have a small badge that says "ad" to let users know it's sponsored. Those ads will extend to YouTube as well, where they'll slot in alongside recommended videos. Discover ads will also roll out later this year.

'Hard-To-Fix' Cisco Flaw Puts Work Email At Risk
by Peter Reutemann 14 May '19

14 May '19

'Security researchers have discovered serious vulnerabilities affecting dozens of Cisco devices. The flaws allow hackers to deceive the part of the product hardware that checks whether software updates come from legitimate sources. Experts believe this could put emails sent within an organization at risk as they may use compromised routers. Messages sent externally constitute less of a risk, however, as they tend to be encrypted. The California-based firm said it is working on "software fixes" for all affected hardware. "We've shown that we can quietly and persistently disable the Trust Anchor," Red Balloon chief executive Ang Cui, told Wired magazine. "That means we can make arbitrary changes to a Cisco router, and the Trust Anchor will still report that the device is trustworthy. Which is scary and bad, because this is in every important Cisco product. Everything." Security experts believe that the vulnerability could cause a major headache for Cisco, which has listed dozens of its products as vulnerable on its website. "We don't know how many devices could have been affected and it's unlikely Cisco can tell either," said Prof Alan Woodward, a computer security expert based at Surrey University. "It could cost Cisco a lot of money."' -- source: https://it.slashdot.org/story/19/05/14/1945212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Huawei is willing to sign no-spy agreements with governments, including Britain, the Chinese telecommunications company's chairman said on Tuesday as the United States pressures European countries to shun the firm over spying concerns. From a report: Washington has told allies not to use Huawei's technology to build new 5G telecommunications networks because of worries it could be a vehicle for Chinese spying, an accusation the firm has denied.' -- source: https://tech.slashdot.org/story/19/05/14/1531257 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Intel CPUs Released in Last 8 Years Impacted by New Zombieload Side-Channel Attack
by Peter Reutemann 14 May '19

14 May '19

'Academics have discovered a new class of vulnerabilities in Intel processors that can allow attackers to retrieve data being processed inside a CPU. From a report: The leading attack in this new vulnerability class is a security flaw named Zombieload, which is another side-channel attack in the same category as Meltdown, Spectre, and Foreshadow. Just like the first three, Zombieload is exploited by taking advantage of the speculative execution process, which is an optimization technique that Intel added to its CPUs to improve data processing speeds and performance. For more than a year, academics have been poking holes in various components of the speculative execution process, revealing ways to leak data from various CPU buffer zones and data processing operations. Meltdown, Spectre, and Foreshadow have shown how various CPU components leak data during the speculative execution process. Today, an international team of academics -- including some of the people involved in the original Meltdown and Spectre research -- along with security researchers from Bitdefender have disclosed a new attack impacting the speculative execution process. This one is what researchers have named a Microarchitectural Data Sampling (MDS) attack, and targets a CPU's microarchitectural data structures, such as the load, store, and line fill buffers, which the CPU uses for fast reads/writes of data being processed inside the CPU. [...] In a research paper published today, academics say that all Intel CPUs released since 2011 are most likely vulnerable. Processors for desktops, laptops, and (cloud) servers are all impacted, researchers said on a special website they've set up with information about the Zombieload flaws.' -- source: https://tech.slashdot.org/story/19/05/14/1721242 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Academics Improve SHA-1 Collision Attack, Make It Actually Dangerous
by Peter Reutemann 14 May '19

14 May '19

'"Attacks on the SHA-1 hashing algorithm just got a lot more dangerous last week with the discovery of the first-ever 'chosen-prefix collision attack,' a more practical version of the SHA-1 collision attack first carried out by Google two years ago," reports ZDNet. Google's original research allowed attackers to force duplicates for specific files, but this process was often at random. A new SHA-1 collision attack variation (a chosen-prefix attack) detailed last week allows attackers to choose what SHA-1-signed files or data streams they want to forge on demand, making SHA-1 an attack that is now practical in the real world, albeit at a price tag of $100,000 per collision.' -- source: https://it.slashdot.org/story/19/05/13/2255229 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
