NAME:WRECK Vulnerabilities Impact Millions of Smart and Industrial Devices
by Peter Reutemann 14 Apr '21

14 Apr '21

'Catalin Cimpanu, reporting at Record: Security researchers have found a new set of vulnerabilities that impact hundreds of millions of servers, smart devices, and industrial equipment. Called NAME:WRECK, the vulnerabilities have been discovered by enterprise IoT security firm Forescout as part of its internal research program named Project Memoria -- which the company describes as "an initiative that aims at providing the cybersecurity community with the largest study on the security of TCP/IP stacks." Although never visible to end-users, TCP/IP stacks are libraries that vendors add to their firmware to support internet connectivity and other networking functions for their devices. These libraries are very small but, in most cases, underpin the most basic functions of a device, and any vulnerability here exposes users to remote attacks. The NAME:WRECK research is the fifth set of vulnerabilities impacting TCP/IP libraries that have been disclosed over the past three years, and the third set disclosed part of Project Memoria.' -- source: https://it.slashdot.org/story/21/04/13/1849248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

There's Another Facebook Phone Number Database Online
by Peter Reutemann 14 Apr '21

14 Apr '21

'An online tool lets customers pay to unmask the phone numbers of Facebook users that liked a specific Page, and the underlying dataset appears to be separate from the 500 million account database that made headlines last week, signifying another data breach or large scale scraping of Facebook users' data, Motherboard reports. From the report: Motherboard verified the tool, which comes in the form of a bot on the social network and messaging platform Telegram, outputs accurate phone numbers of Facebook users that aren't included in the dataset of 500 million users. The data also appears to be different to another Telegram bot outputting Facebook phone numbers that Motherboard first reported on in January. "Hello, can you tell me how you got my number?" one person included in the dataset asked Motherboard when reached for comment. "Omg, this is insane," they added. Another person returned Motherboard's call and, after confirming their name, said "If you have my number then yes it seems the data is accurate." A description for the bot reads "The bot give [sic] out the phone numbers of users who have liked the Facebook page." To use the bot, customers need to first identify the unique identification code of the Facebook Page they want to get phone numbers from, be that a band, restaurant, or any other sort of Page. This is possible with at least one free to use website. From there, customers enter that code into the bot, which provides a cost of the data in U.S. dollars and the option to proceed with the purchase, according to Motherboard's tests. A Page with tens of thousands of likes from Facebook users can cost a few hundred dollars, the bot shows. The data for Motherboard's own Page would return 134,803 results and cost $539, for example.' -- source: https://tech.slashdot.org/story/21/04/13/1953232 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Nvidia To Make CPUs, Going After Intel
by Peter Reutemann 13 Apr '21

13 Apr '21

'Nvidia said it's offering the company's first server microprocessors, extending a push into Intel's most lucrative market with a chip aimed at handling the most complicated computing work. Intel shares fell more than 2% on the news. From a report: The graphics chipmaker has designed a central processing unit, or CPU, based on technology from Arm, a company it's trying to acquire from Japan's SoftBank Group. The Swiss National Supercomputing Centre and U.S. Department of Energy's Los Alamos National Laboratory will be the first to use the chips in their computers, Nvidia said Monday at an online event. Nvidia has focused mainly on graphics processing units, or GPUs, which are used to power video games and data-heavy computing tasks in data centers. CPUs, by contrast, are a type of chip that's more of a generalist and can do basic tasks like running operating systems. Expanding into this product category opens up more revenue opportunities for Nvidia. Founder and Chief Executive Officer Jensen Huang has made Nvidia the most valuable U.S. chipmaker by delivering on his promise to give graphics chips a major role in the explosion in cloud computing. Data center revenue contributes about 40% of the company's sales, up from less than 7% just five years ago. Intel still has more than 90% of the market in server processors, which can sell for more than $10,000 each. The CPU, named Grace after the late pioneering computer scientist Grace Hopper, is designed to work closely with Nvidia graphics chips to better handle new computing problems that will come with a trillion parameters. Systems working with the new chip will be 10 times faster than those currently using a combination of Nvidia graphics chips and Intel CPUs. The new product will be available at the beginning of 2023, Nvidia said.' -- source: https://hardware.slashdot.org/story/21/04/12/1639237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The FSF Doubles Down On Restoring RMS After His Non-Apology Apology
by Peter Reutemann 13 Apr '21

13 Apr '21

'In late March, the Free Software Foundation (FSF) readmitted its founder Richard M. Stallman (RMS) to its board, catching everyone by surprise. Now, weeks later, RMS "offers a defensive non-apology apology for the words and actions that led to his resignation from the FSF," writes Steven J. Vaughan-Nichols via ZDNet. Slashdot reader destinyland shares an excerpt of his statement from the Free Software Foundation's official website: Looking back over his life starting as a teenager, Stallman writes: "I realized that I didn't understand the subtle cues that other people were responding to. Later in life, I discovered that some people had negative reactions to my behavior, which I did not even know about. Tending to be direct and honest with my thoughts, I sometimes made others uncomfortable or even offended them -- especially women. This was not a choice: I didn't understand the problem enough to know which choices there were." "Sometimes I lost my temper because I didn't have the social skills to avoid it," Stallman adds. "Some people could cope with this; others were hurt. I apologize to each of them. Please direct your criticism at me, not at the Free Software Foundation. Occasionally I learned something about relationships and social skills, so over the years I've found ways to get better at these situations. When people help me understand an aspect of what went wrong, and that shows me a way of treating people better, I teach myself to recognize when I should act that way. I keep making this effort, and over time, I improve. Some have described me as being 'tone-deaf,' and that is fair. With my difficulty in understanding social cues, that tends to happen." This is just an excerpt. But through eight short paragraphs, Stallman seems to want to offer up a larger context for his badly-received defense of Professor Minsky on an MIT mailing list. (And Stallman adds later that "I condemn racism and sexism, including their systemic forms, so when people say I don't, that hurts too...") "I've learned something from this about how to be kind to people who have been hurt," writes Stallman. "In the future, that will help me be kind to people in other situations, which is what I hope to do." "RMS did not, however, address the many other issues which caused people to regret his return to a position of leadership," writes Vaughan-Nichols. Soon after the RMS post appeared on the FSF's front page, the board spoke on why they'd brought him back. The unsigned document states: The voting members of the Free Software Foundation, which include the board of directors, voted to appoint Richard Stallman to a board seat after several months of thorough discussion and thoughtful deliberation. We decided to bring RMS back because we missed his wisdom. His historical, legal and technical acumen on free software is unrivaled. He has a deep sensitivity to the ways that technologies can contribute to both the enhancement and the diminution of basic human rights. His global network of connections is invaluable. He remains the most articulate philosopher and an unquestionably dedicated advocate of freedom in computing. RMS acknowledges that he has made mistakes. He has sincere regrets, especially at how anger toward him personally has negatively impacted the reputation and mission of FSF. While his personal style remains troubling for some, a majority of the board feel his behavior has moderated and believe that his thinking strengthens the work of the FSF in pursuit of its mission. We take full responsibility for how badly we handled the news of his election to a board seat. We had planned a flow of information that was not executed in a timely manner or delivered in the proper sequence.

Git.PHP.net Not Compromised in Supply Chain Attack, but User Database Leak Possible
by Peter Reutemann 12 Apr '21

12 Apr '21

'Inside.com's developer newsletter reports: The PHP team no longer believes the git.php.net server was compromised in a recent attack, which prompted PHP to move servers to GitHub and caused the team to temporarily put releases on hold until mid-April... In an update offering further insight into the root cause of the late March attack, the team says because it's possible the master.php.net user database was exposed, master.php.net has been moved to main.php.net. The team also reset php.net passwords, and you can visit https://main.php.net/forgot.php to set a new password. In addition, git.php.net and svn.php.net are both read-only now. Two malicious commits were pushed to the php-src repo from PHP founder Rasmus Lerdorf and PHP core developer Nikita Popov, Popov announced March 28. After an investigation, the PHP team reassured users these malicious commits never reached end-users. However, the team decided to move to GitHub after determining maintaining its own git infrastructure is "an unnecessary security risk." "In 2019, the PHP team temporarily shut down its Git server after discovering that an attacker had maliciously replaced the official PHP Extension and Application Repository with a malicious one," reports CPO magazine. But this newer supply chain attack "targeted any server that uses PHP ZLib compression when sending data. Most servers use this functionality on almost all content except images and archives that are already size optimized." The supply chain attack would have turned PHP into a remote web shell through which the attackers could execute any command without authentication. This is because the malicious attackers would have the same privileges as the web server running PHP. The backdoor is triggered at the start of a request by checking if the request contains the word "zerodium." If this condition was met, PHP executes the code in the "User-Agentt" request header. The header closely resembles the PHP "User-Agent" request for checking for browser properties. The rest of the request would thus be treated as a command that could be executed on a PHP server using the server's privileges. This would allow the hackers to run any arbitrary command without the need for further privileges... PHP powers 80% of all websites. Thus, a successful supply chain attack exploiting the language could prove catastrophic.' -- source: https://developers.slashdot.org/story/21/04/11/022247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Reactions to Arch Linux's New Guided Installer
by Peter Reutemann 12 Apr '21

12 Apr '21

'Long-time Slashdot reader xiando quotes LinuxReviews: The community distribution Arch Linux has up to now required you to manually install it by entering a whole lot of scary commands in a terminal. Arch version 2021.04.01 features a new guided installer [reached by] typing python -m archinstall guided into the console you get when you boot the Arch Linux installation ISO. It is not very novice-friendly, or user-friendly, but it gets the job done and it will work fine for those with some basic GNU/Linux knowledge. Tech Radar writes that previously Arch Linux had "a rather convoluted installation process, which has given rise to a stream of Arch-based distros that are easier to install," adding that the new installer "was reportedly promoted as an official installation mechanism back in January, and was actively worked upon leading to its inclusion in the installation medium." Users have been calling on Arch Linux for simplifying the installation process for a long time, to bring it in line with other Linux distros. However, the Arch philosophy has always been to put the users in charge of every aspect of their installation, which is the antithesis of automated installers. Phoronix calls the new installer "very quick and easy," although "granted not as user-friendly / polished as say the Debian Installer, Red Hat's Anaconda installer, even Ubuntu's Subiquity, and other TUI/GUI Linux installers out there." They also note that Archinstall "does allow automatically partitioning the drive with your choice of file-system options, automatically installing a desktop environment if desired, configuring the network interfaces, and all the other basics." The method is quick enough that I'll likely use archinstall for future Arch Linux benchmarks on Phoronix as it also then applies a sane set of defaults for users... Five minutes or less and off to the races, ready for Arch Linux." But Slashdot reader I75BJC still favors "scary commands in a terminal," leaving this comment on the original submission: If you can't type with the big adults, stay on your PlayStation. Even Apple, with its very good GUI has a command line. The command line commands are more flexible, more specific, more subtle than the pointy-clicky GUI.' -- source: https://linux.slashdot.org/story/21/04/10/1755241 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

APKPure App Contained Malicious Adware, Say Researchers
by Peter Reutemann 10 Apr '21

10 Apr '21

'Security researchers say APKPure, a widely popular app for installing older or discontinued Android apps from outside of Google's app store, contained malicious adware that flooded the victim's device with unwanted ads. From a report: Kaspersky Lab said that it alerted APKPure on Thursday that its most recent app version, 3.17.18, contained malicious code that siphoned off data from a victim's device without their knowledge, and pushed ads to the device's lock screen and in the background to generate fraudulent revenue for the adware operators. But the researchers said that the malicious code had the capacity to download other malware, potentially putting affected victims at further risk.' -- source: https://it.slashdot.org/story/21/04/09/1834230 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Critical Zoom Vulnerability Triggers Remote Code Execution Without User Input
by Peter Reutemann 10 Apr '21

10 Apr '21

'ZDNet: A zero-day vulnerability in Zoom which can be used to launch remote code execution (RCE) attacks has been disclosed by researchers. The researchers from Computest demonstrated a three-bug attack chain that caused an RCE on a target machine, and all without any form of user interaction. As Zoom has not yet had time to patch the critical security issue, the specific technical details of the vulnerability are being kept under wraps. However, an animation of the attack in action demonstrates how an attacker was able to open the calculator program of a machine running Zoom following its exploit. As noted by Malwarebytes, the attack works on both Windows and Mac versions of Zoom, but it has not -- yet -- been tested on iOS or Android. The browser version of the videoconferencing software is not impacted. Computest researchers Daan Keuper and Thijs Alkemade earned themselves $200,000 for this Zoom discovery, as it was part of the Pwn2Own contest. In a statement to Tom's Guide, Zoom thanked the Computest researchers and said the company was "working to mitigate this issue with respect to Zoom Chat." In-session Zoom Meetings and Zoom Video Webinars are not affected. "The attack must also originate from an accepted external contact or be a part of the target's same organizational account," Zoom added. "As a best practice, Zoom recommends that all users only accept contact requests from individuals they know and trust."' -- source: https://it.slashdot.org/story/21/04/09/209227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Wix and Their Dirty Tricks
by Peter Reutemann 09 Apr '21

09 Apr '21

'Matt Mullenweg, co-founder of the open-source blogging platform WordPress, writes: Wix, the website builder company you may remember from stealing WordPress code and lying about it, has now decided the best way to gain relevance is attacking the open source WordPress community in a bizarre set of ads. They can't even come up with original concepts for attack ads, and have tried to rip-off of Apple's Mac vs PC ads, but tastelessly personify the WordPress community as an absent, drunken father in a therapy session. I have a lot of empathy for whoever was forced to work on these ads, including the actors, it must have felt bad working on something that's like Encyclopedia Britannica attacking Wikipedia. WordPress is a global movement of hundreds of thousands of volunteers and community members, coming together to make the web a better place. The code, and everything you put into it, belongs to you, and its open source license ensures that you're in complete control, now and forever. WordPress is free, and also gives you freedom. So if we're comparing website builders to abusive relationships, Wix is one that locks you in the basement and doesn't let you leave. I'm surprised consumer protection agencies haven't gone after them. Wix is a for-profit company with a valuation that peaked at around 20 billion dollars, and whose business model is getting customers to pay more and more every year and making it difficult to leave or get a refund. (Don't take my word for it, look at their investor presentations.) They are so insecure that they are also the only website creator I'm aware of that doesn't allow you to export your content, so they're like a roach motel where you can check in but never check out. Once you buy into their proprietary stack you're locked in, which even their support documentation admits.' -- source: https://it.slashdot.org/story/21/04/08/2011222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
