Mozilla Patches Firefox, Thunderbird Against Zero-Day Exploited in Attacks
by Peter Reutemann 14 Sep '23

14 Sep '23

'Mozilla has released emergency security updates to fix a critical zero-day vulnerability exploited in the wild, impacting its Firefox web browser and Thunderbird email client. From a report: Tracked as CVE-2023-4863, the security flaw is caused by a heap buffer overflow in the WebP code library (libwebp), whose impact spans from crashes to arbitrary code execution. "Opening a malicious WebP image could lead to a heap buffer overflow in the content process. We are aware of this issue being exploited in other products in the wild," Mozilla said in an advisory published on Tuesday. Mozilla addressed the exploited zero-day in Firefox 117.0.1, Firefox ESR 115.2.1, Firefox ESR 102.15.1, Thunderbird 102.15.1, and Thunderbird 115.2.2. Even though specific details regarding the WebP flaw's exploitation in attacks remain undisclosed, this critical vulnerability is being abused in real-world scenarios.' -- source: https://tech.slashdot.org/story/23/09/13/1328236 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Password-stealing Linux malware served for 3 years and no one noticed
by Peter Reutemann 13 Sep '23

13 Sep '23

'A download site surreptitiously served Linux users malware that stole passwords and other sensitive information for more than three years until it finally went quiet, researchers said on Tuesday. The site, freedownloadmanager[.]org, offered a benign version of a Linux offering known as the Free Download Manager. Starting in 2020, the same domain at times redirected users to the domain deb.fdmpkg[.]org, which served a malicious version of the app. The version available on the malicious domain contained a script that downloaded two executable files to the /var/tmp/crond and /var/tmp/bs file paths. The script then used the cron job scheduler to cause the file at /var/tmp/crond to launch every 10 minutes. With that, devices that had installed the booby-trapped version of Free Download Manager were permanently backdoored. After accessing an IP address for the malicious domain, the backdoor launched a reverse shell that allowed the attackers to remotely control the infected device. Researchers from Kaspersky, the security firm that discovered the malware, then ran the backdoor on a lab device to observe how it behaved. “This stealer collects data such as system information, browsing history, saved passwords, cryptocurrency wallet files, as well as credentials for cloud services (AWS, Google Cloud, Oracle Cloud Infrastructure, Azure),” the researchers wrote in a report on Tuesday. “After collecting information from the infected machine, the stealer downloads an uploader binary from the C2 server, saving it to /var/tmp/atd. It then uses this binary to upload stealer execution results to the attackers’ infrastructure.”' -- source: https://arstechnica.com/security/2023/09/password-stealing-linux-malware-se… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox Multi-Account Containers
by Peter Reutemann 11 Sep '23

11 Sep '23

Hi everyone Just came across this Firefox plugin: The Firefox Multi-Account Containers extension lets you carve out a separate box for each of your online lives – no more opening a different browser just to check your work email! Under the hood, it separates website storage into tab-specific Containers. Cookies downloaded by one Container are not available to other Containers. You can even integrate individual Containers with Mozilla VPN to protect your browsing and location. With the Firefox Multi-Account Containers extension, you can... - Sign in to two different accounts on the same site (for example, you could sign in to work email and home email in two different Container tabs. - Keep different kinds of browsing far away from each other (for example, you might use one Container tab for managing your Checking Account and a different Container tab for searching for new songs by your favorite band) - Avoid leaving social-network footprints all over the web (for example, you could use a Container tab for signing in to a social network, and use a different tab for visiting online news sites, keeping your social identity separate from tracking scripts on news sites) - Protect your browsing activity in individual Containers using Mozilla VPN, so you can shop while travelling abroad but check your bank account from a server in your home country. -- source: https://discuss.systems/@ricci/111024736570863186 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Connected cars are a “privacy nightmare,” Mozilla Foundation says
by Peter Reutemann 07 Sep '23

07 Sep '23

'Today, the Mozilla Foundation published its analysis of how well automakers handle the privacy of data collected by their connected cars, and the results will be unlikely to surprise any regular reader of Ars Technica. The researchers were horrified by their findings, stating that "cars are the worst product category we have ever reviewed for privacy." Mozilla looked at 25 car brands and found that all of them collected too much personal data, and from multiple sources—monitoring not just which buttons you push or what you do in any of the infotainment system's apps but also data from other sources like satellite radio or third-party maps. Or even when you connect your phone—remember that prompt asking you if you wanted to share all your contacts and notes with your car when you connected it via Bluetooth? While some gathered data seems innocuous or even helpful—feedback to improve cabin ergonomics and UIs, for example—some data is decidedly not. For example, Nissan's privacy policy says it can collect "sensitive personal information, including driver’s license number, national or state identification number, citizenship status, immigration status, race, national origin, religious or philosophical beliefs, sexual orientation, sexual activity, precise geolocation, health diagnosis data, and genetic information," although it's unlikely your car knows whether you're getting busy in the back seat. While this might be technically possible with a car fitted with a camera-based driver-monitoring system, Nissan's privacy policy notes the data source for the quoted paragraph as "direct contact with users and Nissan employees." (Although more sophisticated driver-monitoring systems that claim to detect emotional states have been demonstrated at shows like CES, we're unaware of any that are in production.) Mozilla found plenty more to worry about. Eighty-four percent of the brands they analyzed said they can share your data, and 76 percent said they can sell it. And more than half say they'll share data with the government and law enforcement by request. Users have very little control over what those brands do with their data. Only two of the 25 brands (Renault and Dacia) tell users they have the right to have their data deleted, and neither sell cars in the United States.' -- source: https://arstechnica.com/cars/2023/09/connected-cars-are-a-privacy-nightmare… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ArcaOS 5.1.0 (OEM OS/2 Warp Operating System) Now Available
by Peter Reutemann 04 Sep '23

04 Sep '23

'ArcaOS 5.1.0 is an OEM distribution of IBM's discontinued OS/2 Warp operating system. This new version of ArcaOS offers UEFI compatibility allowing it to run in modern x86 hardware and also includes the ability to install to GPT-based disk layouts. At OS2World the OS/2 community has been called upon to report supported hardware, open source any OS/2 software, make public as much OS/2 documentation as possible and post the important platform links. OS2World insists that open source has helped OS/2 in the past years and it is time to look under the hood to try to clone internal components like Control Program, Presentation Manager, SOM and Workplace Shell.' -- source: https://tech.slashdot.org/story/23/09/02/1912223 The one and only time I came across OS/2 was in the late 90s (at a bank)...
