Actions to be taken You should upgrade your Microsoft Windows to newer versions, if your hardware does not support Windows 11, you may upgrade to Windows 10 or maybe consider switching to another Operation System like Linux. ...

You’ve heard it again and again: You need to use a password manager to generate strong, unique passwords and keep track of them for you. And if you finally took the plunge with a free and mainstream option, particularly during the 2010s, it was probably LastPass. For the security service’s 25.6 million users, though, the company made a worrying announcement last week: A security incident the firm previously reported on November 30 was actually a massive and concerning data breach that exposed encrypted password vaults—the crown jewels of any password manager—along with other user data. ...

The Intel Security Advanced Threat Research Team has discovered a critical signature forgery vulnerability in the Mozilla Network Security Services (NSS) crypto library that could allow malicious parties to set up fraudulent sites masquerading as legitimate businesses and other organizations. The Mozilla NSS library, commonly utilized in the Firefox web browser, can also be found in Thunderbird, Seamonkey, and other Mozilla products. Dubbed “BERserk”, this vulnerability allows for attackers to forge RSA signatures, thereby allowing for the bypass of authentication to websites utilizing SSL/TLS. Given that certificates can be forged for any domain, this issue raises serious concerns around integrity and confidentiality as we traverse what we perceive to be secure websites. ...

Apple has released a security update for its QuickTime media framework for Windows. Version 7.7.4 of the software closes 12 critical security holes causing memory corruption and buffer overflows when processing a number of media formats. The vulnerabilities affect Windows 7, Vista and XP SP2 or later and could be exploited to cause arbitrary code execution and application crashes. The vulnerabilities affected the playback of MP3, H.263, H.264, TeXML, JPEG, QTIF, Sorenson Video and FPX files as well as the handling of dref, enof and mvhd atoms within the program. All of the problems were reported by researchers working with HP’s Zero Day Initiative, five of them by Tom Gallagher and Paul Bates from Microsoft. ...

Symantec vs AV-Comparatives, Which one do you trust?

Cross-posted from PCMag SecurityWatch: Last week independent antivirus lab AV-Comparatives released the results of an on-demand antivirus detection test. The fact that Microsoft came in near the bottom wasn’t big news; the fact that Symantec scored even lower was surprising indeed. In a blog post released today, Symantec decried the entire practice of performing on-demand malware scanning tests, calling it “misleading.” In the early years of antivirus testing, every test was an on-demand scanning test. Researchers would assemble a collection of known malware, run a full scan, and record the percentage of samples detected. Modern labs work hard to devise tests that more closely reflect a user’s real-world experience, taking into account the fact that the vast majority of infections enter the computer from the Internet. Symantec contends that only the real-world sort of test is valid; I don’t entirely agree. ...

A new security option gives Apple’s customers a way to secure their Apple ID password using their phone. Cross-posted from Cnet: Apple today added an extra layer of security to its Apple ID system that can harden the password people use to log in to various Apple services. Users with an Apple ID can now sign up for two-step verification of their password, a system that sends a four-digit passcode by text message to a user’s phone, and must be used on top of a regular password. In practice, this could keep an account from being compromised by an attacker, unless that person had access to the mobile device too. ...
