cisa kev vulnerability prioritization
cisa kev vulnerability prioritization Most Linux teams don't struggle to find vulnerabilities anymore. They struggle to decide which ones deserve attention first. Between daily scanner results, vendor advisories, and hundreds of new CVEs each month, the challenge isn't visibility—it's prioritization. . To solve this, organizations typically lean on the National Vulnerability Database (NVD) and CISA’s Known Exploited Vulnerabilities Catalog. But these aren’t competing lists. They answer two entirely different questions. While the...

Desktop Securitysecurity advisory vulnerability
security advisory vulnerability GNOME is officially shortening its standard vulnerability disclosure window from 90 days to 30 days, a change that impacts upstream maintainers, downstream Linux distributions, and system administrators in how they handle software vulnerabilities. The policy shift, announced by long-time security coordinator Michael Catanzaro , addresses modern software patching realities and a growing influx of automated submissions. . Because GNOME is the default desktop environment on several major Linux...

data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

attackransomwareencryption flawFirst Linux Clop Ransomware Variant: Flawed Encryption Revealed
The first-ever Linux variant of the Clop ransomware has been detected in the wild, but with a faulty encryption algorithm that has made it possible to reverse engineer the process. . "The ELF executable contains a flawed encryption algorithm making it possible to decrypt locked files without paying the ransom," SentinelOne researcher Antonis Terefos said in a report shared with The Hacker News. The cybersecurity firm, which has made available a decryptor , said it observed the ELF version on December 26, 2022, while also noting its similarities to the Windows flavor when it comes using the same encryption method. The detected sample is said to be part of a larger attack targeting educational institutions in Colombia, including La Salle University, around the same time. The university was added to the criminal group's leak site in early January 2023, per FalconFeedsio . The link for this article located at The Hacker News is no longer available. .

malwareransomwaresecurity threatClop Ransomware Targets Linux Servers With Encryption Flaw
The Clop ransomware gang is now also using a malware variant that explicitly targets Linux servers, but a flaw in the encryption scheme has allowed victims to quietly recover their files for free for months. . This new Linux version of Clop was spotted in December 2022 by Antonis Terefos, a researcher at SentinelLabs , after the threat group used it together with the Windows variant in an attack against a university in Colombia. While very similar to the Windows version, as they both use the same encryption method and almost identical process logic, there still are some differences, mainly limited to OS API calls and features still waiting to be implemented in the Linux variant. .

It has been discovered that the RansomExx ransomware gang does not correctly lock Linux files during encryption, leading to potentially corrupted files. . In a new report by Profero, Senior Incident Responder Brenton Morris says the RansomEXX decryptor was failing on various files encrypted by the threat actor's Linux Vmware ESXI encryptor for one the victims who paid the ransom. After reverse-engineering the RansomExx Linux encryptor, Profero discovered that the problematic decryption was caused by Linux files not being adequately locked while they were encrypted. .

security advisoryDoSencryption flawCritical Vulnerability in Facebook Fizz TLS: DoS Exploit Discovered
Researchers have found a vulnerability in the open-source Facebook Fizz project which is relatively easy to trigger for the purposes of a denial-of-service (DoS) attack. . Facebook Fizz is an open-source TLS 1.3 library written in C++ 14. TLS is one of the newer encryption standards for the Internet available and has been designed to be the successor to SSL. TLS implements stronger encryption standards and also has removed support for older, less secure algorithms. The link for this article located at ZDNet is no longer available. .

network securitycryptographic weaknesskey exchangeWarning: NSA Can Eavesdrop On Trillions Of Encrypted Connections
For years, privacy advocates have pushed developers of websites, virtual private network apps, and other cryptographic software to adopt the Diffie-Hellman cryptographic key exchange as a defense against surveillance from the US National Security Agency and other state-sponsored spies. Now, researchers are renewing their warning that a serious flaw in the way the key exchange is implemented is allowing the NSA to break and eavesdrop on trillions of encrypted connections. . The cost for adversaries is by no means modest. For commonly used 1024-bit keys, it would take about a year and cost a "few hundred million dollars" to crack just one of the extremely large prime numbers that form the starting point of a Diffie-Hellman negotiation. But it turns out that only a few primes are commonly used, putting the price well within the NSA's $11 billion-per-year budget dedicated to "groundbreaking cryptanalytic capabilities." .

Computer security experts said they've found a new encryption flaw closely related to one found earlier this year that puts Web surfers' data at risk. . The flaw, called LogJam, can allow an attacker to significantly weaken the encrypted connection between a user and a Web or email server, said Matthew D.
