∗∗∗ Researchers Uncover Malware Using BYOVD to Bypass Antivirus Protections ∗∗∗ --------------------------------------------- Cybersecurity researchers have uncovered a new malicious campaign that leverages a technique called Bring Your Own Vulnerable Driver (BYOVD) to disarm security protections and ultimately gain access to the infected system. [..] The starting point of the attack is an executable file (kill-floor.exe) that drops the legitimate Avast Anti-Rootkit driver, which is subsequently registered as a service using Service Control (sc.exe) to perform its malicious actions. --------------------------------------------- https://thehackernews.com/2024/11/researchers-uncover-malware-using-byovd.ht...

∗∗∗ Dozens of Machines Infected: Year-Long NPM Supply Chain Attack Combines Crypto Mining and Data Theft ∗∗∗ --------------------------------------------- The package, @0xengine/xmlrpc, began its life as a “legitimate” XML-RPC implementation in October 2023, but strategically transformed into a malicious tool in later versions and has remained active through November of 2024. This discovery serves as a stark reminder that a package’s longevity and consistent maintenance history do not guarantee its safety. --------------------------------------------- https://checkmarx.com/blog/npm-supply-chain-attack-combines-crypto-mining-an...
