∗∗∗ New Spectre v2 attack impacts Linux systems on Intel CPUs ∗∗∗ --------------------------------------------- Researchers have demonstrated the "first native Spectre v2 exploit" for a new speculative execution side-channel flaw that impacts Linux systems running on many modern Intel processors. [..] The hardware vendor has indicated that future processors will include mitigations for BHI and potentially other speculative execution vulnerabilities. For a complete list of impacted Intel processors to the various speculative execution side-channel flaws, check this page updated by the vendor. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-spectre-v2-attack-impacts...

∗∗∗ DragonForce Ransomware - What You Need To Know ∗∗∗ --------------------------------------------- A relatively new strain of ransomware called DragonForce has making the headlines after a series of high-profile attacks. Like many other ransomware groups, DragonForce attempts to extort money from its victims in two ways - locking companies out of their computers and data through encryption, and exfiltrating data from compromised systems with the threat of releasing it to others via the dark web. So far, so normal. How did DragonForce come to prominence? --------------------------------------------- https://www.tripwire.com/state-of-security/dragonforce-ransomware-what-you-n...

∗∗∗ Metasploit Meterpreter Installed via Redis Server ∗∗∗ --------------------------------------------- Redis is an abbreviation of Remote Dictionary Server, which is an open-source in-memory data structure storage that is also used as a database. It is presumed that the threat actors abused inappropriate settings or ran commands through vulnerability attacks. --------------------------------------------- https://asec.ahnlab.com/en/64034/
∗∗∗ Control Web Panel - Fingerprinting Open-Source Software using a Consolidation Algorithm approach ∗∗∗ --------------------------------------------- This blog post details one of these very unique cases: `CVE-2022-44877`, an unauthenticated Command Injection issue, flagged by CISA as a Known Exploited Vulnerability (CISA KEV), affecting Control Web Panel, an open-source control panel for servers and VPS management. Initially, the team could not find a way to straightforwardly fingerprint the software’s version, nor another way to detect it without intrusive exploitation - thus we used a novelty technique: an algorithm that retrieves the web application’s static web content files and consolidates them to pin-point the software’s version. --------------------------------------------- https://www.bitsight.com/blog/control-web-panel-fingerprinting-open-source-s...
