This malware seems to have evolved from the open-source Windows backdoor Trochilus. The backdoor showcases swift behavior and a SOCKS implementation, hence the name. 🐍💼</p><p>SprySOCKS's structure is reminiscent of the RedLeaves backdoor, a RAT known to infect Windows machines. This backdoor is still under development, with different versions observed. Its interactive shell seems to draw inspiration from the Linux variant of the Derusbi malware. 🕵️♂️🔍</p><p>Recent activities of Earth Lusca indicate a focus on Southeast Asia, Central Asia, and the Balkans. Their primary targets? Government departments in foreign affairs, technology, and telecommunications. They've been exploiting server-based N-day vulnerabilities, including CVE-2022-40684, CVE-2022-39952, and more. Once inside, they deploy Cobalt Strike for lateral movement, aiming to exfiltrate sensitive data and conduct long-term espionage. 🌍🎯</p><p>Source: <a href="https://www.trendmicro.com/en_us/research/23/i/earth-lusca-employs-new-linux-backdoor.html" rel="nofollow noopener" target="_blank">Trend Micro Research</a></p><p>Tags: <a href="https://infosec.exchange/tags/EarthLusca" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>EarthLusca</span></a> <a href="https://infosec.exchange/tags/SprySOCKS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SprySOCKS</span></a> <a href="https://infosec.exchange/tags/LinuxBackdoor" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LinuxBackdoor</span></a> <a href="https://infosec.exchange/tags/CyberSecurity" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CyberSecurity</span></a> <a href="https://infosec.exchange/tags/APT" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>APT</span></a> <a href="https://infosec.exchange/tags/ThreatIntelligence" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ThreatIntelligence</span></a> <a href="https://infosec.exchange/tags/RedLeaves" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RedLeaves</span></a> <a href="https://infosec.exchange/tags/Trochilus" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Trochilus</span></a> <a href="https://infosec.exchange/tags/CobaltStrike" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CobaltStrike</span></a> 🌐🔐🖥️</p>
