OTX Bot<p>Unmasking the new XorDDoS controller and infrastructure</p><p>The XorDDoS trojan, a DDoS malware targeting Linux machines, continues to spread globally with over 70% of attacks targeting the United States from Nov 2023 to Feb 2025. The operators are believed to be Chinese-speaking individuals based on language settings. A new 'VIP version' of the XorDDoS controller and central controller have been discovered, enabling more sophisticated and widespread attacks. The malware uses SSH brute-force attacks to gain access and implements persistence mechanisms. A new central controller allows threat actors to manage multiple sub-controllers simultaneously, enhancing attack coordination. The infection chain, decryption methods, and network communication patterns between the trojan, sub-controller, and central controller are analyzed in detail.</p><p>Pulse ID: 6800fccf8db6537ac15e75fb<br>Pulse Link: <a href="https://otx.alienvault.com/pulse/6800fccf8db6537ac15e75fb" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">otx.alienvault.com/pulse/6800f</span><span class="invisible">ccf8db6537ac15e75fb</span></a> <br>Pulse Author: AlienVault<br>Created: 2025-04-17 13:06:23</p><p>Be advised, this data is unverified and should be considered preliminary.
