C0XMO
Intelligence Profile
According to FortiGuard Labs, C0XMO is a newly identified Gafgyt variant that propagates by exploiting CVE-2021-27137 in DD-WRT routers, enabling remote attackers to control vulnerable systems. Unlike traditional Gafgyt, C0XMO modularizes its lateral movement into a standalone Python script, allowing it to efficiently target multiple Linux architectures. The malware is written in both Python and compiled ELF binaries, and features persistence, competitor process termination, and a broad set of DDoS attack methods. Its architecture is more advanced than typical Gafgyt, with separate scanning and propagation components, extensive exploitation capabilities, and improved scalability for botnet deployment.
Threat Analysis
C0XMO is a advanced-sophistication threat actor of undetermined national origin, engaged in cyber operations with a primary motivation of espionage.
The group's espionage-oriented operations suggest a state-sponsored or state-aligned mandate, typically focused on stealing intellectual property, government secrets, or military intelligence. Targets are usually selected for strategic value rather than financial gain.
Classified as an advanced threat actor, C0XMO likely develops or acquires zero-day exploits, employs custom malware toolchains, and demonstrates long-term persistence capabilities — hallmarks of a well-resourced operation consistent with nation-state backing.
