Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
10 distinct techniques documented for this family, organized by ATT&CK tactic.
The rootkits act as UDP listeners accepting packets on any IP assigned to the device, permitting remote execution of malicious commands.
The core vulnerability exploited is CVE-2025-20352, a stack overflow flaw in the Simple Network Management Protocol (SNMP) subsystem of Cisco devices. It allows authenticated remote attackers to execute arbitrary code by sending specially crafted SNMP packets.
Once exploited, attackers gain remote code execution (RCE) capabilities and implant sophisticated Linux rootkits. These rootkits operate largely filelessly by hooking into the Cisco IOS daemon (IOSd) memory, enabling persistent and stealthy control of the infected switches.
Attackers can disable or delete device logs to erase traces of their presence. They reset the last running-config write timestamp to make changes appear non-existent.
They set a universal password containing the string “disco” (a subtle alteration of “Cisco”), allowing unauthorized access through multiple authentication methods.
