Windigo, also known as the Windigo Gang, is a cybercriminal Linux server-compromise operation centered on the Ebury trojanized OpenSSH backdoor and credential stealer. The operation deployed multiple associated malware components, including Ebury, Cdorked, Calfbot, Helimod, and Onimiki, against Linux servers. Ebury enables stealthy persistent access by modifying OpenSSH components and can capture SSH credentials handled by affected servers or clients. Windigo operators used scripts to profile compromised Linux hosts, including identifying the installed distribution and version, checking for artifacts associated with other OpenSSH backdoors, and gathering credentials left by such backdoors. The operators' use of signatures to identify competing OpenSSH implants before deploying Ebury indicates reconnaissance and competition-aware post-compromise activity. Ebury was documented on tens of thousands of compromised Linux servers worldwide.
