A strain of malware that allows unauthorized access and control of an affected system. Linux/Ebury is a backdoor Trojan and credential stealer that disguises itself as a variant of OpenSSH for Linux and Unix-style operating systems.
In March 2014, software security firm ESET discovered a connection between Linux/Ebury and other malware components such as Linux/Cdorked, Win32/Glupteba.M and Perl/Calfbot. ESET uncovered the fact that all four malware strains are operated by the same group, and subsequently dubbed the malicious collection of components as Operation Windigo.
