released on 2022-07-07 @ 12:07:14 PM
In this blog Intezer will provide a deep technical analysis of a new and fully undetected Linux threat Intezer named OrBit, because this is one of the filenames that is being used by the malware to temporarily store the output of executed commands. It can be installed either with persistence capabilities or as a volatile implant. The malware implements advanced evasion techniques and gains persistence on the machine by hooking key functions, provides the threat actors with remote access capabilities over SSH, harvests credentials, and logs TTY commands. Once the malware is installed it will infect all of the running processes, including new processes, that are running on the machine.
