Stealthy RotaJakiro Backdoor Targeting Linux Systems

Previously undocumented and stealthy Linux malware named RotaJakiro has been discovered targeting Linux X64 systems. It has been undetected for at least three years, and operates as a backdoor.

Four samples have now been discovered, all using the same C2s. The earliest was discovered in 2018. None of the samples were labeled malware by VirusTotal.
