Intezer Security has found a new backdoor, ACBackdoor, that has no known connection to an operating threat group creating the possibility it could be a harbinger of a new gang’s formation.

One piece of evidence pointing toward the ACBackdoor developers being experienced with Linux is that version has a lower detection rate, is written better than the Windows implant, with a higher quality persistence mechanism, along with the different backdoor commands and additional features not seen in the Windows version such as independent process creation and process renaming.
