VERY IMPORTANT

A few months back, Intezer and BlackBerry researchers discovered a new, undetected Linux malware that acts in this parasitic nature. They have aptly named this malware Symbiote. What makes Symbiote different from other Linux malware that they usually come across, is that it needs to infect other running processes to inflict damage on infected machines. Instead of being a standalone executable file that is run to infect a machine, it is a shared object (SO) library that is loaded into all running processes using LD_PRELOAD (T1574.006), and parasitically infects the machine. Once it has infected all the running processes, it provides the threat actor with rootkit functionality, the ability to harvest credentials, and remote access capability.
