SystemBC malware is recently being distributed through Emotet and SmokeLoader. The malware has been used in multiple ransomware attacks over the past few years. SystemBC acts as a Proxy Bot and if an infected system has SystemBC on it, then the system can be used as a passage to access the victim’s address.
