SystemBC is a previously undocumented malware that we have recently observed as a payload in both RIG and Fallout exploit kit (EK) campaigns. While EK activity has remained quite low relative to its peak in early 2016, exploit kits remain important vectors for malware distribution, particularly in regions where Windows piracy is common. The new malware utilizes SOCKS5 proxies to mask network traffic to and from Command and Control (C&C) infrastructure using secure HTTP connections for well-known banking Trojans such as Danabot, which we have also observed distributed in the same EK campaigns.
