Malware Advertised in Hacking Forums

As the malware spotted in multiple campaigns, Proofpoint researchers checked with the underground marketplace for the existence of the malware. “we found an advertisement from April 2, 2019, on an underground forum that described a malware named “socks5 backconnect system” that matched the functionality of the malware seen in the above campaigns.”

To differentiate from other malware using SOCKS5, the malware is named as SystemBC, the advertisement also details the C&C servers, list of victim machines and authentication.

The SystemBC malware written in C++ and it set’s up tunnel network in the infected machine to hide the traffic associated with other malware. The connection between the Command and Control are encrypted using RC4.

SystemBC Advertised as Below

• loader with update function every N hours (for long survivability it is necessary to update the crypts)
• firewall (access to socks only from trusted ip)
• authorization on socks by login and password
• GeoIP

Proofpoint published a detailed report, that covers the functionality and the detailed analysis report including the Indicators of Compromise.

Administrators are recommended to remain vigilant to keep the Windows client and server’s updated and the infrastructure devices patched and retire legacy systems.
