Description

This signature detects Citadel C AND C communication on the compromised machine.

Additional Information

This signature is designed to detect Citadel communication to an infected node. Citadel is a Zeus based variant. This Trojan has primarily been designed to steal confidential information from the computers it compromises. It specifically targets system information, online credentials, and banking details, but can be customized through the toolkit to gather any sort of information. This is done by tailoring configuration files that are compiled into the Trojan installer by the attacker. These can later be updated to target other information, if the attacker so wishes.
