Summary: ThreatLabz observed an update to the Ares banking trojan that introduces a domain generation algorithm (DGA), which mirrors the Qakbot DGA. Based on analyzing the malware code, there does not appear to be a direct link between these two malware families. The Ares DGA may be an effort for the threat actor to maximize the lifetime of an infection, which provides more opportunities for monetizing compromised systems through attacks such as wire fraud and ransomware.…
