Agent.Spyware.Stealer.DDS is a detection name used by various antivirus engines to classify a Trojan designed to steal sensitive information from infected systems. This spyware can extract login credentials, banking details, and other confidential data while running stealthily in the background. Additionally, it can serve as a gateway for other malware, posing a severe security risk.
