Written in language Go and based on complex DLL sideloading techniques, it was designed to remain silent and continuously collect and exfiltrate sensitive information.

RDStealer, the new China-based malware targeted by Bitdefender

Bitdefender has not assigned a specific group of cybercriminals, however, the level of complexity and objectives are consistent with an APT based in Chinese. What makes RDStealer unique is its ability to compromise clients’ downstream connections Remote Desktop Protocol (RDP).

When an incoming RDP connection meeting certain criteria is detected, the compromised RDP host infects the connecting client with a backdoor and attempts to exfiltrate valuable data such as credentials or certificates.
