Initially functioning as a banking trojan, BianLian transitioned into advanced ransomware operations, emphasizing extortion-based strategies. The group gained initial access through compromised Remote Desktop Protocol (RDP) credentials, implanting custom backdoors specific to each victim, using PowerShell and Windows Command Shell for defense evasion, and employing various tools for discovery, lateral movement, collection, exfiltration, and impact.
