LockBit Black 3.0

LockBit Black 3.0, also referred to in the content as LockBit 3.0, is a ransomware family observed in campaigns that abuse legitimate, digitally signed IT administration and troubleshooting tools to evade detection and disable defenses. Seqrite reported this tactic as part of a broader "dual-use dilemma" in ransomware operations. In the described attack chains, intrusions often begin with phishing emails or compromised or stolen credentials, followed by privilege escalation using tools such as PowerRun for SYSTEM-level access or YDArk for kernel-level access. Operators then use process-killing utilities, including trusted tools such as IOBit Unlocker and Process Hacker, to terminate antivirus or security monitoring processes. The campaigns also use Mimikatz for credential theft and Unlock_IT to erase logs and hinder forensic investigation. The content further notes that modern Ransomware-as-a-Service offerings such as LockBit 3.0 increasingly bundle antivirus-killing capabilities. High-confidence indicators and associated tooling mentioned in connection with LockBit Black 3.0 campaigns include IOBit Unlocker, Process Hacker, PowerRun, YDArk, Mimikatz, and Unlock_IT.
