About LockBit
LockBit, also known as LockBit Black, is a highly sophisticated ransomware-as-a-service (RaaS) group active since September 2019. It has become the most active ransomware group, responsible for over one-third of all ransomware attacks in the latter half of 2022 and the first quarter of 2023. LockBit employs "double extortion" tactics, exfiltrating sensitive data and threatening to release it publicly if the ransom is not paid. The ransomware uses a combination of RSA-2048 and AES-256 encryption algorithms to encrypt victims' files.
Potential Vulnerabilities and Penetration Methods
LockBit is designed to exploit vulnerabilities in Remote Desktop Protocol (RDP) services and unsecured network shares to spread quickly across a network. It performs a check to avoid executing on computer systems with installed languages common to the Commonwealth of Independent States (CIS) region. Indicators of Compromise (IOCs) for LockBit include the creation of a mutual exclusion object (Mutex) when executed, the use of a unique icon, and changes to the victim's computer wallpaper. The ransomware group distinguishes itself by its modular design, which encrypts its payload until execution to hinder malware analysis and detection.
