About LockBit Ransomware Group
LockBit is a highly sophisticated ransomware-as-a-service (RaaS) group that has been 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, making it extremely difficult to recover data without paying the ransom.
Potential Vulnerabilities
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 attack on T. Philips Kierl Jr. & Associates underscores the importance of cybersecurity measures, especially for firms handling sensitive financial data.
