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 uses a combination of RSA-2048 and AES-256 encryption algorithms to encrypt victims' files and employs "double extortion" tactics. The group typically demands payment in Bitcoin, ranging from several thousand to several hundred thousand dollars.
Potential Vulnerabilities
eFile.com's significant online presence and the sensitive nature of the data it handles make it an attractive target for ransomware groups like LockBit. The platform's reliance on digital infrastructure for tax preparation and e-filing services could have been exploited through vulnerabilities in Remote Desktop Protocol (RDP) services or unsecured network shares. LockBit is known for its ability to spread quickly across networks, making robust cybersecurity measures essential for platforms like eFile.com.
