Astralocker

AstraLocker is a variant of malware, specifically a ransomware that was discovered by researchers from ReversingLabs last year. It is a new strain derived from the Babuk ransomware-as-a-service, which has been used as a basis for several other spinoff families such as Nokoyawa, AstraLocker 2.0, ESXiArgs, Team Daixin, and HelloXD. This particular form of malware proliferated in smash-and-grab attacks, causing significant disruption and damage. In June 2022, an updated version of this ransomware, known as AstraLocker 2.0, emerged. The AstraLocker ransomware became notorious for its ability to infiltrate systems, often through suspicious downloads, emails, or websites, steal personal information, disrupt operations, and hold data hostage for ransom. However, in July 2022, reports indicated that the AstraLocker ransomware had ceased operations to pursue cryptojacking, a form of cyber attack where hackers use victims' computing resources to mine cryptocurrencies without their consent. Despite the challenges posed by AstraLocker, efforts have been made to counteract its effects. Free decryptors for AstraLocker ransomware have been released, providing victims with tools to regain access to their encrypted data without paying a ransom. This includes a free decryptor for both AstraLocker and Yashma Ransomware, developed by Emsisoft. These developments represent significant strides in combating the threat posed by these malicious software variants.
