CrowdStrike has released a free decryption tool capable of recovering files encrypted by LockBit 4.0 ransomware variants, after the company's researchers discovered a cryptographic weakness in the malware's key generation algorithm.
The tool supports all known LockBit 4.0 sub-variants and works on both Windows and Linux systems. CrowdStrike estimates that the decryptor could help thousands of organizations currently locked out of their data without paying ransom demands.
The release represents a significant blow to the LockBit ransomware operation, which has extorted hundreds of millions of dollars from victims worldwide since its emergence in 2019.
