Security News > 2024 > February > Free Rhysida ransomware decryptor for Windows exploits RNG flaw
South Korean researchers have publicly disclosed an encryption flaw in the Rhysida ransomware encryptor, allowing the creation of a Windows decryptor to recover files for free.
Victims of the Rhysida ransomware may use the tool to try to decrypt their files for free, but BleepingComputer cannot guarantee the tool's safety or effectiveness.
Ransomware expert Fabian Wosar told BleepingComputer that this decryptor only works for encrypted files by the Rhysida Windows encryptor and cannot decrypt files encrypted on VMware ESXi or via its PowerShell-based encryptor.
The Rhysida encryption flaw has been privately used for months by cybersecurity firms and governments worldwide since at least May 2023.
