ESET Crysis Decryptor review
A focused, free decryptor for supported Crysis/Wallet variants, with command-line options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ESET Crysis Decryptor is a free Windows utility for recovering files affected by certain Crysis ransomware variants. It is aimed at Windows users whose files match the supported variants, rather than people seeking a general-purpose ransomware recovery tool. The utility scans a selected drive and supports files with extensions including .xtbl, .crysis, .crypt, .lock, .crypted, .dharma, .wallet, and .onion.
Its focus is narrow, but the workflow has useful command-line controls. ESET's support instructions describe running the executable from an elevated Windows command prompt and selecting a drive to scan. Command-line switches provide usage help, and the tool also supports silent and debug modes. That makes it suited to users who want to control a scan through Windows command prompt options; it is a desktop utility, not a broader recovery platform.
The published offering is a single free decryption utility, so there are no paid tiers to weigh against its features. The key constraint is compatibility: ESET says the latest version was released in 2017 and does not support the most recent Win32/Filecoder.Crysis variants. Choose it when the affected files are from a supported Crysis/Wallet variant and the Windows command-line workflow fits. If the infection is from a newer variant or outside that family, this tool is not the right fit.
