Lock93 is ransomware that likely targets users in Russia. It encrypts files on an affected computer and demands 1000 Russian rubles for a decryption key.
The .lock93 file is not an independent document format. It is an encrypted version of the original file, and its contents cannot be identified reliably from the renamed extension alone. The format is specific to files affected by Lock93 ransomware.
A .lock93 file cannot be opened normally by a document, image, or media application. Access to the original data requires decrypting the file with a working Lock93 decryption method or key. No way to decrypt these files is known at this time.
A .lock93 file cannot be usefully converted while it remains encrypted. After the data has been decrypted, the recovered file can be opened or converted using an application that supports its original format.
