Whereas it’s unclear how they have been in a position to create the decryptor, it’s believed it was made doable by means of info obtained throughout this yr’s disruption of the ransomware gang.
The decryptor might be downloaded from the Japanese police’s web site, with directions shared in English. The decryptor can also be out there from Europol’s NoMoreRansom platform and is being promoted by Europol and the FBI to show its official standing.
It must be famous that internet browsers, together with Google Chrome and Mozilla Firefox, are detecting the decryptor as malware, making it troublesome to obtain and use. Nonetheless, BleepingComputer has examined the decryptor, and never solely is it not malicious, nevertheless it additionally efficiently decrypts encrypted information from latest encryptors.
The decryptor at the moment helps encrypted information with the next extensions: “.phobos“, “.8base“, “.elbie“, “.faust“, and “.LIZARD“.
Nonetheless, the Japanese police says that a number of different extensions could also be supported, so it’s price testing the decryptor even when your information wouldn’t have the listed extensions.
As a take a look at, BleepingComputer contaminated a digital machine with a latest Phobos ransomware variant that provides the .LIZARD extension to encrypted file names, as proven under.
Supply: BleepingComputer
To decrypt information, launch the decryptor and comply with its license settlement. If Home windows is just not configured to assist lengthy file names, it’ll immediate to permit it to allow this setting after which request that you simply relaunch the decryptor.

It must be famous that you would be able to choose the foundation of a drive, and the decryptor will recursively decrypt information, recreating the identical folder construction within the vacation spot folder.
As soon as full, the decryptor will show the variety of information that have been efficiently decrypted.
Supply: BleepingComputer
BleepingComputer can verify that the decryptor efficiently decrypted all 150 information encrypted by the LIZARD variant of Phobos ransomware.
Supply: BleepingComputer
Phobos and 8Base ransomware victims ought to do that decryptor, even when their encrypted information wouldn’t have one of many listed extensions, as it might nonetheless work.
