Imshifau Ransomware

Imshifau Ransomware Description

The Imshifau Ransomware is a threat that can cause massive damage to the systems it manages to infect. By utilizing strong cryptographic algorithms, the threat is capable of locking the most widely-used filetypes including documents, PDFs, databases, archives, images, photos, etc. Users will find themselves unable to access the affected files at all. The Imshifau Ransomware changes the names of the encrypted files completely. It substitutes them with a random string followed by the '.Imshifau' extension. Victims will be left with a ransom note placed inside a text file named 'INFO OF DECRYPT.TXT.' The note-bearing file will be generated on the Desktop of the affected device.

The message doesn't mention the exact sum demanded by the hackers as ransom. However, the users are warned, that if they do not establish contact within 72 hours the price will be increased. Two email addresses are provided as means of communication - 'Imshifau@tutanota.com' and 'Imshifau@vegeta.cyou.' Victims can attach up to three files to their initial message that will then will supposedly be decrypted and returned. The files must not exceed 5MB in total size or containing valuable data.
