Pywdu Virus – Details
The Pywdu mean a ransomware-type infection. The infection comes from the Snatch ransomware family. Pywdu was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Pywdu adds the “.pywdu” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Pywdu, will be renamed into “myphoto.jpg.pywdu“. As soon as the encryption is finished, Pywdu places a special text file into every folder containing the encrypted data.The message given by Pywdu text file requesting for the ransom is definitely the like the statements given by other ransomware representatives belonging to the Snatch type. It literally discusses that the information is encrypted and that the only way to restore it is to use a an unique decryption key. Regretfully, this is absolutely true. The sort of cryptography mechanism applied by Pywdu is still not appropriately examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is completely distinct. It is difficult to bring back the files without the key available.
Another technique of Pywdu is that the victims cannot access to the key. The key is saved on a specific server run by the frauds associated with Pywdu ransomware. To get the key and recover the important info people need to pay the ransom.
Pywdu encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.
