Blower is a ransomware that is a part of the Djvu family. It is similar to other viruses like CryptoID888, and Cosanostra.



The malicious payload is usually injected with the help of illegal cracks and keygens, usually downloaded from torrent sites.


Blower virus uses AES cipher to lock data and appends .blower extension – the encryption process usually takes only a few seconds, so victims cannot do much to stop it. Databases, documents, pictures, and other data becomes inaccessible, and users are shown a _readme.txt note that explains what happened, and they are asked for a ransom of $490 in bitcoin for the file release. Bad actors also clarify that the amount doubles if the sum is not transferred within 72 hours of the infection.

The Blower Ransomware targets the user-generated files, such as those with the following extensions:
