Emsisoft Decrypter for PewCrypt is a solution for the PewDiePie ransomware.

PewCrypt is a strain of ransomware written in Java that uses AES and RSA to encrypt a victim's files, adding the extension .PewCrypt. The malware then asks the victim to subscribe to PewDiePie until he gets 100 million subscribers - can't we just give millions in bitcoin? The author supposedly released this as a joke in 2019 - not so funny...

To use the decrypter, you will need the AES.key file left on the desktop by the malware. Then you will select the AES.key file by clicking the Browse button. Then click the Start button. Emsisoft Decrypter for PewCrypt will display the reconstructed encryption details once the recovery process has finished.
