Infected with PayDay ransomware? Need to decrypt your files?
What is PayDay ransomware
Payday is a ransomware based on HiddenTear source code and developed by Portuguese hackers. Payday derives its name from popular game of the same name. The purpose of the infection is to deny access to the personal data so it encrypts them using complex AES cipher. At the time of encryption, Payday appends the names of encrypted files with the .sexy extension. Although, the data encryption is a time-consuming process, the users usually don’t notice nothing suspicious. The whole procedure runs in stealth mode. Once encrypted, virus creates HTML file saving it on the desktop. This file contains a ransom note in Portuguese which inform victims of the encryption. The ransom-demand message (“!!!!!ATENÇÃO!!!!!.html“)states that files are encrypted and now the user has to pay up within 5 days to restore files. Despite the fact that currently no tools capable of restoring data infected by PayDay ransomware, you shouldn’t do any payment because victims are often ignored once payments are submitted. The only way is to restore your data from a backup.
