What is CryptoGod ransomware? And how does it implement its attack?
CryptoGod ransomware is a file-encrypting virus which is created based on the HiddenTear ransomware – an open source platform that was developed initially for educational purposes but was exploited by cybercriminals. At the time of writing, it seems that the current samples released from this crypto-malware are test versions but it could be updated any time soon.
According to security experts, CryptoGod ransomware was created by a hacker named “Patrizio Napoli” as his signature was found in the ransomware’s code. Since this ransomware is still under development, it does not feature any modules on its attack yet. However, this ransomware must still not be taken lightly as it could be updated by its creator. Once it encrypts a targeted machine, it will start to encrypt targeted files using the AES encryption algorithm. It may target user-generated files like archives, images, music, documents, videos, database and many more. The compromised files are then appended with the .locked extension. After it marks its encrypted files, it opens a lock screen instance which contains the following message:
“I TUOI FILE PERSONALI STANNO PER ESSERE
CANCELLATI. LE TUE FOTO, VIDEO, DOCUMENTI
MA NON PREOCCUPARTI! SUCCEDERA SOLO SE
