What is Anatova ransomware? And how does it carry out its attack?

Anatova ransomware is a new file-encrypting virus discovered in the middle of January 2019. Like a typical ransomware threat, it is designed to encrypt important files in a computer and extort money from victims in the form of 10 Dash coins as payment in exchange for the recovery of the encrypted files.

Once its malicious payload named “CallOfCthulhu.exe” is dropped in the system, Anatova ransomware will begin to carry out its attack. It starts by establishing a connection between the system and a remote C&C server controlled by the attackers. The crypto-malware will then download its other components from this remote server. These malicious components are then placed on system folders. They will be used for the data gathering and stealth protection modules. The first module is the one that obtains data from the system. The obtained data, along with some other components are then used for the stealth protection module which is the one that bypasses security programs, sandbox environments and antivirus programs installed in the system. These aforementioned programs may be disabled or removed completely to prevent them from interfering with the attack. Moreover, Anatova ransomware also messes with some registry entries in the Windows Registry, allowing it to run automatically on every system startup. Once all the system modifications are applied, Anatova ransomware will begin the encryption using the AES cipher. After the encryption, affected files will become unusable and inaccessible. These compromised files are not known to get any special or custom extension so it’s really hard to tell which files are encrypted and which ones are not unless you open each one of them. Anatova ransomware will open a text file named “ANATOVA.txt” which contains the following message:

“All your files are crypted. Only us can decrypt your files, you need pay 10 DASH in the address:

XpRvUwSjSeHfJqLePsRfQtCKa1VMwaXh12

After the payment send us the address used to make the payment to one of these mail addresses:

anatova2@tutanota.com

anatoday@tutanota.com

Later wait for our reply with your decryptor. If you want can send us ONE JPG FILE ONLY max 200kb to decrypt per free before of payment.

Dont try fuck us, in this case you NEVER will recover your files. Nothing personal, only business.

Send this file untouched with your payment or/and free file!
