What is ZeroCool Ransomware

ZeroCool Ransomware is a type of malware that encrypts files on the victim’s computer. In addition to encrypting data, ZeroCool adds the .ZeroCool extension to filenames and provides a ransom note (ZeroCool_Help.txt). This ransomware poses significant challenges to individuals, businesses, and governments due to its ability to disrupt operations, compromise data, and extract ransom payments. Modern ransomware, like ZeroCool, often uses a hybrid encryption scheme, combining AES and RSA encryption to secure their malware against researchers recovering encrypted files. This approach involves generating an RSA key pair, encrypting all files with the public key, and sending the private key to the server to be stored. Below you can see an example of the ransom note:

Your ID : -
In subject line please write your personal ID
Do not delete or modify encrypted files, it will lead to problems with decryption of files!
If you don't pay the ransom, the data will be published on our TOR darknet sites.
Keep in mind that once your data appears on our leak site, it could be bought by your competitors at any second, so don't hesitate for a long time.
The sooner you pay the ransom, the sooner your company will be safe.
What guarantee is there that we won't cheat you?
Send us ONE small encrypted files to emails listed below.
We will decrypt these files and send them back to you as a proof.

As there are no known decryption tools for ZeroCool ransomware, the best course of action is to restore your files from a backup if you have one. If you don’t have a backup, you can try using general-purpose decryption tools or data recovery software, but there is no guarantee that these methods will work. It is not recommended to pay the ransom, as there is no guarantee that the attackers will provide a working decryption key, and paying the ransom encourages further criminal activity.
