ZeroCool Ransomware Threatens Leaking Data
The ZeroCool ransomware is a form of malicious software that encrypts files. Alongside the encryption process, ZeroCool appends the ".ZeroCool" extension to the filenames and delivers a ransom message in a file called "ZeroCool_Help.txt." To illustrate how ZeroCool alters file names, for instance, "1.jpg" becomes "1.jpg.ZeroCool," and "2.png" transforms into "2.png.ZeroCool."
The ransom note informs the victim that their crucial files have been taken and encrypted. It provides two email addresses, zero.cool2000@onionmail.org and zero.cool2000@skiff.com, as a means of contacting the perpetrators and instructs the victim to include their personal ID in the subject line when reaching out.
This note also issues a stern warning against deleting or altering the encrypted files, as such actions would complicate the decryption process. It goes on to threaten that failing to pay the ransom could result in the data being disclosed on Tor darknet websites, potentially allowing competitors to acquire it. The note underscores the urgency of promptly paying the ransom to ensure the safety of the victim's company.
To assure the victim of the cybercriminals' intentions, the note directs them to send a small encrypted file to the provided email addresses. The promise is that the attackers will decrypt this file and return it as proof of their capability to restore the encrypted data.

Regular Backups: Maintain up-to-date backups of your critical data on offline or cloud storage. Regularly test your backups to ensure they can be restored successfully in case of an attack. This is one of the most effective ways to recover your data without paying a ransom.
