Checkmate ransomware overview

Although Checkmate ransomware is new, we can already provide an overview based on the information supplied by the attack to QNAP, a provider of quality network devices:

‘A new ransomware known as Checkmate has recently been brought to our attention. Once the attacker successfully logs in to a device, they encrypt data in shared folders and leave a ransom note.’

Ransomware targets NAS devices by bypassing weak passwords and misconfigured networks.

When the user logs in, the malware encrypts data and modifies the extensions from, for example, ‘1.docx’ to ‘1.docx.checkmate’.

After that, a ransom note appears with the file name: ‘!CHECKMATE_DECRYPTION_README’.

Is Checkmate a virus?

Checkmate is not a virus but ransomware that encrypts files and demands payment to recover the data.

But, in most cases, the hackers do not return the money and demand more, even if you pay the requested amount.

The solution to avoid blackmail and restore encrypted files is to contact a specialized company.

It is the case with HelpRansomware, a leading company in cybersecurity, ransomware removal, and decryption.
