Malware is primarily distributed through malicious attachments and links in spam emails/messages, online scams, drive-by (stealthy and deceptive) downloads, dubious download sources (e.g., unofficial and freeware websites, P2P sharing networks, etc.), illegal program activation tools ("cracks"), and fake updates.

When an infectious file is executed, run, or otherwise opened - the infection chain is initiated.

Malware (ransomware included) is proliferated using phishing and social engineering techniques. However, they have two significant differences in-between - the cryptographic algorithms they use ( symmetric or asymmetric) and the ransom size. These malicious programs operate by encrypting data and demanding ransoms for the decryption. We have analyzed thousands of ransomware-type programs Watch, BrutusptCrypt, and PLAY are merely a few examples. Therefore, we highly recommend keeping backups in multiple separate locations (e.g., unplugged storage devices, remote servers, etc.) - to avoid permanent data loss. The only solution is recovering them from a backup (if available). Unfortunately, removal will not restore already affected files. To prevent Checkmate ransomware from encrypting more data, it must be eliminated from the operating system. Hence, we strongly advise against doing so, as data recovery is not guaranteed, and paying supports this illegal activity. Prior to paying, victims can test decryption by sending the criminals up to three files that do not exceed 15MB.īased on our extensive experience researching ransomware infections, we can conclude that decryption is usually impossible without the cyber criminals' interference.įurthermore, despite meeting the ransom demands - victims frequently do not receive the promised decryption tools. Victims are informed that they must pay 15000 USD in Bitcoin cryptocurrency to decrypt their data. The ransom note states that the inaccessible files have been encrypted and backups deleted.

Once the encryption process was completed, this ransomware created a ransom-demanding message named " !CHECKMATE_DECRYPTION_README.txt" on the desktop. For example, a file originally titled " 1.jpg" appeared as " 1.jpg.checkmate", " 2.png" as " 2.png.checkmate", and so on. It is designed to encrypt data and demand payment for the decryption.Īfter we executed a sample of Checkmate on our test machine, it encrypted files and appended their filenames with a ". Checkmate is the name of a malicious program classified as ransomware.
