Checkmate Ransomware
Summary
The Checkmate Ransomware threat possesses the ability to completely lock its victims out of their own data. If executed successfully on the breached devices, the malware will proceed to target a wide range of file types, including any documents, PDFs, archives, databases, photos and more. Typically, ransomware threats utilize military-grade cryptographic algorithms to ensure that all locked files will be virtually impossible to restore without knowing the proper decryption keys. The instructions that the operators of the Checkmate Ransomware leave for their victims will be delivered to the infected systems as a text file named !CHECKMATE_DECRYPTION_README.txt. Before making the payment, victims of the threat are supposedly allowed to send up to 3 files that are no bigger than 15MB to the attackers.
