QNAP Systems is warning about Checkmate, a new piece of ransomware targeting users of its network-attached storage (NAS) appliances.
“Preliminary investigation indicates that Checkmate attacks via SMB services exposed to the internet, and employs a dictionary attack to break accounts with weak passwords,” the company says.
“Once the attacker successfully logs in to a device, they encrypt data in shared folders and leave a ransom note with the file name ‘!CHECKMATE_DECRYPTION_README’ in each folder.”
