A new ransomware called Cr1ptT0r built for embedded systems targets network attached storage (NAS) equipment exposed to the internet to encrypt data available on it. The malware drops two plain text files on the infected devices with a ransom note. The operators offer to unlock the first file for free for free. The ransom note points the victim to the decryption service, which holds the same contact details and the steps for getting the unlock key. At the time of publishing, the malware is picked up by at least six antivirus engines.
