A new ransomware family has been found targeting Linux-based Network Attached Storage (NAS) devices made by Taiwan-based QNAP Systems. The new malware is written in the Go programming language and encrypts files with targeted extensions using AES encryption. If a compromised NAS device is located in Belarus, Ukraine, or Russia, the ransomware terminates the file encryption process and exits without doing any harm to the files. Researchers at Intezer and Anomali took advantage of a logical weakness in the ransomware infrastructure that allowed them to stop this malware from infecting new victims temporarily.
