For example: RESTORE_INFO-4ABFA0EF.txt\n In addition, SynAck also appends its own extension at the end of all files it encrypted. This file extensions format is ten random alpha characters for each file. For example: test.jpg.XbMiJQiuoh. Experts believe the group behind SynAck uses RDP brute-force attacks to access remote computers and manually download and install the ransomware.",
