Coldlock- Ransomware

Multiple entities in Taiwan were targeted with the ColdLock ransomware which focuses on encrypting databases and email servers.

AES in CBC mode is used for encryption and the malware drops the ransom note in various locations including %Desktop%, %System Root%, and %User Startup%.
