Locky is a new cyberthreat that has received a lot of attention in security circles over the last few months because it has been unusually successful. Locky is advanced ransomware that encrypts a person’s files and holds them for ransom. It uses a number of different technologies to avoid being detected or blocked and takes great care to hide its path back to the attackers. The code is obfuscated to avoid detection by antivirus and malware software. The blackmailers communicate through TOR and only accept Bitcoin as payment, making it nearly impossible to discover who they are.
