Recorded Future and Shodan released Malware Hunter, a specialized crawler for security researchers that explores the Internet to find computers acting as remote access trojan (RAT) command and control centers.

Malware Hunter unearths computers hosting RAT controller software that remotely controls malware-infected computers and instructs them to execute malicious activities such as recording audio, video, and keystrokes on a victim’s machine. Using command and control servers, attackers can launch widescale attacks on thousands of computers at once and hide their tracks.
