Abstract

In an example, a detection engine identifies potential malware objects according to behavior. In order to circumvent blacklists and fingerprint-based detection, a malware server may frequently change domain names, and change the fingerprints of distributed malware agents. A malware agent may perform only an initial DNS lookup, and thereafter communicate with the malware command-and-control server via 'naked' HTTP packets using the raw IP address of the server. The detection engine identifies malware agents by this behavior. In one example, if an executable object makes repeated HTTP requests to an address after the DNS lookup 'time to live' has expired, the object may be flagged as potential malware.
