Abstract

See full text

Disclosed herein is a system and method for determining whether two files are similar or an unknown file contains malware or other malicious activity. The system takes a suspect file and generates a hash for the file. The hash represents segments of a file that may be compared with segments of other hashes. This hash is then compared with the hash of another file. The comparison measures the distance between the two hashes and if the two hashes are close enough to each other then the two files are consider similar to each other.
