ReversingLabs Hashing Algorithm

Traditional hashing algorithms (e.g., MD5, SHA-1) provide an essential tool for security applications. Although commonly used for allowlisting and blocklisting, traditional hashes have significant drawbacks for detecting malware. First, a malicious file must be seen before a hash can be created so polymorphic attacks are not detectable. Second, hashes are fragile, enabling malware authors to make inconsequential changes to files to avoid detection.

ReversingLabs Hashing Algorithm (“RHA”) addresses these issues by intelligently hashing a file’s features rather than its bits. …
