Abstract
A cybersecurity server receives an executable file. The executable file is disassembled to generate assembly code of the executable file. High-entropy blocks and blocks of printable American Standard Code for Information Interchange (ASCII) characters are removed from the assembly code. Instructions of the assembly code are normalized, chunked, and merged into a data stream. The digest of the data stream is calculated using a fuzzy hashing algorithm. The similarity of the digest to a malicious digest is determined to evaluate the executable file for malware.
