Abstract
Malicious code is detected in binary data by disassembling machine language instructions of the binary data into assembly language instructions. Opcodes of the assembly language instructions are normalized and formed into groups, with each group being a subsequence of a sequence of machine language instructions of the binary data. The subsequence is delimited by a predetermined machine language instruction. Locality-sensitive hashes are calculated for each group and compared to locality-sensitive hashes of known malicious machine language instructions to detect malicious code in the binary data.
