Abstract
A method of generating a similarity hash for an executable includes extracting a plurality of characteristics for one or more classes in the executable, and transforming the plurality of characteristics into a set of one or more class fingerprint strings corresponding to the one or more classes. The set of class fingerprint strings is transformed into a hash string using minwise hashing, such that a difference between hash strings for different executables is representative of the degree of difference between the executables. The hash of a target executable is compared with hashes of known malicious executables to determine whether the target executable is likely malicious.
