GenRex: Generator of Regular Expressions

GenRex is a unique tool for detecting similarities in artifacts
(extracted data) from executable files and for generating regular
expressions from them. It implements an advanced algorithm to create
regular expressions, improves state-of-the-art algorithms, and includes
domain-specific optimizations and pattern detections for optimal
results.

Generated regular expressions can be used for malware
detections, for example, with YARA or any other pattern-matching tool. We also
tested GenRex on publicly available behavioral reports and achieved a
high True Positive Rate of 92.34% and a low False Positive Rate of
0.01%.
