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%.
