XORsearch: Searching With Regexes, (Mon, Apr 7th)

This post explains a practical method to use regex with XORsearch by first extracting all ASCII strings (-S) and then applying a regex via re-search.py (e.g., for IPv4), demonstrated on a Cobalt Strike beacon to reveal an IP address, URL path, XOR encoding, and key 0x0D; it also shows using -n for surrounding context and notes an upcoming YARA-based approach pending a Python version of XORsearch.
