I came across a Python library that passed the ASCII range into one of these non printable character ranges and then into a database. If someone was doing that manually with a hex table, how is that detected and mitigated?

I need to block a known threat actor already present on a system. Call it an exercise. I am interested in exploring and understanding it. This text obfuscation is a technique I discovered being used. This is a stage 3 threat model type of situation where every possible vector is in play.

This is not the theoretical, rtfm or read and trust the source situation.
