What it detects

This rule detects a command line that changes the console code page with chcp and then runs nltest for domain trust enumeration. TA866 Asylum Ambuscade used cmd.exe with chcp 65001 chained to nltest DOMAIN_TRUSTS during host reconnaissance. A UTF-8 code-page switch immediately preceding domain trust enumeration is a scripted discovery pattern tied to this actor.
