What it detects

This rule detects the command interpreter executing a batch file whose name is a single character, an obfuscation and staging pattern observed in Salt Typhoon intrusions. One-letter script names are an anomalous convention rarely used by legitimate software, so single-character batch execution is a heuristic indicator of scripted attacker tooling.
