Why these techniques?

Vulnerability in Picklescan allows evasion of detection for malicious pickle payloads that execute Python code (T1059.006) to steal credentials from local files (T1081), apply non-standard encoding for DNS-safety (T1132.002), and exfiltrate via DNS using ssl.get_server_certificate over an unencrypted non-C2 protocol (T1048.003).

SI-8 Spam Protection
addresses: CWE-184

Spam filters rely on evolving blacklists, signatures, and heuristics of disallowed message patterns; keeping them updated per the control directly mitigates incomplete disallowed-input lists.
