This rule detects Python scripts that use base64 decoding and execution, specifically looking for the 'import base64' statement appearing early in the file, followed by 'exec(base64.b64decode(' and ').decode('utf-8'))'. This pattern is indicative of a common method for obfuscating and executing malicious Python payloads, often seen in malware like KongTuke.
