Query MalwareBazaar for file hash (MD5/SHA1/SHA256): malware family, file type, size, tags, first/last seen, download count. Use to check if file hash is known malware; use ioc_lookup for auto-detection of all IOC types. Companion malware-investigation tools: ioc_lookup (multi-source: ThreatFox + Feodo Tracker + URLhaus), threat_intel (domain-level URLhaus check), exploit_lookup (link a known CVE to PoC code if the hash maps to an exploit binary). Free: 30/hr, Pro: 500/hr. Returns {found, malware_family, file_type, file_size, tags, first_seen, last_seen, signature}.
