How this service works
Looks up a file hash (SHA-256, SHA-1 or MD5) in abuse.ch MalwareBazaar: whether the sample is known, its other hashes, file name, type, size, signature (malware family), first/last seen, reporter, origin country, delivery method, tags, download count and code-signing info. Metadata only; the sample itself is never downloaded.
Output
Returns metadata about the matching malware sample from MalwareBazaar: all hash variants (SHA-256, SHA-1, MD5), file name, file type, file size, malware family/signature, first seen and last seen timestamps, reporter, origin country, delivery method, associated tags, download count, and code-signing information. The actual file binary is never returned.
Example use cases
Malware triage for suspicious download
“I found a suspicious executable on one of our servers — its SHA-256 is 275a021bbfb6489e54d471899f7db9d1663fc695ec2fe2a2c4538aabf651fd0f. Can you look it up in MalwareBazaar and tell me the malware family, delivery method, and when it was first reported?”
Incident response enrichment
“We just got an alert with an MD5 hash of 44d88612fea8a8f36de82e1278abb02f. Can you pull everything MalwareBazaar knows about it — origin country, reporter, tags, any code-signing info?”
Threat intel feed validation
“Our threat feed flagged a SHA-1 hash of da39a3ee5e6b4b0d3255bfef95601890afd80709 as malicious. Can you verify it against MalwareBazaar and confirm whether it's a known sample, what type of file it is, and what malware family it belongs to?”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/security/malbazaar-samples?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, structured malware metadata for a specific file hash without downloading the sample. It is ideal for triage, incident response enrichment, and threat intelligence workflows where you already have a hash and want to check against the community-maintained MalwareBazaar database. Prefer this over general VirusTotal-style endpoints when the primary need is abuse.ch community data including reporter, delivery method, and origin country attribution.
Side effects
- Hash not found in MalwareBazaar — sample is unknown or clean
- Invalid hash format (wrong length or non-hex characters) — request rejected
- MalwareBazaar API unavailable — upstream timeout or outage
- Malformed hash parameter — missing or empty 'hash' query param returns error
- Rate limiting or payment failure for the $0.002 per-call fee
