How this service works
Searches abuse.ch ThreatFox for indicators of compromise matching a term (IP, IP:port, domain, URL or file hash): IOC, type, malware family, threat type, confidence, first/last seen, reporter, tags and Malpedia link. Optional exact match and a first-seen window in days.
Output
Returns a list of matching IOC records from ThreatFox, each containing: the IOC value and type (e.g. ip:port, domain, url, hash), associated malware family name, threat type (e.g. botnet_cc, payload_delivery), confidence level (0–100), first and last seen timestamps, the reporter's alias, any associated tags, and a Malpedia link for further malware research context.
Example use cases
Triage suspicious IP from firewall logs
“I've got an IP address 45.142.212.100 showing up repeatedly in our firewall logs — can you search ThreatFox to see if it's a known malicious indicator, and tell me what malware family and threat type it's associated with?”
Validate file hash before executing
“Before I run this file, can you check ThreatFox for the SHA256 hash a3f1c2d9e7b4056f8a2d3e1c9b7f4056a3f1c2d9e7b4056f8a2d3e1c9b7f4056 and tell me if it's been flagged as malware, including the family and confidence score?”
Investigate phishing domain threat intel
“We received a phishing report mentioning the domain evilpayments-secure.com — please search ThreatFox for it with an exact match and tell me everything: IOC type, malware family, reporter, tags, and when it was first and last seen.”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/security/threatfox-iocs?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, curated threat intelligence from abuse.ch ThreatFox specifically — particularly for correlating IPs, domains, URLs, or file hashes against a community-reported malware IOC database with confidence scoring and Malpedia links. Prefer it over generic WHOIS or IP-reputation checks when you need malware family attribution, threat type classification, or reporter provenance. Complements the sibling URLhaus host-check endpoint (which focuses on active malware distribution hosts) by providing broader IOC coverage across multiple threat types.
Side effects
- No results returned if the indicator has never been reported to ThreatFox
- Partial matches may return unrelated IOCs if exact=false and the term is short or generic
- days parameter out of range (not 1–365) may cause an error or be ignored
- Network timeout if the ThreatFox upstream API is slow or unavailable
- Malformed input (e.g. invalid hash format or non-ASCII domain) may return an empty result or error
