Sicher Hash Reputation Lookup
x402
Sicher Hash Reputation Lookup is a paid API for AI agents from sicher.halowerk.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-10).
Queries abuse.ch MalwareBazaar, ThreatFox, and URLhaus to determine whether a file hash (MD5, SHA-1, or SHA-256) is associated with known malware, returning a consolidated known-malicious or unknown verdict.

How this service works
Queries three abuse.ch metadata services for an MD5, SHA-1 or SHA-256 value. It reports known malware metadata, associated ThreatFox indicators, and URLhaus payload provenance, then derives a conservative known-malicious or unknown verdict. No endpoint for sample retrieval is called and no binary is downloaded. A missing record means unknown to these sources, not proven benign. VirusTotal is deliberately not used because its public terms do not permit redistribution in this paid product.
Output
Returns malware metadata from MalwareBazaar (file type, tags, first seen), ThreatFox indicator associations (threat actor, malware family, confidence), and URLhaus payload provenance (URLs that distributed the file), plus a synthesized verdict of 'known-malicious' or 'unknown'. A missing record means the hash is unknown to these sources, not proven benign.
Example use cases
Malware triage during incident response
“We found a suspicious file on a compromised host with SHA-256 hash 3395856ce81f2b7382dee72602f798b642f14d0. Check if it's known malware — pull MalwareBazaar, ThreatFox, and URLhaus metadata and tell me the verdict.”
CI/CD pipeline artifact integrity check
“Before we deploy, check this build artifact: its MD5 is d41d8cd98f00b204e9800998ecf8427e. Has it shown up in any abuse.ch malware databases? I need to know if it's flagged as malicious or just unknown.”
Threat intel enrichment for SOC alert
“We got an alert with a file hash — SHA-1 is da39a3ee5e6b4b0d3255bfef95601890afd80709. Can you enrich this with abuse.ch threat intelligence and tell me whether ThreatFox or URLhaus have any associated indicators?”
Technical details
Endpoint
POSThttps://sicher.halowerk.com/v1/hash-reputation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a privacy-respecting, redistribution-safe file hash reputation check that aggregates MalwareBazaar, ThreatFox, and URLhaus without VirusTotal (whose public terms prohibit redistribution in commercial products). Ideal for SOC automation, CI/CD pipelines, and threat enrichment workflows where you want abuse.ch-specific intelligence without downloading binaries or triggering sample retrieval.
Side effects
- Hash not found in any abuse.ch source — returns 'unknown' verdict, not an error
- Invalid hash format (wrong length or non-hex characters) — returns validation error
- Upstream abuse.ch API unavailable — service may return 503 or timeout
- Ambiguous verdict when sources disagree — conservative approach defaults to known-malicious if any source flags it
