Malware Signature Lookup — DNSBL Malware & Spam Scan
Query malware-oriented DNSBL zones for IPv4 or domain with infrastructure context flags
How to Use This Tool
- Enter a public IPv4 address or domain name in the query field.
- Domains resolve to current A record IPv4 with resolvedFrom metadata.
- Parallel DNSBL queries run against primary and extended zones.
- Listed zones tag true; malwareListHits filters spam and exploit-oriented names.
- Geolocation adds hosting, VPN, proxy, org, and country for the resolved IP.
- Review malwareListed, malwareListHits, recommendation, and lists array.
About This Tool
Incident responders and SOC analysts often search malware signature lookup when correlating indicators from sandboxes, mail gateways, or firewall logs — they need fast DNSBL-oriented answers on whether an address carries malware or spam list signatures at query time. VSPIC malware signature lookup calls the malware-ip action with your query, resolves domains to current A record IPv4 when needed, queries primary and extended DNSBL zones with emphasis on malware and spam publishers, and surfaces malwareListHits separately from general listing noise.
Results include query, ip, resolvedFrom, malwareListed boolean, listedCount, lists array with per-zone status, malwareListHits names, hosting, proxy, vpn flags, org, country, summary, and recommendation text. This page frames malware signature SEO vocabulary while the backend matches malware-ip-checker and botnet-detection — focused DNSBL malware signals without composite fraud scoring.
Common use cases
- •Check if a VPN or proxy is detected on your connection
- •Validate SSL certificates before launch
- •Scan for email addresses in known breaches
Why use VSPIC for ?
- Malware signature framing on DNSBL malwareListHits emphasis.
- Accepts IPv4 or domain with automatic DNS resolution.
- Per-list breakdown with query hostnames for delisting tickets.
- Hosting, VPN, and proxy flags explain infrastructure context.
- Plain-language summary and remediation recommendation text.
- Free instant lookup — no account required.
What malware signature lookup measures here
True malware family signature matching requires sandbox detonation, YARA rules, and endpoint telemetry. Our page provides DNSBL-oriented signature context — addresses participating in spam, exploit, or drone activity often list on community and commercial blocklists hours before traditional AV catches them.
malwareListed true means at least one malware-oriented zone returned positive at query time. Treat that as escalation signal requiring log review and endpoint inspection, not automatic guilt verdict.
malwareListHits versus listedCount
listedCount counts every DNSBL hit across all queried zones. malwareListHits narrows to zones whose names match spamhaus, dronebl, backscatter, barracuda, and blocklist patterns — the subset most correlated with malware and spam drone activity in abuse desk workflows.
An IP listed only on niche lists may show listedCount greater than zero while malwareListed stays false until a malware-oriented zone hits.
Domain input and resolvedFrom metadata
Paste hostnames from mail headers or sandbox reports when logs show domains instead of numeric IPs. resolvedFrom links original query to scanned IPv4. CDN-fronted domains resolve to edge pools whose listing status may differ from origin servers.
When you know the abusive server IP from logs, prefer direct IPv4 input to skip DNS resolution ambiguity.
Infrastructure context fields
hosting true indicates datacenter or cloud allocation — malware activity clusters on compromised shared hosting but legitimate APIs also egress from hosting networks. vpn and proxy true suggest anonymizer paths common in fraud rings but also used by privacy-conscious users.
Combine org and country with listing data. Bulletproof hosting ASNs with multiple malwareListHits deserve urgent abuse desk review.
Relationship to malware-ip-checker
Both pages call action malware-ip with identical JSON shape. malware-ip-checker uses malware IP SEO vocabulary; malware-signature-lookup targets operators searching malware signature terminology from threat feeds and sandbox export workflows.
API consumers use malware-ip with query parameter interchangeably.
Incident response workflow
Run after IDS alerts reference unknown egress, when mail bounces cite blocklist rejection, and before allowing new vendor VPN endpoints through firewall rules. Export JSON with malwareListHits names for provider abuse tickets.
Schedule periodic checks on mail server egress and web origin addresses — listings appear within hours of compromise.
Delisting and remediation
recommendation text nudges listed addresses toward patching, root-cause fix, and formal delisting. Each list maintainer publishes different removal procedures — document zone names in tickets.
Delisting takes time — rescoring after removal requires rerun. Multiple zones may need separate delisting workflows.
API action malware-ip
GET /ip-tools/api/extended?action=malware-ip&query=8.8.8.8. Parse malwareListed, malwareListHits, lists, hosting, vpn, proxy. Cache briefly — DNSBL status changes hourly during campaigns.
Rate limits protect upstream DNS resolvers — stagger bulk internal scans.
Legal and responsible use
Lookup only IPs and domains you own or are authorized to investigate. DNSBL listing is an abuse signal, not legal proof of criminal activity.
We query public DNSBL zones at lookup time and do not permanently store your searches.
Important notes & limitations
- DNSBL listing is not proof of active malware infection — investigate logs.
- Clean result does not guarantee a host is uncompromised.
- Point-in-time DNS answers — status changes during campaigns.
- Does not include composite fraudScore — use ip-reputation-checker for that.
- IPv6-only hosts need an IPv4 A record or direct IPv4 input.
