Why this verdict

Evidence and analysis

VerdictIQ AIGenerated from 23 deterministic signals

checkass[.]monster is classified as suspicious with a risk score of 67/100: ambiguous posture; signals suggest concern but lack convergent evidence. The recommended downstream action is alert_only.

The risk model observed 23 signals (including 5 core signals) across 4 taxonomy groups (Popularity & Backlink, HTTP Crawling, DNS History, and others). The strongest indicators are SSL Hostname Mismatch, Critical SSL CA Issue, Flagged by Security Vendors, plus 20 additional supporting signals. Each signal carries its own trigger evidence and direction; signal fusion drives the calibrated tier assignment.

Recommended response. Surface to analyst review or SIEM correlation. Evidence is strong enough to warrant attention but not strong enough to block without context. For active investigation, run POST /verdict with the indicator to confirm the verdict against the current state of the domain. VerdictIQ's scoring recomputes today's signals on every call.

VerdictIQ AI re-states deterministic signal evidence as natural language. The verdict itself comes from the calibrated risk model, not the AI layer. Re-runs are stable and explainable.

  • SSL Hostname MismatchcoreHTTP CrawlingIt means the SSL/TLS certificate’s Common Name (CN) or Subject Alternative Name (SAN) does not match the accessed domain.
  • Critical SSL CA IssuecoreHTTP CrawlingIt means that the SSL/TLS certificate presented by the domain failed critical validation checks.
  • Flagged by Security VendorscoreThreat IntelligenceIt means that one or more commercial security vendors, including antivirus engines, sandboxes, or threat intelligence providers, have classified or reported the domain as malicious.
  • Untrusted or Misconfigured SSL CertificatecoreHTTP CrawlingIt indicates that the domain’s SSL/TLS certificate cannot be fully trusted due to issues such as expiration, incorrect configuration, mismatched hostname, or unrecognized certificate authority.
  • Listed in Malware SourcescoreThreat IntelligenceIt means that the domain has appeared in public or open-source malware intelligence feeds.
  • Weak Popularity DomainPopularity & BacklinkIt represents a domain with limited but detectable user traffic or DNS activity.
  • Newly-Activated DomainDNS HistoryIt indicates that the domain has recently become active and started responding to DNS queries after a period of inactivity or recent registration.
  • Malicious Activity Observed During Browser InteractionHTTP CrawlingIt indicates that malicious behavior was detected only during dynamic browser interaction, such as JavaScript execution, redirects, or AJAX calls, rather than in static content.
  • Geolocation Mismatch or High-Risk RegionDNS HistoryIt indicates that the ASN shows geolocation anomalies, such as a mismatch between registry country and observed country or continent, or that it is associated with a country known for elevated abuse…
  • Non-Public DomainHTTP CrawlingIt refers to a domain that operates with restricted accessibility, its HTTP/HTTPS services are either protected, limited to specific users, or intentionally unreachable from the public internet.
  • Short-Term SSL Certificate ValidityHTTP CrawlingIt means the SSL/TLS certificate of the domain has an unusually short validity period, often lasting only days or weeks.
  • Default Web Page DetectedHTTP CrawlingIt refers to a website that displays the default or placeholder page of a known web technology, such as 'Apache Default Page' or 'Nginx Welcome Page'.
  • Newly-Issued SSL CertificateHTTP CrawlingIt indicates that the SSL certificate associated with the domain has been newly created or issued.
  • Small Allocation Abuse PatternDNS HistoryIt indicates that a small-sized IP prefix shows a concentration of malicious activity, such as repeated blacklist hits, high-risk domain density, or rapid domain churn, suggesting abuse within the…
  • Assigned IP BlockDNS HistoryIt indicates that the IP block has the RIR status 'assigned', which is commonly associated with end-user or reseller address space that frequently changes hands and exhibits higher abuse rates than…
  • Geo-ASN Country MismatchDNS HistoryThe IP's geolocation country doesn't match the ASN's registered country.
  • Current and Historical Geolocation DivergenceDNS HistoryIt indicates that the geolocation of the domain’s currently active IP addresses significantly differs from the geolocations observed in its historical IP usage, suggesting a notable shift in…
  • Limited Web Structure DetectedHTTP CrawlingIt means the domain hosts only a few subpages or internal links.
  • Private Certificate Authority (CA) Signed SSL DetectedHTTP CrawlingIt means that the SSL/TLS certificate in use was issued by a private or internal Certificate Authority rather than a globally recognized CA.
  • Paid Public NS Usage Premium ProviderDNS HistoryIt indicates that the domain is backed by a paid, reputable DNS provider rather than free or disposable nameservers.
  • Country-Level IP Geolocation CentralizationDNS HistoryIt indicates that all currently active IP addresses of a domain are geographically concentrated in a single location scope, typically within one country.
  • Observed and Registered Geolocation ConsistencyDNS HistoryIt indicates that the observed geolocation of the IP matches its registered geolocation, suggesting a stable and expected geographic placement for the infrastructure at the time of observation.
  • ASN Allocated Long Time AgoDNS HistoryIt means that the ASN was allocated many years ago and has a long operational history.
