Domain Reputation & Blocklists

What is Domain Reputation & Blocklists?

Checks domain against URLhaus, PhishTank, and other malware/phishing blocklists.

This vulnerability class falls under the Cryptography phase of the OWASP Testing Guide (N/A). Security engineers prioritise cryptography checks early in an assessment because weaknesses here provide a foothold that amplifies the severity of vulnerabilities found in later phases.

Security Impact

If your domain is blocklisted, browsers will warn users. This module detects reputation issues before they impact traffic.

Left undetected, domain reputation & blocklists issues can persist unnoticed for months. Continuous automated scanning ensures your team receives an alert the moment a regression or new exposure is introduced — long before an attacker discovers it through manual enumeration or automated offensive tooling.

How DygDog Detects It

DygDog cross-references open intelligence sources — breach databases, IP reputation feeds, and threat-actor TTPs — to surface contextual risk signals that pure technical scanning misses.

The Domain Reputation & Blocklists check is implemented as a passive scan module, meaning it never sends dangerous payloads or modifies application state. Scans complete in approximately 1.2 s and run continuously in the background so your security posture reflects the current state of your site — not a point-in-time snapshot.

Remediation Approach

Monitor breach databases and IP reputation feeds continuously; rotate credentials that appear in external datasets; and add threat-intelligence signals to your SIEM for proactive incident detection.

DygDog does not stop at detection. When a Domain Reputation & Blocklists finding is confirmed, the platform generates infrastructure-aware, copy-paste-ready remediation snippets using frontier AI models. Instead of generic advice you need to adapt, you receive code that targets your exact server, framework, and configuration.

Related Cryptography Checks

These checks belong to the same testing phase and are often assessed together:

• Email Authentication (SPF/DMARC)

  Validates SPF, DKIM, and DMARC DNS records for email spoofing protection.

• DNS Security (CAA/DNSSEC)

  Checks DNS CAA records for certificate authority restrictions and DNSSEC deployment status.

• API Surface Discovery

  Identifies exposed API endpoints, GraphQL introspection, Swagger/OpenAPI documentation, and API versioning.

• CVE/EPSS Threat Intelligence

  Enriches findings with NVD CVSS scores, FIRST EPSS exploit probability, and CISA KEV status.
