Monitoring Dark Web Sources
When to Use
Use this skill when:
- Establishing continuous monitoring for organizational domain names, executive names, and product brands on dark web forums
- Investigating a reported data breach claim found on a ransomware leak site or paste site
- Enriching an incident investigation with context about stolen credentials or planned attacks
Do not use this skill without proper operational security measures — dark web browsing without isolation exposes analyst infrastructure to adversary counter-intelligence.
Prerequisites
- Commercial dark web monitoring service (Recorded Future, Flashpoint, Intel 471, or Cybersixgill)
- Isolated operational environment: Whonix OS or Tails OS running in a VM with no persistent storage
- Keyword watchlist: organization domain, key executive names, product names, IP ranges, known credentials
- Legal guidance confirming passive monitoring is authorized in your jurisdiction
Workflow
Step 1: Establish Keyword Monitoring via Commercial Services
Configure dark web monitoring keywords in your CTI platform (e.g., Recorded Future Exposure module):
- Domain variations:
company.com, @company.com, company[dot]com
- Executive names: CEO, CISO, CFO full names
- Product/brand names
- Internal codenames or project names (if suspected breach scope is broad)
- Known email domains for credential monitoring
Most commercial services (Flashpoint, Intel 471, Cybersixgill) crawl forums like XSS, Exploit[.]in, BreachForums, and Russian-language cybercriminal communities without analyst exposure.
Step 2: Manual Investigation with Operational Security
For investigations requiring direct dark web access:
Environment setup:
- Use a dedicated physical machine or air-gapped VM (Whonix + VirtualBox)
- Connect via Tor Browser only — never via standard browser
- Use a cover identity with no links to organization
- Never log in with real credentials to any dark web site
- Document all sessions in investigation log with timestamps
Paste site monitoring (clearnet-accessible, no Tor required):
