Darknet Monitoring: What Circulates, What Endangers – and What to Do
Corporate data, credentials, and attack plans are traded on the darknet daily. How systematic monitoring works and what it concretely achieves.
What Is Really Traded on the Darknet
The term "darknet" often evokes dramatic associations. The reality is more sober, but no less concerning: the darknet and adjacent ecosystems – certain Telegram channels, paste sites, closed hacking forums – are primarily a marketplace for stolen data and criminal services. What is concretely traded there:
- Credential Lists: Collections from password leaks and infostealer outputs, sometimes filtered by company domain
- Network Access (Initial Access): Compromised VPN accesses, remote desktop accesses, or web shells enabling entry into corporate infrastructures
- Databases with stolen corporate or customer data
- Threat Announcements: Announcements of planned attacks, extortion threats, or publications of stolen data
- Attack Tools and Services (PhaaS, RaaS)
How Professional Darknet Monitoring Works
Professional darknet monitoring is not a web search with a special browser. It requires:
Access to Closed Sources: Many darknet forums and markets are not publicly accessible. Access requires either membership (often granted through social vetting processes) or operational HUMINT presence.
Automated Analysis: Given the data volume, manual analysis alone is insufficient. Specialized systems continuously index and analyze relevant sources for company- and sector-specific signals.
HUMINT Component: In critical cases – such as specific threat announcements or the sale of specific accesses – human analysis and possibly operational interaction is required.
Contextualization: Raw data is of little value without context. A professional analysis assesses the credibility of the source, the currency of the data, and concrete action recommendations.
What a Darknet Monitoring Alert Triggers
A concrete practical example: a mid-sized manufacturing company receives a warning that credentials for its ERP system are being offered in a closed hacking forum – apparently via an infostealer from a home office laptop of an IT employee. The warning comes before the attacker uses the access. Result: password is reset, session invalidated, affected device forensically examined. The potential attack is stopped before it begins.
This scenario is not an exception, but the norm with well-positioned monitoring.
