Dark web

Část internetu, která není indexována vyhledávači a pro přístup k ní je třeba speciální software nebo autorizace, často se používá k nelegálním nebo nezákonným činnostem.

 


 

What is dark web?

Dark web is a part of the internet that’s intentionally hidden and cannot be accessed via standard search engines. Access requires special software—most commonly the Tor browser. Websites on the dark web are anonymous and often encrypted, making it a common space for illicit activity. For companies, the key concern is that stolen login credentials, customer databases, and sensitive documents often end up for sale or on public “dump” forums here.

 

How dark web appears in practice

Examples of real-world scenarios:

  • Employee login details compromised via phishing appear on dark web marketplaces.
  • After a ransomware attack, attackers leak company files on a dark web forum to pressure payment.
  • Criminals offer access to a company’s internal network for sale on dark web forums.
  • Hackers exchange detailed guides for exploiting specific enterprise software.
  • A company discovers that its brand is being used in fraudulent dark web campaigns.

 

These examples show that dark web threats are often early warning signs of a much larger breach. Monitoring this space can help detect compromises before they escalate.

 

Dark web surface web and deep web – What’s the difference?

  • Surface web
    The public web—content accessible through Google, Bing, Seznam, etc.
  • Deep web
    Content not indexed by search engines, such as internal databases, intranets, and password-protected systems. Completely legal and widely used.
  • Dark web
    A hidden part of the deep web, accessible only with specific tools (e.g., Tor). Typically anonymous and often linked to illegal activity.

 

The deep web is neutral, but the dark web is high-risk. For businesses, it's critical to know whether their data or identity is exposed in these hidden areas.

 

How to handle dark web as a company

Recommended steps:

  • Monitor for leaks of company data—including credentials, internal documents, and your domain name—on dark web platforms.
  • Use specialized tools (e.g., EDR or SOC solutions with dark web monitoring capabilities).
  • Implement multi-factor authentication to prevent misuse of leaked passwords.
  • Educate employees about phishing, password security, and social engineering.
  • Review publicly available information about your company regularly—not just through standard search engines.
  • Act quickly if a breach is detected—change credentials, notify affected parties, and consider legal steps.

 

Many companies react only once damage is visible. But threats often surface first on the dark web. You don’t need to visit it daily—but you do need to ensure your company isn’t silently exposed there.
