About:
csprecon is an OSINT tool that analyzes Content Security Policy headers to uncover hidden and forgotten subdomains. By parsing CSP policies, it reveals new attack surfaces and potential targets that traditional recon methods might miss. This provides security professionals with deeper visibility into an organization's digital footprint.
|
Key Features:
- Parses Content Security Policy headers to extract domain information
- Fast and efficient Go-based implementation
- Supports multiple input sources including URLs and files
- Integrates with other reconnaissance workflows
- Provides clean, actionable output for further analysis
|
Use Cases:
- Expanding attack surface during penetration testing engagements
- Performing OSINT reconnaissance on target organizations
- Identifying forgotten or shadow IT infrastructure
- Mapping relationships between different web properties
|
Alternatives:
-
subfinder
– subfinder uses multiple passive sources, while csprecon specifically focuses on CSP header analysis as a unique data source
-
amass
– amass provides comprehensive enumeration including active scanning, whereas csprecon offers a lightweight CSP-focused approach
