Key Updates

In Sublist3r v1.0, there were notable issues related to Virustotal integration, as reported by users on the GitHub issues page.

These issues primarily involved:

🚫 Virustotal Blocking Requests:

• Users frequently encountered problems where Virustotal was blocking the requests made by Sublist3r. This issue significantly hindered the tool's ability to fetch subdomain data from Virustotal, thereby reducing its effectiveness.

❌ API Integration Challenges:

• There were difficulties in integrating with the Virustotal API correctly, which may include problems with API keys or changes in the API itself that were not reflected in Sublist3r.

😞 User Experience:

• Due to these integration issues, users often had to resort to temporary fixes, such as skipping Virustotal during enumeration or manually commenting out related code segments. This not only affected the tool's user-friendliness but also its efficiency in subdomain enumeration.

✅ In Sublist3r v2.0:

All these specific issues have been addressed and optimized to ensure a smoother, more reliable integration with Virustotal. Additionally, the integration of ShrewdEye as a new source for subdomain enumeration adds to the tool's capabilities, enhancing its overall performance and the breadth of its attack surface. This update positions Sublist3r v2.0 as a more robust and reliable tool for subdomain discovery in security assessments and penetration testing scenarios.
