Which of the following vulnerability scanner scans from CGI, IDA, Unicode, and Nimda vulnerabilities?

Hackbot targets web server attack surfaces including CGI script flaws, IIS IDA/Unicode traversal bugs, and Nimda worm entry points, making it the tool that matches all four listed vulnerability types.

SARA (Security Auditor's Research Assistant) is a network-level vulnerability scanner derived from SATAN and does not specialize in CGI, IDA, Unicode, or Nimda web-specific checks.

Nessus is a broad-spectrum vulnerability scanner covering many categories but is not specifically identified as the dedicated tool for the CGI, IDA, Unicode, and Nimda combination described.

Cgichk focuses narrowly on CGI script vulnerabilities only and does not cover IDA, Unicode traversal, or Nimda attack vectors.
