Guide Shows How to Hunt Exposed C2 Panels Using Web Fingerprints

· Original article ↗

Summary

A practical guide demonstrates how defenders can identify exposed Supershell, HookBot, Chaos RAT, UnamWebPanel, Metasploit, and Mythic panels using URL paths, page titles, favicon hashes, and other web artifacts, then block and report exposed instances.

Key points

  • The guide uses Hunt.io datasets and HuntSQL to search web telemetry, URL indexes, and crawled page artifacts for exposed panels.
  • Example fingerprints include Supershell’s login path, HookBot’s page title and favicon hash, and Chaos RAT’s HTML hash and GitHub reference.
  • It also gives search patterns for UnamWebPanel, Metasploit, and Mythic dashboards.
  • Exposed panels can let operators manage compromised hosts, issue commands, and handle stolen data or payloads.
  • Recommended responses include adding fingerprints to monitoring and blocking rules, recording passive evidence, and reporting findings to providers or a CERT.
  • The guide advises against logging in to or interacting with discovered panels.

Defense Focus
Identify and track exposed command-and-control panels using web fingerprints and passive internet-scan telemetry, then block or report confirmed exposure.
Detection Methods
  • Search URL paths such as /supershell/login/ and panel-specific page titles, including Supershell, HOOKBOT PANEL, Unam Web Panel, Metasploit, and Mythic.
  • Pivot on the HookBot favicon MD5 and the Chaos RAT HTML-body SHA-256 hash.
  • Use redirect paths such as /login and /new/login together with page titles to improve panel identification.
  • Search panel HTML for the Chaos RAT repository reference and correlate related pages.
  • Validate candidates using page snapshots, scripts, favicons, embedded resources, response patterns, and hosting metadata.
Data Sources
  • HTTP response headers and page content (httpv2)
  • URL index (urlx)
  • Crawler page snapshots and artifacts, including scripts, favicons, and embedded resources (crawler)
  • TLS certificates and hosting metadata
Rule Types
  • HuntSQL queries filtering URL paths, HTML titles, redirects, favicon hashes, HTML-body hashes, and repository references
  • IDS/IPS signatures
  • SIEM rules
  • WAF and firewall rules
  • Monitoring alerts and blocklists
Platforms
  • HuntSQL
Defensive Actions
  • Block confirmed exposed panels at the network edge using WAF or firewall rules.
  • Add panel fingerprints to IDS/IPS signatures, SIEM rules, monitoring pipelines, and blocklists.
  • Enrich findings with ASN or IP metadata and monitor relevant callback activity.
  • Record passive evidence, including the exact timestamp and URL; do not attempt to log in or interact with an exposed panel.
  • Report findings to the hosting provider or relevant CERT.
  • Share indicators through controlled channels or redact sensitive details to avoid enabling abuse.
  • For Chaos RAT, monitor suspicious crontab entries, scheduled tasks, and abnormal reverse-shell activity; favor behavioral detection over static signatures.
