Tactics, Techniques, and Procedures

  • He identified peripheral web servers via Google and Linkedin searches
  • Used known WordPress flaws and custom bugs to compromise PHP sites
  • Linux authentication mechanisms were altered to capture credentials
  • Nmap was used to identify exposed network services internally
  • Corporate Wikis revealed administrative workflows and VPN details
  • Ticketing, bug tracking, and version control systems provided secrets (e.g. cryptographic keys, seeds, hashes, credentials, and source code)
  • Cookies from weak non-production instances (e.g. staging) were valid in production as cryptographic materials were the same — bypassing 2FA
  • Client certificates (exposed by email, ticketing, or lifted from filesystems) were combined with known credentials to access corporate VPNs
  • Engineering credentials were used to commit backdoors to version control which were self-approved and later deployed into production
