TL;DR

This repository provides a comprehensive set of cybersecurity skills designed to equip AI agents with the technical knowledge required for authorized security engagements. It focuses on translating complex offensive and defensive maneuvers into a structured format that agents can execute reliably.

The collection covers critical security activities including credential access, privilege escalation, and the decryption of Windows DPAPI-protected secrets. It is built for automation builders who need to integrate specific red-team methodologies into AI-driven security workflows.

Suggested first task

Triage a suspected business-email-compromise message

Uses detecting-business-email-compromise

  • Suspected email headers and message body
  • Sender and recipient roles
  • Normal communication patterns
  • Payment-change and approval process
  • Relevant email or SIEM log excerpts, if available
Use the detecting-business-email-compromise skill to perform an initial defensive triage of this suspected executive or vendor impersonation email: [paste the email headers and message body]. Use this organizational context: [describe the sender, recipient, normal communication pattern, and payment-change approval process]. Identify relevant BEC indicators, list the evidence that should be verified in email or SIEM logs, and recommend immediate non-destructive validation steps. Do not initiate payments, contact external parties, or modify production controls.
Suggested first task

Review an API-gateway log sample for abuse

Uses analyzing-api-gateway-access-logs

  • Path to or excerpt from authorized API-gateway access logs
  • Log source and format
  • Field definitions for user, endpoint, resource ID, status code, source IP, headers, and HTTP method where available
Use the analyzing-api-gateway-access-logs skill to review this authorized log sample: [path to or pasted excerpt from AWS API Gateway, Kong, or Nginx access logs]. First describe the available fields and data limitations, then look for a small set of supported indicators: sequential resource-ID access consistent with BOLA/IDOR, 401 surges consistent with credential scanning, injection attempts, rate-limit bypass patterns, and unusual write methods on read-only endpoints. Return a concise prioritized findings summary with supporting log evidence; do not change gateway configuration.
Suggested first task

Create an initial overview of a malware PCAP

Uses analyzing-network-traffic-of-malware

  • Path to an authorized malware PCAP
  • Confirmation that Wireshark 4.x and tshark are installed
  • Incident or sandbox time window and known internal address ranges, if available
Use the analyzing-network-traffic-of-malware skill to create an initial overview of the authorized PCAP at [path/to/malware.pcap]. Assume Wireshark 4.x and tshark are installed; state if another documented prerequisite is needed for any proposed step. Summarize capture statistics, protocol hierarchy, top IP endpoints, TCP conversations, and DNS activity, then identify a short list of traffic requiring deeper C2, exfiltration, DGA, tunneling, or fast-flux investigation. Preserve the original capture and do not contact observed external infrastructure.
