Skill UI

This skill provides a structured approach to systematically identify security threats by applying the STRIDE methodology (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege). It is crucial for conducting thorough threat modeling sessions, analyzing system architectures, reviewing security design decisions, and creating robust security documentation for compliance and auditing purposes.

Audits a domain’s email authentication by querying SPF, DKIM, and DMARC DNS records using dnspython, validating syntax/counts, flagging common spoofing risks, and producing remediation guidance.

This tool simulates advanced security testing to identify vulnerabilities in API rate limiting. It bypasses throttling controls by manipulating request headers (like X-Forwarded-For spoofing), varying source IP addresses, and manipulating endpoint paths. Essential for assessing API resilience against brute-force attacks, credential stuffing, and resource exhaustion, aligning with OWASP API Security guidelines.

A comprehensive tool designed to simulate advanced Layer 2 network attacks, including VLAN hopping, switch spoofing (DTP attacks), and double tagging. This skill is critical for authorized penetration testing environments to validate the effectiveness of VLAN segmentation, analyze 802.1Q trunking robustness, and ensure switch port security configurations are correctly implemented against Layer 2 bypass attacks.

A comprehensive playbook for bypassing 401/403 Forbidden errors. Covers advanced techniques like path normalization tricks (encoding, traversal), HTTP method tampering, IP spoofing headers, and protocol downgrade attacks. Essential knowledge for penetration testing and security auditing.

A comprehensive playbook for security testing APIs relying on JWT, bearer tokens, or API keys. It covers token validation weaknesses (e.g., 'alg:none', RS256 confusion), claim misuse, header spoofing, rate limit bypass, and mass assignment vulnerabilities. Ideal for penetration testers assessing authentication boundaries.

This expert playbook covers advanced techniques for email header injection and authentication bypass. It details exploiting CRLF vulnerabilities in SMTP headers (e.g., BCC/CC injection, body control) and bypassing modern email security standards like SPF, DKIM, and DMARC. Essential for penetration testing of contact forms, email APIs, and password reset workflows.

This comprehensive playbook details advanced techniques for exploiting Layer 2 and Layer 3 network protocols. It covers attacks such as ARP spoofing, LLMNR/mDNS poisoning, WPAD abuse, DHCPv6 takeover, VLAN hopping, and STP manipulation. Designed for penetration testers, it facilitates MitM positioning, credential harvesting (NTLM relay), and robust network environment exploitation.

This skill generates a comprehensive, structured threat model for any given service or feature using the STRIDE framework. It guides users through identifying critical assets, defining trust boundaries, enumerating specific threats (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege), assessing risk, and proposing concrete mitigation controls. Ideal for security design reviews and documentation.

This skill provides a comprehensive solution for monitoring brand impersonation attacks across multiple digital vectors. It systematically scans domains, social media platforms, mobile app stores, and the dark web to detect phishing campaigns, typosquatting, and unauthorized brand usage. It is essential for security teams conducting proactive threat intelligence gathering and vulnerability assessments to safeguard brand integrity.
