detecting-shadow-api-endpoints

by Cybersecurity Skills

Discover and inventory shadow API endpoints that operate outside documented OpenAPI/Swagger specs, using traffic analysis against API gateways (Kong, AWS API Gateway, Envoy), cloud configuration scanning, and source code repository mining for undocumented routes. Use when assessing API attack surface, auditing for forgotten test environments or deprecated API versions still running, or building an API registration governance policy.

exploiting-insecure-deserializationIdentifying and exploiting insecure deserialization vulnerabilities in Java, PHP, Python, and .NET applications to achieve remote code execution during authorized penetration tests.4 installs performing-osint-with-spiderfootAutomate OSINT collection with the SpiderFoot REST API and CLI (sf.py/spiderfoot-cli) across 200+ modules, selecting scan modes (footprint, investigate, passive) and parsing results for domains, IPs, emails, leaked credentials, and DNS records into a target intelligence profile. Use when mapping an organization's attack surface or profiling a target for threat intelligence.3 installs exploiting-vulnerabilities-with-metasploit-frameworkUses the Metasploit Framework (msfconsole and its exploit, auxiliary, and post-exploitation modules) to validate that identified CVEs and vulnerabilities are actually exploitable, gather post-exploitation evidence, and confirm patch remediation. Use when performing vulnerability management validation, penetration testing, or post-patch verification and you need to prove real-world exploitability rather than rely on a scanner score alone.2 installs performing-ai-driven-osint-correlationUse AI/LLM-based reasoning with Sherlock, theHarvester, and SpiderFoot to correlate OSINT findings—usernames, emails, social profiles, domain records, breach databases, and dark-web mentions—into unified, confidence-scored intelligence profiles with link analysis. Use when raw OSINT data from multiple sources needs merging into one target profile or resolving identity linkage across platforms.2 installs detecting-rootkit-activityDetects rootkit presence on compromised systems by identifying hidden processes, hooked system calls, modified kernel structures, and covert network connections using Volatility memory forensics, cross-view detection, and tools like GMER, rkhunter, chkrootkit, and RootkitRevealer. Use when standard tools (Task Manager, netstat, AV/EDR) show nothing abnormal but compromise is suspected.2 installs analyzing-ios-app-security-with-objectionRuntime iOS app security testing with Objection (Frida): inspect keychain and filesystem data, explore app internals at runtime, and validate/bypass client-side protections during authorized mobile assessments.2 installs
