testing-for-system-prompt-leakage

by Cybersecurity Skills

Extracts LLM system prompts using direct requests, jailbreak/instruction-override framing, translation/encoding tricks, and few-shot replay, combining manual payloads with automated garak and Promptfoo scanners to surface embedded secrets, routing logic, and policy leakage (OWASP LLM07:2025). Use during LLM application red-team engagements or when validating that no credentials or authorization logic live in the system prompt.

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 performing-dynamic-analysis-of-android-appPerforms runtime dynamic analysis of Android applications using Frida, Objection, and Android Debug Bridge to observe application behavior during execution, intercept function calls, modify runtime values, and identify vulnerabilities that static analysis misses. Use when testing Android apps for runtime security flaws, hooking sensitive methods, bypassing client-side protections, or analyzing obfuscated applications. Activates for requests involving Android dynamic analysis, runtime hooking, Frida Android instrumentation, or live app behavior analysis.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 performing-network-forensics-with-wiresharkCapture and analyze network traffic using Wireshark and tshark to reconstruct network events from PCAP/PCAPNG files, extract transferred files and credentials, and identify command-and-control communications. Use when analyzing captured traffic from a security incident, reconstructing data exfiltration, or finding network indicators of compromise during malware analysis.2 installs monitoring-darkweb-sourcesMonitors dark web forums, marketplaces, paste sites, and ransomware leak sites for mentions of organizational assets, leaked credentials, threatened attacks, and threat actor communications to provide early warning intelligence. Use when establishing dark web monitoring coverage, investigating specific data breach claims, or enriching incident investigations with dark web context. Activates for requests involving dark web OSINT, leak site monitoring, credential exposure, Recorded Future dark web, or Tor hidden service intelligence.2 installs
