hunting-for-webshell-activity

by Cybersecurity Skills

Runs a hypothesis-driven threat hunt for web shell deployment (T1505.003) on internet-facing servers by analyzing file creation in web directories, suspicious child-process spawning from web server processes, and anomalous HTTP request patterns. Use when hunting for web shells after a public-facing app compromise, when EDR/SIEM alerts fire on webserver process anomalies, or during incident response on internet-facing infrastructure.

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
