This skill provides comprehensive methods for collecting and synthesizing Open-Source Intelligence (OSINT) regarding threat actors, malicious infrastructure, and attack campaigns. It utilizes public data sources, passive reconnaissance tools (like WHOIS, Certificate Transparency), and specialized platforms (Maltego, Shodan, SpiderFoot) to map adversary context and perform pre-engagement intelligence gathering for authorized red team assessments. Emphasis is placed on passive collection techniques to ensure legality and operational security.

This guide details how to conduct comprehensive external reconnaissance using Open Source Intelligence (OSINT) techniques. It teaches testers to passively map an organization's entire digital footprint, including enumerating subdomains, discovering internet-facing infrastructure (via Shodan/Censys), identifying personnel data, and analyzing leaked credentials from public sources. Ideal for the initial phases of penetration testing or red team engagements.

Suricata is a high-performance, open-source network threat detection engine used for deep packet inspection. This skill details the deployment and configuration of Suricata in Intrusion Prevention System (IPS) mode. It covers setting up custom rules, integrating third-party rulesets (like Emerging Threats), and actively blocking malicious traffic in real time, making it essential for robust network security and compliance enforcement.

Utilize Velociraptor, an advanced open-source platform, to collect, query, and monitor forensic artifacts across diverse endpoints (Windows, Linux, macOS). This skill enables incident response teams to perform large-scale, rapid digital forensic investigations by collecting critical data such as event logs, registry entries, prefetch files, and network metadata using VQL queries.

Use RESTler to automate stateful security testing of REST APIs. It processes OpenAPI specifications to generate fuzzing grammars, allowing users to discover complex bugs, such as injection vulnerabilities, resource leaks, and unhandled exceptions (500 errors), by executing diverse sequences of API calls. Essential for robust CI/CD regression testing and proactive API security assessments.

CAPE is an open-source sandbox built for automated malware analysis, derived from Cuckoo. It provides advanced behavioral monitoring, payload dumping, and configuration extraction using over 70 parsers for known malware families (e.g., Emotet, Cobalt Strike). It captures network IOCs, dropped files, and detects anti-evasion techniques, making it ideal for security assessments and incident response workflows via its robust API.

Utilizes ScoutSuite, an open-source multi-cloud auditing tool, to perform comprehensive, agentless security posture assessments across AWS accounts. It queries various AWS APIs to enumerate all resources, identify misconfigurations (such as publicly exposed S3 buckets or weak IAM policies), and generate detailed, actionable HTML reports for compliance and security auditing.

LaZagne is an open-source post-exploitation tool utilized by red teams to harvest stored credentials from compromised endpoints. It supports Windows, Linux, and macOS, extracting passwords from browsers (Chrome, Edge), databases (MySQL, SQLite), system vaults (DPAPI, LSA), and various applications. It is crucial for privilege escalation and lateral movement during authorized security assessments.

An open-source tool based on the CIS Docker Benchmark. It systematically audits critical security aspects of Docker deployments, including host configuration, daemon settings, and container runtime. It generates a detailed compliance report (pass/fail/warn) to ensure best practices and security compliance in production environments.

This comprehensive guide outlines the end-to-end workflow for mobile device forensics, covering data acquisition and analysis for both iOS and Android platforms. It details techniques using commercial tools like Cellebrite UFED and open-source utilities (ALEAPP, iLEAPP, ADB). This methodology is critical for investigating deleted messages, call logs, location data, and application artifacts in legal or corporate investigations.

Open Source Intelligence (OSINT) is the critical first phase of red team engagements. This guide details how to systematically collect publicly available data about a target organization. It covers mapping network assets (domains, IPs), identifying personnel for social engineering, discovering credential leaks, and mapping the entire technology stack. Use this skill during authorized security assessments to build comprehensive attack surface maps and initial access strategies.

This guide details how to use GoPhish, an open-source framework, to conduct authorized phishing simulations. You will learn the complete lifecycle, from deploying the tool and configuring SMTP profiles, to creating realistic email templates and cloning secure landing pages. The skill culminates in analyzing campaign results to assess organizational security posture and improve employee resilience against social engineering attacks.
