Guides writing high-quality YARA-X detection rules for malware hunting, covering naming conventions, string selection, performance tuning, migrations from legacy YARA, and reducing false positives when authoring, reviewing, or debugging signatures.

Yara Authoring helps security teams write precise YARA rules for threat detection and malware hunting by guiding string/tag management and metadata handling so signature creation keeps pace with investigations.

This skill enables deep analysis of malware families using the Malpedia API. It allows users to retrieve canonical aliases, associated threat actors, and YARA detection rules, and map complex relationships like loader-payload chains. Ideal for threat intelligence research, incident response, and building automated detection signatures.

Analyzes behavioral reports from security sandboxes (Cuckoo, AnyRun) to detect advanced anti-analysis and evasion techniques. It specifically identifies indicators such as timing checks, hypervisor artifact queries, user interaction patterns, and environment fingerprinting. This tool is essential for threat hunting, enhancing detection rules, and conducting deep malware triage.

A comprehensive, multi-stage framework for responding to confirmed or suspected malware infections across an enterprise. This guide covers the entire incident lifecycle: detection, scoping, containment, deep analysis (mapping to MITRE ATT&CK), thorough eradication, and system recovery, ensuring all steps are documented for resilience and compliance.

This skill provides comprehensive guidance and detection rules for identifying fileless malware, in-memory attacks, and living-off-the-land techniques. It covers detecting PowerShell exploitation, reflective DLL injection, WMI abuse, and registry-resident threats, enabling security teams to build robust detections when traditional antivirus fails.

This skill leverages the VirusTotal API v3 to enrich file hashes (MD5, SHA-256). It retrieves comprehensive security data, including multi-engine detection rates, sandbox behavioral reports, YARA rule matches, and related Indicators of Compromise (IOCs). It is essential for SOC triage, incident response, and threat intelligence workflows.

This guide details the process of developing precise YARA and YARA-X rules for advanced malware detection. It teaches analysts how to analyze unpacked malware artifacts—such as unique strings, byte sequences, and PE header traits—to extract stable detection anchors. This skill is crucial for threat hunting, malware family classification, and automating the creation of robust security signatures while aggressively minimizing false positives.

This comprehensive guide details a step-by-step workflow for reverse engineering malware binaries using Ghidra. It guides users through static and dynamic analysis techniques to study internal logic, C2 communication protocols, cryptographic routines, and obfuscation methods at the assembly and pseudo-C code level. Use this when deep code review is required to extract configuration data, understand exploit mechanisms, or develop detection signatures.

A comprehensive guide and technical framework for detecting and mitigating ransomware kill switch mechanisms. It details methods for analyzing mutex guards, domain-based communication, and registry checks. Learn how to deploy proactive mutex vaccination and use Sysmon/DNS monitoring to prevent malware execution during incident response and analysis.

This comprehensive checklist provides a deep dive into Endpoint Detection and Response (EDR) architecture and monitoring mechanisms. It details advanced evasion techniques, such as direct syscalls, AMSI bypass, kernel patching, and memory manipulation. This skill is essential for red team engagements, penetration testing, and advanced malware research to thoroughly assess and bypass modern security defenses.

A comprehensive skill for triaging npm packages and dependency lockfiles against supply-chain threats. It utilizes heuristic scanning (GuardDog), manual tarball inspection, and dynamic detonation in isolated environments to detect malicious behavior such as credential exfiltration, reverse shell execution, and self-propagation. Essential for secure code review and CI/CD pipeline gating.
