Skill UI

This comprehensive skill guides the process of rapid malware triage and classification using YARA rules. It covers advanced techniques for writing detection rules based on unique strings, specific byte sequences, and structural PE characteristics. It is essential for security analysts building automated detection pipelines, scanning endpoints, or performing large-scale threat hunting across an enterprise environment.

A comprehensive guide for analyzing .NET malware (C#, VB.NET, F#) using professional tools like dnSpy and de4dot. Learn to decompile code, identify obfuscation techniques (ConfuserEx, SmartAssembly), extract C2 configurations, and debug malicious behavior in stealers and RATs.

A comprehensive guide and Python tool for reverse engineering Rust-compiled malware. It addresses unique Rust binary challenges, such as non-null-terminated strings and monomorphization. The script extracts crate dependencies, identifies suspicious capabilities (like networking or encryption), and filters for malware-related strings, assisting security researchers in deep binary analysis.

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.

Pi-hole is a powerful, network-wide DNS ad blocker that runs on Linux hosts (like Raspberry Pi). It intercepts all DNS queries on your local network, blocking advertisements, trackers, and known malware domains before they reach your devices. This guide covers setup via Docker or bare metal, configuring network DNS, managing blocklists, and enabling secure DNS-over-HTTPS (DoH) for enhanced privacy.
