A comprehensive guide and workflow demonstrating how to use YARA rules for proactive threat hunting. This method helps detect unknown malware, suspicious patterns, and Indicators of Compromise (IOCs) across filesystems, memory dumps, and network artifacts, making it essential for incident response and security analysis.

This skill teaches the comprehensive process of developing precise YARA rules for malware detection. It covers techniques such as identifying unique byte patterns, analyzing strings, and inspecting PE file headers to create robust signatures. Ideal for security analysts performing threat hunting, incident response, and security auditing.

A comprehensive guide for reverse engineering Android malware. It details how to use JADX and accompanying tools (apktool, androguard) to analyze APK metadata, extract permissions, decompile Java/Kotlin source code, and identify malicious functionalities like data exfiltration, C2 communication, and overlay attacks. Ideal for mobile threat analysis and security research.

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 deep dive into advanced malware reverse engineering techniques. Learn how to utilize Ghidra's powerful disassembler and decompiler to analyze complex malware binaries. This guide covers identifying C2 communication protocols, extracting cryptographic routines, understanding memory injection, and analyzing low-level assembly code for core logic and evasion techniques. Essential for professional cybersecurity analysts.

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.

This skill provides a deep dive into the architecture of low-level keyloggers. It covers techniques such as kernel driver hooks, using WH_KEYBOARD_LL, ETW-based input capture, and analyzing user-mode vs. kernel-mode approaches. Use this methodology to understand input capture mechanisms, research EDR evasion methods, or analyze malware architecture for advanced security threat detection.

A comprehensive guide for advanced memory forensics using Volatility 2 and 3. This playbook covers artifact extraction, including hidden process detection, network connections, credential dumping, DLL analysis, and code injection detection (malfind). It is essential for incident response, malware analysis, and reconstructing attack timelines from memory dumps.

Pi-hole is a powerful, network-wide DNS ad blocker solution that runs on Linux hosts (like Raspberry Pi). It automatically blocks ads, trackers, and malware domains for every device on your network without requiring browser extensions. This guide details installation via Docker or bare-metal setup, configuring it as the primary DNS server for a home network, managing blocklists, and implementing advanced features like DNS-over-HTTPS (DoH) for enhanced privacy.

A comprehensive guide on segmenting a home network using VLANs to dramatically enhance security. Learn how to isolate different device types—such as IoT gadgets, guests, and servers—from main PCs, preventing cross-segment malware spread and unauthorized communication. Covers setup steps for UniFi, pfSense, and OPNsense.
