Testers can perform deep dives using hardware debugging (UART/JTAG), firmware extraction and reverse engineering, analyzing protocols (MQTT, CoAP, BLE), and simulating cloud-to-device attacks to identify vulnerabilities across all layers of the smart device stack.

A comprehensive guide for statically analyzing suspicious Android APKs. This skill demonstrates how to use JADX, apktool, and androguard to decompile Java/Kotlin source code, examine manifest permissions, and identify malicious patterns. Use this to detect data exfiltration, C2 command and control communication, privilege escalation, and overlay attacks in mobile threats.

A comprehensive guide for reversing and analyzing .NET malware samples. Learn the full workflow, including identifying .NET assemblies, using de4dot to deobfuscate code protected by tools like ConfuserEx or SmartAssembly, and loading the cleaned code into dnSpy. This skill is essential for extracting hardcoded C2 configurations, encryption keys, and credentials, and debugging runtime behaviors of complex malware.

This comprehensive guide teaches advanced iOS reverse engineering techniques using Frida dynamic instrumentation. Users can analyze proprietary app logic, extract encryption keys, trace method calls, and bypass anti-tampering or anti-debugging mechanisms without needing source code. It is essential for authorized mobile security testing and protocol analysis.

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 deep dive into reverse engineering ransomware encryption mechanisms. It details the analysis of hybrid encryption models (AES/RSA), identifying specific cryptographic APIs (CryptoAPI, CNG), and locating implementation flaws such as weak key generation or IV reuse. This guides authorized security professionals in finding potential decryption opportunities without paying a ransom.

A comprehensive workflow and guide for reverse engineering malware compiled using the Rust language. It specifically addresses complex challenges unique to Rust binaries, including non-null-terminated fat-pointer strings, monomorphization artifacts, and intricate error handling chains (Result/Option). Ideal for security analysts and red teams performing deep analysis of modern, resilient attack artifacts.

A comprehensive guide detailing the workflow for firmware reverse engineering. It uses tools like binwalk to identify embedded filesystems (e.g., SquashFS, CramFS), perform entropy analysis to locate hidden data, and extract components. The process covers deep inspection, credential discovery, and reporting for IoT and embedded security assessments.

Covers Bluetooth Low Energy attack workflows, including GATT enumeration, unauthenticated characteristic access, pairing downgrade checks, MITM during pairing, sniffing, and companion app reverse engineering for IoT and consumer BLE devices.

A comprehensive playbook for defeating anti-debugging mechanisms in protected binaries. Covers advanced techniques across both Linux (ptrace, /proc/self/status, timing checks) and Windows (PEB flags, NtQueryInformationProcess). Provides detailed detection methods and corresponding bypass strategies (e.g., patching, hooking, kernel modules) essential for advanced binary reverse engineering.

This playbook provides expert techniques for reverse engineering custom virtual machines and proprietary bytecode. It guides users through identifying dispatchers (switch/table), mapping unknown opcodes, reconstructing custom ISAs, and writing dedicated disassemblers.
