A systematic, multi-phase guide for tackling hard bugs and performance regressions. It mandates building a robust feedback loop (e.g., failing tests, harnesses), formulating falsifiable hypotheses, targeted instrumentation, and rigorous regression testing. This methodology ensures that debugging efforts are structured, efficient, and highly reproducible, making it ideal for complex software defects.

This skill details advanced techniques for exploiting formula injection vulnerabilities within CSV, Excel, LibreOffice, and Google Sheets environments. It covers DDE, obfuscation methods, and high-risk functions like IMPORT* that can be triggered when user-controlled data is exported or imported into spreadsheet software. Use this for penetration testing of data pipelines and export features.

An expert playbook for identifying and simulating dependency confusion attacks in software supply chains. It comprehensively covers how internal package names can be squatted on public registries, leading to malicious code execution via package manager lifecycle hooks (e.g., npm, pip, Maven). Use this guide for authorized red-team exercises and deep vulnerability assessment of build processes.

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. Essential for solving complex CTF challenges, analyzing protected software, or tackling custom runtime environments.
