Hunt ReDoS (CWE-1333, Catastrophic Backtracking) — identify regexes with nested quantifiers or overlapping alternation that cause super-linear matching time, trace tainted input paths to regex sinks, demonstrate timing PoC, and validate with response-time delta. Covers PCRE/RE2/V8/Python re engine differences. Triggers on: 'ReDoS', 'regex denial', 'catastrophic backtracking', 'redos', 'regex complexity', 'nested quantifiers', 'regex amplification', 'CWE-1333'.

Hunt and validate reentrancy bugs — classic cross-function, same-function, read-only, and cross-contract variants.

External knowledge integration — HackerOne reports, PayloadsAllTheThings, Book of Secret Knowledge, CVE PoC corpora, bug bounty methodologies, and reference pentest agent architectures. Use these to calibrate, look up payloads, and accelerate research.

Android APK malware analysis — manifest permission review, smali disassembly, Java decompilation with jadx, dynamic instrumentation with Frida, network traffic interception, native library analysis, and automated scanning with MobSF.

.NET malware analysis — dnSpy/ILSpy decompilation, de-obfuscation (ConfuserEx, .NET Reactor, Babel, Crypto Obfuscator), behavioral analysis of managed assemblies, PowerShell cradle extraction, and config decryption for common .NET RAT families.

In-memory and fileless malware detection — AMSI bypass analysis, reflective DLL injection, CLR-hosted payloads, process hollowing, PowerShell cradle chains, WMI/COM persistence, and registry-resident payloads. Covers detection, memory forensics, and payload extraction.

Router / IoT firmware extraction pipeline — unpack nested filesystems, locate web server, identify backdoor credentials.

Analyze an authorized binary through the active Ghidra runtime and verify navigation in the mirrored GUI.

iOS IPA static analysis — class-dump-z / class-dump-ng, Hopper / IDA / Ghidra for Mach-O ARM64, Objective-C runtime introspection, Swift demangling, App Transport Security check, plist analysis, embedded provisioning profile parse. For dynamic Frida/Objection see mobile/SKILL.md.

Fast malware triage workflow — static (PE/Mach-O/ELF format, strings, imports, signatures, entropy/packed indicators), dynamic (sandbox with INetSim, Wireshark, Process Monitor, Procmon, time-shift), unpack (Scylla/PE-sieve), then full RE with Ghidra/IDA. Designed for ≤15 min initial verdict.

Root pointer for the binary reversing lane. Covers triage, Radare2 fallback, string extraction, packer unpacking, virtualized protectors, symbol risk, ROP, Ghidra deep analysis, and firmware extraction.

Ransomware family identification and analysis — encryption scheme identification, key recovery techniques, ransom note parsing, shadow copy/recovery inhibition analysis, decryptor availability check, and IOC extraction for common ransomware families.

Rootkit detection and analysis — UEFI rootkits, kernel-level rootkits, bootkits, DKOM techniques, SSDT/IDT/IRP hooking, hypervisor rootkits, and firmware implant detection using GMER, Volatility, chipsec, and UEFITool.

Fast-path binary triage — identify format/arch/mitigations, grab high-signal strings and imports in under a minute.

VMProtect, VMP2, Themida, and CodeVirtualizer reversing workflow using Radare2/Ghidra facts and Back Engineering Labs research guidance.

YARA rule authoring + hunting — `condition:` syntax, hex patterns with wildcards, `for`/`any of them`, PE module, ELF module, hash module, math module. Build per-family signatures, hunt at scale via VT/MalwareBazaar/Hybrid Analysis. Avoid common pitfalls (collisions, slow rules, regex traps).

Legitimate RMM tool abuse — deploy or hijack Atera, ScreenConnect, AnyDesk, TeamViewer for persistence, lateral movement, and C2. Leverages trusted software to evade EDR and blend with IT admin traffic.

Read and interpret the system-provided Rules of Engagement while planning with the operator.

ROP/JOP gadget hunting and exploit-chain construction — for NX/DEP bypass on x86/x64/ARM binaries.
