Detect Shellcode Injection
Detection and hunting methodology for shellcode injection and in-memory execution: CreateRemoteThread injection, PE and DLL injection, process hollowing, thread execution hijacking, APC injection, and reflective code loading (MITRE ATT&CK T1055 with .001 .002 .003 .004 .012 .008 .009, T1620, T1106). Keys off Windows endpoint telemetry: Sysmon EID 8, 10, 25, 7, and 1 / Security 4688, the Microsoft-Windows-Threat-Intelligence ETW provider, Microsoft Defender for Endpoint DeviceEvents, plus Linux ptrace and memfd signals. Gives the allocate-write-execute footprint, unbacked-memory signals, a memory-forensics hunt, and exploit-protection, application-control, and EDR hardening. Use when triaging a suspected process-injection or in-memory implant, hunting for CreateRemoteThread into unbacked memory or process hollowing, investigating RWX private memory, reviewing EDR injection alerts, or hardening a fleet against fileless execution.

What this skill does
Detect Shellcode Injection is a community-contributed Claude Code skill in the appsec-build sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/detect-shellcode-injection/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when triaging a suspected process-injection or in-memory implant, hunting for CreateRemoteThread into unbacked memory or process hollowing, investigating RWX private memory, reviewing EDR injection alerts, or hardening a fleet against fileless execution.
Who uses this skill
The Detect Shellcode Injection Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 211,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Detect Shellcode Injection skill?
Use Detect Shellcode Injection when your Claude Code task falls under the Security category — specifically in the appsec build area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Detect Shellcode Injection" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the Detect Shellcode Injection skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Detect Shellcode Injection is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
