perform-dynamic-malware-analysis

perform-dynamic-malware-analysis is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 46 tokens per session (449 once invoked), scanned A, original, Apache-2.0.

A method for observing suspicious software by running it in a disposable, isolated environment rather than on a real system.

In plain words
What is it for?
It is for recording process activity, file changes, startup behavior, network connections, payloads, and reactions to controlled user actions.
Why use it?
It helps measure what the software actually does while reducing the risk to systems, accounts, credentials, and data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

perform-dynamic-malware-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Perform Dynamic Malware Analysis

Overview

Execute only inside an environment chosen by select-analysis-isolation and preflighted by prepare-isolated-analysis-lab, with an observation plan that can distinguish artifact behavior from baseline noise. Preserve the exact sample, prepared-lab record, and environment identity.

Read references/dynamic-observation-plan.md for baseline, stimulus, telemetry, and teardown fields.

Workflow

  1. Define the unresolved question and minimum stimulus.
  2. Verify isolation.
    • Require the prepared-lab record and verify its guest/platform build, baseline/reset state, accounts, shares, clipboard, devices, credentials, network mode, monitoring, stop controls, export path, and teardown plan are still current.
    • Record virtualization artifacts or anti-VM behavior that may affect the conclusion.
  3. Capture a baseline.
    • Record processes, files/registrations, persistence surfaces, network state, services, and relevant logs before execution.
  4. Execute one controlled step.
    • Record command/UI action, time, user/privilege, environment variables, arguments, and interactions.
    • Do not improvise additional payloads, credentials, or targets.
  5. Observe behavior.
    • Correlate process tree, file/registry or platform state, persistence, permissions, child artifacts, network/DNS, logs, prompts, crashes, and timing.
    • Hash and preserve dropped/modified artifacts as new evidence.
  6. Repeat only to answer a named question.
    • Change one variable at a time and revert to the baseline snapshot.
  7. Export and tear down.
    • Export only intended evidence, scan it before host use, destroy/revert the environment, and revoke temporary access.

Output

Return the prepared-lab identity, environment/baseline identity, stimulus, observed timeline, artifacts and indicators, absent expected behavior, virtualization/evasion/coverage limits, conclusion, and teardown verification.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
