monitoring-process-and-file-behavior

monitoring-process-and-file-behavior is a skill for Claude Code, Codex from meltedinhex/analyst-ai-pack. It costs 71 tokens per session (709 once invoked), scanned A, original, Apache-2.0.

A malware-analysis guide for summarizing Procmon-style logs from an already isolated sample run. It describes process creation, file and registry changes, and network activity.

In plain words
What is it for?
Use it to reconstruct a process tree, find files or registry entries changed by a sample, and collect network-related indicators.
Why use it?
It turns a large operation log into a concise behavioral profile without running the sample again. This helps analysts connect runtime behavior with other evidence.

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

monitoring-process-and-file-behavior 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/analyst.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Monitoring Process and File Behavior

When to Use

  • You have a Procmon CSV/XML export (or equivalent sandbox operation log) from detonating a sample.
  • You need a concise behavioral profile: child processes, file writes, registry persistence, and network-related calls.
  • You are correlating dynamic behavior with static indicators.

Do not use this to detonate the sample yourself — it consumes already-captured logs. Run the sample only inside an isolated, instrumented sandbox you own.

Prerequisites

  • A Procmon CSV export (or comparable operation log) from an isolated detonation.

Safety & Handling

  • Only consume logs; never execute the sample on an analyst workstation.
  • Defang any captured URLs/hosts before sharing.

Workflow

Step 1: Summarize operations by category

python scripts/analyst.py summarize procmon.csv

Counts operations by class (Process/Thread, File, Registry, Network) and lists the busiest paths.

Step 2: Identify process tree

Extract Process Create events to reconstruct parent/child relationships and command lines — LOLBins (powershell, rundll32, mshta) spawned from the sample are high-signal.

Step 3: Identify persistence and drops

Registry writes under Run/RunOnce/services, and file writes to %APPDATA%/%TEMP%/startup, indicate persistence and staged payloads.

Step 4: Build the behavioral profile

Map observed operations to ATT&CK techniques and defang any network endpoints.

Validation

  • The process tree reconstructs from Process Create events.
  • File and registry writes are categorized with their target paths.
  • Observed behaviors map to specific ATT&CK techniques.

Pitfalls

  • Treating noisy read operations as significant — writes and creates carry the signal.
  • Missing short-lived child processes that exited before capture stopped.
  • Ignoring path normalization (%TEMP% vs absolute) when deduplicating.

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.

monitoring-process-and-file-behavior is a skill published in the GitHub repository meltedinhex/analyst-ai-pack (22 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 71 tokens to every session and 709 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
