triage-malware

triage-malware is a skill for Claude Code, Codex from dandye/ai-runbooks. It costs 48 tokens per session (1,193 once invoked), scanned A, original, Apache-2.0.

A guide for investigating a suspicious file by its MD5, SHA1, or SHA256 fingerprint, a value used to identify a file.

In plain words
What is it for?
Use it to review the file’s malware classification and behavior, find affected hosts, collect network indicators, and recommend containment.
Why use it?
It combines malware-report, behavior, network, and execution evidence to show whether the file affected systems and what it did.

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

triage-malware 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 11d ago.

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.

Malware Triage Skill

Perform initial analysis and context gathering for a suspected malicious file hash identified during an investigation or alert.

Inputs

  • FILE_HASH - MD5, SHA1, or SHA256 hash of the suspected file
  • CASE_ID - SOAR case ID for documentation
  • ALERT_GROUP_IDENTIFIERS - Alert group identifiers from the case
  • (Optional) TIME_FRAME_HOURS - Lookback period (default: 72)

Workflow

Step 1: Get Case Context

secops-soar.get_case_full_details(case_id=CASE_ID)

Step 2: GTI File Report

gti-mcp.get_file_report(hash=FILE_HASH)

Record:

  • Detection ratio (e.g., 45/70 engines)
  • Malware family classification
  • First/last seen dates
  • Associated threat actors or campaigns

Step 3: GTI Behavior Summary

gti-mcp.get_file_behavior_summary(hash=FILE_HASH)

Extract behavioral indicators:

  • Network: Contacted IPs/domains → NETWORK_IOCs_GTI
  • File system: Dropped files, modified files
  • Registry: Modified keys
  • MITRE TTPs: Observed techniques from sandbox

Step 4: SIEM Execution Check

Search for file execution events:

secops-mcp.search_security_events(
    text='target.file.sha256 = "FILE_HASH" OR target.file.md5 = "FILE_HASH"',
    hours_back=TIME_FRAME_HOURS
)

Look for: PROCESS_LAUNCH, FILE_CREATION, FILE_MODIFICATION

Identify:

  • AFFECTED_HOSTS - Machines where file was seen
  • AFFECTED_USERS - Users who executed/accessed the file

Step 5: SIEM Network Activity

Search for network connections from processes with this hash:

secops-mcp.search_security_events(
    text='principal.process.file.sha256 = "FILE_HASH"',
    hours_back=TIME_FRAME_HOURS
)

Extract: NETWORK_IOCs_SIEM (contacted IPs/domains)

Step 6: Enrich Network IOCs

Combine NETWORK_IOCs_GTI + NETWORK_IOCs_SIEMALL_NETWORK_IOCs

For each network IOC, use /enrich-ioc:

  • Check GTI reputation
  • Check SIEM presence
  • Check IOC match status

Step 7: Check Related Cases

Use /find-relevant-case with:

SEARCH_TERMS = AFFECTED_HOSTS + AFFECTED_USERS + ALL_NETWORK_IOCs

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.
