At a glance

Check for existing SIEM alerts and case management entries related to IOCs.

  • Works in 2 steps: Correlate SIEM Alerts → Correlate Cases
  • Understand if an indicator has triggered previous alerts
  • SKILL.md covers Inputs, Workflow, Required Outputs and Use Cases, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Correlate Ioc is an agent skill from dandye/ai-runbooks. Check for existing SIEM alerts and case management entries related to IOCs. Use to understand if an indicator has triggered previous alerts or is part of ongoing investigations. Takes IOC list and returns related alerts and cases.

Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Security, covering Security operations. The licence is Apache-2.0.

When your agent uses it

  • Understand if an indicator has triggered previous alerts
  • Is part of ongoing investigations

Example prompts

  • “/correlate-ioc”

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Correlate SIEM Alerts
  2. Correlate Cases

What it can do on your machine

Read from SKILL.md and the folder at commit 72a6863. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Correlate Ioc loads about 624 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 187 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~624

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Correlate IOC Skill

Check for existing SIEM alerts and cases related to specific Indicators of Compromise.

Inputs

  • IOC_LIST - Single IOC or list of IOCs (e.g., ["198.51.100.10", "evil-domain.com"])
  • (Optional) TIME_FRAME_HOURS - Lookback period for SIEM alerts (default: 168 = 7 days)
  • (Optional) SOAR_CASE_FILTER - Additional filter for SOAR cases (e.g., status="OPEN")

Workflow

Step 1: Correlate SIEM Alerts

Search for alerts containing any IOC in the list:

secops-mcp.get_security_alerts(
    query=IOC_based_query,
    hours_back=TIME_FRAME_HOURS
)

Store summary in RELATED_SIEM_ALERTS:

  • Alert count
  • Alert types/names
  • Severity distribution
  • Affected assets
Step 2: Correlate Cases

Search for cases containing any IOC:

secops-soar.list_cases(
    filter=IOC_based_filter + SOAR_CASE_FILTER
)

Store summary in RELATED_SOAR_CASES:

  • Case IDs and names
  • Case status
  • Case priority

Required Outputs

After completing this skill, you MUST report these outputs:

OutputDescription
RELATED_SIEM_ALERTSSummary of SIEM alerts related to the IOC(s)
RELATED_CASESSummary of cases related to the IOC(s)
CORRELATION_STATUSSuccess/failure status of the correlation
MALICIOUS_CONFIDENCEDerived confidence based on alert history: high, medium, low, or none

Use Cases

  1. Before Investigation - Check if IOC is already under investigation
  2. During Enrichment - Understand internal activity for an IOC
  3. Threat Hunt - Find all alerts/cases related to campaign indicators
  4. Incident Response - Identify scope of compromise across cases

Correlation Summary Template

IOC Correlation Summary for [IOC_LIST]:

SIEM Alerts (last [TIME_FRAME_HOURS] hours):
- Total alerts: [count]
- Alert types: [list]
- Affected hosts: [list]

Related Cases:
- Open cases: [count] - [IDs]
- Closed cases: [count]
- Related investigations: [summary]
