defanging-and-sharing-iocs

defanging-and-sharing-iocs is a skill for Claude Code, Codex from meltedinhex/analyst-ai-pack. It costs 71 tokens per session (693 once invoked), scanned A, original, Apache-2.0.

A way to prepare indicators of compromise—such as suspicious URLs, domains, IP addresses, email addresses, and file hashes—for safe sharing. It replaces parts of them so people and software do not accidentally open or resolve them, then formats them for threat-sharing tools.

In plain words
What is it for?
Use it to defang and normalize indicator lists, label each item by type, and export them as CSV or a basic STIX-style bundle for platforms such as MISP. It is also useful when preparing indicators for reports and investigation feeds.
Why use it?
It prevents a report, ticket, chat message, or email from creating an accidental link or alerting an attacker. It also cleans duplicate and inconsistently written indicators before distribution.

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

defanging-and-sharing-iocs 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.

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.

What it actually says

Defanging and Sharing IOCs

When to Use

  • You are about to put indicators in a report, ticket, chat, or email and must prevent accidental clicks or resolution.
  • You need to export indicators in a structured format for a sharing platform (MISP/STIX) or feed.
  • You are normalizing a messy indicator list before distribution.

Do not use raw, live indicators in any document a human or tool might auto-process — a clicked URL or auto-resolved domain can tip off the adversary or infect a reader.

Prerequisites

  • A list of extracted indicators (from the IOC-extraction skill) and the target sharing format.

Workflow

Step 1: Normalize the indicators

Deduplicate and canonicalize (lowercase domains, strip trailing dots) so the output is clean.

Step 2: Defang for safety

Apply standard defanging: httphxxp, .[.], @[at], ://[://]. This blocks hyperlinking and casual copy-paste resolution.

python scripts/analyst.py defang iocs.txt

Step 3: Classify and structure

Tag each indicator by type (url, domain, ipv4, email, hash) and emit a structured form (CSV or a minimal STIX-style bundle) for the target platform.

Step 4: Add context

Attach the source, first-seen date, confidence, and related ATT&CK technique so consumers can act on the indicator.

Validation

  • No output indicator is clickable or auto-resolvable (all are defanged).
  • Each indicator is correctly typed and deduplicated.
  • The structured export imports cleanly into the target platform.

Pitfalls

  • Defanging inconsistently, so some indicators remain live.
  • Sharing indicators without context (source, confidence), reducing their value.
  • Over-defanging hashes (no need) or mangling indicators so they cannot be re-fanged for use.

What ships with it

3 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.
