analyzing-campaign-attribution-evidence

analyzing-campaign-attribution-evidence is a skill for Claude Code from oyi77/1ai-skills. It costs 40 tokens per session (2,447 once invoked), scanned A, original, MIT.

A cyber-investigation guide for judging which threat actor or group may be responsible for an operation. It compares evidence such as infrastructure, malware code, attack methods, timing, and language.

In plain words
What is it for?
It helps collect and assess attribution evidence, compare possible actors, and produce confidence-based assessments for incident investigations.
Why use it?
Attribution is uncertain when clues point in different directions, so investigators need a consistent way to weigh competing explanations.

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

analyzing-campaign-attribution-evidence 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 8d 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.

Analyzing Campaign Attribution Evidence

Overview

Campaign attribution analysis involves systematically evaluating evidence to determine which threat actor or group is responsible for a cyber operation. This skill covers collecting and weighting attribution indicators using the Diamond Model and ACH (Analysis of Competing Hypotheses), analyzing infrastructure overlaps, TTP consistency, malware code similarities, operational timing patterns, and language artifacts to build confidence-weighted attribution assessments.

When to Use

Trigger phrases:

  • "analyzing campaign attribution evidence"

  • "Campaign attribution analysis involves systematically evaluating evidence to det"

  • When investigating security incidents that require analyzing campaign attribution evidence

  • When building detection rules or threat hunting queries for this domain

  • When SOC analysts need structured procedures for this analysis type

  • When validating security monitoring coverage for related attack techniques

Prerequisites

  • Python 3.9+ with attackcti, stix2, networkx libraries
  • Access to threat intelligence platforms (MISP, OpenCTI)
  • Understanding of Diamond Model of Intrusion Analysis
  • Familiarity with MITRE ATT&CK threat group profiles
  • Knowledge of malware analysis and infrastructure tracking techniques

Key Concepts

This section covers key concepts for analyzing campaign attribution evidence.

  • Ensure all prerequisites are met before proceeding
  • Follow the documented workflow steps in sequence
  • Record results and any anomalies encountered during this phase

Attribution Evidence Categories

  1. Infrastructure Overlap: Shared C2 servers, domains, IP ranges, hosting providers
  2. TTP Consistency: Matching ATT&CK techniques and sub-techniques across campaigns
  3. Malware Code Similarity: Shared code bases, compilers, PDB paths, encryption routines
  4. Operational Patterns: Timing (working hours, time zones), targeting patterns, operational tempo
  5. Language Artifacts: Embedded strings, variable names, error messages in specific languages
  6. Victimology: Target sector, geography, and organizational profile consistency
