analyzing-campaign-attribution-evidence

analyzing-campaign-attribution-evidence is a skill for Claude Code from killvxk/cybersecurity-skills-zh. It costs 116 tokens per session (2,168 once invoked), scanned A, original, Apache-2.0.

A skill for analysing evidence to estimate which threat actor or organisation is responsible for a cyberattack. It uses structured methods such as the Diamond Model and Analysis of Competing Hypotheses.

In plain words
What is it for?
Use it to compare infrastructure, attack techniques, malware similarities, timing, language clues, and victim patterns, then report a confidence level.
Why use it?
It helps separate stronger attribution evidence from weak or misleading clues, including possible false-flag activity.

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 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/agent.py, scripts/process.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.

分析攻击活动溯源归因证据

概述

攻击活动溯源归因(Attribution)分析涉及系统性地评估证据,以确定哪个威胁行为者(Threat Actor)或组织对某次网络行动负责。本技能涵盖使用 Diamond Model 和 ACH(竞争假设分析)收集并加权溯源指标、分析基础设施重叠、TTP 一致性、恶意软件代码相似性、操作时序模式和语言痕迹,以构建置信度加权的归因评估报告。

前置条件

  • Python 3.9+,安装 attackctistix2networkx
  • 访问威胁情报平台(MISP、OpenCTI)
  • 了解 Diamond Model 入侵分析框架
  • 熟悉 MITRE ATT&CK 威胁组织画像
  • 掌握恶意软件分析和基础设施追踪技术

核心概念

溯源证据类别

  1. 基础设施重叠:共享 C2 服务器、域名、IP 范围、托管服务商
  2. TTP 一致性:跨攻击活动中匹配的 ATT&CK 技术和子技术
  3. 恶意软件代码相似性:共享代码库、编译器、PDB 路径、加密例程
  4. 操作模式:时序(工作时间、时区)、目标模式、操作节奏
  5. 语言痕迹:特定语言的嵌入字符串、变量名、错误消息
  6. 受害者学:目标行业、地理位置和组织画像一致性

置信度级别

  • 高置信度:多个独立证据类别聚焦于同一行为者
  • 中置信度:若干证据类别匹配,但存在一定模糊性
  • 低置信度:证据有限,可能存在伪旗或共享工具

竞争假设分析(ACH)

一种结构化分析方法,针对多个竞争假设评估证据。每条证据针对每个假设被评分为一致、不一致或中性。不一致证据最少的假设为优先假设。

        ranked = sorted(
            self.hypotheses.items(),
            key=lambda x: x[1]["score"],
            reverse=True,
        )
        return [

                "confidence": self._score_to_confidence(data["score"]),
            }
            for name, data in ranked
        ]

    def _score_to_confidence(self, score):
        if score >= 80:
            return "HIGH"
        elif score >= 40:
            return "MODERATE"
        else:
            return "LOW"
