analyzing-ransomware-leak-site-intelligence

analyzing-ransomware-leak-site-intelligence is a skill for Claude Code from killvxk/cybersecurity-skills-zh. It costs 65 tokens per session (3,372 once invoked), scanned A, original, Apache-2.0.

A threat-intelligence workflow for monitoring ransomware data-leak sites, where criminal groups publish victim names or stolen-data samples to pressure payment. It focuses on collecting and analyzing information about ransomware activity.

In plain words
What is it for?
Use it to collect data from approved monitoring sources, structure leak-site intelligence, analyze attack trends, and assess ransomware risk for a particular industry.
Why use it?
It helps security teams track victims, timelines, target industries, and changes in ransomware-group activity without relying on unstructured browsing.

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-ransomware-leak-site-intelligence scanned grade A with 1 finding 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/agent.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.

分析勒索软件数据泄露站点情报

概述

采用双重勒索模式运营的勒索软件(Ransomware)组织在 Tor 隐藏服务上维护数据泄露站点(DLS),在那里发布受害者名称、被盗数据样本和倒计时器以施压付款。2025 年上半年,96 个独特勒索软件组织活跃,每月约发布 535 名受害者。监控这些站点提供了关于活跃威胁组织、目标行业、地理模式和新兴勒索软件家族的情报。本技能涵盖安全收集 DLS 情报、提取结构化数据、追踪组织活动趋势,以及生成行业特定风险评估。

前置条件

  • Python 3.9+,安装 requestsbeautifulsoup4pandasmatplotlib
  • Tor 代理(SOCKS5)用于访问 .onion 站点,或商业 DLS 监控情报
  • 了解勒索软件双重勒索商业模式
  • 熟悉主要勒索软件家族(Qilin、Akira、LockBit、BlackCat、Clop)
  • 访问勒索软件追踪情报(Ransomwatch、RansomLook、DarkFeed)

核心概念

双重勒索模式

现代勒索软件组织在加密受害者数据之前还会将其外泄(Exfiltration)。泄露站点作为公开施压工具:受害者以倒计时器、部分数据样本和文件目录的形式被列出。若未支付赎金,完整数据将被公开。部分组织已转向三重勒索,追加 DDoS 威胁或直接联系受害者客户。

DLS 情报价值

泄露站点提供:受害者识别(公司名称、行业、国家)、攻击时间线(列出时间、截止日期、数据发布时间)、数据量估算、组织能力评估(目标行业、攻击频率、操作节奏),以及趋势分析(新组织出现、组织品牌重塑、执法打击)。

安全收集实践

切勿在生产环境中直接访问 DLS 站点。使用专用监控服务(Ransomwatch、DarkFeed、KELA、Flashpoint)、Tor 隔离研究虚拟机、商业威胁情报平台或社区维护的数据集。所有分析应在隔离环境中进行,并获得适当授权。

实践步骤

步骤 1:从公开情报源导入勒索软件泄露站点数据

import requests
import json
import pandas as pd
from datetime import datetime, timedelta
from collections import Counter

class RansomwareIntelCollector:
    """从公开追踪来源收集勒索软件 DLS 情报。"""

    RANSOMWATCH_API = "https://raw.githubusercontent.com/joshhighet/ransomwatch/main/posts.json"
    RANSOMWATCH_GROUPS = "https://raw.githubusercontent.com/joshhighet/ransomwatch/main/groups.json"

    def __init__(self):
        self.posts = []
        self.groups = []

    def fetch_ransomwatch_data(self):
        """从 ransomwatch 获取勒索软件受害者发布数据。"""
        resp = requests.get(self.RANSOMWATCH_API, timeout=30)
        if resp.status_code == 200:
            self.posts = resp.json()
            print(f"[+] 已从 ransomwatch 加载 {len(self.posts)} 条受害者记录")
        else:
            print(f"[-] 获取记录失败: {resp.status_code}")

        resp = requests.get(self.RANSOMWATCH_GROUPS, timeout=30)
        if resp.status_code == 200:
            self.groups = resp.json()
            print(f"[+] 已加载 {len(self.groups)} 个勒索软件组织画像")

        return self.posts

    def get_recent_victims(self, days=30):
        """获取最近 N 天内发布的受害者。"""
        cutoff = datetime.now() - timedelta(days=days)
        recent = []
        for post in self.posts:
            try:
                discovered = datetime.fromisoformat(
                    post.get("discovered", "").replace("Z", "+00:00")
                )
                if discovered.replace(tzinfo=None) >= cutoff:
                    recent.append(post)
            except (ValueError, TypeError):
                continue
        print(f"[+] 最近 {days} 天内 {len(recent)} 名受害者")
        return recent

    def get_group_activity(self, group_name):
        """获取特定勒索软件组织的所有发布记录。"""
        group_posts = [
            p for p in self.posts
            if p.get("group_name", "").lower() == group_name.lower()
        ]
        print(f"[+] {group_name}: 共 {len(group_posts)} 名受害者")
        return group_posts

collector = RansomwareIntelCollector()
collector.fetch_ransomwatch_data()
recent = collector.get_recent_victims(days=30)
