digital-forensics

Lets your agent investigate digital data for evidence. Useful for analyzing memory, disks, network traffic, and preserving important information.

What it does

This tool helps investigate computers and networks to find digital evidence. It analyzes memory, disk, and network data to understand what happened.

When to use it

  • ✓When you suspect a computer has been compromised.
  • ✓To figure out how a cyberattack occurred.
  • ✓To collect digital evidence in an organized way.

Example of what to ask your AI

“Analyze the memory of this computer to find suspicious activities.”

Ready-to-paste message

Use this skill to help me: https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/digital-forensics/SKILL.md Read the SKILL.md file at that link and follow its instructions for my task.
How it works

It uses specialized tools to examine data backups (like RAM or hard drives) and network files. The goal is to reconstruct events and identify malicious activities.

Installation

Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.

In the terminal (Claude Code, Codex, Cursor), in your project folder:

npx skills add zhaoxuya520/reverse-skill --skill digital-forensics

Or download just the file:

Digital Forensics & IR Artifacts

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 读取 ../field-journal/precedent-pentest.md 或组织 IR 授权说明
  2. NOW: 确认是取证/溯源而非进攻性扫描
  3. NOW: 建立 case;证据只读副本优先(原始介质写保护)
  4. NEXT: tool-index;Volatility 等常手动
  5. ACT: 保全哈希 → 时间线 → 关键伪影

适用场景

  • 内存转储分析(Volatility 2/3)
  • 磁盘/ E01 / 落地文件时间线
  • PCAP 溯源与协议还原(可联合 protocol-reverse/)
  • 主机伪影:Prefetch、Shimcache、Event Log、浏览器历史
  • 应急响应 IOC 提炼(联合 malware-analysis/ / threat-hunting/)

工作流

1. 保全

□ 计算 SHA256;记录时区与采集命令
□ 工作在副本上;原始只读
□ chain of custody 备注写入 timeline

2. 内存

vol -f mem.dmp windows.info
vol -f mem.dmp windows.pslist
vol -f mem.dmp windows.netscan
vol -f mem.dmp windows.cmdline

3. 主机伪影

□ 事件日志:Security / PowerShell / Sysmon
□ 持久化:Run 键、服务、计划任务、WMI
□ 执行痕迹:Amcache、Prefetch、BAM

4. 网络

□ tshark 统计会话与 DNS
□ 导出可疑流 → protocol-reverse 或 malware C2 分析

工具链

工具 用途
Volatility 3 内存
Timeline Explorer / Plaso 超级时间线
tshark PCAP
Eric Zimmerman 工具集 Windows 伪影
Autopsy / FTK Imager 磁盘

参考

  • references/forensics-triage.md
  • ../malware-analysis/ ../threat-hunting/ ../protocol-reverse/

路由上下文

上游: MASTER R25
下游: 恶意样本深挖 → malware-analysis;规则 → threat-hunting

任务完成自检

  • 是否保全哈希与副本策略?
  • 时间线是否可复核?
  • IOC 是否脱敏分级?
  • Checklist?
FAQ

What are 'artifacts'?

Artifacts are traces left on a computer by programs or actions, such as temporary files, event logs, or browsing history.

Why is it important to work with copies?

Working with copies ensures that the original data is not altered or damaged during the investigation, preserving the integrity of the evidence.

What is 'chain of custody'?

It is the detailed record of who handled the digital evidence, when, and how, to ensure it has not been tampered with.
