I will reverse engineer your binary firmware or private protocol

About this gig
需要了解二进制、应用或设备到底是如何工作的吗？我会逆向工程软件、固件和私有协议，然后给你一份技术报告，你可以根据它行动。
我分析的内容
- 静态+动态二进制分析（Ghidra、IDA、x64dbg、radare2）
- 固件解压：文件系统、配置、硬编码密钥、更新格式
- 从应用流量中重建私有协议/API
- 遗留逻辑恢复：从exe中重建未公开的计算或规则
- 混淆、封装器和虚拟机式保护分流
- iOS / Android 应用行为与本地数据格式分析
你能得到什么
- 发现报告：架构、关键功能、数据结构、调用流程
- 带有注释偏移量、符号和函数名称的可复现步骤
- Python 或工具脚本，能帮你节省时间
- 交付后14天的书面问答
范围
我只处理你拥有或授权测试的二进制文件、固件和数据。我不破解授权软件，不绕过DRM或授权，也不帮忙游戏作弊。
不确定你的目标是否可行？给我发消息，告诉我文件类型和你的目标。我会在你下单前，免费一条消息诚实回复。

I am a self-taught reverse engineer based in Xuancheng, China, specializing in static and dynamic binary analysis. I have extensive experience with crackmes, CTF challenges, and firmware teardowns, providing detailed reports on logic recovery and reproducible findings. My technical skills include proficiency with Ghidra, IDA, x64dbg, and protocol analysis using Wireshark.
FAQ
Can you crack or bypass a license, DRM, or activation system?
No. I only analyze assets you own or are authorized to test. Cracking licensed software, bypassing DRM, and game cheats are out of scope and I will decline those orders.
Which tools do you use?
Ghidra and IDA Pro for static analysis, x64dbg / WinDbg for dynamic, Frida for runtime hooking, radare2/rizin for scripted work, binwalk and unsquashfs for firmware, Wireshark and mitmproxy for protocols, Unicorn/Qiling for emulation where it is faster.
Will I get the original source code back?
No one can recover original source. You get behavior-level analysis, rebuilt pseudo-code, and where the budget allows, a clean reimplementation in C#, C++ or Python that reproduces the observed input/output behavior.
What if the target is packed or heavily protected?
Triage is part of every package. If unpacking is a project on its own, I will tell you after the Basic report and quote it as a separate order. You will never be surprised by a hidden cost mid-order.
How fast can you deliver?
3 / 5 / 7 days by package. Rush delivery within 24 hours is available as an extra on Basic and Standard.
