What is REA and what can it do?

REA stands for Reverse Engineer Anything, a tool on GitHub that lets AI agents analyze closed software without source code. It can explain how an app works and build a custom version, and works with Claude Code, Codex, Cursor, Gemini CLI and Grok Build.

What kinds of devices have people modified?

One user had Claude Code delete 25 Xiaomi packages from a smart TV and add a new launcher. Another bought a used Lululemon Mirror, modified its software and added a Raspberry Pi to play music and video.

What security risks are involved?

Security reporter Jason Koebler warns that AI-replicated software often contains bugs the user cannot fix. If such software spreads, vulnerable code could be installed on critical hardware and lead to device or network hacking.

3 Key Points

What happened
Users are using Anthropic's Claude Code to rewrite smart TV code and tools like GitHub's REA to analyze closed software, with REA passing 420,000 GitHub stars as of Nov 5.
Why it matters
Such easy modification of closed devices can produce buggy code that, if widespread, may lead to vulnerable software on critical hardware and open the door to malware, according to security reporter Jason Koebler.

Context & Analysis

The trend is a spin-off of the growing capability of AI coding assistants. Previously, modifying closed software required skills, time and effort. Now, as the examples show, a user can simply tell Claude Code a TV model number and have it identify the device over Wi-Fi and replace its software. The GitHub project REA follows the same logic: rather than manually reverse-engineering an app, a user registers an AI agent and asks it to analyze the app and produce a custom version.

The appeal is clear from the use cases: removing ads, reviving a discontinued product, or adding features the original maker never intended. But the same ease of modification is what worries observers. Jason Koebler's warning is not about the hobbyists themselves but about what happens when large numbers of modified, poorly understood software builds circulate. In that scenario, the weak point may not be the AI tools but the devices they touch, and the impact could reach users who never chose to modify anything.
