Description
Hi HN,I just wanted to share what I have been working on for the past few months: A firmware analyzer for embedded Linux systems that helps uncovering security issues running entirely in the browser.This is a very early Alpha. It is going to be rough around the edges. But I think it provides quite a lot of value already.So please go ahead and drop a firmware (only .tar rootfs archives for now) and try to break it :)

Could you build this?
Partial While the web frontend is straightforward, compiling embedded Linux firmware extraction tools (binwalk, squashfs, ubifs parsers) to WebAssembly and running security heuristic engines client-side is technically demanding.
What it would actually take: The stack uses WebAssembly compiled from C/C++/Rust utilities (such as squashfs-tools, unblob, or binwalk components) running inside browser Web Workers. The hard part is porting complex filesystem unpacking tools that depend on POSIX kernel behaviors to the sandboxed WASM/WASI environment and handling multi-hundred-megabyte firmware images entirely in browser memory.
