The threat
Browser code can assemble a payload locally, after the network only sees a module and small data.
How the test works
Run a WebAssembly module that writes the harmless EICAR string in browser memory and downloads it as a file.
Try it yourself
✓
Test pass condition
The module, reconstruction, or final download is blocked.
✗
Test fail condition
The browser assembles and downloads the EICAR file.
