> Prebuilt binary blobs [1]? My understanding is that the binary blobs were test data. Find a bug that happens on certain input. Craft a payload that both triggers the bug and does the malicious thing you want to do. Add the binary blob to /tests/files/. Then write a legitimate test to ensure that the bug goes away. Then do some build script bullshit to somehow get that binary into the build.
