Proxy-Agnostic Session Inference via Audio Compression Artifacts
You spend enough time in stealth and you realize the stack you sweat over—proxies, browsers, headers, entropy, all the rest—only covers the leaks you can see. The big ones. But it’s always the side-channel, the one artifact nobody planned for, that connects the dots in a way nothing else could. Lately, that’s been audio. Not the metadata, not the user agent, but the actual sound your stack delivers—and the micro-mess that compression leaves behind. Audio compression artifacts aren’t something you can rotate, scrub, or spoof with a proxy. They’re the stubborn, noisy, ugly parts of the signal that detectors can use to tie sessions together, long after everything else is burned.
