For the uninitiated: TikTok is known to send and receive telemetry packages through headers in other requests (IIRC), and employs the use of a virtual machine(!) to execute encrypted client code.

Any source for that? What does "other" requests mean? Other than what? I doubt it could modify the headers of other apps.

Requests it makes for things required to function at all, video data etc. I guess? But this is the first time I've heard this claim.
