Most backdoors pick a lane. AngrySpark built three of them. The DLL, the VM, and the beacon each carry their own encryption, their own API resolution, and their own C2 channel. Compromise one layer and the other two remain opaque.

That architecture is what elevates it from a well-built backdoor to something worth writing up.

If the C2 server responds with HTTP 200 (rather than the expected 302 redirect that delivers encrypted commands), the DLL treats this as a server-side kill command. It runs the same cleanup: wipe registry, schedule file deletion, exit.

This is some next-level evil shit.
