broke: using slight changes in transmitted VoIP audio to leak ECDSA signing keys woke: using them to cheat in counter-strike usenix.org/system/files/s

A paragraph of text from the paper linked in the tweet. The text reads:

We analyze the computation-dependent leakage captured
by internal microphones, and empirically demonstrate its effi-
cacy for attacks. In one scenario, an attacker steals the secret
ECDSA signing keys of the counterparty in a voice call. In
another, the attacker detects what web page their counterparty
is loading. In the third scenario, a player in the Counter-Strike
online multiplayer game can detect a hidden opponent waiting
in ambush, by analyzing how the 3D rendering done by the
opponent’s computer induces faint but detectable signals into
the opponent’s audio feed.

The lines relevant to cheating in Counter-Strike are highlighted.

the numbers match for cs 1.6, and they don't specify GO in the text earlier either.
