  compression and CRIME attack against TLS compression without being in a man-in-the-middle
  position. HEIST uses a side-channel attack involving TCP-windows to leak the exact size of any
  cross-origin response, without having to observe traffic at the network level. Thus, HEIST enables
  compression-based attacks such as CRIME and BREACH to be performed purely in the browser, by any
  malicious website or script, without requiring a man-in-the-middle position.

  HEIST stands for 'HTTP Encrypted Information can be Stolen through TCP-windows'.");
