The HTTP/2 protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack.

## Abstract
Network diversity has been widely recognized as an effective defense strategy to mitigate the spread of malware. Optimally diversifying network resources can improve the resilience of a network against malware propagation. This work proposes an efficient method to compute such an optimal deployment, in the context of upgrading a legacy Industrial Control System with modern IT infrastructure. Our approach can tolerate various c

CVE-2016-7153 HTTP/2: HEIST attack allows attackers to sniff TLS encrypted HTTP/2 traffic
HEIST enables an attacker to conduct BREACH attack against HTTP 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".
