Are Browsers Using The HTTP/2 Protocol Vulnerable to Heist Attacks?

Are Browsers Using The HTTP/2 Protocol Vulnerable to Heist Attacks? (Malware and Vulnerabilities)

HEIST, a new HTTP/2 protocol exploit, can steal encrypted content from HTTPS traffic. Expert Michael Cobb explains how this attack works and how to stop it. While the HTTP/2 protocol was designed to improve security and performance, it's also apparently enabled threat. HEIST is a side-channel attack on HTTPS. For the HEIST attack to work, a webpage must include or reflect part of the browser's request in its own content, and the user must have JavaScript and third-party cookies enabled. If there are reports of the HEIST attack, users should consider turning on the private browsing mode offered by major browsers. This feature, which disables third-party cookies, would prevent the HEIST script from being able to authenticate with the HTTPS protected webpage.
