Professional 1.6.35

Summary: Burp Suite Professional 1.6.35, released 21 January 2016, adds three new Scanner issues relating to HTTPS: unencrypted communications, mixed content, and strict transport security not enforced. The release notes say mixed content is reported when a page loads over HTTPS but pulls scripts and images over plain HTTP, and that missing Strict-Transport-Security lets a positioned attacker rewrite HTTPS links as HTTP.

What's compelling: The release notes cite mass interception of unencrypted communications by powerful adversaries as the reason for pushing HTTPS everywhere, and note that a suitably positioned attacker can strip SSL by rewriting HTTPS links as HTTP when HSTS is not enforced.
