Think Like A Hacker With Wordfence

A recent discussion among WordPress core developers about removing support for code signing in core caught our attention. Code signing support was included with the WordPress 5.2 release. The discussion centers around removing code signing and implementing SSL verification and hashes to verify code integrity. In this week's episode we chat about the history behind the vulnerability found by Wordfence's Matt Barry, which is what motivated the addition of code signing to WordPress core. We review several high profile supply chain attacks and discuss how SSL and hashes would not protect against a sophisticated attack on WordPress core servers.
