Read WordPress 5.2: Mitigating Supply-Chain Attacks Against 33% of the Internet by Scott Arciszewski
WordPress 3.7 was released on October 24, 2013 and introduced an automatic update mechanism to ensure security fixes would be automatically deployed on all WordPress sites, in an effort to prevent recently-patched vulnerabilities from being massively exploited in the wild.

However, the WordPress automatic update feature had one glaring Achilles' heel: If a criminal or nation state were to hack into the WordPress update server, they could trigger a fake automatic update to infect WordPress sites with malware.
