Once again, the root cause of the Equifax hack is a web app vulnerability. These type of vulnerabilities have been around for over a decade but are still so relevant today. Each developer should be given the tools to avoid introducing these problems in the first place through training and real-time guidance while developing code.
Equifax said it discovered the breach on July 29. "Criminals exploited a U.S. website application vulnerability to gain access to certain files," the company said.
