Скачать или смотреть How Hackers Exploit Timing Attacks | Secure Your Website Authentication

In this video, we dive into a common but critical flaw in modern web authentication systems. While hashing passwords and using JWT tokens are best practices, many developers forget about timing attacks — a side channel vulnerability that hackers can easily exploit. I’ll show you exactly how an attacker could use response times to discover valid usernames and how to properly fix your code to prevent this issue. Stay till the end to see the before and after comparisons!
