"Java Regex Under Attack: 8 Billion Ops Per Validation, Because Who Needs a Social Life?"

Java developers are vulnerable to Regular Expression Denial of Service (ReDoS) attacks due to the language's regex engine using backtracking, causing exponential time complexity. This can lead to 8 billion operations for one validation call, crippling servers. Google's RE2 engine, which guarantees linear time matching, can prevent such attacks. A Java validation library called Rules, bundling a patched RE2J fork, is available to mitigate this issue, providing a secure alternative for input validation, and can be integrated via Maven or GitHub, protecting against ReDoS, HashDoS, and timing attacks.
