Artificial intelligence is now interwoven into the ethical hacking…

Modern web applications are deeply intertwined with database systems, and any breach at this level can be catastrophic. Ethical hacking, as a proactive defense measure, seeks to preemptively uncover such vulnerabilities before they can be exploited by nefarious actors. Among the most virulent of these threats is SQL injection—a manipulation tactic that leverages unsanitized input fields to infiltrate backend databases. To address this enduring threat, ethical hackers turn to SQLmap, an advanced yet accessible tool crafted for comprehensive database vulnerability assessment. SQLmap has gained renown for its capability to unearth…
