This tweet highlights a fascinating case where a security researcher successfully bypassed LG's Web Application Firewall (WAF) using advanced techniques in Blind SQL Injection (SQLi). LG, known for its robust WAF protections, was challenged by this researcher's methodical approach to finding and exploiting a critical vulnerability. Blind SQLi attacks allow attackers to infer data by observing responses to injected queries, even when the output is not directly visible. The researcher used advanced query techniques to extract information, effectively cracking the WAF's defenses that typically block conventional SQLi attempts. This example demonstrates the evolving landscape of web security, emphasizing the importance of continuous testing and updating of WAF rules. For educational purposes, it shows how attackers adapt their strategies against complex filters, reminding security teams to anticipate and mitigate such sophisticated attacks.
