Due to current pandemic conditions like covid-19, every human being depends on web applications. However, the security of database-driven web applications stills remains a challenge. This research aims to understand the topmost web vulnerability [2] i.e. SQL Injection and its impact on financial and government organizations. A set of mechanisms intended to transform SQLI vulnerability into a fully-fledged attack is demonstrated on live secure (HTTPS) banking, government-aided, and financial websites. We intimated these organizations and made them conscious of such a dangerous vulnerability. In the end, we also focused on; how to compromise the SQL Injection by analyzing preventive guidelines.
