Jony, a security analyst, while monitoring IIS logs, identified events shown in the figure below.

TheIIS log events indicate a SQL Injection Attack. This is evident from the complex SQL queries present in the log, which include functions like “UNICODE”, “SUBSTRING”, and “MAX”. These functions are being used in a manner that suggests manipulation of strings and extraction of data, which are common tactics in SQL injection attacks. The use of specific characters like CHAR(97) and CHAR(108) within the queries is a technique often employed to bypass security mechanisms during such attacks.
