When IU who lives in Seoul tried to do SQL Injection attack a certain WEB site, suddenly the browser was closed abnormally. What is the SQL Injection value she tried to enter and when the browser was closed? The time is based on Korea Standard Time(UTC +09:00)
Time Format is YYYY-MM-DDThh:mm:ssTZD (TZD : +hh:mm or hh:mm)

And there we have the answer.
