Bank of Timbuktu was a medium-sized, regional financial institution in Timbuktu. The bank has deployed a new Internet-accessible Web application recently, using which customers could access their account balances, transfer money between accounts, pay bills and conduct online financial business using a Web browser.
John Stevens was in charge of information security at Bank of Timbuktu. After one month in production, several customers complained about the Internet enabled banking application. Strangely, the account balances of many bank’s customers has been changed!
However, money hadn’t been removed from the bank. Instead, money was transferred between accounts. Given this attack profile, John Stevens reviewed the Web application’s logs and found the following entries:
Attempted login of unknown user: John
Attempted login of unknown user: sysaR
Attempted login of unknown user: sencat
Attempted login of unknown user: pete `’;
Attempted login of unknown user: ` or 1=1–
Attempted login of unknown user: `; drop table logins–
Login of user jason, sessionID= 0x75627578626F6F6B

What kind of attack did the Hacker attempt to carry out at the bank? (Choose the best answer)
A.
The Hacker attempted SQL Injection technique to gain access to a valid bank login ID.

C.
The Hacker attempted a brute force attack to guess login ID and password using password cracking tools.
D.

Explanation:
The following part:
Attempted login of unknown user: pete `’;
Attempted login of unknown user: ` or 1=1–
Attempted login of unknown user: `; drop table logins–Clearly shows a hacker trying to perform a SQL injection by bypassing the login with the statement 1=1 and then dumping the logins table.
