Q381. 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 Login of user daniel, sessionID= 0x98627579539E13BE Login of user rebecca, sessionID= 0x90627579944CCB811 Login of user mike, sessionID= 0x9062757935FB5C64 Transfer Funds user jason Pay Bill user mike Logout of user mike
