17. Rebecca works as a Penetration Tester in a security service firm named Xsecurity. Rebecca placed a sniffer on a subnet residing deep inside the client’s network. She used the Firewalk tool to test the security of the company’s network firewall. After the test, when Rebecca checked the sniffer logs, she was unable to see any traffic produced by the Firewalk tool.

    What is the reason for this?

    • Rebecca does not see any of the Firewalk traffic because it sets all packets with a TTL of one.
    • Network sniffers cannot detect Firewalk so that is why none of the traffic appears.
    • Firewalk cannot pass through firewalls.
    • She cannot see the traffic because Firewalk sets all packets with a TTL of zero.

18. George, a reputed ethical hacker and penetration testing consultant, was hired by FNB Services, a startup financial services company, to audit the security of their web applications. During his investigation, George discovered that the company’s website is vulnerable to blind SQL injection attacks. George entered a custom SQL query in a form located on the vulnerable page which resulted in a back-end SQL query similar to the one given below:

    http://fnb.com/forms/?id=1+AND+555=if(ord(mid((select+pass from+users+limit+0,1),1,2))= 97,555,777)

    What is George trying to achieve with this custom SQL query?

    • George is searching for the first character of all the table entries
    • George is searching for the second character of the first table entry
    • George is searching for the first character of the second table entry
    • George is searching for the first character of the first table entry

19. An organization hosted a website to provide services to its customers. A visitor of this website has reported a complaint to the organization that they are getting an error message with code 502 when they are trying to access the website. This issue was forwarded to the IT department in the organization.
