Q41. Samuel is high school teenager who lives in Modesto California. Samuel is a straight ‘A’ student who really likes tinkering around with computers and other types of electronic devices. Samuel just received a new laptop for his birthday and has been configuring it ever since. While tweaking the registry, Samuel notices a pop up at the bottom of his screen stating that his computer was now connected to a wireless network. All of a sudden, he was able to get online and surf the Internet.
Samuel did some quick research and was able to gain access to the wireless router he was connecting to and see al of its settings? Being able to hop onto someone else’s wireless network so easily fascinated Samuel so he began doing more and more research on wireless technologies and how to exploit them. The next day Samuel’s fried said that he could drive around all over town and pick up hundred of wireless networks. This really excited Samuel so they got into his friend’s car and drove around the city seeing which networks they could connect to and which ones they could not.
What has Samuel and his friend just performed?
A. Wardriving
B. Warwalking
C. Warchalking
D. Webdriving
Answer: A
Explanation: Wardriving is the act of searching for Wi-Fi wireless networks by a person in a moving vehicle using a Wi-Fi-equipped computer, such as a laptop or a PDA, to detect the networks. It was also known (as of 2002) as "WiLDing" (Wireless Lan Driving, although this term never gained any popularity and is no longer used), originating in the San Francisco Bay Area with the Bay Area Wireless Users Group (BAWUG). It is similar to using a scanner for radio.

A. NTPCAP
B. LibPCAP
C. WinPCAP
D. PCAP
Answer: C
Explanation: WinPcap is the industry-standard tool for link-layer network access in Windows environments: it allows applications to capture and transmit network packets bypassing the protocol stack, and has additional useful features, including kernel-level packet filtering, a network statistics engine and support for remote packet capture.
Q42. You ping a target IP to check if the host is up. You do not get a response. You suspect ICMP is blocked at the firewall. Next you use hping2 tool to ping the target host and you get a response. Why does the host respond to hping2 and not ping packet?
[ceh]# ping 10.2.3.4
PING 10.2.3.4 (10.2.3.4) from 10.2.3.80 : 56(84) bytes of data.
--- 10.2.3.4 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss
[ceh]# ./hping2 -c 4 -n -i 2 10.2.3.4
HPING 10.2.3.4 (eth0 10.2.3.4): NO FLAGS are set, 40 headers +
0 data bytes
len=46 ip=10.2.3.4 flags=RA seq=0 ttl=128 id=54167 win=0 rtt=0.8 ms
len=46 ip=10.2.3.4 flags=RA seq=1 ttl=128 id=54935 win=0 rtt=0.7 ms
len=46 ip=10.2.3.4 flags=RA seq=2 ttl=128 id=55447 win=0 rtt=0.7 ms
len=46 ip=10.2.3.4 flags=RA seq=3 ttl=128 id=55959 win=0 rtt=0.7 ms
--- 10.2.3.4 hping statistic ---
4 packets tramitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 0.7/0.8/0.8 ms
A. ping packets cannot bypass firewalls
B. you must use ping 10.2.3.4 switch
C. hping2 uses TCP instead of ICMP by default
D. hping2 uses stealth TCP packets to connect
Answer: C
Explanation: Default protocol is TCP, by default hping2 will send tcp headers to target host's port 0 with a winsize of 64 without any tcp flag on. Often this is the best way to do an 'hide ping', useful when target is behind a firewall that drop ICMP. Moreover a tcp null-flag to port 0 has a good probability of not being logged.

Q50. A common technique for luring e-mail users into opening virus-launching attachments is to send messages that would appear to be relevant or important to many of their potential recipients. One way of accomplishing this feat is to make the virus-carrying messages appear to come from some type of business entity retailing sites, UPS, FEDEX, CITIBANK or a major provider of a common service.
Here is a fraudulent e-mail claiming to be from FedEx regarding a package that could not be delivered. This mail asks the receiver to open an attachment in order to obtain the FEDEX tracking number for picking up the package. The attachment contained in this type of e-mail activates a virus.
Vendors send e-mails like this to their customers advising them not to open any files attached with the mail, as they do not include attachments.
Fraudulent e-mail and legit e-mail that arrives in your inbox contain the fedex.com as the sender of the mail.
How do you ensure if the e-mail is authentic and sent from fedex.com?
A. Verify the digital signature attached with the mail, the fake mail will not have Digital ID at all
B. Check the Sender ID against the National Spam Database (NSD)
C. Fake mail will have spelling/grammatical errors
D. Fake mail uses extensive images, animation and flash content
Answer: A
