Sandra is conducting a penetration test for XYZ.com. She knows that XYZ.com is using wireless
networking for some of the offices in the building right down the street. Through social engineering
she discovers that they are using 802.11g. Sandra knows that 802.11g uses the same 2.4GHz
frequency range as 802.11b. Using NetStumbler and her 802.11b wireless NIC, Sandra drives
over to the building to map the wireless networks. However, even though she repositions herself
around the building several times, Sandra is not able to detect a single AP.
What do you think is the reason behind this?
A.
Netstumbler does not work against 802.11g.
B.
You can only pick up 802.11g signals with 802.11a wireless cards.
C.
The access points probably have WEP enabled so they cannot be detected.
D.
The access points probably have disabled broadcasting of the SSID so they cannot be
detected.
E.
802.11g uses OFDM while 802.11b uses DSSS so despite the same frequency and 802.11b
card cannot see an 802.11g signal.
F.
Sandra must be doing something wrong,as there is no reason for her to not see the signals.
NetStumbler (also known as Network Stumbler) is a tool for Windows that facilitates detection of Wireless LANs using the 802.11b, 802.11a and 802.11g WLAN standards.
So, how A can be true here.
It is not true. E) is the answer.
D.The access points probably have disabled broadcasting of the SSID so they cannot be
detected.
The answer is D. I found it on another v7 exam.
NetStumbler, as mentioned previously, uses 802.11a, b and g.
D
So why does question say a,b,g for net stumbler
question 339
D
But what is correct answer? E?
Because D may not – is users are connected already to the AP, they will be sending SSID.
“One of the weaknesses of Netstumbler is its inability to detect Wireless LANS utilising hidden SSIDs.”
Why not is ‘F’?
The correct answer is D.
D is the only correct answer here. 802.11g is backward compatible with 802.11b and thus her 802.11b NIC will work just fine picking up 802.11g signals. The ONLY viable answer here is that we are dealing with hidden SSIDs.
100% is D
