A security analyst is trying to determine if a host is active on a network. The analyst first attempts the following:
$ ping 192.168.1.4
PING 192.168.1.4 (192.168.1.4): 56 data bytes
192.168.1.4 ping statistics
4 packets transmitted, 0 packets received, 100.0% packet loss
The analyst runs the following command next:
$ sudo hping3 - 4 -n -i 192.168.1.4
HPING 192.168.1.4 (enl 192.168.1.4): NO FLAGS are set, 40 headers + 0 data bytes
len=46 ip=192.168.1.4 ttl=64 id=32101 sport=0 flags=RA seq=0 win=0 rtt=0.4ms
len=46 ip=192.168.1.4 ttl=64 id=32102 sport=0 flags=RA seq=1 win=0 rtt=0.3ms
len=46 ip=192.168.1.4 ttl=64 id=22103 sport=0 flags=RA seq=2 win=0 rtt=0.4ms
len=46 ip=192.168.1.4 ttl=64 id=32104 sport=0 flags=RA seq=3 win=0 rtt=0.4ms
10.0.1.33 hpaing statistic
4 packets transmitted, 4 packets received, 0% packet loss
Which of the following would explain the difference in results?
A. ICMP is being blocked by a firewall.
B. The routing tables for ping and hping3 were different.
C. The original ping command needed root permission to execute.
D. hping3 is returning a false positive.
Correct Answer: A
