Joe the Hacker breaks into company’s Linux system and plants a wiretap program in order to sniff passwords and user accounts off the wire. The wiretap program is embedded as a Trojan horse in one of the network utilities. Joe is worried that network administrator might detect the wiretap program by querying the interfaces to see if they are running in promiscuous mode.

Running "ifconfig a" will produce the following:

# ifconfig a

1o0: flags=848<UP,LOOPBACK,RUNNING,MULTICAST> mtu 8232

inet 127.0.0.1 netmask ff000000hme0:

flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,PROMISC,MULTICAST> mtu inet 192.0.2.99 netmask ffffff00 broadcast 134.5.2.255 ether

8:0:20:9c:a2:35

What can Joe do to hide the wiretap program from being detected by ifconfig command?

A.
Block output to the console whenever the user runs ifconfig command by running screen capture utiliyu

B.
Run the wiretap program in stealth mode from being detected by the ifconfig command.

C.
Replace original ifconfig utility with the rootkit version of ifconfig hiding Promiscuous information being displayed on the console.

D.
You cannot disable Promiscuous mode detection on Linux systems.

Explanation:
The normal way to hide these rogue programs running on systems is the use crafted commands like ifconfig and ls.
