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

Joe the Hacker breaks into pass4sure’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 mtu 8232 inet 127.0.0.1
netmask ff000000hme0: flags=863 mtu 1500 inet
192.0.2.99 netmask ffffff00 broadcast 134.5.2.255
