While you're correct that PC Trojans is more a threat then somebody
hacking into ADSL modem, the later is still a possibility. If I remember
correctly, there were remote exploits to Alcatel ADSL modems, and if the
modem is connected directly to your internal LAN, you are in trouble. If
the modem is on separate physical interface, and access from/to it is
restricted via firewall rules, maximum you loose your internet
connectivity when your modem is hacked into. This brings another
question: are Alcatel ADSL modems used by Bezeq vulnerable to this
exploit, and if they are, is there any patch or updated firmware which
can be applied to fix it? I'm using Alcatel modem myself now, but was
unable to find any relevant data on the net.
