You wouldn't happen to have been connected to the internet
without a router or firewall of some kind when you did the
new install did you ?? If so, you might want to search back
several days ( I think it was in this group or the general group)
that was named something like "12 minutes to infected" (and the
follow-ups from people who said they had it happen in less than
a minute. If you weren't connected to the outside, then I don't
have any idea how you ended up with "Adam" on your machine.

My firewall was down for about 20 minutes while i reconfigured. Damn, I
still need to obliterate ADAM, how do I get rid of him? Lesson learned -
never take down firewall with a live broadband connection.

If you are connected to Broadband Internet, a Router is highly desired. Its NAT
capabilities act as a simplistic FireWall and many have full FireWalls built in. In
addition, they also have FireWall constructs built in such as port blocking.

As always, I suggest blocking both TCP and UDP ports 135 ~ 139 and 445 on *any* SOHO Router.
This will keep hackers and Internet worms out and keep your PC MS Networking from leaking
out.

We have a dell wireless router and it has an active firewall, however, I
still have the problem which I will resolve thanks to your links. I will take
your advise and block the ports you recommended. First you make the mistake;
Then you get the lesson. I will be more carefull in the future.

Wireless Routers *must* be secured.

Here's why...




ST. PETERSBURG, Fla. - Police have arrested a man for using someone else's
wireless Internet network in one of the first criminal cases involving this
fairly common practice.

Benjamin Smith III, 41, faces a pretrial hearing this month following his
April arrest on charges of unauthorized access to a computer network, a
third-degree felony.
Police say Smith admitted using the Wi-Fi signal from the home of Richard
Dinon, who had noticed Smith sitting in an SUV outside Dinon's house using a
laptop computer.

The practice is so new that the Florida Department of Law Enforcement
doesn't even keep statistics, according to the St. Petersburg Times, which
reported Smith's arrest this week.

Innocuous use of other people's unsecured Wi-Fi networks is common, though
experts say that plenty of illegal use also goes undetected: such as people
sneaking on others' networks to traffic in child pornography, steal credit
card information and send death threats.

Security experts say people can prevent such access by turning on encryption
or requiring passwords, but few bother or are unsure how to do so.

Wi-Fi, short for Wireless Fidelity, has enjoyed prolific growth since 2000.
Millions of households have set up wireless home networks that give people
like Dinon the ability to use the Web from their backyards but also reach
the house next door or down the street.

It's not clear why Smith was using Dinon's network. Prosecutors declined to
comment, and a working phone number could not be located for Smith.

The act of seeking out unsecured WiFi sites is known as "War Driving". The FireWall
protects the WAN/LAN interface. Howeveer, if WiFi is unsecured then the hacker/attacker is
not coming from the WAN side of the equation, he is on the LAN side and is within the
FireWall enclave and the FireWall is a moot point. It's like loocking the door to keep
crooks out but the crook is already indide the house when you locked the door.

You can turn on mac filtering and only allow mac address from your computers
and devices to access the lan. Its just an additional security measure. Also
periodocally check you dhcp client list to make sure there are no
unauthorized uesrs on your connection. This procedure depends on your setup,
the manual or the manufacture of your router can tell you how this is done.
