FWIW, the MAC address on the NIC hardware is the only unique identifier as
most laptops are set up with DHCP, and the IP address is set dynamically.
The MAC address is not foolproof, either, since most wireless routers used
with cable and DSL modems allow manual entry of a MAC address so the ISP
server only sees one computer attached, no matter how many are actually
attached to the router.
I know we'd all like our stolen notebooks back, but I think a few thieves
immolated by a thermite charge would go a LOOOOONNNNGGG way towards
stopping the theft of notebooks in this country, especially with the way the
media would be wringing their hands and wailing about it <:o)

Subject: Re: [DC] Warning... when attending events
Actually, 98% of what's needed to trace a system is already present in not
only the
laptop, but almost any computer.
It's called an Ethernet connection or port, and it has a unique hardware
address. I
am not sure, but I think that this is called your IP address, and in
addition, I
believe that there is also a MAC address.
This hardware address is used anytime that anything is sent thru this port
over any
network of any kind, including the internet.
This is what the Laptop Recovery people are using. Every time you boot your
machine
(or at other specified time periods) a little program is executed, and it
calls home
with a little "packet" to Laptop Recovery, thru that port, which has it's
unique
address, and every step along the way, other unique addresses are added to
the
"routing" of the little "packet", all of which information is saved for a
specified
period of time, so that when you call Laptop Recovery and report your laptop
or
other computer stolen, then they just look at the "routing" information of
the
latest "packets" sent in from your laptop, and trace the route the "packet"
took to
get there all the way back to the Internet Provider your laptop was
connected to,
and thru them they can get the actual phone line or other connection that
your
laptop was actually connected to, which they give to the police, etc.,.
etc., etc..
The obvious problem with this approach, is that the Laptop Recovery or other
similar
programs can probably be easily detected and disabled by any smart thief,
and will
almost certainly be deleted by any formatting of the hard drive, especially
if the
disk partitions are cleaned out and re-partitioned.
The other thing to consider, is that your Laptop, if it's hard drive is not
completely wiped and a new bootlegged OS installed, is probably going to go
the same
route that most cars do that get stolen, which is that they will either go
immediately out of the country (not very far from Lake San Marcos (Exam
Site) to the
Mexican Border, where nobody cares if it was stolen, and where US Law
Enforcement
can't reach), or it will go the way of the "chop shop", where just like a
stolen
car, your Laptop will be stripped for parts and either show up on "ebay" as
an
auction for a keyboard and a battery etc. (which can't be traced), or sold
to
refurbishes and repair shops, just the way stolen car parts are.
The real problem here, is that the solution to the problem needs to come in
the form
of legislation, or as voluntarily implemented program, where an IP Provider
would
voluntarily or as required by law, check your hardware address or MAC
address
against a "hot sheet" every time you logged in, and immediately report it
and the
"access location" to the local police or FBI if there was a "match".
The truth be told, I wouldn't be a bit surprised if such a program already
exists as
a part of "Echelon" or "Homeland Security", that is used to track
"terrorist" (and
other subversive democrats), but which would never be used or revealed for
such a
minor inconvenience as the loss of your laptop (since it would expose the
existance
of the program), unless of course you were a "terrorist" (or subversive
democrat).
Anyway, enough for that subject, except to say that the Laptop Recovery is
only as
good as the installed software base on your hard drive is, since once
reformatted or
otherwise detected and disabled, it will no longer call home.
As to the software approach, probably one of the simplest approaches would
be to
write a little program that would load at boot up, and if not disabled by
the
execution of another program (possibly requiring a separate password), would
wait 30
minutes (so that it wouldn't be immediately detected and the hard drive
reformatted)
and then by software turn up the volume of the internal sound card full
blast, and
start screaming something like "Call the Police, this Laptop is Stolen" from
an
embedded MP3 file, and make other car alarm type sounds.
A really good approach to this, would also take into account the software
power
disabling capabilities, such as "Suspend Mode" and other things such as an
executable program that would continue to scream every time your laptop
booted up,
or went into "Suspend Mode" rather than powering off, so that it would
scream again
in something like 1 or 2 minutes, even though the "lid" was closed, as the
thief
though he or she was safely retreating.
Then of course there is the "embedded exploding purple die pack" for your
laptop,
like the banks use for stolen money.
If the truth be told, and if there wasn't the chance that we ourselves might
forget
and be caught off guard, there is also the trick of embedding a small brick
of C3
into your laptop so that the thief would get his.
Getting back to the issue of your laptop calling home, another sneaky little
trick
would be to embed a program that would literally email home yourself once a
week,
using an "alternate email address", one that you would not have to change,
and one
that you could set up on your ISP email account in addition to your regular
email,
so that when your laptop was stolen, it would wait for the first ISP
connection that
was made after every one week time interval, and write you an email home
with at
your alternate email address with a new copy of your address book, so that
you would
not only have the "routing" of the email, but also any new additions to your
address
book, made by the thief, so that you can turn all of his friends and
aquaintances
in, or send them an email threatening to expose them everyday until they
"give him
up".
This could be very easily done on the order of how many viruses work today,
in that
it could cause your "outbox" to add a "footer" to every email that notified
the
recipient that the email was generated on a stolen laptop, and to call you
for a
reward, or better yet just "explode" like a regular virus and send everyone
in the
address book a message that says this laptop has been stolen from you,
please notify
you and then call the police and identify the sender. Just make sure that
your
"alternate" email address is in the address book.
Back tio the Exam site, I suggested to Bill and Mary on the following day
that we
should put another laptop out under similar conditions and appear to all go
to lunch
again whilst someone hid in the room to catch the thief if he came back for
the new
bait, but they didn't think that would work.
Realistically, this is a problem that really could be solved, especially by
the
laptop manufacturers, but the truth is that on the one hand nobody wants the
invasion of privacy that would be involved, notwithstanding that invasion of
privacy
is probably currently going on right now already, and on the other hand,
they really
would rather sell you a new laptop anyway.
Oh well, life is to short for the hassle and high blood pressure brought
about by
even thinking about the things that we all have had stolen from us by the
scum of
the earth.
Maybe the actual course to really resolving this issue would be a brick of
C3 hidden
in the stolen laptop that could be remotely detonated by an email sent out
to the IP
or MAC address after it was stolen, by some service like Laptop Recovery.
I wonder how many times this email will be "tagged" by "Echelon" or some
other
"Homeland Security" monitoring system.
