Phoenix Unveils Anti-Theft BIOS
linuxwrangler writes "According to articles at PC World, c|net, Internet Week and elsewhere, Phoenix Technology is introducing a new BIOS-based anti-theft system. Every time a TheftGuard equipped machine connects to the internet it pings a server at Phoenix which can instruct the machine to wipe its hard drive, report its location or disable itself. Given that most people don't want to have their every movement tracked and don't want someone else to have the power to wipe their drives, Phoenix figures that corporate clients are the prime customer. I just wonder who is liable when a company sells a surplus laptop on eBay but gets their inventory control screwed up and reports it as stolen..."
It was stolen. Police are investigating.
Last I checked, the BIOS was in a socket. What stops someone from swaping out the bios chip before turning on the box?
If this technology were to fall into the wrong hands (read government, RIAA, others) life could truely suck. I hope it never materializes in its current form, or we could have a rather large problem on our hands.

I wonder if that kind of system would be vulnerable to spoofing attacks? That would be a pretty nasty trick to play on someone; erase their hard drive by puting a phoenix spoofing server on their network.
What happens if the user is running Linux? I can't see the bios pinging anything without the help of the host OS. Let alone erasing hard drives. Linux will become the thieves OS of choice. It's my OS of choice when looking at a computer that's been disabled by a virus.
Damn Mozilla!
I logged more hours going back to corporate offices and disabling these "features" and assisting their admins mine out old data then I did installing them. I had to stand there and be told how "God damned stupid all of these features are, and how stupid Dell is for using them, and how stupid you are for working with Dell!!!!". This is when I was 19 and had no more business/customer support experience/skills then a guy serving fries at McDonald's. The shit sucked.
Murphy's Law dictates that the benefits of this idiotic and restrictive measure will be over shadowed by it's rare glitch and/or user incompetence which results in the loss of data.
What happens when your battery dies on the SQl server, and the default settings enact this horrid "feature" and your hard drive is slicked? How bad will it suck when it happens to the CEO's assistant's laptop and she comes storming into your pitiful excuse for a NOC right before you were supposed to go on lunch?
Just imagine (no, not a beowulf!) someone breaking into the Phoenix site and instructing every HD to wipe itself. Now Nimbda looks like a joke...

Aww! How do we expect to get an "early release" of Doom 4 now?
I am surprised that federal departments/agencies have not developed this yet given the large numbers of laptops that go missing every year. Some of them even have classified data on them with the classic example being a certain former head of the CIA who was a little loose with his Powerbook.
Visit Jonesblog and say hello.
Why not just encrypt the whole hard drive or the just sensitive data? To the thief, it's as good as it being erased.
Besides, in either case, if the thief were an enterprising individual they could recover the data. Empty hard drive? Just do a low level scan. Encrypted hard drive? Spend lots of time and resources trying to crack the key.
With that, why not go for the least destructive measure? Unless, of course, Phoenix is going for the Mission Impossible market -- this laptop will erase itself in 20 secs...
just a thought: how many corporate (or otherwise) IT admins would actually trust a system that enables someone beyond their control to remotely wipe their hard drive clean?
what if you restrict the pings to the phoenix servers? i'm sure people will put up the IPs eventully.
and what if i completely disconnect it from the internet?
I'm the Devil the Windows users warned you about.
In other words, it will traceroute the ip and find out where it is geographically located, and then contact the ISP to find out who was on at that time. If it is reported stolen it shouldn't be that difficult for the police to get a court order to get the ISP to reveal that information.
I would like to report that as a beta tester this new bios has served me flawlessly. I have 100 percent faith that I will never suffer any loss of data on its behalf. For all you skeptics out there I can guarantee....
<CARRIER DISCONNECTED>
Microsoft, the RIAA, and other such organizations have been misusing the words piracy and theft to such an extent lately that the instant i saw anti-theft in the headline my immediate, visceral reaction was to think okay, whatever this is, it has nothing whatsoever to do with preventing theft, and is probably just there to prevent you from fully using your computer, until a split second later when I remembered who Phoenix is, and that if phoenix were selling an "anti-theft" BIOS that would actually be what it is.

I wonder if we're going to just kind of accidentally grow into some kind of wierd, reverse "newspeak", like in 1984, except instead of the government purposefully banning negative words, dodgy politicians, media outlets, and corporate officials will simply misuse all of the negative words there are until they've all lost their meaning in the public mind.

Quick -- where's 106.223.16.98 right now.
Why not just rewrite the BIOS and flash it to disable or eliminate these features. Of course only your Uber Geek would be able to do this (certainly not I) and IMO, if he/she can do it, they've EARNED the laptop.
Once this BIOS is hacked (assuming it can be), how long before copies of BIOS start going out over Kazaa?

Does this just stop people stealing computers, or will it stop them stealing product names also? ;)

I just wonder who is liable when a company sells a surplus laptop on eBay but gets their inventory control screwed up and reports it as stolen...
Exactly the same thing that would happen if someone checked the serial number and found it was reported stolen. Police investigate, the owner provides a transaction history, the original owner discovers the mistake, charges get dropped, original owner gets sued for negligence.
And should the HD get erased the FIRST TIME someone connects to the internet, it's not likely to create any serious data loss issues. The owner would probably think there's just something wrong with the computer. They'll complain, the problem will be discovered, etc etc.
Of course, this theftguard assumes a number of things. Certainly the BIOS won't have any interaction with the internet unless the OS permits it. Any intellegent thief would wipe the drive and resinstall without ever booting it, let alone connecting it to the internet. There are many other ways to trace a stolen computer once it gets online, assuming the OS wasn't reloaded first. Having a machine "check in" isn't a bad idea in theory, but there's no particular advantage to using a hardware solution over a software one.

I cannot seriously see anyone accepting this tech.
Corporations *might* but only if they can set it to poll THIER servers, and have it under their control.
Personally though.. it scares me that MS and their "Trusted Computing" scheme Might force this onto the users..
There is only three people/organizations that should have the ability to remove/restrict "owned" things... Me (the owner), The LAW (only after following the judicial system) or Judge Dredd.
"Consider how lucky you are that life has been good to you so far. Alternatively, if life hasn't been good to you so far
When a TheftGuard-equipped system is stolen, the owner provides instructions through the TheftGuard web site. The next time the lost computer connects to the Internet, TheftGuard is activated and either disables the machine, wipes its hard drive, or transmits information on the physical location where the signal originates.
The problem with this seems to be that TheftGuard only performs actions after the stolen computer is connected to the Internet. And by the time that happens (if that happens) it's too late. My understanding is that when computers are stolen, the data on them is what's sought, as it is what's most valuable. And once the data is in the wrong hands, it's too late. The data on it can be copied to another place, and perhaps individual hardware components can be removed and sold. Am I wrong about anything here?

Well, all you would have to do is a trace route back to the offending computer and you could probably get pretty close. Several routers are registered so that they lat/long are known to various trace route programs, making it easier to pinpoint someone. But even if you don't have a program like that, most host names will have some clue as to what state/city you're in.
In my organization, we have been using Computrace which serves the same function. The software installs into the computer's boot sector and is nearly invisible if you don't know to look for it. It contacts the Computrace NOC frequently over IP or modem and reports it's IP address (or caller ID). We now have a pretty nice log of where all our laptops go. The software isn't capable to destroying or disbling the PC, but it's invisibility and reporting features are enough to make it useful.
Computrace reports having retrieved a number of stolen computers based on the data reported by the software. It's definitely useful for any corporate IT department!
From my experience, CEOs usually have very very fine assistants.
Hey, maybe she is actually very technically capable, and consciously activated the erase-all-data feature just so have an excuse to talk to you, give you a chance to ask for her extension etc. =)
Aww shutup and let me daydream.

"Since TheftGuard's also in the BIOS, even if you remove the hard drive, we can still track or disable the machine, or wipe the drive," he said. Another trick that can eradicate anti-theft software -- running FDISK to reformat the drive -- also is foiled by TheftGuard's place in the HPA section of the hard drive, which is immune to simple reformatting tools.
Any hard disk forensics person will tell you the wonders of dd and netcat working together. Adjust the dd parameters a tad, and the HBA is no longer a problem. If they think the bad guys don't have access to this knowledge, they're as FDISKed as they seem.
This is seriously stupid, so it must have come from marketing, not the techies.

... I guess anything with Phoenix BIOS can't safely be used for mission-critical systems then.
I remember reading an interesting article somewhere about a guy who got his mac back by using some remote software on there. It reported its IP address every time the theif connected to the net and as I recall, the guy was uploading scripts to it and so forth to get it to do various things to help recover the box.
I remember thinking at the time that this was a neat idea, but having a third-party with the power to frag my hard drive does not fill me with comfort.
Regardless of how the system works at the technology level, it is potentially open to attack via social engineering... "Hi Phoenix, it's Fred from SCO... those nasty Linux people have pinched my laptop... yep, frag it please..."
I hear people here rant about the evils of microsoft, which I will be the first to agree they are a big evil, but seldom do I hear about the BIOS monopoly.
I'm i'm not mistaken, award, ami, and pheonix are owned by the same company. Atleast Award and Pheonix seem to be at anyrate. I could be wrong about this, but this would be due to the lack of attention on this little piece of software you are required to buy.
Unlike the Microsoft software where you at least (all though arguably) have a choice to buy a system without it... the same can't be said about the BIOS. Now they have a good product... worth paying for, though I wish they would have added some more *nix like features quite frankly, and it's a pain when one motherboard has for example the Symbios boot for cheep scsi cards feature, where another motherboard with the same make bios is missing that feature, dispite the fact that it's been shown this could be added with ease, and heaven forbid any end user requests for these features present in one and not the other.
So, when Pheonix decides to be most irrating and implement systems like this, who are you going to turn to? I honestly don't know the actual cost of the bios licensing and it's cost per PC motherboard, but I'd wager to guess it's pretty cheep... based on what i've seen in old computer shopers, some companies were charging like $20 a chip. I assume it's a sub $20 per chip fee. I personaly am happy to pay it, as these companies pretty much became comercialy viable because they undersold Compaq and IBM, and dispite their flaws they are the lesser of the big blue and wannabe blue.
This is one of those products that you pretty much either *assume* you have legit license for, based on faith that the motherboard maker. For your average geek, it's pretty much a simple task to establish wether or not you have license for the product.
It's also one of those products that the end user doesn't typicaly pirate. Pirated, or rather, bootleged bios are typical found on the cheepest motherboards available. I do not feel that this is the solution as it's not typicaly the end user pirating their product, it's little no name companies that buy their product bulk from the likes of PC Chips and resell them without a licensed bios.
*SOLUTION* why not ask for cash? You may say what you will about these companies, but unless the freebios projects mature enough there isn't really much of an alternative, and it is a product worth paying for as it does make the system work, and i'm all for supporting them as they pretty much are, in part, responcible for the whole clone market, until something better comes out. If their product is indeed typicaly sub $20.00 for that little holographic sticker, this is a VERY small price to pay for updates. During y2k, they would have made a KILLING on all those cheep ass funky motherboards if they were able to provide on their website the correct bios based on it's ID number, explain that you need to pay $20.00 to download it, rather then the more foolish end users who bought copies of that Symantic product to compensate for only level 2 complience.
The alternative is getting bad press about some little old lady who bought a system on good faith, who in good faith bought a system, getting her hard drive wiped because of someone else bootleging a product she doesn't understand exists.

This is a far saner, less failure prone solution to "The Problem". I have already seen similar hardware solutions used by a friend who develops commercially sensitive commerce stuff, the laptop's a paperweight without the key-card.
Only keep your keys on a something like a USB keychain rather than proprietary hardware. Then attach it to said employee's security pass so they don't leave it plugged into the laptop (or keep a log that emails you every time the laptop is shut down with the USB key left plugged in).
But alas, I can see the PHBs of the world will demand the Mission Impossible version because it sounds cooler.

"Everything is adjustable, provided you have the right tools"
It always amazes me when some student at my campus steals a lab computer and doesn't think that our DHCP server will let us know the next time it gets plugged back in to our network. Over half our stolen computers get recovered that way. Just last night, one was stolen (end of the academic year is always bad for theft) and the kid decides to plug it in in his room. He really should have waited 5 more days to use it and he would have graduated on time. Now he is facing expulsion. Idiots!
Wow. I can totally see something like the Slammer virus coming along and either wiping out Phoenix's computers and screwing them up badly, or just attacking all computers and forcing the ones with this BIOS to do some pretty nasty stuff. Of course, this will only teach more people to back up their data more often.
Kind of reminds me of Hackers. "Hackers of the world unite!"
woot.
I sell out to The Man every day.
Now, just how upset would you be if someone came to your door and said that the laptop you bought on eBay last week was stolen? Granted, you'd try to contact the seller to get your money back, but if he's been even the slightest bit clever about things, you might never find out who it was. Further, even if you *DO* find out who the guy is, you still won't get your money back because he'll probably be doing jailtime in the very near future, if he isn't already. Of course, you can legally sue him, but just how do you think you're going to collect?
Not that I'm saying that theft should be ignored... it shouldn't. But doesn't anyone think that efforts might be better spent on technologies that might enable them to catch the criminals *BEFORE* they exploit someone else?

...if my network connection is down? Will my machine refuse to boot?
I think some of the technical folks on here have missed the point: A 'ping' signal doesn't have be the regular ICMP ping. It could be any sort of protocol that requests an echo back from the target.
...just my 3 cents worth (Canadian funds :-)
I do think that an awful lot of people on here are getting the point: What happens when I, mister malicious black
hat decides to spend a little money on research material and aquires, by one menas or another, a few of these units for destructive testing and reverse engineering? Now I can spoof the Pheonix server on any given LAN and - proof - Merry Christmas, Bob's your uncle!
I can see the military and paramilitary organizations liking something like this. I'd also be surprised if they don't have something similar under lock and key right now. If I recall, most of the concern over the laptops wasn't over the data on them, but more over how the security procedures when awry. There were one or two that went missing from internal areas that wouldn't have been equipped for travel, but they likely wouldn't have been protected by this system either.
Personally, I think people fall into one of two categories:
1) The stupid/ignorant. These people wouldn't buy this BIOS anyway. They're gonna be hooped when their data gets lost/stolen.
2) The paranoid. These people are probably already using strong encryption, finger print scanners, etc. They're gonna be hooped as well... unless they were paranoid enough to do regular backups! Admittedly, the thief won't have access to the data, but I suspect most of the stolen laptops get wiped shortly after the thief copies the porn off for his own amusement anyway.
I see IT managers loving this because it covers their arses. I see the users either not needing it or not liking it.

Does anyone recall the low-level format utility that used to be built into hard drive controller ROMS?
All we need now is some script kiddie to figure out the address of the "ZAP" routine in the Phoenix BIOS to jmp to, then the next outlook virus will cause hell. Change one instruction anywhere in your system's software (I guess boot sector is as good as any, before protected mode) to jump to that point, and all is lost.
Why bother with your own devious erase code, when Phoenix thoughtfully provides one for you?
You are in a twisty maze of processor lines, all alike.
There is a lot of hype here.
I see all these posts about sniffing and other attacks but how about the question of how Theftguard's website actually authenticates that YOU are the owner of the pc being reported stolen. What if the data needed is ON the pc or some other easily bypassed measure. This is doomed.
It's cheep security, None of the peripherals seem to be protected and that's the meat of any system.
If you buy a used PC with that system in it you should have the ability to contact the maintainer of the system to work out ownership transfer. There should be no fee for this.
Prediction by MrPredicter:
One week after deployment a copy of the BIOS will be posted to usenet, Seventy Six Milliseconds after that it's cracked, patched and offered on WareZ sites with instructions on how to burn, unplug or desolder and install the new chip.
Fixing the above, off the top of my head:
Hardwired into the motherboard is a distributed encryption device that holds all of the motherboard chips, drives, ram and compatible installed cards in an inactive state until a USB or other device is insterted. The unlocking device needs to have been activated with a PIN prior to insertion so that the secret key inside can encrypt a challenge response with the devices in the computer. The device in the computer should also do realtime transparent encryption of the drives and offer network encryption as it would be trivial to add. Internal keys in the device would be the provence of the local IT security staff, they could not be changed by the user.
One nice feature of this method is that, with a well setup OS each users network presence (data, settings, drives ect) could be transparently encrypted, each PC would be generic with no user or company data stored on the PC just on the network. Other networkable protocols could be implemented. I think Linux is close to part of this done in software.
The device would need to be distributed, that way an attacker would have to compromise every device in the computer to make any use of the computer. Even the ram would not be of use.
It would be possible to do this in a compatible way to protect the addons use extenders/risers that contain the encryption receivers which would be epoxied to circuit cards, drives and ram would slightly reduce cost and void warranties but allow easier upgrades by just adding a riser. The other method is to order specially modified hardware and only the Motherboard needs this. Yes, there are all sorts of drawbacks mostly stability issues and the CPU is stil not protected from theft.
Isn't there some sort of specification for all this, this didn't just come to me a vacuum, well I vacuumed it up, most probably from the cypherpunks mailing list but can't remember.
Total added cost to the PC, too much:
Just hire a damned good degreed security specialist and a retain a good physical security consultantcy and let them work with a team of people to implement a reasonable security system and stick with it. Add to that good training for the security people and rigorous *reoccuring* background checks. Also a mid/upper level management that actually listens to the experts in this is needed, eviserate the dead weight as needed.

It's directly across the road from 106.223.16.96, stupid. Gee whiz, you'll never be a cop.
Never fight naked, unless you're in prison...
So if an evil minded Hax0r gets his hands into Phoenix' server, or manages to get at the keycodes and to redirect the trafic, he can wipe all of any corporations laptops if they adopted this scheme?
That means they're introducing a risc to get their business fscked (or rather formatted) if they depend on those laptops and need to connect them to the internet. I think that's a high price to pay to protect against the theft of a few laptops.
Also it doesn't even work: maybe it's hard to change the BIOS chip (given a replacement BIOS and the right equipment it should be doable), but if the thief is really interested in just the data he simply reads it without conecting the laptop to the internet, or he even removes the harddisk altogether and analyses its contents.
If they really want to protect their data they should go for encrypted filesystems or at least encrypt the sensible data so only authorized persons can access it, problem solved.

As it stands now, this looks like a bad idea, as expressed multiple times by many of the comments. Besides the technical problems, to me it points to a larger problem that is growing every day: Private businesses trying to provide law enforcement.
Assuming they could get past all the potential technical hurdles regarding security and authentication, we still are basically saying that a private company can alter/damage the contents of a computer legally without any coordination with law enforcement. That scares me.
Basically, this is sort of a computer version of low-jack. Which is cool. But in this version, it would be as if you could call up the low-jack people, have the car disabled, get a report of where the car is and take care of the matter yourself. Of course, as far as I can tell, low-jack doesn't work that way. My roommate can't find my documentation for the low-jack, make a phone call and leave me stranded just to play a joke.
I'd like to see this system in place. I for one sure would be happier to know that if somebody stole one of my laptops there was some method out there to recover it. But that's a job for the police, not some big business. Sure, Phoenix can build tools that I might buy that would assist the police, but I'd want to be dang sure that they can't do anything to one of my machines until the cops tell them it's all right. And the cops can't tell them that until I've filed a police report and asked them to do it.
Yes, I know that law enforcement has a long way to go to really get a handle on computer based crimes, and at the moment are pretty impotent in catching the bad guys. But what I don't like seeing is big faceless corporations coming in and picking up the slack.
The Internet is generally stupid
Do most recent laptops have one?
I know most/many desktiop motherboards have a jumper that allows you to reset the BIOS.
Wouldn't that disable this "feature"?
B.
Eades hopes the TheftGuard logo--which could be presented in a visible place on the laptop--would itself deter thieves. By installing protection at the BIOS level, the standard process of reformatting or replacing hard drives won't work. The machine, then, is virtually useless to any thirds party (unless, of course, they can stay off of the Internet).
Exactly. As long as they stay off internet, nothing happends. And of course, the computer might be valueless then, if you don't wanna change any parts. But you can get out the data. And since the aim here is not to protect the computer (Well...that also since it can give location), but Data! And when you put a mark on a computer, it will say to the thief: Hey. Take me, but don't connect to the internet. If this shall work, it has to be hidden. I do not think I would connect such computer to the internet. So then you are back at starting line? Maybe a computer that called home, via satelite or GSM networks. Then it would be far more difficult to cut off. But again, then it would have to be "Don't call, we call you", the Phoenix side would have to call your box, saying hello, can you please get rid of that sensitive data?. Anyway, the BIOS is hardwired...so go on....change.

Oh gee, like thats gonna be REAL popular with people.. How long will it take an enterprising young 14-year-old to write a little hack that sits on a network, opens promiscuous mode on a NIC, watches for calls to Phoenix's verification IP, and answers back with a smurfed "AAGH! DANGER WILL ROBINSON!" reply before Phoenix, Inc. has a chance to?
And I, for one, don't want the operation of my machine to be wholly dependent upon whether or not it's connected to a public network.
Stupid idea, if you ask me.
You want PC security? A note on the wall that says "If you screw with this machine, I'll know, and i'm quite capable of kicking your ass, having you fired, or both." will do the trick nicely.
Seriously..When I was in HS, the guy who ran the computer room was massively anti-piracy. If he even *suspected* you were using pirated shit in the lab, he'd confiscate your disk and literally staple it to the wall. Got the point across.

SMI = System Management Interrupt.
a tashts/2525 16.htm
When an SMI is triggered the system jumps to a special memory space called SMM. SMM space can only be accessed/modified when in SMI. The BIOS implements the handler and the handler cannot be taken over by the OS. Lots of events can cause an SMI. That is a possible mechanism.
Check out the feature in chapter 5 of the ICH5 datasheet

Before everyone goes crazy bashing Intel, every x86 chipset/system supports SMI since 386.
You are both correct, although the original poster added an unnecessary "i" in his usage.
However, while english accepts the plural "viruses", the technically correct plural form of "Virus" is "Viri". We are of course going with the Nominative plural form of the the latin noun Virus (meaning Poison). But you probably already new this fact and the fact that many english words are derived from latin (focus, foci would be another example of the same situation).

I think the main problem with computer theft is not the loss of some more or less cheap piece of hardware. That can be replaced easily. The major damage is that you'll lose your data. But security measurs like the harddisk security features that are stored in a hard disks firmware make it very hard to get access to the data. Especially considering that a normal thief is not an IT expert.
If industrial espionage is concerned then your enemy has enough knowledge to do bad things when he has real phyical access to the machine. So a BIOS won't help much to keep an expert away from my data if I don't do additional measures.
What would be really helpful against data loss is a BIOS that goes on strike if I don't do backups of my data frequently... but that leads us to the problem that there is no easy way of backing up 80 Gigabytes on a 3.5 inch floppy...
Let's face it, the thief who steals it won't have the problem, it'll be the poor sap daft enough to buy it at the end of the chain. Just like the stolen coded (i.e. not-working) car radios which get sold at the local pub/garage sale/car boot sale - who's going to have all the necessary gear to check it at the time of purchase.
By the time the buyer realises, the thief is long gone - it just moves the problem, doesn't eliminate it. Just like the car immobiliser law brought in here in Western Australia - all cars have to have them. So now we get people being attacked near their cars or in the house so the thief can get the keys.
Go permanent? In your dreams and my worst nightmares.
Time for tin foil underwear!
The truth shall set you free!
Likewise, it doesn't take more than a little research to find someone who can make "Phoenix Theft-Guard Protected" stickers for your laptop for a few pennies a pop.
Personally, I'd go with the "This Laptop is GPS enabled and filled with C4 explosives set to go off when reported stolen. Enjoy life with your three out of ten fingers."
No, no, no.. It's inelegant to extend a latin root by just adding extra "i"s.. To be true to the spirit of the language, surely it would be more appropriate to proceed thusly:
4 viruses = viriv
9 viruses = virix
1001 viruses = virmi
etc..
Actually, the grandparent post suggests the first viable attack on this that I've seen suggested here - the other attacks (network tricks, etc.) rely on Phoenix's BIOS designers being so amazingly technically incompetent that they wouldn't cryptographically sign the "kill yourself" message.
This attack, however, relies only on a single instance of minor social incompetence by a call-desk employee. Attacks like this have already been shown to work on large corporations who are supposedly in the business of verifying identity - remember when VeriSign handed out two certificates for "Microsoft Corporation" to people who just asked for them?
The disadvantage of this attack is that it would in all likelihood be relatively easy to trace who had done it - it's highly unlikely that Phoenix's call center would accept a "my laptop's been stolen" call from a pay phone, and their procedures may even call for confirming any theft report by calling the supposed rightful owner back.
However, depending on the relationship between Phoenix and the major OEMs, the attack may get easier - it may be much easier to get Phoenix to think that I'm a Dell call-center employee reporting the theft of Mr. BigWig's laptop than to convince Phoenix that I'm Mr. BigWig or his authorized representative. That's something we'll have to wait and see on - it all depends on how the social network between Phoenix and the large OEMs are designed.
I'm certain that there's no one thinking up a technical attack here on slashdot that's viable against this system in the field. However, I have a reasonable expectation of incompetence from large corporations when it comes to designing the social network half of this system.
Some guy in the Phoenix marketing has a brilliant idea ! Let's "market" the bios so that every year the user is forced to buy a "security upgrade" and let's call it a "security feature". At worse we'll blame either pirates like some other big company does, or we'll blame hackers. I hear the master hacker is hiding in caves...
It seems obvious to me they want to extract more money out of customers by crippling the bios rather then by really improving it.
This idea goes completely against my most trusted and effective security practice. Don't give even the most trusted person more access than need, or in this case, don't give them an ability you wouldn't want anyone in the world to have. The idea of my computer being a tracking device, or for that matter wiping out it's hard drive is not appealing to me. Anyone know how good this things' authentication is?
Karma: Bad. Mostly because the only moderators that notice me are conservatives.
