Dell Accused of Installing 'Superfish-Like' Rogue Certificates On Laptops (theregister.co.uk)
Mickeycaskill writes: Dell has been accused of pre-installing rogue self-signing root certificate authentications on its laptops. A number of users discovered the 'eDellRoot' certificate on their machines and say it leaves their machines, and any others with the certificate, open to attack. "Anyone possessing the private key which is on my computer is capable of minting certificates for any site, for any purpose and the computer will programmatically and falsely conclude the issued certificate to be valid," said Joe Nord, a Citrix product manager who found the certificate on his laptop. It is unclear whether it is Dell or a third party installing the certificate, but the episode is similar to the 'Superfish' incident in which Lenovo was found to have installed malware to inject ads onto users' computers.
He is running a pre-installed Windows?
First thing I do is wipe any new computer clean. The OEMs can't be trusted anymore.

I don't think it is "accused" any more. It's pretty much proven.
No chance.
This "install your own root CA" trick is being used widely in corporate environments to allow proxies to snoop your HTTPS connections ; caused no end of trouble with clients using independent Firefox installs (Chrome uses the system certificate store, Firefox has it's own) navigating to our pages (with properly signed certificates) and being told they were a security risk.
We also had something that directed traffic while we were out of the corporate network through a third-party proxy that used the same trick (Websense).
That's easy to solve. MS will sell you an Enterprise Root CA Server system which _can_ install into client root CA stores. It's only $10,000 plus $100 per CAL for every client system the root CA is installed on.
Reading the FA: yes, the private key is on the machine.
and then the people who use Linux based systems will just do it the free way and it's antitrust to block that.
Not only is the private key supplied with the certificate, unlike with SuperFish the certificate can also be used to sign executables. Which means that the bad guys can now sign their malware with eDellRoot and gain unwarranted trust. It figures that slashdot doesn't provide a good link. Try http://arstechnica.com/securit...

Firefox told them it's an untrusted cert and a security risk because it's an untrusted cert and a security risk.
What you are doing is bad, evil, and wrong. And it's technically illegal under the DMCA as well, because you're breaking encryption. No, an employee agreement that says you can monitor their computer use doesn't get you past the DMCA.
Fuck you and all the places that do this. If I were asked to implement such a thing at my job I'd raise all hell and strike.
So Dell satisfies its corporate customers.
... y'know... it has to be said, this is precisely why thinkpenguin (and other FSF-Endorsed hardware) do wipe-it-down-to-the-bedrock products, even to the extent of replacing the standard BIOS with coreboot, and why the purism librem laptop exists (and was successfully funded last year). but even there, the problem is that for the past 15 years all intel processors have to have an RSA-signed bootloader that goes into EEPROM on-board the processor, where there's absolutely no chance of obtaining the source code for that proprietary firmware blob. you have absolutely no idea what goes into that bootloader, but it's already been demonstrated that your laptop - and your desktop - can be woken up by external network signals - without your consent or knowledge - *even when you powered them down*.
the only possible solution here is... to not use intel (or AMD) processors. and that opens up a whole can of worms, which is why i've been sponsored to make an upgradeable laptop. if any one CPU is ever found to have problems, the whole CPU Card can be popped out and replaced... *without* having to throw away the entire laptop.
designing a laptop from the ground up so that its main CPU module can be replaced... only two years ago that could have been said to be "total paranoia". now we have the kinds of stunts being pulled by Dell, Lenovo and the NSA which were only previously believed to *potentially* be carried out...
Heh, as pointed out at the bottom of that article someone in Dell marketing needs to eat some serious humble pie:
http://www.dell.com/us/p/xps-1...
"Dell is serious about your privacy
Worried about Superfish? Dell limits its pre-loaded software to a small number of high-value applications on all of our computers. Each application we pre-load undergoes security, privacy and usability testing to ensure that our customers experience the best possible computing performance, faster set-up and reduced privacy and security concerns."
Youch.
It's not just laptops. We confirmed it was on a Dell Precision 5810 desktop workstation, purchased early May 2015.
Guess I shouldn't trust Lenovo or Dell for new machines.
Don't step on the baby.
At least they're honest, apparently you get faster set-up, you get reduced privacy and you get security concerns.
The problem isn't that it's self-signed - it's that they gave it the maximum possible authority and shipped it *with the private key included*, rather than just the public key.
So, now *anyone* on the internet can sign their malicious web traffic, application, or driver with Dell's key and it will be trusted by all affected Dell computers. This would allow, for example, impersonating financial or e-commerce websites to steal people's credit card numbers or other personal data.
When Lenovo did the same thing a while back, they were using it to spy on and inject ads into people's web traffic - even supposedly private encrypted sessions.
Brilliant reply, I take back anything negative I've ever said about Slashdot and the commentators.
In companies, using a device like BlueCoat, or another, and dropping the root cert into AD for it to be auto-trusted isn't unheard of.
However, I'm seeing this being done more and more with adware. In fact, when helping to clean some infections, when I was doing a quick forensic check before saving documents and wiping the box, almost all the machines with adware/scumware had a root cert added, and all traffic going through some local VPN or proxy. This is of course fixable, but if this is done, who knows what other stuff is installed, so it is best to just save critical stuff and start all over.
There is one way around the WPBT install (which has been around for almost a decade, mainly used to reinstall LoJack for Laptops), and that is to install an OS which acts as a hypervisor (ideally a non-Windows OS which doesn't give a hoot about WPBT), then do the rest of your work in a VM. Of course, this makes gaming almost impossible, but it is a way to mitigate the damage that WPBT installed software is able to do.
I personally don't mind software that an OEM wants to have installed with Windows, especially drivers for NICs and core items which are difficult to just fetch and download. However, the ideal would be to have an install/recovery image of Windows on a read-only flash partition, ideally with the ability to boot more than one Windows edition (so a machine that initially came with Windows 7, got upgraded to Windows 10 has the option to boot and install from either.) At the minimum, the user should be prompted and given the option to install each signed package, or just decline everything.
According to heise.de, just marked "non-exportable" (sorry, no English link):

Person that reported this initially:
https://www.reddit.com/r/techn...
Apparently being non-exportable is no protection whatsoever, and people are already offering the CA cert for download, which then lets everybody sign for this CA.
It is hard to display more fundamental incompetence with regards to certificate handling.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
