Lenovo Newsroom | LENOVO STATEMENT ON SUPERFISH.

From the bottom of the Guardian link by paperghost/Chris Boyd:

QuoteChris Boyd, Malware Intelligence Analyst at Malwarebytes, recommended that "in this particular case, anybody affected should uninstall the Superfish software then type certmgr.msc into their Windows search bar – from there, they can find and remove the related root certificate."

My concern is not that Lenovo stopped adding it to new computers but rather what is to stop Superfish from re-enabling the server side interactions.  Lenovo should provide the same instructions for removing the root cert to their customers.

Confirmed it was NOT installed on a two month old ThinkPad T440s, which lends credence to it not being pre-loaded on business machines.

Confirmed it WAS installed on a four month old IdeaPad U530.  This goes beyond the Y50, Z40, Z50, G50, and Yoga 2 Pro reports.

In the latter case, uninstalled Superfish via Control Panel > Add/Remove Programs.  HOWEVER, the process did NOT remove the Registry entry and root certificate.  Removing the trusted root certification from Firefox was simple, however I needed to launch IE as administrator in order to remove it.

Well, this didn't take long:  http://www.theverge.com/2015/2/19/8069127/superfish-password-certificate-cracked-lenovo

QuoteThe cracked certificate exposes Lenovo users to man-in-the-middle attacks, similar to those opened up by Heartbleed

QuoteImagine that you are a major global seller of laptop computers and that you were just caught preloading those machines with ultra-invasive adware that hijacks even fully encrypted Web sessions by using a self-signed root HTTPS certificate from a company called Superfish. How do you explain why you did it?

If you're Lenovo, you tell customers that you thought they would like having their visits to banking websites interfered with and their machines left open to potential man-in-the-middle attacks!

Lenovo mentions 3 specific things:

QuoteSuperfish has completely disabled server side interactions (since January) on all Lenovo products so that the product is no longer active. This disables Superfish for all products in market.

Lenovo stopped preloading the software in January.

We will not preload this software in the future.

That's good new for future users but doesn't fix the problem for those who already have it installed.  Lenovo doesn't understand the damage that has been done, not just to customer trust ...  :Win73:

Take the time to run the tool posted earlier:  https://filippo.io/Badfish/

If you get a 'yes', you have the bad root certificate and need to remove it.

One of the security "journalists" posted on Twitter that he checked Lenovo laptops for sale at BestBuy.  Some had Superfish, others didn't.  Obviously, just because Lenovo stopped installing Superfish in January doesn't help the laptops produced prior to that date and sitting shelves waiting for the unsuspecting buyer,

I don't think that there is a news source/journalist that hasn't gotten into the Lenovo/Superfish discussion today.  Excerpts from interview with Lenofo CTO:  Lenovo CTO: We're Working to Wipe Superfish App Off of PCs - Digits - WSJ.

Lenovo posts "Instructions to determine if you have the SuperFish application installed and how to Uninstall it"

http://news.lenovo.com/images/20034/remove-superfish-instructions.pdf

Superfish was only installed on Lenovo Notebook products, not ThinkPad, ThinkCentre, Desktop, ThinkStation, ThinkServer or System x products.

The Lenovo PDF doesn't mention what to do if Firefox and/or Thunderbird are installed.  See the bottom of the instructions here for removing the Firefox & Thunderbird certificate:  http://arstechnica.com/security/2015/02/how-to-remove-the-superfish-malware-what-lenovo-doesnt-tell-you/

QuoteLenovo's Response to Its Dangerous Adware Is Astonishingly Clueless

Indeed

This is disturbing on a personal note as I have purchased several Lenovo laptops over the years, and recommended many times that to friends and family. They make terrific hardware, but this only serves to diminish their brand.

Lenovo's initial "What, me worry?" level of denial is troubling.  They had to have known about this issue since at least 21 January:  https://forums.lenovo.com/t5/Security-Malware/Potentially-Unwanted-Program-Superfish-VisualDiscovery/m-p/1860408/highlight/true#M1697

There was no response until 19 February.

I'd bet that ZERO of their users enjoy the Superfish software pre-installed on their computers  :(

Thankfully my ThinkPad is unaffected.  However, with regards to the IdeaPad, I go out of my way to avoid security vulnerabilities ... and I certainly never elected to buy it with them pre-installed.    :exorcize:

http://www.pcworld.com/article/2886912/lenovo-admits-to-superfish-screwup-will-release-cleanup-tool.html

According to Lenovo's chief technical officer Peter Hortensius, there are plans to release an automated tool on Friday that will remove Superfish from affected PCs.

There have been widespread reports that Lenovo is in contact with browser and antivirus about ways to fix this issue.  For example, delivering the tool as an automatic patch (possibly through partners such as Microsoft) rather than relying on users to download it themselves.  Additionally, they are investigating ways to remove the software from the Windows deployment "preload" of the affected laptops, which is stored on the hidden recovery partition (and used for factory resets).

I didn't even think about the recovery partition.
I guess it's best to clean it off then make an image of only the clean drive C and avoid using the recovery partition.

This was the most understandable article I saw to clean it off
