Hi Bob,

I assume you are referring to the Root CA store. These are basically the CA's that your device trusts to sign for the authenticity of other certificates. MY understanding of the Lenevo Superfish iisue wasn't that there was malicious code in the cert, but rather by having the cert in the trustes root CA store, users were unknowingly trusting all certs signed by the SuperFish cert. Simply removing it from the store, will prevent the device from automatically trusting a cert signed by tha CA. I don't know of any software that scans for "bad" certs. I know with Firefox, you can enable OCSP checking for certs.

I hope this helped.

Trusted CA's

Hey Bob,

I am not aware of a comprehensive list, or software out there that indicates who to trust. Some of the industry major players are Verisign, Digicert, Geotrust, Thawte, GoDaddy, Network Solutions & Comodo. But this is not an exhaustive list by any means.

I know this isn't very helpful, but trust like beauty is in the eye of the beholder. Wink

Looks like another area to find scanner or such tools soon.

Yep, Not only do we now have to consider the crapware that is pre-installed on devices, but now with the SuperFish goat rope, we now have to worry about crapcerts.

I booted to a USB Linux MInt with Firefox, deleted all the Certificates except for Verisign. Took awhile to get them all too! I then visited some places and they didn't display correctly unless I started adding certs back in. The biggest was Google certificate which opened up a lot of sites that wasn't displaying correctly. Forums at CNET however worked OK without added certs, so maybe they use Verisign still, as in the past. Eventually however after doing yahoo and aol mail and some other pages I discovered most if not all the major certificates by adding what was offered from those sites, were back in the Certificates area of the browser again.
