SOPHOS: Fraudulent certificates issued by Comodo, is it time to rethink who we trust?

T3h noes, more paranoid blurb, futile attempts to avoid responsibility and mud flinging by Melih. Soooooo lame.  ::)

like I said in a previous post, we might never know how it started. The Comodo guy didn't talk until someone from the Tor network (attacked too btw) found out about Comodo fraudulent certs.

Why not take the Comodo issue directly to Comodo ???
It would be a lot nicer to do it directly on the Comodo forum. :0
Or are you afraid of the Comodo Dragon and would rather not post there  ???

Bob the issue is:

1 solved now for us users, on most affected platforms
2 goes far beyond Comodo's scope of actions; the issue is global, and Comodo was just the button that had to be triggered. Doesn't mean that I trust their CEO's version of how it happened.

If serious action is ever taken against Comodo >>> MS + Google + Yahoo + Skype + Mozilla etc... will do that. It's pointless going to their forums to discuss the issue, while it remains interesting to comment it here.

Yeah that too. Plus the whole way this blunder has been kept secret for over a week has been completely stupid in the first place. There were easy actions to remedy the situation meanwhile by disabling Comodo's and their resellers' root certificates, on the other hand - I totally fail to see who benefited from non-disclosure (beyond the fraud guys). Certainly not users. This completely evades me. FAIL.  :-X >:(

You've got banned because your posts intuito personae against Melih.
We have a problem, a situation.
You can post very hard without getting banned.

As solution, Firefox 4 and IE 9 are protected by default.
IE8 users should change manually a setting.
In any case, update Windows.

Hopefully this causes the industry players to audit not only their own security systems and policies, but those of their trusted partners as well. As the problem of transitive trust remains inherent in the PKI, it's about every link in the chain, not just your own.

Sadly - nope, even with FF4, OSCP is still not set to consider the certificate invalid when it cannot contact the OSCP server by default. So, this can repeat any time again without users knowledge.

You're right. My fault. Users of Firefox 4 should do it manually.

Tech,
There was a whole week that no one knew (almost no one) about the issue.
You can't protect against something you know nothing about.

Agree.
But Microsoft knows that: they've changed the default on IE9 for a reason.
Google seems to knew that.
And also Comodo...
And also Mozilla does not change the default on Firefox 4...

Is anybody thinking on users?
