More fallout from the Flame malware and forged Microsoft certificates. As a result Microsoft is changing the way they handle certificates and which changes an optional update to a critical which will be installed automatically as of today.

Additional details can be found at this link.

This causes the latest "Patch Tuesday" to be really important.

With the Hash Collision costing between 200k and 2 MIL to execute, it shows that the money is there to gain valuble corporate and goverment data.

And we thought we were just doing our jobs.
Now we have become involved with a new kind of struggle.

I avoid Public sector because of this but there is a middle earth between public and private and security is that place.

Perhaps necessary but isn't it unsettling that MS can install updates on your computers even when you select the "Let me know when updates are available but let me download and install them" option?

This happened to me and others, as I realized after furiously googling about this update that installed itself on a day I did not update any servers.

MS Security Advisory (2728973)is mostly house keeping. Those 28 certs aren't being explioted, as far as anyone knows.

Next month though (August 2012), they are going to dump support for RSA keys, which are less than 1024 bits in length. This might cause problems:

This could definitely be felt by IT folk.
