Today Microsoft is releasing a patch for a bug that allows escalation
of privileges in all supported versions of Windows.
See https://technet.microsoft.com/en-us/library/security/ms14-nov.aspx
Why doesn't this exploit have a name? Why isn't the whole world going
crazy like they did with the heartbleed bug? The fact that the bug is in
all versions of Windows implies that it's been out there for a long
time. We don't know what the bug is, who found it, or how many systems
have already been compromised. If you google for news about this bug,
you won't find anything. But you willfind plenty of stories about
similar exploits from the past.
Why does every linux exploit seem like the end of the world while
Windows exploits get nothing but yawns? Microsoft does a better job of
controlling the announcements. You are not going to get Microsoft to
speculate on how much damage could be done in the worst case scenario
the way people do with the linux exploits. Microsoft has control over
how the problem is perceived and they have every reason to downplay it.
Microsoft has control over the message because nobody except the bad
guys can look at the code and figure out how to take advantage of it If
you come out and say, "Oh, I see how you can take advantage of this
bug," Microsoft is going to say, "Wait a minute. How did you get our
code?" But believe me, it's out there. As a provision of selling Windows
in China, Microsoft had the turn the Windows source code over to the
Chinese government.

According to a security expert at a conference I went to last summer,
this is how the Windows source code got out. The bad guys got it by
hacking into systems in China. In fact, China itself used the code to
devise attacks.

So now the bad guys have the Windows source code but the good guys
don't. It's a false perception caused by hype that leads people to
believe that Windows is more secure than linux.
