I find Paul Thurrott’s Internet Nexus a continual source of perplexity (perplexment? whatever). First annoyance: doesn’t have comments turned on, so one can’t balance the dafter things he repeats or says. Second thing: repeats daft things. Here’s his repeat of an NT Bugtraq warning which fails to pick up on a rather key element of this “vulnerability in the wild”:
“Obviously this is only of interest if an attacker has root (or physical) access to a machine, however…
However, if someone has root (translation: they are God, locally) you’ve already got big enough problems, because they could change your password, and they can access anything you’ve encrypted with Apple’s FileVault. (I’d use PGP anyway.) If they’ve got physical access and a CD - OK, that could be a problem if you haven’t enabled Open Firmware Password, which can disallow someone from starting from anything other than the normal startup disk.
I haven’t looked at this exploit: I expect, based on what’s said, that it’s looking at the swapfiles for longname. (Update: I have, It is.) I saw this reported on an O’Reilly blog a week ago. Read the comments: people tried it and had different results - which suggests to me it’s actually something to do with Appletalk not securing passwords. Many people use the same password all over.
So it’s a vulnerability “in the wild” to the extent that there are hackers prowling around exploiting root vulnerabilities (how many of those are there on OSX, please?) and bearing installer CDs. Except in the latter case, they still have to log into Terminal and then enter a “sudo” (admininstrator) password. Which they’ll get from where, exactly?
This is a classic case of speed-of-light journalism: everyone wants to be first with this story, and to put it on their site first. Nobody brings any expertise to it, however. Result: readers vaguely worried, but not informed.
Meanwhile I had another phishing email (effortlessly spam-trapped by Post Armor) insisting it was “Important Information from Lloyds Bank”. I’d almost feel interested, except I don’t bank with Lloyds. I bet the site it leads you to works perfectly on IE6….
