Martin Sent: Tue 4/24/2007 1:55 PM To: [email protected] Subject: Re: [IBMVM] Hackers There's an article in the IBM Systems Journal, some time in the late 1970's, that discusses what amounts to a penetration test study of that vintage of VM. If I recall correctly, the authors exposed some interesting quirks in the I/O subsystem as the major exposure to mischief. I've got a copy of the article buried somewhere in my paper ephemera. If you're interested and don't find a better source, I'll dig up the publication info and can perhaps locate my copy of the article. -dan.
