As an example: Three years ago I was thrown into a week-long sink-or-swim course on malware analysis, taught by an instructor who was a principal scientist at a company that's a big name in that field. (Due to the subject matter of this story, I am not allowed to give names: they don't want to be publicly associated with this story. You'd recognize the company name if you heard it, though.) The first thing we did was crack our cases to verify that our machines had no network cards. While we were doing this, the instructor entertained us with a funny story about why we were doing this. A couple of years before that course, a new piece of malware was reported to the company. In turn it was sent to the malware analysis lab, where the instructor was the guy tasked with looking at it. He was running a Windows VM within a Linux environment on a computer that was physically disconnected from the internet and had the wifi card turned off. He fired up IDA Pro (a popular debugger) and began studying this boring, broken piece of malware. Within a couple of minutes the sysadmins noticed something wrong and killed all network access in the building. All signs pointed to the instructor's machine being the source of the problem. The malware was the work of an evil genius. As input to a PC, it was a bunch of nonsense that crashed hard before it could do anything. As input to IDA Pro, it was a carefully crafted input that hijacked IDA Pro. It then discovered it was running inside a virtual machine, used an exploit to get out into the Linux environment, brought up the wifi connection and associated with the first network it could. Wacky hijinks ensued. You can find some more on this subject in "The IDA Pro Book," by Chris Eagle. NIST also has a brief writeup on it: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2005-0115 _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
