Duh
It was obviously way too easy to break in to NASA...
53-page [GAO] Report to Congressional Committees: http://www.gao.gov/new.items/d104.pdf
"During fiscal years 2007 and 2008, NASA reported 1,120 security incidents that have resulted in the installation of malicious software on its systems and unauthorized access to sensitive information."
1120 times in a two year period was a bit much!
