The targeted cyber attacks apparently originating in China that hit Google
and more than 30 other companies late last year are now targeting some U.S.
defense contractors, according to security vendor F-Secure.
In a blog post this week, F-Secure Chief Research Officer Mikko Hypponen said
the company has learned of instances where malicious PDF files were e-mailed to
U.S. defense contractors last week. The PDF file was designed to look like an
official Department of Defense document and contained information about a real
Mission Planning User Conference to be held in Las Vegas in March, he added.
