根據華爾街日報的報導，駭客入侵美國國防部的電腦，下載數TB的F-35資料。這篇報導是從國防新聞網站上看到的，原文的鏈結是：http://www.defensenews.com/story.php?i=4048737&c=AME&s=TOP

WASHINGTON - Computer spies have hacked into the Pentagon's most costly weapons program, The Wall Street Journal reported April 21, raising the prospect of adversaries gaining access to top-secret security data.

Citing current and former government officials, The Journal said cyber-intruders were able to copy several terabytes of data on the $300 billion Joint Strike Fighter project, which may make it easier to defend against the aircraft, also known as the F-35 Lightning II.

A terabyte is 1,000 gigabytes.

The officials said similar breaches were recorded at the U.S. Air Force's air traffic-control system in recent months, while the Journal had earlier reported that spies hacked into computers used to manage the U.S. electrical distribution system and other infrastructure.

The latest attacks signal an escalation in attempts by intruders to gain access to vital U.S. security data during the past six months - or at least U.S. awareness of such attacks, a former official said.
