Okay, my English must be rusty. I always thought the proper spelling was 
"i-n-g-e-n-U-o-u-s".

The fun actually continues in next paragraph:
===
One security expert familiar with the investigation wondered how the 
hackers could have known to breach security by focusing on the 
vulnerability in the browser. “It would have been hard to prepare for this 
type of vulnerability,” he said. The security expert insisted on anonymity 
because the inquiry was at an early stage. 
===

The quoted sentence contains an extra "for"; unless there is something 
more behind the scenes, it's probably the most obvious attack vector one 
can think of.
