Covert?

The lead story on the NYTimes homepage right now is:
Obama Widens Missile Strikes Inside Pakistan

And here's the first paragraph:

WASHINGTON — With two missile strikes over the past week, the Obama administration has expanded the covert war run by the Central Intelligence Agency inside Pakistan, attacking a militant network seeking to topple the Pakistani government.

Not very covert now, is it? What does covert mean? Well, the NYT's annoying question-mark pop-up came in handy here. According to them, it's:
"Not openly practiced, avowed, engaged in, accumulated, or shown"

So something on the cover of the NYT is not openly practiced, avowed, engaged in, accumulated, or shown?
