…this time against the White House’s computers.

White House sources partly confirmed an alarming report that US government computers were breached by Chinese hackers.

“This was a spear phishing attack against an unclassified network,” a White House official told FoxNews.com.

Spear phishing consists of attempts directed at specific individuals.  Sure enough, “This [White House Communications Agency] guy opened an email he wasn’t supposed to open,” according to a law enforcement official investigating the attack.

Most likely, this was a preliminary, probing attack, in preparation for a later, more fully developed assault.  Or a demonstration of things to come if we don’t step back.

Sure enough,

[a] White House official downplayed that report, saying that the system involved was not a sensitive nuclear system, and no evidence indicated that information was actually taken.

That’s OK, then.  The fact of the successful probe is itself no big deal.  Sure.
