Hacker posts fake New York Times editorial

The editorial, titled "WikiLeaks, a Post Postscript," was purportedly published over the weekend by the Times and in every way appears to be the real thing from Keller, who until last September was the paper's executive editor.

It was so realistic that none other than the newspaper's technology editor Nick Bilton posted the link on his Twitter account, calling the apparent defense of Julian Assange's controversial organization an "important piece."

Not so.

"THERE IS A FAKE OP-ED GOING AROUND UNDER MY NAME, ABOUT WIKILEAKS. EMPHASIS ON 'FAKE.' AS IN, NOT MINE," Keller, now a writer on the paper, tweeted to set the record straight.

Bilton followed up, tweeting: "I just deleted a tweet sent late last night that was from a fake NYT Bill Keller account."

One of the few clues to the forgery was the web address of http://www.opinion-nytimes.com/2012/07/29/opinion/keller-a-post-postscript.html,since the real website's URL begins with www.nytimes.com.
