A group of computer hackers on Sunday posted a document it claimed contains usernames and passwords for an Apple Inc. server, the latest in a string of brazen attacks that have compromised government and corporate websites around the world.

"AntiSec," a hacking campaign that includes hackers from both the online vigilante group Anonymous and hackers from the now-defunct Lulz Security, posted a document containing a link to a supposed Apple server along with a list of 26 administrative usernames and passwords. AntiSec is Internet shorthand for "anti-security."

The hackers said in a statement posted to Twitter that they had accessed Apple's systems due to a security flaw used in software used by the Cupertino, Calif.-based gadget maker and other companies. "But don't worry," the hackers said, "we are busy elsewhere."

A spokesman for Apple didn't immediately respond to a request for comment.

The posted information comes as part of a two-month campaign of digital heists targeting corporations including Sony Corp. and AT&T Inc., as well as government agencies such as the U.S. Senate, the Central Intelligence Agency and the Arizona Department of Public Safety.
