Nicole Richie recently hacked the Twitter accounts of Kim Kardashian and Joel Madden "as part of a prank that proves just about anyone can become a password hacker," according to The Register's John Leyden.

"Kardashian, who received some strange email via her BlackBerry as a result of the prank, subsequently posted a message on her blog letting interested parties know the two accounts had been hacked by Nicole Richie as part of an April Fool's joke," Leyden writes. "Richie had the help of Kardashian's sister Khloe in obtaining the password for her sibling's Twitter account."

"More on the prank, including a list of the fake tweets, can be found in a blog entry by Sophos here," Leyden notes.
