LinkedIn provides breach update -- sort of

Jaikumar Vijayan | June 8, 2012
In an update that raises more questions than it answers, LinkedIn today assured members that the company is working hard to protect their personal data in the wake of a security breach that exposed about 6.5 million hashed LinkedIn passwords.

"The only way to salt an existing hash is to recalculate the hash after a user logs in, or for the users to have all changed their passwords," Wisniewski said.

Silveira's comments about only a few hashed passwords being decoded and published are also puzzling, he said. "Why they believe only a small percentage have been solved is confusing. While only a small percentage have been published, most all of them have been discovered, according to many sources who have been trying to crack them," he said.
