The encrypted passwords of 6.5 million LinkedIn users were posted to a Russian hacker website earlier this month. Although the passwords were encrypted (or "hashed"), the format they were stored in makes them much more vulnerable to cracking. Although the total number of exposed hashes is less than 10 percent of LinkedIn's reported users, security experts recommend LinkedIn users change their passwords as soon as possible.
