Half the people I know were scrambling to change their passwords after the report that millions of LinkedIn passwords had been leaked on a hacker web site recently. Many found themselves having to reset passwords on dozens of social sites, because they use the same password for all of them (a major security "no-no").
So what's being done about it? LinkedIn reports that they have disabled all the accounts that were affected and are increasing security to prevent it from happening again. They have hired outside forensics experts and the FBI is investigating the breach. Customers whose passwords were stolen have been notified.
