If you’ve received a weird message on Skype with a link to Baidu or LinkedIn recently, you’re not alone. In the past couple of weeks, I’ve received spam links to Baidu from six of my Skype contacts, one of whom works for Microsoft’s PR agency and another is a former Microsoft employee. All were surprised to see their accounts breached, and some believed they were protected by Microsoft’s two-factor authentication. That wasn’t the case, though.
