Here is the official notice on skype heartbeat: http://heartbeat.skype.com/2015/09/skype_presence_issues.htm...

Microsoft applied another NSA patch without properly testing it first?! :)))

I've recently saw and article from a guy who did memory dump of Skype and found his SSH keys inside. This is getting out of control...
