The Syrian e-army attacked a blog and a Skype account at Skype, where a call was placed to stop using Microsoft email services (hotmail, outlook), according to hackers, monitoring its contents of user accounts and transferring all the information of interest to US authorities. At the moment there is no statement of the company about the incident, as well as information about whether the attackers managed to get access to any user data or other Skype services.
At the time of this writing, the messages from the blog have already been deleted, but Skype has not yet returned control of Skype, since the messages still remain there.

UPD: Skype regained control of her Twitter account, where she apologized for the inconvenience and assured that no user data had been compromised.
The blog appears to have been disabled to investigate the incident. When you try to access it, it redirects to the main Skype page.
