Syrian Electronic Army hackers also compromised Skype’s Facebook page and a company blog hosted on Skype’s website. Attack appears to be linked to documents released by Edward Snowden, which revealed the PRISM surveillance program. Skype regained the access to their accounts and deleted all fake messages posted by hackers, “You may have noticed our social media properties were targeted today. No user info was compromised,” a statement from Skype said from Skype. Skype and Microsoft have been cooperating with the government. NSA reportedly can see data about online conversations from other Internet behemoths too, including Verizon, AT&T, Google and Facebook.
