In terms of Skype, the official blog and social networking accounts for Microsoft's VOIP service were hacked, with the group the Syrian Electronic Army (SEA) claiming responsibility. Posts on Skype's blog said “Hacked by Syrian Electronic Army.. Stop Spying!," and “Don’t use Microsoft emails (hotmail,outlook), They are monitoring your accounts and selling the data to the governments."
A pair of tweets credited to the SEA were posted on Skype's official Twitter account. "Stop Spying on People! via Syrian Electronic Army," reads a portion of one of the tweets. And Skype's Facebook page hosted the message: "Don't use Microsoft emails (hotmail,outlook), They are monitoring your accounts and selling it to the governments," with the hashtag "#SEA." As of Thursday morning, anyone going to the Skype blog was redirected to the service's home page.
In the aforementioned tweet, Skype said:
You may have noticed our social media properties were targeted today. No user info was compromised. We’re sorry for the inconvenience.In addition to the blog, the SEA also gained control of Skype’s Facebook and Twitter accounts, although those have since been restored.
The SEA is supposedly run by supporters of Syrian President Bashar Assad. It has taken credit for some high-profile hacks over past months. The messages and posts with regards to Skype come after Edward Snowden's leaks which made quite clear that the NSA is able to eavesdrop on Skype video calls.
