That message was an apparent reference to revelations last year by former National Security Agency contractor Edward Snowden that Skype, which is owned by Microsoft, was part of the NSA’s program to monitor communications through some of the biggest US internet companies.
A message posted on Skype’s official Twitter feed, apparently by the hacking group, read: “Don’t use Microsoft emails (hotmail, outlook), They are monitoring your accounts and selling the data to the governments. More details soon. #SEA”
Similar messages were posted on Skype’s official Facebook pages and on a blog on its website before being taken down in late afternoon. The SEA later tweeted out copies of the message “for those who missed it.”
