The Google search engine blocked access to the sites of the group Black Shadow,” the justice said ministry said, a move it said was taken at the request of the government’s Cyber Unit.

Messaging application Telegram had also suppressed Black Shadow groups, it added.

The announcement came hours after Black Shadow dumped a large file online, that was said to contain as many as a million users of the Atraf dating site.

Black Shadow had already released a batch of Atraf user profiles over the weekend, and on Sunday demanded $1 million within 48 hours to prevent the wider leak.
