The TRA (Telecom Regulatory Authority) decides what internet censorship policy is in the UAE, not the telecom companies Etisalat and Du, although many residents will feel that Etisalat in particular is the decider of what is and is not allowed.
Koobface originally spread by delivering Facebook messages to people who are "friends" of a Facebook user whose computer had already been infected.
Koobface is a network worm that attacks Microsoft Windows Version 7-8-10 , Apple Mac OS X (All Version) IPAD - IPOD - IPAD MINI APPLE TV SMART TV , and Linux platforms. This worm originally targeted users of networking websites like Facebook, Skype, Instagram Watsapp Yahoo Messenger, and email websites such as GMail, Yahoo Mail, and AOL Mail Comcast At&T ECT.
It also targets other networking websites, such as My Space, Twitter, and it can infect other devices on the same local network in the house or Office.
The TRA has said in 20 that these areas will have to come under the UAE censorship policy though.
For the most part, internet censorship is not overly draconian in the UAE.
