Twitter shields up with an extra layer of Security

With their t.co domain, any posted URL in twitter will be shielded with this domain. Basically the shortened link of t.co will redirect to the URL giving twitter folks a door to process the link.

This way twitter can track and run security checks on all links on twitter. In case of any malicious links, Twitter can easily delete the reference and protect twitter users.

Of course this created an extra work for 3rd party twitter clients, and URL shorten services like twitlonger, in particular. Clients should now unpack the t.co to get the original URL before processing links.

As I wrote in a previous post added security decrease performance most of the time.
