Hi, xxx! A new twitter service! Try it, nice one! http://twltter.ru/
Don’t click the link! I clicked and it’s exactly identical to twitter’s own interface. I thought it was twitter so I entered my username/password, but nothing happened. After a few hours I realize this might be a malicious website. So I changed my twitter password.
Social networks make us more connected — but also more vulnerable for virus to spread. Be careful.
