Blogging site Twitter has been targeted by cyber criminals with programs capable of stealing data disguised as downloads.


A fake profile was spotted by security firm Kaspersky where a link was offered to a pornographic video, though upon linking a fake version of Adobe Flash was downloaded which installed data stealing programs. Following worms hitting the Facebook and Myspace social networks recently, it is thought that this the first time Twitter has been attacked.


It is believed that the attack originated in Brazil because of the language used, the servers called on to download Trojans and the email address used to collect stolen data.


The fake profile has a name that is Portuguese for ‘pretty rabbit' and it tries to convince users to download the fake Flash video viewer to watch the associated video.


Alexander Gostev, a senior virus analyst at Kaspersky Lab, told the BBC: “Unfortunately users are very trusting of messages left by friends on social networking sites so the likelihood of a user clicking on a link like this is very high. Only those using Microsoft Windows are vulnerable to infection from these malicious programs.”
