It is true to say that most of the attacks on the accounts Twitter is because unsuspecting users click malicious links (often short because of the very restriction of 140 characters) and, in one way or another, put the control of their profiles in the hands of hackers. Del Harvey, Twitter security director, ensures that from now this kind of problem with short links will become scarce.
According to Harvey, the service microblog yesterday launched a system that detects, intercepts and prevents phishing attacks is propagem through shortened links. Primarily only links sent by direct message (DM), the main source of this type of attack, pass through this system, which will not be seen by the user.
Some of these links will be shortened using own shortener Twitter URLs, twt.tl, which is also not available for public use in general. If the link is detected as malicious, users who click will be redirected to a page warning of the threat. The other URLs posted on the site, excluding short links, already undergo an anti-phishing filter (the same used by Google) that prevents the publication of websites that contain viruses and other malicious programs.
