A couple weeks ago, Biz explained how Twitter users were being victimized by phishing scams spread primarily through links in Direct Messages. Basically, people click the link and bad things happen. My team can only detect these scams after malicious links have already been sent out.

Today, we’re launching a new service to protect users that strikes a major blow against phishing and other deceitful attacks. By routing all links submitted to Twitter through this new service, we can detect, intercept, and prevent the spread of bad links across all of Twitter. Even if a bad link is already sent out in an email notification and somebody clicks on it, we'll be able keep that user safe.

A much needed step.
