As Director of Twitter’s Trust and Safety team, a big part of my job is focused on the detection and prevention of spam and abuse. 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.
Since these attacks occur primarily on Direct Messages and email notifications about Direct Messages, this is where we have focused our initial efforts. For the most part, you will not notice this feature because it works behind the scenes but you may notice links shortened to twt.tl in Direct Messages and email notifications. Special thanks to @wfarner and @ram for building this service and helping keep us all a little safer!
