AppNexus expends significant resources – technical, financial, and human – to protect publishers, advertisers, and consumers from the many potential negative impacts of the complex online advertising ecosystem. The extraordinary scale of deployed third-party widgets, including advertising tags, attracts bad actors to the advertising space to find ways to manipulate this ecosystem for profit. Our obligation at AppNexus is not just to prevent these issues for AppNexus clients, but to make sure that we protect consumers and the broader Internet ecosystem from bad actors. At its core, our mission is to create a better Internet, and consumer protection is at the heart of what we do.
AppNexus engineers quickly identified the potential problem and began patching the vulnerability. At 4 PM on March 4th, last Friday, we rolled out a patch globally that resolved the issue on the AppNexus platform. You can read more about the details to our fix here.
In summary, I believe that Randy's blog post was a timely wake-up call for all of us who spend our lives and make our livelihood on the Internet. It's not going to be easy, but it's our shared responsibility to create a better Internet – together.
