Announcing Scumblr and Sketchy - Search, Screenshot, and Reclaim the Internet
Netflix is pleased to announce the open source release of two security-related web applications: Scumblr and Sketchy!

Many security teams need to stay on the lookout for Internet-based discussions, posts, and other bits that may be of impact to the organizations they are protecting. These teams then take a variety of actions based on the nature of the findings discovered. Netflix’s security team has these same requirements, and today we’re releasing some of the tools that help us in these efforts.


Scumblr is a Ruby on Rails web application that allows searching the Internet for sites and content of interest. Scumblr includes a set of built-in libraries that allow creating searches for common sites like Google, Facebook, and Twitter. For other sites, it is easy to create plugins to perform targeted searches and return results. Once you have Scumblr setup, you can run the searches manually or automatically on a recurring basis.

One of the features we wanted to see in Scumblr was the ability to collect screenshots and text content from potentially malicious sites - this allows security analysts to preview Scumblr results without the risk of visiting the site directly. We wanted this collection system to be isolated from Scumblr and also resilient to sites that may perform malicious actions. We also decided it would be nice to build an API that we could use in other applications outside of Scumblr. Although a variety of tools and frameworks exist for taking screenshots, we discovered a number of edge cases that made taking reliable screenshots difficult - capturing screenshots from AJAX-heavy sites, cut-off images with virtual X drivers, and SSL and compression issues in the PhantomJS driver for Selenium, to name a few. In order to solve these challenges, we decided to leverage the best possible tools and create an API framework that would allow for reliable, scalable, and easy to use screenshot and text scraping capabilities. Sketchy to the rescue!
