 Hello, You may not yet be familiar with ShadowDragon's SocialNet tool, but it could be familiar with you. A new investigation from 404 Media claims that ShadowDragon, a contractor for the U.S. government, is scraping data from over 200 widely-used websites — including Reddit, Etsy, Glassdoor, Tinder, and Duolingo. That data is then funnelled into a sophisticated surveillance system used by U.S. government agencies, like Immigration and Customs Enforcement (ICE).1 Even if you’re outside the United States, this matters to you, too — and here’s why. The rise of mass online surveillance tools extends beyond borders, sending shockwaves that can influence countries around the globe. ShadowDragon’s surveillance technology sets a perilous precedent — one that could embolden governments everywhere to adopt similar invasive methods. SocialNet pulls information from job boards, social networks, rental listings, and even messaging platforms to build invasive digital profiles — often without the platforms’ knowledge or consent. Thanks to 404 Media’s investigation, we now know exactly which sites are being exploited. Now it’s up to us to pressure these websites and services to block surveillance tools like SocialNet and strengthen their privacy protections. That’s why Mozilla is launching an urgent campaign targeting 30 critical and widely-used websites and services, calling on them to immediately block access to ShadowDragon’s tools.2 Add your name now to demand that these 30 companies — including Reddit, Etsy, Glassdoor, Tinder, and Duolingo — do everything in their power to safeguard our data. Right now it’s up to us to stop shady surveillance tools like ShadowDragon’s SocialNet, increase transparency, and strengthen privacy protections. SocialNet doesn’t simply track your online activity; it combines information about your identity, location, relationships, and even your political views. While no single platform discloses everything about you, the mosaic of data from hundreds of sites makes it easy to profile and target individuals. This is not a distant concern; it’s a reality unfolding before our eyes. Immigration enforcement agencies are using tools like SocialNet to locate, target, and deport individuals within the United States. They couldn’t do it without surveillance tech like SocialNet.3 These shady tech tools make mass targeting fast, scalable, and invisible. It’s not only immigrants who are at risk. These tools can just as easily be used to monitor protestors, researchers, journalists, and human rights defenders — anyone who challenges power. Each of the companies targeted by Mozilla in this campaign has a responsibility to protect user data. Internet users deserve better from the websites and services we rely on every day. We believe that if enough of us come together, we can pressure them to act to block surveillance tools like SocialNet. Because Mozilla is a movement of people like you — people who believe that privacy and transparency are fundamental to our digital rights. This is our data, our conversations, our communities. Together, we won’t stand by while they’re exploited. Add your name now to demand intermediate action and real accountability from these 30 websites and services putting our privacy at risk. Stay tuned as we roll out more ways to pressure these 30 critical websites and services to safeguard our data from unscrupulous surveillance firms. Thank you for everything you do for the internet.
