How Hackers Are Fighting Back Against ICE

ICE has been invading U.S. cities, targeting, surveilling, harassing, assaulting, detaining, and torturing people who are undocumented immigrants. They also have targeted people with work permits, asylum seekers, permanent residents (people holding “green cards”), naturalized citizens, and even citizens by birth. ICE has spent hundreds of millions of dollars on surveillance technology to spy on anyone—and potentially everyone—in the United States. It can be hard to imagine how to defend oneself against such an overwhelming force. But a few enterprising hackers have started projects to do counter surveillance against ICE, and hopefully protect their communities through clever use of technology. 

Let’s start with Flock, the company behind a number of automated license plate reader (ALPR) and other camera technologies. You might be surprised at how many Flock cameras there are in your community. Many large and small municipalities around the country have signed deals with Flock for license plate readers to track the movement of all cars in their city. Even though these deals are signed by local police departments, oftentimes ICE also gains access. 

Because of their ubiquity, people are interested in finding out where and how many Flock cameras are in their community. One project that can help with this is the OUI-SPY, a small piece of open source hardware. The OUI-SPY runs on a cheap Arduino compatible chip called an ESP-32. There are multiple programs available for loading on the chip, such as “Flock You,” which allows people to detect Flock cameras and “Sky-Spy” to detect overhead drones. There’s also “BLE Detect,” which detects various Bluetooth signals including ones from Axon, Meta’s Ray-Bans that secretly record you, and more. It also has a mode commonly known as “fox hunting” to track down a specific device. Activists and researchers can use this tool to map out different technologies and quantify the spread of surveillance. 

There’s also the open source Wigle app which is primarily designed for mapping out Wi-Fi, but also has the ability to make an audio alert when a specific Wi-Fi or Bluetooth identifier is detected. This means you can set it up to get a notification when it detects products from Flock, Axon, or other nasties in their vicinity. 

One enterprising YouTuber, Benn Jordan, figured out a way to fool Flock cameras into not recording his license plate simply by painting some minor visual noise on his license plate. This is innocuous enough that any human will still be able to read his license plate, but it comp
