Hackers found Flock cameras can track more than just cars — and Boston officials found camera data was shared despite being told it wouldn’t be

Boston officials released a report explaining why they won't use Flock cameras It reveals that Flock shared camera data despite saying it wouldn't Hackers also discovered that Flock cameras track more than just license plates The Flock backlash might have taken a backseat to more recent tech news — namely, whether AI development needs to slow down before superintelligence wipes us out, or, on a lighter note, Apple’s first foldable iPhone — but the anti-surveillance crusade is continuing, with Boston officials and its police department announcing the city will not be relying on the service any longer.

This follows the publishing of a 2025 report which included details on a Flock pilot the city ran in 2025.

According to the report, the city discovered Flock was sharing data with external law enforcement agencies — despite Flock’s agreement with Boston saying data sharing was to be turned off, and the company confirming this was the case.

In response, city officials and Boston's police department have committed to no longer using Flock cameras going forward.

However, it’s worth noting this is not an absolute win for privacy advocates.

Boston police department has already begun pilots with two of Flock's rivals: a Motorola trial began back in February, while an Axon pilot began in June, suggesting it might merely move to a different Automatic License Plate Recognition (ALPR) service.

Analyzing encrypted data, hackers found the cameras also detect people and bicycles — and they can also pick up and isolate specific bumper stickers.

The fact that the cameras are able to pick up and monitor so much more than some may have realized is worrying enough, but what’s extra concerning is that this data was recovered from a physical camera.

Hopefully Flock will solve this soon, but currently it means anyone with the right hacking skills could tear down a camera and access a chunk of the data stored inside the device — meaning you might not just need to worry about what officials can do with your data (Image credit: Getty Images) Is there a right way to use ALPR? For many, the answer to the question of if there’s a right way to use Flock or similar cameras is an emphatic no, but for advocates of the tech, there are sensible measures police departments could be using to minimize abuse.

Limiting automatic sharing of data to other agencies and restricting the police officers with access are a good starting point.

They also argue that all Flock data requests should require case numbers to be attached, and for officers to provide a reason for each request.
