“Why just destroy them when we can reverse engineer them and find the secrets of those spying on us?” one of the hackers, from a collective calling itself stegan0gram, said in an interview. “We liberated hardware in the field, disarmed them, and proceeded with reverse engineering of the cameras and associated solar equipment.”
Flock’s cameras photograph passing vehicles and send the images and other data to the company’s servers. There, Flock’s system presumably reads the license plate and can identify characteristics, such as the vehicle’s color, make, and model. Flock then makes these time-stamped records searchable by whichever local agency owns or has access to the cameras. But in many cases, Flock’s system also allows other police departments from all over the country to search those cameras as part of the company’s national network. In Alpharetta, Georgia, for example, WIRED found that records from the city’s Flock cameras were accessible to more than 2,000 agencies, including police departments, colleges, airports, and, inexplicably, the Office of Inspector General for the federal General Services Administration.
This national network has been a selling point for Flock but also a deep source of controversy. 404 Media revealed that local cops were performing lookups in the national network on behalf of Immigration and Customs Enforcement, including in areas that banned working with immigration authorities or transferring license plate data out of state. 404 Media also revealed that a cop in Texas searched Flock cameras nationwide for a woman who self-administered an abortion. Those stories, among others, triggered a national conversation about whether people want Flock cameras, or automatic license plate readers more generally, in their communities.
And in the case of stegan0gram, the answer is clearly no.
The hackers said they were able to access the Android system on the camera and found two partitions—sections of its hard drive, essentially. A few of these were unencrypted, the hackers said, including one called “vendor” and another called “media.” The latter contained an encryption key that unlocked another part, which contained much of the media—the videos and stills—the camera took.
