The hacking of Flock Safety's surveillance cameras has exposed the extent of its mass surveillance network, sparking renewed concerns about privacy and public safety. In September 2026, hackers from the activist group stegan0gram physically removed an automated license plate reader (ALPR) camera from Flock Safety and accessed its Android-based system. They created a near-complete copy of the local data, contradicting the company's claims that its devices were protected by end-to-end encryption. By extracting the encryption key directly from the device's storage, the hackers were able to unlock the system and access logs and video streams, revealing the full scope of the surveillance network. Analysis of Flock Safety's software, including its police interface called OS Investigate, showed how the system tracks vehicles and people with high precision. For every vehicle that passes by a camera, the software captures dozens of images—sometimes more than 100—to generate a unique vehicle signature. One camera alone captured 1.6 million images in just 21 days. While Flock claims it does not perform facial recognition, its AI is designed to detect and categorize people, vehicles, and specific details like stickers or patterns. Hackers found that the system had even captured an American flag patch on a motorcyclist's saddlebag. Flock’s software integrates data from its cameras with police records and commercial databases, enabling law enforcement to identify drivers, detect vehicles that frequently travel together, and map out lifestyle habits. This technology has proven highly effective for police, using ALPRs to photograph license plates and AI to analyze vehicle details like brand, color, and even scratches. The system alerts officers to stolen cars or vehicles linked to criminal activity and claims to have aided over a million investigations. However, civil liberties groups argue that this creates a mass surveillance system that records the movements of millions of innocent people, potentially revealing sensitive personal information such as political views or health conditions. Concerns about misuse have been validated by documented cases. The Washington Post found that at least 50 police officers had used the system to track personal relationships, including spouses and ex-partners. In Texas, after the Roe v. Wade decision, deputy sheriffs used Flock to track women suspected of visiting abortion clinics. The Electronic Frontier Foundation also found that over 80 police agencies used racially biased terms to search for vehicles on the national Flock network without any criminal link. Additionally, local police have used the system to share location data with border patrol, violating sanctuary city protections for immigrants. These issues have led to widespread protests and the rise of the DeFlock movement, which uses maps to locate and disable Flock cameras. Over 70 U.S. cities have canceled their contracts with Flock, and some accuse the company of profiting from the resale of anonymized data. In response to public pressure, members of Congress have launched an investigation into Flock Safety's impact on civil liberties. The company's CEO, Garrett Langley, issued an apology for police abuses and implemented changes, such as reducing data retention from 30 to 7 days and requiring valid criminal case numbers for searches. However, privacy advocates argue these measures are not enough to protect citizens' rights. The controversy highlights the ongoing tension between law enforcement needs and the protection of individual privacy in an era of expanding digital surveillance.
