Surveillance Camera Security? It’s Completely Flocked!

September 17, 2026 by Jenny List 61 Comments

Surveillance cameras from Flock Safety have become a controversial privacy battleground, as the communities in which they are installed wake up to their sinister potential, and stories roll in of law enforcement professionals abusing their access. One has had its disk contents dumped, and we’ve been treated to some insights courtesy of [Micah Lee]. In short: their approach to security is deeply flawed.

It’s interesting to find that instead of a custom hardened OS, these devices run Android. Not just Android, but Android 8.1, a long out of support version originally released in 2017. This is is the year Flock Safety was founded, which may or may not be coincidental. Like any old version of a widely used operating system it has a host of known vulnerabilities, none of which are patched on this version.

The Android version is small beer compared to the revelation that they contain a hard-coded and very open-access API key that can be used by any mildly curious miscreant to reveal information from any Flock camera using its MAC address. One would hope that a product marketed for use by law enforcement might have paid attention to such a basic lapse, but it seems not. Whether or not this can be corrected by a software upgrade and the leaked key deactivated without turning off the network depends on whether thy can do upgrades tailored to specific devices, but either way we wouldn’t like to be the team tasked with fixing that one.

In a way it’s reassuring that the surveillance apparatus when it came was so incompetently managed, and we hope that these vulnerabilities will have moderated its effect. We’re sure more tasty discoveries will emerge as investigations proceed, and we’ve got the popcorn ready.

Hackaday Links: February 15, 2026

It probably won’t come as much of a surprise to find that most of the Hackaday staff aren’t exactly what you’d call sports fanatics, so we won’t judge if you didn’t tune in for the Super Bowl last week. But if you did, perhaps you noticed Ring’s Orwellian “Search Party” spot — the company was hoping to get customers excited about a new feature that allows them to upload a picture of their missing pet and have Ring cameras all over the neighborhood search for a visual match. Unfortunately for Ring, the response on social media wasn’t quite what they expected.

One commenter on YouTube summed it up nicely: “This is like the commercial they show at the beginning of a dystopian sci-fi film to quickly show people how bad things have gotten.” You don’t have to be some privacy expert to see how this sort of mass surveillance is a slippery slope. Many were left wondering just who or what the new system would be searching for when it wasn’t busy sniffing out lost pups.

The folks at Wyze were quick to capitalize on the misstep, releasing their own parody ad a few days later that showed various three-letter agencies leaving rave reviews for the new feature. By Thursday, Ring announced they would be canceling a planned expansion that would have given the divisive Flock Safety access to their network of cameras. We’re sure it was just a coincidence.

Speaking of three-letter agencies, the Environmental Protection Agency has announced this week that they will no longer incentivize the inclusion of stop-start systems on new automobiles. The feature, which shuts off the engine when the vehicle comes to a stop, was never actually required by federal law; rather, the EPA previously awarded credits to automakers that added the feature, which would help them meet overall emission standards. Manufacturers are free to continue offering stop-start systems on their cars if they wish, but without the EPA credits, there’s little benefit in doing so. Especially since, as Car and Driver notes, it seems like most manufacturers are happy to be rid of it. The feature has long been controversial with drivers as well, to the point that we’ve seen DIY methods to shut it off.

Hackaday Links: October 19, 2025

After a quiet week in the news cycle, surveillance concern Flock jumped right back in with both feet, announcing a strategic partnership with Amazon’s Ring to integrate that company’s network of doorbell cameras into one all-seeing digital panopticon. Previously, we’d covered both Flock’s “UAVs as a service” model for combating retail theft from above, as well as the somewhat grassroots effort to fight back at the company’s wide-ranging network of license plate reader cameras. The Ring deal is not quite as “in your face” as drones chasing shoplifters, but it’s perhaps a bit more alarming, as it gives U.S. law enforcement agencies easy access to the Ring Community Request program directly through the Flock software that they (probably) already use.

Spy Tech: Build Your Own Laser Eavesdropper

March 18, 2025 by Heidi Ulrich 35 Comments

Laser microphones have been around since the Cold War. Back in those days, they were a favorite tool of the KGB – allowing spies to listen in on what was being said in a room from a safe distance. This project by [SomethingAbtScience] resurrects that concept with a DIY build that any hacker worth their soldering iron can whip up on a modest budget. And let’s face it, few things are cooler than turning a distant window into a microphone.

At its core this hack shines a laser on a window, detects the reflected light, and picks up subtle vibrations caused by conversations inside the room. [SomethingAbtScience] uses an ordinary red laser (visible, because YouTube rules) and repurposes an amplifier circuit ripped from an old mic, swapping the capsule for a photodiode. The build is elegant in its simplicity, but what really makes it shine is the attention to detail: adding a polarizing filter to cut ambient noise and 3D printing a stabilized sensor mount. The output is still a bit noisy, but with some fine tuning – and perhaps a second sensor for differential analysis – there’s potential for crystal-clear audio reconstruction. Just don’t expect it to pass MI6 quality control.

While you probably won’t be spying on diplomats anytime soon, this project is a fascinating glimpse into a bygone era of physical surveillance. It’s also a reminder of how much can be accomplished with a laser pointer, some ingenuity, and the curiosity to see how far a signal can travel.

Supercon 2023: Alex Lynd Explores MCUs In Infosec

April 24, 2024 by Tom Nardi 9 Comments

The average Hackaday reader hardly needs to be reminded of the incredible potential of the modern microcontroller. While the Arduino was certainly transformative when it hit the scene, those early 8-bit MCUs were nothing compared to what’s on the market now. Multiple cores with clock speeds measured in the hundreds of megahertz, several MB of flash storage, and of course integrated WiFi capability mean today’s chips are much closer to being fully-fledged computers than their predecessors.

It’s not hard to see the impact this has had on the electronics hobby. In the early 2000s, getting your hardware project connected to the Internet was a major accomplishment that probably involved bringing some hacked home router along for the ride. But today, most would consider something like an Internet-connected remote environmental monitor to be a good starter project. Just plug in a couple I2C sensors, write a few lines of Python, and you’ve got live data pouring into a web interface that you can view on your mobile device — all for just a few bucks worth of hardware.

But just because we’re keenly aware of the benefits and capabilities of microcontrollers like the ESP32 or the Pi Pico, doesn’t mean they’ve made the same impact in other tech circles. In his talk Wireless Hacking on a $5 Budget, Alex Lynd goes over some examples of how he’s personally put these devices to work as part of his information security (infosec) research.

We all know that we’re living in a surveillance state that would make Orwell himself shake his head, but it looks like at least one company in this space has gone a little rogue. According to reports, AI surveillance start-up Flock <<insert gratuitous “What the Flock?” joke here>> has installed at least 200 of its car-tracking cameras on public roads in South Carolina alone. That’s a serious whoopsie, especially since it’s illegal to install anything on state infrastructure without permission, which it appears Flock failed to obtain. South Carolina authorities are making a good show of being outraged about this, but it sort of rings hollow to us, especially since Flock now claims that 70% of the population (of the USA, we presume) is covered by their technology. Also, police departments across the country are in love with Flock’s service, which lets them accurately track the movements of potential suspects, which of course is everyone. No word on whether Flock will have to remove the rogue cameras, but we’re not holding our breath.

Big Candy Is Watching You: Facial Recognition In Vending Machines Upsets University

February 27, 2024 by Maya Posch 50 Comments

Most people don’t think too much of vending machines. They’re just those hulking machines that lurk around on train stations, airports and in the bowels of school and office buildings, where you can exchange far too much money for a drink or a snack. What few people are aware of is just how these vending machines have changed over the decades, to the point where they’re now collecting any shred of information on who interacts with them, down to their age and gender.

How do we know this? We have a few enterprising students at the University of Waterloo to thank. After [SquidKid47] posted a troubling error message displayed by a campus M&M vending machine on Reddit, [River Stanley] decided to investigate the situation. The resulting article was published in the February 16th edition of the university’s digital newspaper, mathNEWS.

In a bout of what the publication refers to as “Actual Journalism”, [Stanley] found that the machine in question was produced by Invenda, who in their brochure (PDF) excitedly note the many ways in which statistics like age, gender, foot traffic, session time and product demographics can be collected. This data, which includes the feed from an always-on camera, is then processed and ‘anonymized statistics’ are sent to central servers for perusal by the vending machine owner.

The good news is that this probably doesn’t mean that facial recognition and similar personalized information is stored (or sent to the big vaporous mainframe) as this would violate the GDPR and similar data privacy laws, but there is precedence of information kiosks at a mall operator taking more liberties. Although the University of Waterloo has said that these particular vending machines will be removed, there’s something uncomfortable about knowing that those previously benign vending machines are now increasingly more like the telescreens in Orwell’s Nineteen Eighty-Four. Perhaps we’re already at the point in this timeline were it’s best to assume that even vending machines are always watching and listening, to learn our most intimate snacking and drinking habits.

Thanks to [Albert Hall] for the tip.
