Hackers Got Inside a Flock Camera. Its Data Shows How the System Works

do the articles have significantly different information/coverage to warrant two submissions?

20m agoHN ↗

I can't read the Wired article because I'm only allowed three excerpts and 15 ads a day at Wired.com

10m agoHN ↗

same, but i'm not sure how that's related to my comment. workarounds or alternate articles without significant new information are typically posted within the same submission, not separate ones.

I poked around in the boot partition. The kernel is ancient!

Linux version 3.18.71-perf-gaf770dc

37m agoHN ↗

The oldest supported kernel is 5.10 and that loses support in December. That's wild they are using a 3.X kernel

1h agoHN ↗

so when do we get it flipped to a nationwide bird migration tracking system?

as someone pointed out: let's make that "flock" name accurate

also make it identify bird song, I am sure there are microphones on there

28m agoHN ↗

Someone should sell branded black trashbags with a spraypainted penis on them.

We'll call it Cock Safety and help our community with patented JimmyHat technology to keep you safe and covered.

50m agoHN ↗

At the same time, about every two minutes, code checked that the camera was still running and logged the message, “Who’s a good boy?!

48m agoHN ↗

I think I should start posting a reminder in Flock threads that Axon is a Flock competitor, is also engaged in mass surveillance, and is possibly even worse, but there’s rarely any mention of it. Journalists need to do some digging there. This shouldn’t just be a Flock story, or Flock will just get bought up or something and everyone will move on.

(The above should not be read as supporting Flock or discouraging further investigation.)

The camera’s logs also show the camera struggling with storage. Its logs recorded more than 27,000 “no space left on device” errors while trying to save full-resolution images, along with tens of thousands of related errors, crashes, and reboots. At the same time, about every two minutes, code checked that the camera was still running and logged the message, “Who’s a good boy?!” More than 12,000 of those messages appear in the recovered logs.

Lol

44m agoHN ↗

"Axon is Flock but worse" will be the next big fight as police departments are pulling a fast one and saying "we got rid of Flock" by switching to Axon.

37m agoHN ↗

Axon is the default for the on-body camera system. The barrage of cop tv shows use them as part of their promotional relationships. Flock decided to not attack their market, in stead go for the adjacent space.

30m agoHN ↗

While highly unprofessional, the "Who's a good boy?!" status message makes me like them a tiny bit more

11m agoHN ↗

For those unaware, embedded devices usually have a "watchdog" timer that needs to be periodically reset ("fed"/"pet"/"kicked") when everything is operating correctly or else the device will reboot as a fail-safe.

This log message probably indicates when they're resetting the watchdog timer.

21m agoHN ↗

While Axon's system should be under the microscope too I don't think they have the nation wide cloud that Flock is doing and requires specific agreements to share data. Maybe that is getting abused to form a national database but I imagine it was designed so say a county sheriff department and local city PDs could share resources. I don't think most people are that concerned about things like that (though they should be), it is the nation wide surveillance that creeps people out. That and the stalking of course and both systems can be used for that.

18m agoHN ↗

Also, a reminder that ALPR abuse predates Flock. Flock has just made it more visible. About a decade ago I personally heard a cop let it slip that he had plate-stalked someone for the crime of saying mean things about his department on Twitter. The difference today is that more departments have access to these kinds of tools.

Fixed ALPRs aren't the only privacy problem, either. Many tow trucks have roving ALPRs that feed into big databases. The notion is that it helps them repossess cars that might be garaged at home. That data, however, is for sale to third parties.

45m agoHN ↗

So… all that data is literally there for any unauthorized person to walk up and take it.

It’s not even suitably encrypted on device?

Zero trust in anything Flock says.

31m agoHN ↗

It is bad.

But think the real danger in Flock is the aggregate data, tracking between camaras. So if someone hacks a single camara, they probably don't get much, unless it is pointed right at someone, which is bad. Aren't they selling these as should be pointing at traffic? If they are pointing right at people, like at playgrounds, then they are being installed illegally to begin with ?

29m agoHN ↗

Is this an older model? I could see them turning off or using weak encryption on media if the hardware couldn't keep up with the amount of data they were writing.

19m agoHN ↗

I'm in the process of optimizing a bootolader for my various SoC/SBCs and even the cheapest, oldest least powerful SoC from 15 years ago can manage AES-CBC via crypto accelerator at 50 MiB/s. There's no excuse.

5m agoHN ↗

Yep. Clown show.

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—think, the videos and stills—the camera took.

In early 2025, security researcher Jon “GainSec” Gaines reverse engineered a Flock license-plate reader and documented flaws that could be used to gain root-level access. After Gaines disclosed his findings, the company acknowledged the findings but downplayed their severity, writing that the flaws required physical access to the device and that even someone who gained access to a camera “would still not be able to gain access to footage” because images remained on the device only briefly after being transmitted to the cloud.

Why did we not get the cool dystopia ala Gibson's Chiba City?

23m agoHN ↗

Because we got the gray box IBM version instead...

23m agoHN ↗

Correct. YC gotta wear their creations with pride.

17m agoHN ↗

I feel like most of this was already known when someone here in Dallas figured out they had wifi connectivity you could connect and get access. I may not have the details exactly correct but I think someone got access then.

16m agoHN ↗

Flock is a scourge on democracy. Flock is YC. But looks like they did YC nearly ten years ago. Who knows what their pitch deck looked like? If they pivoted since then to their current sinister incarnation? I don’t see any evidence that YC is still actively supporting them.

Benefit of the doubt: Funding them for a community/city-owned traffic camera type thing seems like it would have been a much more reasonable proposition than funding Flock for their current use case of allowing police to stalk their ex girlfriends or mistresses.

9m agoHN ↗

Don't have the pitch deck directly, but do have some of the "what things looked like then" at https://www.ycdb.co/company/flock-safety

The front page then had "All the footage is yours. Your neighborhood 100% owns the data. Flock Safety will not share, sell, or access your data."

Unfortunately, flock has been excluded from wayback, so can't see other views of that page.

{insert Darth Vader: I'm altering the deal. Pray I don't alter it any further.}

9m agoHN ↗

They just had a Superbowl ad like two years ago (ok, it was for Ring, but partnering with Flock) that said it was all about finding lost dogs around the neighborhood...and, that was it.

Is hacker news anti-dog now ?

6m agoHN ↗

It’s not like this stuff wasn’t known to be a problem 10 years ago. We were already in Trump’s first term, it’s not like it was part of the early post 9/11 “secure everything” push. It was WAY after that.

10 years ago is no excuse.

12m agoHN ↗

If I had to guess now it works it would be:

1. Take pictures

2. Send to a big server that all cops nationwide can log into whenever they want to stalk their exes

Did I miss something

10m agoHN ↗

According to our analysis, the camera’s logs recorded about 21 days of activity across several periods. During those windows, the device photographed roughly 50,200 vehicles and generated about 1.6 million images. On a typical day, it logged around 3,300 vehicles, with a high of 4,454.

Has there been any report about which state this camera was recovered in? New Hampshire has a strict 3 minute rule for non-hit plate data before the captured images and records must be deleted [1].

[1] (N.H. Rev. Stat. § 261:75-b) requires ALPR systems to delete non-hit plate data within 3 minutes

A friend in China built a Flock overlay network that sends live video and audio from ~100 cameras near me to an AWS server for processing and search.

"We liberated hardware"

Ya know, I'm not on Flock's side here.. but be real, this is theft. You should be able to own that if you're going to do something like this.

5m agoHN ↗

And my privacy? The threat to democracy? Does Flock own that? Why is always the poors that need to own morality?
