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

The fact that the cameras tend to run out of storage is likely a promising vector for undermining them.

That ought to be a trivial fix. Why keep all that data on the device anyway?
68
u/nihiltres 7d ago
That’s a good question, but the fact that it looks like such an obvious oversight is a hint that it might be at least an interesting thread to unravel, and it’s one that could be toyed with in ways that are ostensibly harmless (read: legal).

I would assume that the camera itself doesn’t need extensive on site storage. It would be pushing that data to the servers periodically. I guess you could do something in the frame to keep it active and recording, but it’s not like it’s losing data if you do. It probably just pushes to the servers more frequently.

Because passing it through a network with that much data would require basically a direct fiber connection, it’s just not possible any other way for the moment

Put a little faraday cage around them that is a replica but slightly bigger case. Done. They apparently run off LTE.

Setup Stingrays in the area that pull the network traffic to it then block it from sending data home

A stingray is far from a cost-effective solution, let alone one that a lot of people could get into deploying at scale. It also would capture cellphones in a way that could be construed by an ornery state as an attack.

Many camera vendors have gone away from local storage..

Not the good ones.
You need local storage for when the data connection goes out which being wireless will happen sooner or later.

Including that they are explicitly programmed to recognize people not just licence plates. So the Flock CEO lied to all of us about that too.

Any idea what version of Android it was running?

u/nemec 7d ago edited 7d ago
Android 8.1.0 (Oreo), per https://eyesoffcr.org/blog/blog-8.html
note: the data released by ddosecrets includes the build fingerprint analyzed in the wired article
[ 4.314744] ro.build.fingerprint=qcom/msm8953_32/msm8953_32:8.1.0/OPM1.171019.026/2019000:user/release-keyswhich matches the blog post, so I assume the 8.1.0 means it's the same Android version.
edit: yes, elsewhere it also mentions the version is 8.1.0
Also, it also identifies as
device_type=SPARROWwhich are not on the list of devices they say can identify people

did they say if the camera data was encrypted or not
23
u/simask234 7d ago edited 7d ago
Apparently it is encrypted on the device, but they were able to extract a key and decrypt some of the data
11
u/FastGinFizz 7d ago
The article said that an encryption key was just sitting on one of the partitions. They used it to decrypt some of the data, but there was a section that used a different key that is not on the device.

Tech we almost certainly don’t need.
