#72I have yet to deep-dive into the techical details of Pegasus so this is pure speculation, but if Pegasus demonstrates the feasibility of deploying and executing arbitrary payloads on remote devices without the owner's knowledge or consent wouldn't that raise a blackmail vector with this new program? Again I'm not familiar with the specific exploits used by Pegasus, but is there anything stopping another malicious actor from relying on the same exploits to say install a bootloader that downloads images that would trigger a positive scan?

#73While they are at it they should up the ante and also add COVID misinformation filters, so that a phone refuses to save it and/or doesn't send it anywhere. Would be very topical. There is also racism and other almost universally recognized wrongthink. If you decide to police offline activity as if it's a cloud platform, why not implement all the online platform's automatic content filtering/censorship? /s

EDIT: It appears they are using perceptual hashes, which are likely much more prone to collisions. The following math does NOT apply to the tech Apple is using. >> I mean, who's to say that my hash is actually what they think it is... Let's do the math. assume they are using a UUID for the hash. "For example, the number of random version-4 UUIDs which need to be generated in order to have a 50% probability of at leas…
> "The odds of This number is equivalent to generating 1 billion UUIDs per second for about 85 years." If we're talking about random files, sure. What if the files are intentionally created to match the desired hash? The malicious actor doing this could be a private party intending to disrupt your life, but it could also be law enforcement as a means of gaining access to your device when it would otherwise require a…
Couldn't someone that motivated come up with a dozen other ways to frame someone?
This seems a little alarmist to me.

#75This just means child molesters will seek out PinePhones, Purism Librems, etc. And those phones will acquire reputations as "pedophones", and anyone buying or using one will be immediately considered sus. People with nothing to hide won't mind an OS with surveillance features.
Until few high profile cases of people with nothing to hide getting swatted because of false positive / image crafted by a GAN to create false positive.
That is most likely to happen when the FBI "discovers" child abuse material on the phone of an uncooperative potential informant. In which case they are going to supermax prison where they will be ventilated by the inmates and no one will miss them.

#76I really don't see how this is going to end well, there could be perfectly innocent photos on someone's phone of their own children doing perfectly normal things that kids do. Like a kid running butt naked around the house, or a photo of something like a rash that is sent to a nurse friend for advice on what it is etc. I'm all for protecting children from being abused, but how are they going to filter what is normal…
This system isn't meant for child abuse.
It's going to be used in China against enemies of the state.
Then it will be used domestically for the same.
Apple is a horrific company that you should stop using.

Microsoft implemented this a decade ago.
>The system that scans cloud drives for illegal images was created by Microsoft and Dartmouth College and donated to NCMEC. The organization creates signatures of the worst known images of child pornography, approximately 16,000 files at present. These file signatures are given to service providers who then try to match them to user files in order to prevent further distribution of the images themselves, a Microsoft spokesperson told NBC News. (Microsoft implemented image-matching technology in its own services, such as Bing and SkyDrive.)

There was another round of outrage when the Windows 10 TOS extended this to local storage.
It also has the use case of scanning for DRM violations. (ripped mp3 files or movies)

#78So everyone here just has an FT subscription? I don't see anything but a paywall.

What if an attacker has intentionally produced an image with the same hash as a well known blacklisted image? Then they could send you the new image and fuck up your life.
Hell, what if you were browsing a site like Facebook or Imgur or Reddit, saw an abuse image, reported it, but it still lives in your phone's browser cache?
This is exactly why I use firefox and switch it to in-memory caching only.
Re: Apple plans to scan US iPhones for child abuse imagery
#80> Once a certain number of photos are marked as suspect, Apple will enable all the suspect photos to be decrypted and, if apparently illegal, passed on to the relevant authorities. Haven't Apple previously claimed that their encryption works such that Apple themselves can't decrypt it no matter what? (IIRC this came up during the San Bernadino attack when the FBI requested that Apple decrypt/unlock a suspect's iPhone…
