FL Rep Randy Fine filed a report with the Florida Department of Law Enforcement that the sheriff was going to plant CSAM on his computer and arrest him for it.

They are even in the same political party.

Indeed this is not new and has probably been happening for many years already. There are services advertising on dark net markets to “ruin someone’s life” which means you pay some Ukrainian guy $300 in Bitcoin and he plants CSAM on a target’s computer.

> Just insert a known CSAM image on target's device.

Or maybe thirty. You have to surpass the threshold.

Also, if Twitter, Google, Microsoft are already deploying CSAM scanning in their services .... why are we not hearing about all the "swatting"?

Their implementations are not on-device and thus it's actually significantly more difficult to reverse engineer. Apples unique implementation of on-device scanning is much easier to reverse engineer and thus exploit.

Now apple is in this crappy situation where they can't claim their software is secure because it's open source and auditable, but they also can't claim it's secure because it's closed source and they fixed the problems in some later version because this entire debacle has likely destroyed all faith in their competence. If apple is in the position of having to boast "Trust us bro, your iPhone won't be exploited to get you SWATTED over CSAM anymore, we patched it" the big question is why is apple voluntarily adding something to their devices where the failure mode is violent imprisonment and severe loss of reputation when they are not completely competent?

This entire debacle reminds me of this video: https://www.youtube.com/watch?v=tVq1wgIN62E

Because it's on their SERVICES, not on their user's DEVICES, for one.

Also, regardless of swatting, that's why we have an issue with Apple.

It only happens on Apple devices right before the content is uploaded to the service.

How is that a meaningful difference for the stated end goals, that can explain the lack of precedent.

I think this is where a disconnect is occurring.

In this specific case yes. That is what is supposed to happen.

But Apple also sets the standard that this is just the beginning, not the end. They say as much on page 3 in bold, differentiated color ink

And there’s nothing to stop them from scanning all images on a device. Or scanning all content for keywords or whatever. iCloud being used as a qualifier is a red herring to what this change is capable of.

Maybe someone shooting guns is now unacceptable, kids have been kicked from schools for posting them on Facebook or having them in their rooms on zoom. What if it’s kids shooting guns? There are so many possibilities of how this could be misused, abused or even just an oopsie, sorry I upended your life to solve a problem that is so very rare.

Add to that their messaging has been muddy at best. And it incited a flame war. A big part of that is iCloud is not a single thing. It’s a service, it can sync snd hold iMessages, it can sync backups, or in my case We have shared iCloud albums that we use to share images with family. Others are free to upload and share. In fact that’s our only use of iCloud other than find my. They say iCloud photos as if that’s just a single thing but it’s easy to extrapolate that to images in iMessages, backups etc.

And the non profit that hosts this database is not publicly accountable. They have public employees on their payroll but really they can put whatever they want in that database. They have no accountability or public disclosure requirements.

So even I, when their main page was like 3 articles was a bit perturbed and put off. I’m not going to ditch my iPhone, mainly because it’s work assigned but I have been keeping a keen eye on what’s happening, how it’s happening and will keep an eye out for their chnages they are promising. I’m also going to guess they won’t nearly be as high profile in the future.

>And there’s nothing to stop them from scanning all images on a device.

All images on your device have been scanned for years by ML models to detect things all sorts of things and make your photo library searchable regardless of whether you use an Android or Apple device. That's how you can go and search "dog", "revolver", "wife", etc and get relevant photos popping up.

I don't think this is accurate. I don't use the Google Photos cloud service, and searching in the Photos app on my Android phone returns zero results for any search term.

My impression was Google had been doing it for ages.

Ex. This article from 2013 where they talk about searching for [my photos of flowers] https://search.googleblog.com/2013/05/finding-your-photos-mo...

I'm an iOS guy, and don't have an Android device to confirm it. I've got a few photos visible on photos.google.com and they're able to detect "beard", at least. Which, to be fair, it's just a few selfies.

iOS does this pretty well. I searched my phone and it was able to recognize and classify a gun as a revolver from a meme I'd saved years ago. That's not this CSAM technology, just something they've been doing for years with ML.

Right, the Google Photos service does this, but it's a cloud service, it's not on-device.

I looked on our iphones. And its possible I am an edge case. With the restrictions I have on Siri, icloud (the only use for iCloud is some shared albums with family, in lieu of facebook, and find my) etc. My phone doesn't categorize photos by person or do those montages others routinely get within the photos app.

And the only reason I know about them is because my wife asked about them and why our iPhones dont do them.

But we don't put stuff on Facebook. Our photos are backed up to our NAS. Phones backup to a macmini only. Siri and search are basically disabled as much as possible (we have to somewhat enable it for carplay) but definitely no voice or anything.

> Because it's on their SERVICES, not on their user's DEVICES, for one.

Effectively the same for Apple. It’s only when uploading the photo. Doing it on device means the server side gets less information.

A server-side action is triggering a local action. The action is still local.

Who cares that Bad Company XYZ already well known for not caring about customer privacy does it? Wouldn't you want to push back against even more increasing surveillance? Apply was beating the drum of privacy while it was convenient, wouldn't you want to hold their feet to the fire now that they seemed to do a U-turn?

Their point is that the attack vector being described isn’t new, as CSAM could already be weaponized against folks, and we never really ever hear if that happening. So the OP is simply saying that perhaps it’s not an issue we need to worry about. I happen to agree with them.

So in your mind, because so far we've seen no evidence that this has been abused, it's nothing to worry about going forward? And that making an existing situation even more widespread is also completely OK?

> So in your mind, because so far we've seen no evidence that this has been abused, it's nothing to worry about going forward?

Yeah, basically. It doesn't seem like people actually use CSAM to screw over innocent folks, so I don't think we need to worry about it. What Apple is doing doesn't really make that any easier, so it's either already a problem, or not a problem.

> And that making an existing situation even more widespread is also completely OK?

I don't know if I'd say any of this is "completely OK", as I don't think I've fully formed my opinion on this whole Apple CSAM debate, but I at least agree with OP that I don't think we need to suddenly worry about people weaponizing CSAM all of a sudden when it's been an option for years now with no real stories of anyone actually being victimized.

And if it is a problem, not doing this doesn't resolve the problem.

If it were to become a problem in the future, it could become a problem regardless of whether or not the scanning is done at the time of upload on device or at the time of upload on server.

It’s that the situation can’t be a “slippery slope” if there’s no evidence of there being one prior

> I presume this could be used against a rival political party to ruin their reputation - insert bunch of CSAM images on their devices.

Okay, and then what? You think people will just look at this cute picture of a dog and be like "welp, the computer says it's a photo of child abuse, so we're taking you to jail anyway"?

You don't have to add a real picture, just add the hash of a benign, (new) cat picture to the db, then put the cat picture on the phone, then release a statement saying the person has popped up on your list. By the time the truth comes out the damage is done.

> "How can you use it for targeted attacks?" > Just insert a known CSAM image on target's device. Done.

Yes, but then the hash collision (topic of this article) is irrelevant.

> Just insert a known CSAM image on target's device. Done.

You don't even need to go that far. You just need to generate 31 false positive images and send them to an innocent user.

But how will you do that without access to the non-blinded hash table? Then you need access to that first.

Also, “sending” them to a user isn’t enough; they need to be stored in the photo library, and iCloud Photo Library needs to be enabled.

How is this different from server side scanning, the policy de jour that Apple was trying to move away from?

> Just insert a known CSAM image on target's device. Done.

What do you mean “just”? That’s not usually very simple. It needs to go into the actual photo library. Also, you need like 30 of them inserted.

> I presume this could be used against a rival political party

Yes, but it’s not much different from now, since most cloud photo providers scan for this cloud-side. So that’s more an argument against scanning all together.

WhatsApp for example automatically stores images you receive in your Photos library, so that removes a step, and those will thus be automatically uploaded to iCloud.

The one failsafe would be Apple's manual reviewers, but we haven't heard much about that process yet.

> It needs to go into the actual photo library.

iMessage photos received are automatically synced so no. Finding 30 photos take zero time at all on Tor. Hell finding a .onion site that doesn't have CP randomly spammed is harder.....

iMessage photos do not automatically add photos to your photo library. Yes they’re synced between devices but afaik Apple isn’t deploying this hashing technology on iMessages between devices. Only for iCloud photos in the photo library.
