Facebook's WhatsApp Has an Encrypted Child Porn Problem (techcrunch.com) 156

Videos and pictures of children being subjected to sexual abuse are being openly shared on Facebook's WhatsApp on a vast scale, with the encrypted messaging service failing to curb the problem despite banning thousands of accounts every day. From a report: Without the necessary number of human moderators, the disturbing content is slipping by WhatsApp's automated systems. A report reviewed by TechCrunch from two Israeli NGOs details how third-party apps for discovering WhatsApp groups include "Adult" sections that offer invite links to join rings of users trading images of child exploitation. TechCrunch has reviewed materials showing many of these groups are currently active.

TechCrunch's investigation shows that Facebook could do more to police WhatsApp and remove this kind of content. Even without technical solutions that would require a weakening of encryption, WhatsApp's moderators should have been able to find these groups and put a stop to them. Groups with names like "child porn only no adv" and "child porn xvideos" found on the group discovery app "Group Links For Whats" by Lisa Studio don't even attempt to hide their nature.

Better manual investigation of these group discovery apps and WhatsApp itself should have immediately led these groups to be deleted and their members banned. While Facebook doubled its moderation staff from 10,000 to 20,000 in 2018 to crack down on election interference, bullying, and other policy violations, that staff does not moderate WhatsApp content. With just 300 employees, WhatsApp runs semi-independently, and the company confirms it handles its own moderation efforts. That's proving inadequate for policing at 1.5 billion user community.
It's a similar problem that WhatsApp, used by more than a billion users, is facing in developing markets where its service is being used to spread false information.

    It's not a 'problem'.

      I don't think the law distinguishes between encrypted and un-encrypted child pornography.

      • If it doesn't distinguish that, why is this "encrypted child porn problem" instead of "child porn problem"?

            Ding, ding, ding! A winner!

            Also, child porn is a societal problem and one that's awkward to address for those who want to insist all moral belief structures, particularly those surrounding sexual behaviors and attitudes, are equal. Much better and easier to scapegoat encryption. Widespread adoption of strong crypto scares the pants off of TPTB. It's also another "this is a thing and we're dong something, so reelect us and give us money!" soundbite opportunity to spam the 24hr news cycle.

  • Isn't Whatsapp tied to your mobile phone number? At least in Switzerland, you'll need to have ID to even use prepaid. There is no such thing as an anonymous telephone number in Switzerland.

    Is that different in other countries? Are there ways to use Whatsapp without a phone? Because otherwise I find it highly questionable to share illegal content on there. What stops any agency from infiltrating the group and collect phone numbers?

            That's certainly true.

            At best you can narrow the target to a sector of 90 or 120 degrees.. Maybe you can work out distance. but if the person is far away from the tower, at best you're narrowing it down to a few blocks.. or tens of blocks..

      Actually in Germany you could - till around 1 year ago - get a pre-paid SIM for example from Aldi/"AldiTalk" without showing your ID, and you didn't even needed it for activation - this has changed.

      However in the U.S.A. knowing from media coverage that the FBI has a great deal of possibilities to prosecute, I would think that they get the IMEI/IMSI logs from a cell-tower and then they got a location and perhaps a route somebody drives, than you can IMSI-Catch someone and pin-point the location pretty exact,

    Uh, hang on a cotton-pickin' second. Isn't WhatsApp supposed to have "end to end encryption?" [whatsapp.com] Didn't they like publish a whole paper describing how their end-to-end encryption made it impossible for third parties to know the content that was being sent? Wasn't it supposed to be impossible for anyone, including WhatsApp themselves, to know the content being transmitted on their system?

    Doesn't end-to-end encryption, where "even WhatsApp" can't see the contents of the messages, sorta preclude the use of moderators to moderate content? That is, if WhatsApp can't see the messages, they can't moderate the messages, right?

    So, um, am I wrong in thinking that WhatsApp's claim to being able to moderate messages and claims that messages cannot be read by WhatsApp are sort of incompatible? Unless WhatsApp's supposed "end-to-end encryption" is more of a bullshit marketing ploy rather than a description of the actual algorithms in play here...

      They do but they have groups as well.

      Similar how this very post is encrypted end (my browser) to end (the slashdot server) yet you can read it.
      In fact the headline is equivalent of saying "Slashdot has an encrypted web troll problem" - the encrypted part literally has nothing to do with it.

      • the encrypted part literally has nothing to do with it.

        Yes, but the idea is to make encryption look evil, that it aids and abets criminals and must be banned. The "kiddie porn" angle is to draw eyeballs and provoke outrage. The government has been hammering on this for decades, trying to pry open private communications.

    This problem is only going to grow in the future. You can't control or reliably censor information on a free and open internet. The only way to ensure that nothing "bad" happens on the internet is to completely lock it down and whitelist everything that is posted. This isn't going to happen.

    In a few years blockchain based messaging apps will be launching and they will not be controlled by Facebook or anyone else. You won't be able to ban anyone. This is something we are going to have to accept and deal with. There will be things you don't like on the internet.

      You underestimate the power of the "think of the children" crowd.
      They'll arrange so that you can only get on the internet by signing in and being verified and your ISP will be watching and actively reporting on everything you do.

    • I get the idea that whitelisting is exactly what is going to happen. Google can already identify us. Next, they're going to develop a successor to the internet that will have zero anonymity. You will need to have an ID card to even move a single byte. Google doesn't agree at all that there will be things they don't like on networks. They are already proud to announce they are firmly against freedom of speech and they will work hard to eliminate it from their world.
    • none of this is new. They were doing this crap via IRC when I was a lad. The encryption isn't very useful since you still need to advertise the crap for trading and there's plenty of honey pots out there to catch these sickos.

      This is just more bullshit fear mongering narrative from the "ban encryption" crowd.

They were less pleased with well-meaning admins wading in and shutting those channels down. It made their jobs harder than when people were providing

        That's the problem right there, though. Whenever anyone considers trying to cure pedophilia, the rest of the LGBTQAY crowd comes out and starts getting mad that you're considering "curing deviant behaviors" and blocks it. So thanks to the LGBTQAYs, we can't try and cure people of something that a lot of people agree hurts children.

      Probably the worst course of action is to make real, live children the only source for satisfying that urge. As much as I find the thought utterly distasteful, cp can be simulated or animated.

      People want child porn and the cure is to stop that desire. Pedophilia is a sexual preference.

      No, it is the result of a sexual orientation. Problem is, society already agreed over the past few decades that sexual orientation is something that someone is born with and cannot be changed.

      If it is possible to change someone's sexual orientation I'm pretty certain we would have done so by now.

        • In other words: What I said.

          I dunno, it's a fine distinction to me: pedophilia is an action, sexual orientation is not, therefore pedophilia is a choice that a person can decline while sexual orientation is not.

          If someone's sexual orientation is "children" they can't help that, while someone who fiddles with children can choose not to.

          (NOTE: I don't offer any opinion on whether sexual orientation can be changed or not - I don't care - but the popular thinking is that it cannot be changed.).

    Groups with obvious CP related names? Maybe, but it could also be an organization that wants to outlaw strong encryption so that they can monitor all communication, and which is safe from prosecution under CP laws.

    There are many claims (which of course may be false) that the FBI is the worlds largest distributor of child porn - done of course to attempt to catch (entrap?) peole trading illegal material.

    This may legitimately be a bunch of incredibly stupid child pornographers, in which case I hope they spend a good long time in prison. OTHO, its sure convenient for organizations that want to stop encryption.
       

    • you think Power cares about CP or children's welfare? It only wants to ensure rivals (political/economic) are kept in check so you need a way to snoop their encryption or access to their computers. So create law so that you can legally do that [get a court order of suspected CP and then hack into them - pure objective of gaining political/economic advantage.]
  • Will be interesting to see what happens when computing power is sufficiently powerful to both break encryption and possibly to match abuse photos to their owners. A lot of traffic is already recorded, it just can't be read currently. In 10 years, when authorities have a clear record of CP being transmitted/received, will there be a lot of doors being knocked down?
  • What good is banning the users and groups going to do?
    They will just move elsewhere...
    Given that what they're doing is illegal, why not report the users to the appropriate authorities?

    • WhatsApp is zero rating (which is against net neutrality...) in every carrier here on Brazil: I think is the same on several countries...
      It's a huge incentive to use (without this incentive, I think it will be barely used: there's several better alternatives...) - add it with end-to-end encryption by design and the great spread in crimes using it occurs!
