More Details On The 3rd-Party Apps That Led to Snapchat Leaks 101

Yesterday we posted a link to Computerworld's reports that (unnamed) third-party apps were responsible for a massive leak of Snapchat images from the meant-to-be-secure service. An anonymous reader writes with some more details: Ars Technica identifies the culprit as SnapSaved, which was created to allow Snapchat users to access their sent and received images from a browser but which also secretly saved those images on a SnapSaved server hosted by HostGator. Security researcher Adam Caudill warned Snapchat about the vulnerability of their API back in 2012, and although the company has reworked their code multiple times as advised by other security researchers, Caudill concludes that the real culprit is the concept behind Snapchat itself. "Without controlling the endpoint devices themselves, Snapchat can't ensure that its users' photos will truly be deleted. And by offering that deletion as its central selling point, it's lured users into a false sense of privacy."

          Agreed with the "should not" part.

          However "should not" and "not doing" are two different things - especially for exactly kids that age. It's the age of self-discovery, of rebellion, doing things they know they shouldn't do, without yet realising the consequences.

          In my time (I was that age in the late 1980s), taking nude pics of oneself and sending it to school friends was just not an option. That's probably the only reason it didn't happen back then, or any time before the early 2000s - the time web cams became ubiquitous, and instant digital shots could be made from the privacy of one's bedroom, with little to no chance of parents finding out. Nowadays of course web cams have been replaced by mobile phones, making it even easier.

          It is more reasonable to understand that there are always kids that actually do this, trying to stop them is futile. Instead teaching general computer security as part of modern day computer lessons would be the way to go. One major part should be to have all people understand that if you can see a picture, you can save that picture, period. No matter what the app proclaims. It may be hard, you may not be able to pull it off yourself, but it can be done, and as a result those pics and other data may end up where you don't want them to.

          If they are under 15 then there are a wide range of activities they should not be engaging in, but most likely are still going to try. Because that's how life works for kids. Thus we have the role of the Parents, who are supposed to be keeping an eye on things.
          So yes, I do feel a degree of sympathy for the kids because they are young and stupid about such things, and obviously have parents who either cannot, or will not, monitor their actions to prevent such behavior.

        Banks are regulated by the government. Bank deposits are insured by the government. When banks get robbed depositors do not lose money. If you want to refer to "noobish" days when depositors were vulnerable you have to go back long long before 1999.

      See, I can feel some mild sympathy, basically pity, for those that were stupid enough to think that something electronic and stored in a common format over a common communications medium was secure. That doesn't mean that don't assign at least some blame for their circumstances though.

      This has been a problem since well before 1999. Naked pictures were exchanged on BBSes and on Usenet since the inventions of the scanner and the digital camera. The only difference is that it's easier than ever to do that distribution now, and sharing requiring human interaction has been supplemented by software that seeks out and stores such content.

      Until the technology has actually matured there's no safe solution. Even computer professionals don't necessarily understand all aspects of all of the software that could have access to the content on a user's electronic devices; simple users literally have no chance.

        I could see someone designing a screen that can't be accurately captured by at least a digital camera, but anything that the human eye can see, an analog lens and film can also image. Screens that couldn't be imaged electronically would probably be restricted to the most sensitive of data where any concern for espionage would make it desirable to spend the money to make such a screen work, and where someone couldn't infiltrate with a film camera.

        In short, something of a pipe-dream.

      Teens who want to get laid. Like it or not, cell phones and social media has taken over a lot of the real-world interaction we used to have as teens. Mainly because I didn't have a cell phone until my late teens, much less a camera phone and nothing like social media. A lot of the flirting and teasing that used to happen in dark corners at parties is now happening through texting and sexting online. Not to mention the upkeep of an ongoing relationship, if you wanted to get more graphical than you'd say over a fixed phone line in the hallway you had to hook up in person. Today you're more expected to keep it up all the time, even if you're apart which means sending naughties on Snapchat and such. Yes, sometimes it backfires badly but people in love won't believe their love will stab them in the back. And while I'm pulling this statistic out of my ass, I think most personal photos most of the time aren't shared with anyone but the intended recipient and aren't abused. And I think that still holds true even though these 200k pics leaked.

          Good question: [findlaw.com]

          "Though their laws were created to protect minors from exploitation caused by others, states are prosecuting minors under child pornography statutes for sending nude or otherwise lurid self-portraits, even when the minors sent the selfies without coercion. The common quirk in the laws is that there is no exception for taking or distributing sexually explicit pictures of oneself. Thus, a high school student sending a racy seflie to a boyfriend or girlfriend could subject both themselves and the receiver to prosecution for child pornography. If the picture makes its way around other social circles through online or direct sharing, anyone who received or distributed the photo could also find themselves open to charges."

While looking at said picture, the user can take a screenshot, take a picture of their phone with another camera, or use a variety of apps to capture the image.

    Collecting personal information on users is the status quo. All backends, be it google, apple, ms, collect information on users. It is how they make money and 'improve the product'. So instead of being in a position where everyone can agree that private information is private, we live in a world where we have to really work to understand what information is private, and what isn't. We see this with law enforcement and text messages. Most would say they are private, but law enforcement says they are public information. It is a small jump from text messages to photo sent to another person. If information collection were not the norm for everyone, then perhaps we could be upset that private information is being collected. But the web site provides a service, and of course it is going to take it's cut, in the forms of saving photos, for providing that service.

    This is the way the web works. Service in exchange for private information. If it were 2000 it might be surprising. But it is not. And most everyone who is using snapchat has grown up in a world where such is standard mode of operation.
