A Teenage Hacker Figured Out How To Get Free Data On His Phone (vice.com)

An anonymous reader quotes a report from Motherboard: Jacob Ajit is 17 and he just hacked his way to getting free phone data, presumably so that he can do whatever it is that teens do online these days without alerting his parents with overage fees. According to a Medium post Ajit posted on Wednesday, he made his discovery while playing around with a prepaid T-Mobile phone with no service. The phone was still able to connect to the network, although it would only take him to a T-Mobile portal asking him to renew the prepaid phone plan. For some reason, though, Ajit wrote that his internet speed test app still worked, albeit through a T-Mobile server. Ajit figured out that he was able to access media sent from any folder labelled "/speedtest," possibly because T-Mobile whitelists media files from speed tests regardless of the host. He tested his theory by setting up a "/speedtest" folder on his own site and filled it with media, including a Taylor Swift music video, which he was able to access. Ajit writes that he then created a proxy server that allows users to access any site with this method. All a T-Mobile user has to do is go to this page and input any URL they want to visit. "Just like that, I now had access to data throughout the T-Mobile network without maintaining any sort of formal payments or contract," Ajit wrote on Medium. "Just my phone's radios talking to the network's radios, free of any artificial shackles."

Arrest warrent is being drawn up now

Note to teenage idiots: Writing online about your criminal exploits is a bad idea.

What his kid did is called theft of communications services.

T-Mobile probably won't press a criminal charges, but they could, and the kid would be convicted.

As much as all this might have sounded good in your head, when you wrote it, I outright guarantee you that a judge, and jury would trivially be persuaded that your attempt to twist the language has absolutely no legal validity.

This is why we have lawyers, to advise on reality of such things, unfortunately you're clearly not one, so you should probably stop pretending you are in case you give someone completely misguided advice and get them into trouble.

You obviously haven't been keeping track of trends in law relating to digital issues, if you had you'd know that there is no get out clause in the law that allows for wishful thinking posted on the internet by a random non-lawyer.

Like it or not, theft of services is a thing, and this kid would be guaranteed to have been found guilty of it regardless of how desperately you may wish to try and mis-read the law in your favour.

I know this because such cases have been brought and won succesfully since at least the time of the widespread use of phreaking in the 80s. If you want to argue this guy wouldn't be caught you'd need to explain why this guy's bypass of the security measures in place is somehow different to anyone elses. I think you'll struggle though, simply because it's really not.

The real reason it works:

Why would T-mblie want you to do speedtest on an inactivated SIM? They don't.

It is a side-effect of them cheating on the speed test. What happens is that speed-test traffic is given #1 priority over everything else.
The first thing the network checks is "is this a speed-test?" If so, it bypasses everything else non-essential, including the accounting system.

So this is not just a way to get free data, but to get faster data, if you have a decent proxy.
But surely a large corporation would never cheat on product performance tests? [cough]VW , Samsung, LG, ...[cough]. Can anyone test this?

How the fuck is that racist?

Because apparently everything is, but only if you're white. Didn't you get the memo?
