Jacob Ajit, a Virginia high school student, is likewise a hacker who located a loophole that gave him get entry to to T-Cellular’s LTE information community with out a plan—absolutely free.
“One Friday night, I used to be sitting around pretending to be first-class having in reality nothing to do,” he wrote in a Medium post. “I had a TMobile prepaid SIM on a spare phone with no energetic service, so I got here up with a laugh mission: should I somehow get entry to the internet without a statistics plan?”
He could, it turns out. Ajit located that T-Cellular permits gadgets related to its LTE community get admission to some web sites and servers without an account. That unfastened get entry to extends to Ookla’s Speedtest app, which pings a nearby server to check the phone’s add and download speeds. Ookla is owned by using Ziff Davis, PCMag’s parent employer.
by using setting up his very own proxy server, Ajit become able to spoof T-Cell into questioning that the information he was accessing came from Speedtest, whilst in reality his hacked connection had free reign of the net.

“Similar to that, I now had access to information at some point of the TMobile community with out maintaining any form of formal payments or settlement,” he wrote. “Just my phone’s radios speaking to the network’s radios, free of any artificial shackles.”
He stated that it in principle, it’d be very clean for T-Mobile to smell out such a proxy that was attempting to impersonate a whitelisted server. All they’d need to do is restriction their get admission to the servers on Speedtest’s public listing. There are loads of servers, however, and there are probable different web sites and apps that T-Cell may want non-subscribers to have get right of entry to, so imposing the sort of whitelist could be a tedious challenge.
T-Cellular has now not answered to PCMag’s request for touch upon whether or not it plans to restoration Ajit’s loophole, but his publically-available proxy server was not operating as of Friday afternoon.
