Big brother sees you: cloud computing on a sim card
This article on Beeline and spammers habrahabr.ru/blogs/telecom/77411 , or rather the comments to it reminded me of one interesting thing, which most likely not everyone knows. And the thing itself is very entertaining.
Did you know that a phone sim card is a full miniature computer? Yes Yes. It is a computer with its own operating system, processor, input / output system, RAM, ROM and EEPROM. For a long time, the sim card has ceased to be just a subscriber ID in the operator’s network. Now it also performs a number of other functions, many of which are known, and some are not. And the most interesting of them is that mobile operators can remotely and almost without the user's knowledge install their own software on it. It can be like various additional menus in the phone like all kinds of MTS-info and so on, as well as other programs, the functions of which we can only guess (sim cards coolers, probably, can even not only guess. Are there such?).
Why did I write that mobile operators can install software for SIM cards remotely almost always without the knowledge of the user? Yes, because in some phones (for example, Nokia smartphones) it is possible to specify the settings in the settings when the phone “asks” the owner permission to exchange SIM card data and the operator.
Last time I noticed on my phone, oathsled by a sim card from MTS, some kind of persistent desire to transmit something from the sim. Another annoying and imposed service - “Be aware”. And how much I did not ask MTS to turn off this “innovative” technology to me - the result did not appear. It's a pity. The once qualitatively distinguished operator focused on the business direction has now become unclear than with advertising and spam. It's a pity.
But I deviated somewhat from the thread of the story. And it led me to having such interesting possibilities on remote installation of software on SIM cards, mobile operators, in fact, can monitor the data on the phone and, if necessary, transfer them to themselves. And then we can see a qualitatively new level of SMS advertising! It will be contextual! After analyzing your SMS and other records)
Ps. In fact, do not worry. All the same, all your SMS pass through your own operator. But this does not mean that he does not decide to use the power of your SIM processor for organizing cloud computing!) So it's time to start developing firewall and antivirus for Sim-cards.
