Trojan in a push-button phone - how your money is stolen

The topic of hidden and unpleasant surprises in push-button phones has been raised with us many times, but over the years, many moments are erased from memory, which means they need to be refreshed. The presentation "Trojans and backdoors in push-button mobile phones in Russian retail" by ValdikSS also served as an occasion.

Stereotypes claim that the capabilities of push-button phones are noticeably less than those of smartphones, so no surveillance of them is possible in principle. Alas, common sense does not work here as it should, since any mobile phone can collect various information, and push-button devices are no exception. Moreover, those surveillance systems that we see in smartphones originated in the days of push-button phones and have successfully evolved. Another thing is that the button has inherent limitations, for example, it is impossible to determine the exact coordinates of the device, since there is usually no built-in GPS, but you can see the area in which the device works (the accuracy is less, but often this is enough).

Most buyers of push-button phones are not elderly people at all, this part of users is noticeable, but not decisive. Stereotypes play here again, but push-button phones are often needed in rather specific groups, they are popular in them.

Several years ago we talked about the button with Nadia Politsyna, the interview is quite relevant today from the point of view of who is the buyer of such devices.

Push-button phones - millions of buyers annually; which phones are chosen and why; disposable phones; repair cost; nostalgia for the past; Clamshells

Let's figure out what exactly can be found in push-button phones and how to react to it. Let's start with the most common fact, namely the registration of the device on the network, when the manufacturer wants to receive information that the phone has been used. This is done for various purposes, for example, collecting sales statistics, e-guarantee countdown, and so on. Unfortunately, most manufacturers do not warn the buyer in any way that his phone has such functionality and that some data is being transferred outside. This is usually an SMS message and contains the following information:

  • Date
  • IMEI number (here the model is known)
  • Menu language
  • Country
  • Base Station ID

Even worse, the information about the sent SMS message does not appear anywhere in the phone, you can find out about this only in the operator's details. This is a regular SMS, which costs according to your tariff, as a rule, the price varies from 1 to 3 rubles. The problem is that no one warns you about this, and despite the insignificance of the amount, this is your money, which is taken from you without asking.

Usually, such SMS are of a one-time nature, after registering the device in the database, no one is interested in what will happen to it next. The same Transsion (in Russia it is known under the iTel brand), does give out its IMEI database in the public domain, you can see where this or that device is registered.

For manufacturers, such analytics is useful, but in models where there is no Internet connection, the collection is carried out by sending SMS. And the fact that the user does not know anything about it is definitely bad. But such devices do not contain any crime or, moreover, Trojans. It's just a function not documented for the buyer.

In devices that physically have mobile Internet, transmission is carried out using it (even if your tariff does not support mobile Internet, there are tricks on how to transfer information using service packages).

TCL TW30 MoveAudio S600 TWS headphones review

Any decent smartphone manufacturer should offer their own TWS headset with them. So TCL introduced in December on the Russian market not only a flagship smartphone, but also a flagship headset. Let's see what happened ...

Most of the push-button phone manufacturers in Russia take Chinese models, modify them to fit their needs and test the functionality they need. Often, hidden opportunities slip out of sight, or there is not enough competence to ask them to be removed. As a result, the devices receive hidden features that are unknown to the customer. It all turns out at the moment when the devices are already on sale, and users discover incorrect behavior. Correction is possible only in the service center, or in new batches of goods. And this is the problem of choosing devices from companies that do not really monitor their quality. Here the age-old question arises that outwardly phones can be identical and completely identical, but inside they have been completely different work. For some reason, buyers usually judge the sameness of models solely by their appearance.

Now let's move on to models that do not just send SMS, but do it to paid numbers so that the money is debited from your account with the operator. The mobile operator does not see who exactly sends the SMS, the person or the device itself, which creates expanse for scammers. Usually the scheme of fraud is simple to disgrace. The Chinese factory evaluates the partner's skills and, if he sees that he is not very persistent, does not thoroughly check the goods, then he puts Trojans inside to earn extra money. If the partner catches him by the hand, then this functionality is turned off remotely, and the problem is hushed up. But until that moment, profits are being cut from the clients of such a manufacturer.

For example, the presentation mentioned at the beginning talks about the DEXP SD2810 phone, which has a built-in Trojan. The DEXP brand is owned by DNS, which is a huge retail chain with stores all over the country. In pursuit of cheapness, most likely, this model was not tested for hidden features. Although you can think of a hundred reasons why this happened, the fact remains that it happened.

You can find out that the phone sends paid SMS and orders entertainment on its own only from the details, you will not find anything in the list of SMS. Usually in such devices for SMS they put a small amount of 50 rubles or so, they try not to part with sending messages. That is, they create a situation in which a person may not find out for a long time that money is being debited from him. It's important to check your details at least once in a while so you know what's happening on your machine.

It's hard to say that this is a massive problem affecting most feature phones. I asked three Russian operators to analyze SMS from push-button phones and evaluate how many of them have orders for paid services. The result for each of the operators turned out to be quite similar - about 2% of all push-button devices have connected paid services. Considering that some people really buy horoscopes and other content, it is impossible to say that the problem with Trojans is widespread, it is still exotic. In the DEXP line, out of more than a dozen models, there are Trojans in only one device, which is also indicative, they did not keep track of a specific factory. And this does not mean that you need to bypass all devices from DEXP, any conclusions are impossible here, the problem may not even be in a particular model, but only in a part of the batch that entered the market.

Let's say you're facing this problem and your feature phone is wasting money, what should you do in this situation? You need to order the details from the operator, make sure that no one in your family has bought such content. Then you can write a claim to both the seller of this device and the manufacturer. If neither the first nor the second make contact, then you can go to court - compensation for both the cost of the device and moral damage (the latter varies from 10 to 100 thousand rubles, depending on the quality of your lawyer). Most people, of course, do not go to court, but the problem will be settled out of court, it is cheaper and easier for the manufacturer to do so. Moreover, I repeat, such stories are not widespread.

A feature phone does not mean complete protection from surveillance or problems. As you can see, they can be encountered. And here it comes to the fore that you need to buy devices from companies that you know and understand what they are doing. For example, the same Nokia (HMD Global) continues to lead in sales in the Russian market, as the brand is known and trusted by old memory. The cost of Nokia phones is noticeably higher than that of competitors, as well as the quality of software and its checks. This does not mean at all that you need to rush and buy only Nokia, no. But the purchase of a push-button telephone is a little more responsible than it is today, when people do not understand the difference and take what they have, turning a blind eye to the brand of the manufacturer, who he is and what he can do. Yes, this is a simple product, but, as you can see, there can be pitfalls when buying it.

Most people, of course, do not go to court, but the problem will be settled out of court, it is cheaper and easier for the manufacturer to do so. Moreover, I repeat, such stories are not widespread.

A feature phone does not mean complete protection from surveillance or problems. As you can see, they can be encountered. And here it comes to the fore that you need to buy devices from companies that you know and understand what they are doing. For example, the same Nokia (HMD Global) continues to lead in sales in the Russian market, as the brand is known and trusted by old memory. The cost of Nokia phones is noticeably higher than that of competitors, as well as the quality of software and its checks. This does not mean at all that you need to rush and buy only Nokia, no. But the purchase of a push-button telephone is a little more responsible than it is today, when people do not understand the difference and take what they have, turning a blind eye to the brand of the manufacturer, who he is and what he can do. Yes, this is a simple product, but, as you can see, there can be pitfalls when buying it.
