New tricks SMS scam

SMS - scammers come up with more and more new methods to extract money from people. The fact that more and more people have learned about their tricks makes them improve their methods and now the message like “Mom, immediately replenish my account, then call you back” does not lead to the immediate sending of money to a mobile account.
To increase the conversion of new schemes devised "divorce". They come to the aid of new ones how to hack classmates that allow them to send SMS on behalf of others. The fact is that when sending an SMS from such a service, you will receive a message from absolutely any number on your phone, and if this number is recorded in your phone book under the name “Head”, then the “Head” will be the sender in the received SMS. Every day there are more and more such services on the Internet, and the attacker is not responsible for sending SMS with the substitution of the number, that is, it does it with absolute impunity.

So how do these services work:

I decided to sort out this issue and create an analogue of this service and I realized that there is nothing difficult about it.
The fact is that the provider of this service is a kind of cellular operator and as a sender can substitute any number we need. This type of service is official and licensed and is referred to as telematic communication services.
')
In order to use this service, we need to register with the SMS mailing service, then replenish the balance and set up access to your account via the API. Having created a couple of scripts, I got a result that works flawlessly.
But this is if we discuss this problem on a service scale, for personal use, you can use your personal account.
You can determine the authenticity of the SMS sender only by requesting call detail from your operator.
There are also services SIP operators who provide services call with the substitution numbers.

PS All that remains for us so far is to be vigilant and to expect when, after all, the State bodies will consider this problem.
