Modern communication technologies have brought not only convenience, but also new security threats. Thousands of people receive calls or text messages every day, saying that “this number is assigned to the federal security service.” Such messages cause panic and require immediate attention, but they are often shackled by banal fraudulent schemes. It is important to understand how real intelligence agencies operate and how their methods differ from those of telephone scammers.
In this article, we will discuss in detail the number swapping mechanisms used by criminals and explain why. FSB They will never be informed of their actions via SMS. You will learn how to verify the owner of the room in legal ways and what steps to take to protect your personal data and money. The information in this article will help you to keep your cool in a stressful situation.
Statistics show that the number of complaints about calls on behalf of security agencies is growing every month. People lose money believing in the urgency of the situation or become victims of identity theft. It is important to distinguish the official notice from the phishing. Let’s look at how this scheme works and why the word “FSB” should be a question, not a fear, in the context of an incoming call.
Psychology of telephone fraud and methods of intimidation
The basis of the success of fraudsters is psychological pressure. When a person sees a message that his number is supposedly assigned to the special service, the instinct of self-preservation is activated. The attackers are hoping that the victim will not analyze the situation logically. They create artificial urgency by requiring you to call back, press a button, or click on a link right now. In a state of stress, the ability to think critically is drastically reduced.
The authority trick is used. Reference to Federal Security Service It gives weight to the message, making it meaningful and urgent. Fraudsters are often presented as investigators, operatives, or even generals. They use specific jargon, call the numbers of cases or departments to lull vigilance. However, the real work of the special services is based on secrecy, not mass mailings.
⚠️ Attention: Real intelligence officers never report operational developments or surveillance through SMS messages. Any warning that "your number is being tapped" or "fixed to the department" is a lie.
The purpose of such manipulations can be not only direct theft of money, but also the installation of malware on a smartphone. Clicking on a link in a message can activate a script that will access the link. banking and contacts. So the first rule of security is not to follow links from unknown senders, even if they are disguised as government agencies.
Technical aspects: number swapping and spoofing
How is the scheme technically implemented when you receive a message allegedly from security forces? This is done using technology. Spoofing (spoofing) It allows you to change the sender number displayed on the phone screen. The caller can fake a Caller ID so that you will see a number that looks like a police city phone or even a short service number. However, a call back is often impossible or leads to an answering machine.
There is also a method of "call" when the number of the caller is determined as "Unknown" or "Hidden", and immediately after the beep comes SMS. The text of the message may contain a link to a fake site that copies the interface public services Or a bank. The introduction of data on such a resource is equivalent to transferring them to fraudsters. VoIP (IP-telephony) technology allows you to make such calls from anywhere in the world.
It is important to understand that telecom operators cannot guarantee 100% protection against network-level number swapping, as alarm protocols have vulnerabilities. Therefore, the main load of filtering falls on the shoulders of the user and his attentiveness. Modern smartphones have built-in determinants, but they do not always have time to update the database of fraudulent numbers.
How does the number change technology work?
The technology allows you to change the data transmitted in the signal channel when setting a call. The operator sees the real IP address of the caller, but a fake number is broadcast on the screen of your phone. It’s like you send a paper letter, but the address of the sender that belongs to the president is written on the envelope.
To protect against spoofing, it is recommended to install anti-spam applications that have crowdsourcing databases (users themselves mark dangerous numbers). Also, pay attention to the format of the number: if you are called from a long international number or a strange short code, the probability of fraud is close to 100%.
Real powers of the FSB and ways of communication with citizens
The Federal Security Service of the Russian Federation is a serious state body whose activities are strictly regulated by law. Interaction with citizens takes place within the established legal framework. If the service has questions to a specific person, this is not solved through the sending of messages. There are clear procedures, the violation of which makes any evidence inadmissible in court.
Official notification of the call for interrogation or interview shall be made by delivery of the agenda. This is a paper document that is handed personally to the hands under the painting or sent by registered letter through the postal services. The agenda shall indicate the grounds of the call, time, place and name of the official. There are no “urgent SMS” in the legislation.
| Communication method | Used by the FSB | Used by fraudsters |
|---|---|---|
| SMS message | No. | Yes (main method) |
| Paper agenda | Yes (officially) | No. |
| Viber/WhatsApp/Telegram | No. | Often |
| Personal visit | Yes (in custody) | Rarely (threats) |
If we are talking about conducting operational-search measures (ORM), then the citizen is usually not informed about this in advance. The meaning of the ORM is lost if the object is warned. The phrase “your number is being listened to” in SMS is an oxymoron. No one will warn a criminal or suspect that he is being followed.
The only legal way to communicate with the citizen on matters of the case is a paper summons or an official phone call with an invitation to the office for the presentation of documents.
Algorithm of actions when receiving a suspicious message
If you receive a message saying, "This number is assigned to the Federal Security Service," don't panic. Your actions should be consistent and cold-blooded. The first step should always be to stop any active activities with the phone. Do not call back, do not follow links and do not respond to a message.
Check the sender's number. Often, scammers use regular mobile numbers starting with +7 (9...). Official structures use short numbers (e.g. 102, 112) or city telephones with a region code. However, as mentioned earlier, the number can be forged, so a visual check does not give a 100% guarantee.
☑️ What to do with suspicious SMS
Take a screenshot of the message. This will come in handy if the scammers continue to attack or if you need to contact the police to write a statement. After that, the number must be entered in the blacklist of your smartphone. If messages continue to come from different numbers, it makes sense to change your SIM card, although this is an extreme measure.
In case you do contact Caller and he wants money or data, immediately hang up. Record the call time. If the caller introduces himself, write down his "position" and "title". This information will help law enforcement agencies in case of initiation of a case. Remember that your job is to break off contact, not to engage in discussion.
How to check the phone number and owner
There are several legal ways to try to identify the caller, although in the case of professional fraud, they may not work. The first way is to search for a number on the Internet. Enter the number in the search engine line in various formats (with 8, with +7, with spaces and without). Victims often share their experiences on forums, and you will immediately see comments like “These are scammers, they are presented by the FSB.”
The second way is to use messengers. Save the number to your phone’s contacts and check if it has a profile in the phone. Viber, WhatsApp or Telegram. Fraudsters often register accounts for these numbers and put avatars with logos of the special services or photos in the uniform. However, the presence of a profile in the messenger is not proof of the number belonging to state bodies.
Official requests through carriers or databases (such as services like NumBuster or GetContact) show how other people have their numbers recorded. If you see a number marked as “Spam,” “Fraudsters,” or “FSB divorce,” that’s a sure sign of danger. However, relying only on these applications is not worth it, since the base can be filled by the attackers themselves.
Use the function "Number Definer" from your operator (Yandex, MegaFon, MTS, Beeline). They often mark suspicious numbers in red before you even respond.
It is important to note that you can break the real owner of the number through open databases (see below).base-break) an ordinary citizen is prohibited by the law on the protection of personal data. Services that offer such a service for money are often fraudulent or use stolen data. The only legal way is to request through law enforcement agencies in the framework of the criminal case.
Legal Responsibility and Where to Complain
The actions of fraudsters imitating FSB officers fall under several articles of the Criminal Code of the Russian Federation. First of all, this is Article 159 of the Criminal Code of the Russian Federation “Fraud”. If the attackers are represented by law enforcement officers, their actions can be qualified under Article 286 of the Criminal Code of the Russian Federation "Excess of Official Powers" (as part of a group) or Article 327 of the Criminal Code of the Russian Federation "Fake Documents".
Where do I file a complaint? If you receive threats or demands for money, you must contact the police. You can apply through the website of the Ministry of Internal Affairs or in person at the nearest office. It’s also worth notifying your carrier about the number – they can block it at the network level if there are many complaints. To block fake websites, there is a register of Roskomnadzor.
⚠️ Warning: If you are a victim of fraud and lose money, call the bank immediately to block the cards and write a report to the police. Time is critical for refund (chargeback).
The government is actively fighting phone fraud by introducing traffic filtering systems. However, the speed of new numbers and circumvention schemes is high. Civil vigilance remains the main tool of protection. Don’t be afraid to appear as an “inconvenient” subscriber who asks questions and checks information.
Can fraudsters be punished if they call from abroad?
Yes, you can. The police report is registered in any case. Even if the criminals are abroad, their actions in the Russian Federation fall under the jurisdiction of Russian law. The information will be transferred to international search channels, and the number will be blacklisted.
Frequently Asked Questions (FAQ)
Can the FSB really send an SMS?
No, the Federal Security Service does not use SMS messages to notify citizens, call for interrogations or alert them about wiretapping. All notifications are made through paper summonses or an official phone call with an invitation to the building of the department.
What happens if I call back the number from the SMS?
You will most likely be caught on an answering machine or a live operator-fraudster. You will be intimidated, convinced of the reality of threats and lured out money or personal data. Also, the number can be paid, and a minute of conversation from your account will write off a significant amount.
How do I know who called if the number is hidden?
It is impossible to recognize the owner of the hidden number through ordinary applications. This can only be done by telecom operators and law enforcement agencies upon request in the framework of a criminal case. If threatening calls are repeated, report to the police.
I believed the scammers and called the card details. What do I do?
Block the card immediately through the bank application or by phone hotline. Then write a report to the police about theft of funds. Report the fraud to the bank so they can trace the transactions.
Is it true that my number is being tapped?
SMS-message about wiretapping is a standard "scarer" of scammers. Real phone listening is carried out secretly and is never advertised by sending messages to the subscriber. If you are not the subject of a real criminal investigation (which you would most likely know indirectly), then it is simply a bluff.
