Telephone fraud attacks: what are they and how to protect them?

Devastated calls from Mozambique and Congo in the tsunami in Lithuania once again reminded that fraudsters use all possible ways to rely on people, companies and telecommunications operators. There are several dozen such methods, many of which make contact with Lithuanians. So how do you identify cheaters and not target them?

Telephone fraud attacks: what are they and how to protect them?

"The damage caused by telephone scams every year in the world is estimated to be tens of billions of euros, and lighter phone numbers from exotic countries are just one of the ways they are used. They use human credibility and habits: they will call back when they find a missed call, they contact the number in an SMS, they help in the case of a missed friend or friend's visit, they confirm the winning reward by means of an SMS with a special code etc. The gaps in the equipment are sometimes also used. It is important that people can distinguish between mice and cereals, and not resist pressure and temptation, "says Darius Meizeraitis, manager of International Business at Telia.

The attack last weekend reminded people that they did not have to answer all missed calls because we ignored the email sent by the princes. Million heritage lists. And most importantly, be vigilant, because the fraudsters constantly check the credibility of people. What methods of telephone fraud are popular in Lithuania and the world?

He uses human naivety

Most often, Lithuanians face telephone fraudsters who pretend to lose money, online banking, bank cards and personal data to government officials, banks, businessmen and even relatives. Less often, but often – when people try to impose certain goods or services. In both cases, the signs of fraud appear in a hurry. For people, it's important to remember that you can call official offices for state agencies or companies, and if you're talking about a friend or relative, contact them directly.

People should be alert not only in response to calls, but also by sending SMS messages, because in some cases they can cost more than they seem. In Lithuania, there were cases in which one person sent SMS messages with a short tariff number, became a subscriber to services, and every week charges were made for several euros from their account.

"People can be called to send such messages to themselves, for example by offering a lottery and winning a luxury smartphone." There is also a case where such messages were generated automatically by phone when someone clicked on an online ad – "Submit" was required. fake services and lotteries for our clients, but new cases can be repeated at any time, so we always ask our clients to inform our specialists about them "- reminds D. Meizeraitis.

Fraudsters can send SMS messages themselves. Popular foreign fraud occurs when people send SMS messages on behalf of banks, informing them of any changes or obligations of persons, and request further information to call the indicated telephone. After collecting it, the cheater is hit on the other end of the handset, trying to pull out personal bank cards or internet banking data.

Scammers can also send text messages or calls if you've posted an advertisement on the Internet to sell or buy something. The purpose of this scam is to get a person's product without compensation or to give away money without having to send the promised purchase. In such cases, it is easier to protect against fraud by contacting the buyer or seller directly.

You can not protect yourself against all attacks

Calls to SMSes or sending them at high rates can also be triggered automatically by malicious gadgets. These processes take place in the background, and people can not see or stop it. Gadgets that do this are removed from trusted gadget stores, such as the Apple App Store or Google Play, but people should pay attention to the rights the app installs. For example, if the calculator asks you to access your SMS and manage your calls, you should look for another one. In addition, there is a greater risk for those who install gadgets from unreliable sources. However, these types of fraud are monitored globally, and malicious numbers are identified in black lists blocked by international organizations.

People are also dealing with telephone scams while traveling. If your phone connects to an unreliable network operator, this part of its connection may not be directed to where it should be. For example, when you go to a country in Africa to call homeowners, the phone will be lifted, but on the other hand you will hear not Lithuanian "Hello" and exotic local music. You can now connect to the subscriber a second time by dialing the numbers, but the money for the first call is charged and the local operator or agent enters your pocket.

"This is the so-called" false response "attack and people can not protect themselves in any way because they are carried out by operators in these countries, these cases are extremely rare and can only occur in exotic countries. because all our operators agreed on low roaming tariffs on our continent, as well as large, well-known companies operating in many countries, the better the partner has the operator, the less likely it is that his clients will face such problems, "he says. D. Meizeraitis.

Phone fraudsters may try to profit not only from people but also from telecommunications service providers. For example, business customers have telephone stations known as PBX (Private Branch Exchange) that can break mass connections to specific countries, networks or specific numbers to receive revenue from charges for incoming calls between operators. If you notice such cases, inform the operator.

Reserve shame no

"Two things are important to fight off all cheaters, first and foremost it is the operator's experience – the more an enterprise is aware of the different types of crimes, the better the partners, the safer the customers feel. Second, the self-awareness and help of people. activity, and our experts contribute to public education: go to school after school, explaining to their children that it is necessary to set a password on the phone, you can not unlock it, and connection to unknown WiFi can be dangerous "- notes D. Meizeraitis.

To summarize the advice for people, Telia's expert stressed that the key is to be careful and keep the phone in the same position as any other resource: use passwords, do not chatter strangers, do not call unknown numbers and do not lose – block your account and change your password.

Due to the unexpected huge costs of mobile devices, people keep the credit limit. All new Telia customers are granted a credit limit of 100 euros, which can be increased or decreased by calling operators.
