Attacks to telephone frauds: what are they and how to protect themselves?



The devastated calls from Mozambique and the Congo to the tsunami in Lithuania once again reminded that the fraudsters are using all possible means to rely on people, businessmen and telecom operators. There are dozens of these methods, many of which are in contact with Lithuanians. So, how do you identify scammers and not target them?

Attacks to telephone frauds: what are they and how to protect themselves?

“The damage caused by telephone fraud every year in the world is estimated at tens of billions of euros, and lighters from telephone numbers from exotic countries are just one of the ways to use them. They use people's confidence and habits: call back when they find the missed call, contact the number in the SMS, help in case of a missed visit from a close friend or friend, confirm the winning prize by SMS with a special code, etc. P. . It’s important for people to distinguish between mice and grains, not to resist pressure or temptation, ”says Darius Mazeraitis, international business manager at Telia.

The attack last weekend reminded people that they did not need to respond to all missed calls, because we ignored the email sent by the princes. Letters Million worth of heritage. And most importantly, beware, because fraudsters are constantly checking the reliability of people. So, what methods of fraud in the phone are popular in Lithuania and in the world?

Uses human naivety

Most often, Lithuanians face phone fraudsters who pretend to lose money, Internet banking, bank cards and personal data to government officials, banks, business people or even relatives. More rare but common cases are when people try to impose certain goods or services. In both cases, signs of fraud are published in a hurry. It is important for people to remember that you can call official offices for government agencies or companies, and if you are talking about a friend or relative, you should contact him directly.

People need to be on their guard not only to answer calls, but also to send SMS messages, because in some cases they can cost more than it seems. In Lithuania, there have already been cases when one person sent SMS-messages with a reduced tariff number, became a subscriber of services, and every week several euro fees were charged from his account.

“People can be called upon to send such messages to themselves, for example, by offering a lottery and winning a luxury smartphone. There is also a case when such messages are automatically generated by the phone, when someone has clicked on an online advertisement – the “Send” button is required. We block such 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. Meizeratis.

Fraudsters can independently send SMS-messages. Popular overseas fraud is that people send SMS messages on behalf of banks, inform them of any changes or obligations of people and require additional information to call the specified phone. Having collected it, the fraudster hit the other end of the tube, trying to pull out personal bank cards or online banking data.

Fraudsters can also send an SMS message or a call if you have placed an ad on the Internet to sell or buy something. The purpose of this deception is to obtain the product of a person without consideration or to give money without sending the promised purchase. In such cases, it is easier to protect yourself from fraud by simply meeting the buyer or seller immediately.

You cannot protect yourself from all attacks.

Calls or sending SMS at premium rates can also be automatically triggered by malicious devices. These processes occur in the background, and people cannot see or stop them. Gadgets that perform such actions are removed from reliable gadget repositories, such as the Apple App Store or Google Play, but people need to pay attention to what permissions are set by the application. For example, if the calculator requests access to SMS and call management, you should look for another. In addition, there is a risk for those who install gadgets from unreliable sources. However, this type of fraud is monitored worldwide, and harmful numbers are identified in blacklists blocked by international organizations.

People also face phone fraud while traveling. If the phone connects to an unreliable operator’s network, this part of its call may not be routed to where it should be. For example, when you go to a country in Africa to call homeowners, the phone is removed, but at the other end you hear non-Hit Hello and exotic local music. You can already connect to the subscriber a second time, having collected money, but money for the first call is charged, and the local operator or intermediary enters your pocket.

“This is the so-called“ False Answer Supervision ”attack, and people cannot protect themselves in any way because they are performed by operators in these countries. These cases are extremely rare and can occur only in exotic countries. In Europe, this is not entirely relevant, since all of our operators have agreed on low roaming tariffs on our continent, as well as large, well-known companies operating in many countries. In the case of other countries, the better a partner is, the less likely his clients are to face such problems, ”says D. Meizeratis.

Telephone fraudsters may seek to make a profit not only from people, but also from service providers. For example, business customers have telephone exchanges, known as Private Branch Exchange (PBX), which can grow into mass calls to certain countries, networks or specific numbers to receive revenue from incoming call charges between operators. If you notice such incidents, inform the staff.

Reserve shame not

“Two things are important for fighting all scammers. First of all, this is the experience of the operator – the more the company is aware of various types of crimes, the better the partners, the safer the customers. Secondly, people's self-awareness and help. People tell us about suspicious activities, and our experts contribute to public education: they go to school after school, explaining to their children that they need to set a password on the phone, it cannot be unlocked, and connecting to an unknown WiFi may be unsafe " notes D. Maizeraitis.

Justifying tips for people, the Telia expert stressed that the key point is to remain cautious and keep your phone in the same position as any other asset: use passwords, do not lose strangers, do not call unknown numbers, and losers – block your account and change passwords.

Due to the unexpected huge costs of mobile communication, people retain their credit limit. All new Telia customers receive a credit limit of 100 euros, which can be increased or decreased by calling the operators.
