Phone fraud: what are they and how to protect themselves?

The ruined talks of Mozambique and Congo numbers in the tsunami in Lithuania have reminded that fraud uses all means of trusting people, companies and communications operators. There are dozens of methods, with many of them coming into contact with Lithuanians. So how do you identify fraud and do not target them?

Phone fraud: 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, while lighters from phone numbers from exotic countries are just a way in which they are used. They use the credibility and habits of the people: Call back when they find a missed call, contact one number in SMS, help with missed visits by close friend or friend, confirm winning price by SMS with a special code and the like. Gap in hardware is sometimes used as well. It is important for people to distinguish between mice and cereals, and not resist pressure or temptation, "said Darius Meizeraitis, International Business Manager at Telia.

The attack this weekend reminded people that they did not have to answer all missed calls because we ignored the e-mail sent by princes. Letter of Million Host Heritage. And most importantly, pay attention as fraudsters constantly check the credibility of people. So what kind of phone fraud are popular in Lithuania and in the world?

Uses human naivety

Often, Lithuanians are not exposed to telephones who pretend to lose money, internet banking, bank cards and personal data to authorities, banks, businessmen or even relatives. Rare but common cases – when people try to introduce certain goods or services. In both cases issues signs of fraud in a rush. For people it is important 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 should pay attention not only to answering calls but also by sending text messages, as in some cases they may cost more than they seem. In Lithuania there have already been cases when a person sent sms messages with short customs numbers were subscribed to the services and each week from their account was charged a few euros of fees.

"People may be invited to send such messages to themselves, for example by offering lottery and winning a luxury smartphone. There is also a case where such messages were automatically generated by the phone when someone clicked on an online advertising – the" Submit "button was mandatory . We block such fake services and lotteries for our customers, but new cases can be repeated at any time, so we always ask our customers to inform our specialists about them, reminds D. Meizerait.

The cheats can send SMS themselves. A popular fraud abroad is when people send sms messages on behalf of banks, inform them of any changes or people's obligations and request more information to call the specified phone. After collecting it, the scam turns off at the other end of the handset and attempts to withdraw personal bank or bank banking data.

Fraud can also send a text message or a call if you have posted an ad on the Internet to sell or buy something. The purpose of this deception is to get a person's product without consideration or to give away money without having to send the promised purchase. In such cases, it is easier to protect you from fraud by simply meeting the buyer or seller directly.

You can not protect yourself from any attacks

Calls to or send sms messages at premium prices can also be automatically triggered by malware. These processes take place in the background and people can not see or stop it. Gadgets that perform such actions are removed from trusted gadget stores, such as Apple's App Store or Google Play, but people should pay attention to the permissions that the software installs. For example, if the calculator asks for access to SMS and call handling, look for another. There is also a higher risk for those who install gadgets from unreliable sources. However, this kind of fraud is monitored globally and harmful numbers are identified in black lists blocked by international organizations.

People are also exposed to telephone fraud when traveling. If the phone is connected to an unreliable operator network, this part of the call may not be directed to where it should be. For example, when you go to a country in Africa to call homeowners, the handset is lifted, but at the other end you hear the non-Lithuanian "Hello" and exotic local music. You can already connect to the subscriber for the second time by calling the money, but the money for the first call is charged and the local operator or intermediary enters the pocket.

"This is the so-called" False Answer Supervision "attack, and people can not protect themselves in any way because they are performed by operators in these countries. These cases are extremely rare and can only occur in exotic countries. In Europe this is not entirely relevant because all our operators have agreed on low roaming tariffs on our continent, as well as large, well-known companies operating in many countries. As for other countries, the better the partner the operator has, the less likely his customers will face such problems, "said D. Meizeraitis.

Phone fraud can try to take advantage of not only people but also from communications providers. For example, corporate customers have phone stations called Private Branch Exchange (PBX), which can break into massive calls to specific countries, networks, or specific numbers to receive revenue from incoming call charges between operators. If you notice such cases, inform the operator about them.

Book shame does not

"Two things are important in combating all fraud. First of all, it's the operator's experience – the more a company is aware of different types of crime, the better the partners have, the safer the customers can feel. Secondly, people's self-awareness and help. People report suspicious activity to us, and our experts contribute to general education: they go to school after school and explain to their children that it is necessary to create a password on the phone, it can not be left unlocked and the connection to the unknown WiFi can be uncertain ", notes D. Meizerait.

Summarizing tips for people, Telia's expert emphasized that the key is to be careful and keep your phone in the same position as any other asset: use passwords, do not drop strangers, do not dial unknown numbers and losers – block your account and change passwords.

Due to unexpected large costs for mobile, people keep their credit limit. All new Telia customers receive a 100 euro credit limit that can be increased or reduced by calling operators.
