Protection against fraudulent calls, where the caller fakes numbers and pretends to be someone else, is now much stronger in the Czech Republic. Vodafone operators have built a system against so-called spoofingone, T-Mobile and O2 have interconnected security that prevents fraudsters from hiding behind the numbers of other people or institutions, such as banks and the police. Spoofing protection is free for customers of all three operators, whether they are mobile numbers or landlines.
A scammer calls people, masquerading as a bank or other institution, trying to obtain sensitive information from the recipient, such as login details or passwords, and thus get money. This is roughly what a fraudulent technique called spoofing looks like, where the attacker manipulates the identity of a third party and pretends to be someone else.
"Fraudsters hide behind phone numbers far abroad and it is not easy to stop such fake mobile calls without blocking those people who are really on the move and calling from a foreign holiday. I am therefore very happy that we have now managed to find a common effective solution and can protect customers.,” he says Jan Sanek, Director of Corporate Security at Vodafoneone Czech Republic.
Principle of two-way call verification
The Firewall 2.2 protection system operates on the principle of two-way verification of calls between operator networks. Corporate Security Manager at T-Mobile Jakub Ludvik he adds: "The protective firewall can detect whether the calling number is spoofed and, if the call is fraudulent, blocks it. Two years ago, this solution could only be used between numbers in the T-Mobile network, but thanks to cooperation with O2 and now also Vodafoneonem will ensure maxmaximum possible protection of mobile numbers throughout the territory. "
"I see the joining of all three operators in the fight against fraudulent calls as a crucial step towards max"The sophisticated security system now provides protection across all major mobile networks in the Czech Republic, so we can really effectively block fraudulent calls," he says Radek Sichtanc, Director of Security at O2. Testing of the correct functionality and all aspects of this complex technical solution will continue.
Do not forward verification codes or PINs
As the number of cyberattacks continues to grow worldwide, it is important for users to follow a few rules: never send passwords, verification codes, or PINs to any other user or company. A trusted organization will never ask to send your authorization codes via email, phone, or any other means. If the call seems suspicious, hang up and call back the official number on the institution's website.
And will it be an application, or will they block it automatically?
