What is a vishing?
Vishing is a fraudulent approach using a phone call, by which the attacker tries to obtain confidential data from the client (personal data, access password for Internetbanking, payment card numbers, etc.) This method is often used as tracing is harder.
The attacker will send you an SMS with some short information that there was a suspicious transaction found on your account. Part of this SMS messages is also a phone number, from which the attacker will contact you or you should immediately call this number. Subsequently, the attacker will introduce himself as calling from your bank. To gain your confidence, he will ask about the verification code of the received SMS. The data will later, or even immediately, be used to fraudulently gain access to the funds in your account. The attacker finishes his call with the information that due to the swift action of the bank the suspicious transaction was not executed and your money is safe.
How to protect yourself against vishing?
Weigh up who are you providing any information to about yourself, your payment cards and phone numbers. Never provide passwords, SMS key for payment confirmation, nor any complete data about the payment card.
