A cyber-attack on the computer systems of the bank HSBC in Turkey has compromised customers' card details. Still, officials appear reassuring, saying attackers can't use the data για παράνομες συναλλαγές. Το περιστατικό διαπιστώθηκε την προηγούμενη εβδομάδα μέσω των μηχανισμών εσωτερικού ελέγχου. Η κυβερνοεπίθεση οδήγησε στην αποκάλυψη των δεδομένων των καρτών που αποτελούνται από τον αριθμό, την date expiration date and owner's name. Account numbers linked to the cards have also been compromised.
Οι επιτιθέμενοι έχουν άχρηστες οικονομικές information
The bank, despite the fact that the attackers managed to access this information, states that there is no risk of fraud with the cards, either by making copies or by online transactions. The printing πλαστών καρτών και ανάληψη χρημάτων από ΑΤΜ ή χρήση τους σε καταστήματα λιανικής πώλησης δεν είναι δυνατή απλώς και μόνο επειδή δεν υπάρχουν επαρκή στοιχεία (η μαγνητική ταινία πληροφορίας και ο κωδικός PIN δεν είναι διαθέσιμα) για να υλοποιηθεί αυτό το είδος της απάτης. Στην περίπτωση των online αγορών, οι οποίες απαιτούν λιγότερες πληροφορίες από τους πελάτες, η τράπεζα δεν αναφέρει με σαφήνεια γιατί δόλιες συναλλαγές δεν μπορούν να πραγματοποιηθούν, αλλά ένας από τους λόγους είναι η απουσία του code card security (CVV) from the list of stolen data. CVV (Card Verification Value), or CVC (Card Verification Code) is Verification Code which usually consists of the last three numbers of the code printed on the back of the card. Some banks issue a four-digit CVV that is located on the front of the card. These control codes are required in each online shopping to prove that the buyer really has the card with them and the data has not been stolen from a database.
Micro-markets can be made
On the other hand, some retailers they do not ask for the security code during a purchase. This is the case with micropayments, which are limited to a certain amount. Traders support these transactions in an effort to make the whole buying process easy for their customers. In addition, it has been shown that this way customers are more willing to make small purchases. Through this process, the information that cybercriminals have in their hands is sufficient to carry out a transaction. However, in the event of a malicious transaction, the cardholders are entitled to compensation.
Although the risk of fraud is non-existent in theory, HSBC officials said the bank's customers should not associate any illegal payment as a result of the attack on their systems. At the moment, the bank has no evidence of suspicious activity on the affected accounts, but assured that the attack has no financial risk. To prevent such an incident, the bank has already upgraded security measures. At the same time, an investigation was launched to reveal the identity of the intruders.
