On May 23, Sumitomo Mitsui Card announced that there was an unauthorized login by a third party in its member app for smartphones, “Sumitomo Mitsui Card Vpass App” (Vpass app). The number of damages is 16,756, and it has been confirmed that the credit card number was not leaked due to unauthorized login, and the credit card misuse damage was not confirmed.
The total number of unauthorized logins is approximately 5 million, and there is no abuse damage
The company regularly conducts 24-hour monitoring using an unauthorized use detection system to check for suspicious card usage. According to the company, this monitoring detected unauthorized logins on August 19th, blocked access identified as unauthorized logins, and implemented emergency responses such as disabling passwords for IDs that were illegally logged in.
In subsequent investigations, there were many IDs and passwords that were specified for unauthorized logins that were not registered with the company, so we used IDs and passwords that third parties may have obtained from other companies' services. It is said that the damage was caused by a “list attack” that attempted unauthorized access.
As of the 22nd, the damage status is 16,756 IDs that may have been illegally logged out of the total number of unauthorized login attempts of approximately 5 million, and the user's name, card name, usage amount, The usage details, available amount, point balance, etc. could be viewed. Since the card usage information can only be viewed with an ID and password, transactions are not possible, and the credit card number is partially hidden, so the company does not identify the credit card number .
As a response to this unauthorized login, the company may have been exposed to unauthorized logins to prevent unauthorized browsing in the future, as some users may have been viewed credit card usage details, etc. Along with disabling the user's password, we are contacting you individually to call for an ID and password change.
