Confirmation of unauthorized access one after another on online securities Okasan Online Securities also confirmed on September 18 at 23:17
Unauthorized access from the outside has been confirmed one after another on the Internet securities.
"Okasan Online Securities" announced that the accounts of the securities accounts of more than 200 customers in total in the three days until the 17th were illegally logged in.
According to the announcement, "Okasan Online Securities" confirmed unauthorized logins from the outside to the securities accounts of 208 customers from the 15th to the 17th of this month.
An unauthorized access was discovered by a contact from a customer who was suspicious that he was in a "password lock" state where he could not enter the password repeatedly by mistake.
It is said that there was no damage such as customer cash leaking to the outside, but the company took measures to prevent it from being done on the web when changing the deposit account linked with the securities account.
On the Internet securities, it has been revealed that SBI SECURITIES also leaked a total of more than 98 million yen from the customer's securities account due to unauthorized access.
For this reason, securities companies are rushing to take measures to prevent damage, and Nomura Securities, the largest company, has switched the procedure for changing the deposit account of the withdrawal destination from the web to mail.
