Announcement: Leaks of personal information due to phishing emails.
Dear our valued business partners,
On May 31, 2018, one of our employees of our company received a phishing mail from an attacker who disguised oneself as one of our business partners. The employee entered his own application ID and password at the phishing site. On the same day, it was confirmed that the attacker who disguised oneself as the employee and sent phishing e-mails to some of our employees and some of our business partners and personal and other information of our employees and our business partners was leaked.
(The information, however, on those who are our funds' investors or My Page registered users is not included in the leaked information.)
Immediately after this discovery, we locked the accounts of the attacked employees and changed the password. Later, in order to prevent the damage from spreading, we locked the accounts of all employees, and sequentially unlocked the accounts which we confirmed that there was no damage.
As of June 10, 2018, new leaks are not confirmed.
