GAMES PUBLISHER Konami has asked all users of its website to change their passwords after finding over 35,000 unauthorised logins to the service.
Konami has requested that all users of its Konami ID portal website change their passwords after uncovering a security breach that led to a large number of unauthorised accesses. The firm said that over a period of three weeks 35,252 accounts were accessed through just under four million attempts.
Konami took the commendable decision to release details about the security breach. The firm said that during the period 13 June through 7 July, 3,945,927 login attempts had been made, of which 35,252 were successful. The figures were calculated after the firm detected a large number of login errors on 8 July.
The games publisher said that the customer information that might have been compromised included users' names, addresses, dates of birth, telephone numbers and email addresses. Konami said no changes of customers' information or unauthorised use of paid services have been detected.
Konami said it has strengthened security and "raised its monitoring level". The firm added that user IDs and passwords that were involved in unauthorised logins can no longer be used.
Konami added that the IDs and passwords used for unauthorised logins had been leaked from an external service. The firm did not say what the external service was or whether it still has access to Konami's databases.
Konami joins Ubisoft, Codemasters and Bohemia Interactive in having suffered security breaches that led to the firms asking customers to change their passwords. µ
