There have been many cases in which unauthorized third parties have logged in to internet services using email addresses and passwords leaked from other services. No information registered to LINE, such as phone numbers, email addresses, and passwords, have been compromised.
If you use the same email address and password for LINE as another service, we strongly recommend changing your password.

Reported cases of unauthorized logins
The following types of messages are often sent by the third party when an account is stolen. If you receive messages asking you to do the following from a friend, their account may have been stolen:
• Help me buy prepaid cards
• Help me buy iTunes cards
• I’m in trouble and need you to transfer money to my bank account
As they may change the content of their messages at any time, you should also suspect if your friend’s account has been stolen in the following cases:
• The messages do not sound like the way your friend talks
• A friend whom you have not spoken to for a long time suddenly asks you for money
• The friend's language is unnatural
