As a threatening letter, "I can not guess because the password is 10 digits or more. If you want me to tell you the password,
Pay $ 300 to the account of the following E-Gold (a kind of electronic money).
It is useless to inform the police. They do not know the password.
The only way to restore the file is to pay the money. "
It is written that. The payee's account is randomly selected from approximately 100 accounts.

I guess there are people who really pay .... If it is ten digits or so, if you do your best, it may be somehow.
