Blackmail spam

[Teho]

Your e-mail and password was probably in one of the many security leaks that have occured with many major companies in recent years. Lists of these are sold and circulated among scammers such as this one.

He's actually doing you a favour. He's confirming to you that your e-mail and password combination isn't secure anymore.

That is a good point actually.

I doubt I'll figure out exactly where it has come from. I've been using that particular password for nearly 16 years now so it could have come from anywhere. Whilst I do still use it, I don't use it for anything of much importance. The email address has been used for about 10 years, so, again, could have been leaked from just about anywhere.
