My yahoo email account was hacked early this evening! Goodness! A lot of friends called me to say that "I sent an email from London, have been robbed and I needed cash".
I immediately changed my password.
When I opened my mail with the new password, I discovered my inbox and other folders were empty!
I remember last week, I received an email from "Yahoo" asking me to click a link so I do not lose my account.
I just realized now that it was a fake email from Yahoo admin!
My fault, of course, for believing a scammer.
Will try to be more vigilant now.
