Nigerian e-mail Advance Fee Fraud.
I have over fifty different such e-mail and one day will put them
all together as the concept is the same, but the stories vary from
the sender to the situation.
A person, company, wife, relative, son, daughter sends out an unsolicited
letter by 3e-mail from a Nigerian claiming to be a senior civil
servant or relative of the King or former dictator, etc..
In the letter, the Nigerian will inform the recipient that he is
seeking a reputable foreign company or individual into whose account
he can deposit funds ranging from $10-$60 million that the Nigerian
government overpaid on some procurement contract or money hidden
by the not deceased dictator or whatever.
The gimmick is one you are brought in, seed money needs to be deposited
to make the transfer. One business person I knew put in $40,000
and since it was his own bank, he thought he had protection. Instead
of money being wired in, it was wired out and he was out his $40,000.
