Math Heavy PDF

You'd think this was self-evident, but now Microsoft has finally provided the math to back it up:

Nigerian/419/advance-fee scammers say so up front in order to weed out the non-gullible, and get the only the most gullible recipients to self-select.

Considering that the cost per e-mail reply to the scammer is more than zero, it's helpful to him/her to pre-select for those most likely to pay off by:

a) saying he's from Nigeria
b) using poor grammar
c) including typos, etc.

"Far-fetched tales of West African riches strike most as comical. Our analysis suggests that is an advantage to the attacker, not a disadvantage. Since his attack has a low density of victims the Nigerian scammer has an over-riding need to reduce false positives. By sending an email that repels all but the most gullible the scammer gets the most promising marks to self-select, and tilts the true to false positive ratio in his favor."

Herley notes that, contrary to what some people think, an advance fee scam is not free for the fraudster. "[E]ach respondent to a Nigerian 419 email requires a large amount of interaction, as does the Facebook 'stuck in London scam.'"

The cost of sending an email may be close to zero, but "emptying bank accounts requires recruiting and managing mules".


So, there you are.

Carry on (non-gullibly) wink

Matt;
I trust that this finds you and your fine family doing acceptably well this evening sir.

We used to get one of those "Nigerian" based scams about every other month at work, but the new anti-spam/virus program we've got now seems to have cut them out. I'm sorry that I've no clue as to which ones we use there.

Anyway Matt, it's nice to see you posting again sir.

All the best to you and yours this Fourth of July Matt.

A friend of my mother's lost thousands in the early 1990s to a Nigerian scammer. It was the classic Nigerian scam of a prince who needs the help of Americans to get his money out of the country, or some such. He always needed just a few hundred dollars more to finalize the deal and make her rich. I think she was wiring them money for years. This was back when it was done by telephone, before it became an internet thing. She was always trying to get my mom to join in with her in becoming super wealthy by just putting in a few hundred dollars. She wouldn't listen to anyone who told her it was a scam.

I think that the FBI should answer these emails. They should provide so many answers that it is impossible for the scammers to find the real answers.

They say they're from Nigeria because the Kenyan cornered the market on fraud.

A few years ago a guy from Boise got involved with one of these. He went so far as to actually go to Nigeria to collect his riches. He got lucky. He only lost $5k and actually got home alive. Others haven't been so lucky.

My common sense explanation of this to people has always run thusly:

With all of the people in the world, if a rich Nigerian (prince/warlord/dictator/used car salesman) died, why and how would they know to contact ME?

In the same way that if I died, I would hope my kids wouldn't find some random person in India to distribute the remainder of my checking account to.

People have to be really, really, really stupid to fall for these things.

To you or me they are obvious, but to some widowed 70 year old shut-in living with 10 cats they might not be so obvious. Her only access to the outside world might be the internet and reality gets distorted when you view the world through a computer screen. It's really no different than scams like Oral Roberts "send me 8 million dollars or God's going to call me home", or the likes of Benny Hinn, just a different twist on the same theme. They both play on the desire to either get rich quick or get into heaven, all it takes is to send them some money and they'll make it happen.

My mother is 94, widowed, and she spends quite a bit of time every day on the web. She laughs at these scams and thinks anyone who falls for one is a complete idiot.
