I want to know how it works.

What's happening?

You can see him?

Okay, everyone ready?

He's driving up, guys.

So I arranged to meet with a man who was described to me as a big player in the scamming industry.

I'm told he's made a fortune running various investment companies, all of which specialized in financial fraud.

I was also told to be very careful.

Hi.

Hello.

- Thank you so much for meeting us. I am Mariana. - Moshiko.

- Do you have a phone? - I do.

I'd like to have it.

Okay.

- I don't want to be tracked. - So you're gonna turn it off?

Just give it to me. I'll take care of it.

Ok.

I've interviewed hundreds of people through the years.

Moshiko is the first to ever take away my phone.

I asked him to give me the scammer store of Tel Aviv.

We're in the Ramet Gan.

It's an area known as the Diamond District.

Buildings like this and all these skyscrapers you see, they have hundreds and hundreds of people that go to work each day, selling fake investments to people around the world.

- In a lot of these buildings that look completely legitimate, there's actually all this... - Many of the companies there are just fake scams with a name that makes them real.

No one knows what's going on behind closed doors.

Is it an open secret? You seem to know and people in Tel Aviv and Israel? No?

No, they don't want to attract attention.

They don't want reporters calling them.

It's a massive, massive fraud.

They wanna be under the radar.

How many of these companies fraudulent, scamming companies do you think there are ?

Israel?

Yeah.

Five to ten thousand.

No way!

One hundred percent.

Holy...

While the lottery scam in Jamaica is the go-to con, in Israel, it's all about the investment scam.

The depth of this fraud was first uncovered by Simona Weinglass, an investigative journalist who was tipped off by a source working at a scam investment company.

He told me that there wasn't just one company like this, but there were hundreds and they were stealing billions of dollars.

It sounded crazy and it turned out to be true.

Just like in Jamaica, Simona says the investment scams in Israel often start with call centers and leave lists.

Employees of these seemingly legitimate companies cold call potential clients and get them to invest in an exciting trading opportunities.

You start to trade, you'll see your account going up and up.

The retention agent will keep talking to you and getting you to put more and more money in, and then eventually, when a sense that you're not going to put any more money in, they just disappear with the money.
