‘Fullz’ disclosure: the man with the street words to help parents prevent children falling into fraud

With more young people drawn to the world of fraud, from ‘squares’ to ‘clicking’ and ‘mule herder’, Kaf Okpattah knows the language

Kaf Okpattah can speak the language of scammers. “Squares is one word which comes up a lot. That’s bank cards,” he says. “Fullz … that’s a person’s full financial information.”

In his new book, Scam Nation, he goes through more. “Clicking”, which means using stolen details to commit online crime; “addy”, which is used for the shipping address for fraudulently bought gear; and “mule herder”, meaning someone who recruits and manages people accepting stolen funds. Many of these are words he learned at school, he says.
