This week, we look at war stories from one of the fastest-growing online scams around – email fraud.

Whether it’s invoice redirection fraud or CEO fraud, the phenomenon of faking corporate emails to siphon off thousands from a business is rampant in Ireland.

Adrian Weckler looks through some of the reported incidences of this happening, including to Dublin Zoo, Trinity College and the Louth and Meath Education and Training Board.

He is joined in studio by one of Ireland’s most senior experts on fraud, Conor Flynn of ISAS. Together, they dig down into the mechanics of how the scam takes root, from the first breach to the ultimate withdrawal.

They also look at the role of ‘money mules’, often in the guise of third level students who ‘rent’ their bank accounts to the fraudsters, and what might happen to them.

Finally, the two discuss ways that companies can protect against it.
