Date First Reported: November 2013

Primary Name Associated: Hideaki Kubori

Description of Potential Fraud:


Twenty California firms have notified us that they received an email from the purported Hideaki Kubori, representing Yupiteru Industries, to retain them with regards to a commercial debt collection.

This is a classic bad cheque scam that presents as legal matter requiring the assistance of a lawyer. In this scam lawyers will be duped into wiring real funds from their trust accounts after depositing a fake cheque received as payment from the debtor (who is part of the fraud). See our Confirmed Fraud Page for more of an explanation of how these frauds work and to see other names associated with it. Our Fraud Fact Sheet lists the red flags of a bogus legal matter that is really a fraud.

Here is the initial contact email sent by the fraudster to the lawyer and subsequent response:
