The UK Financial Conduct Authority (FCA) warns that fraudsters use the details of the companies it authorizes to try to convince people that they are working for a genuine, authorized company. All companies and individuals engaged in financial services activities in the United Kingdom must be authorized or registered by the FCA. The clone of Interactive Brokers (UK) Ltd is not authorized or registered by the FCA but targets people in the UK, claiming to be an authorized company. The FCA notifies that the company’s official website is www.interactivebrokers.co.uk and warns that fraudsters may use the name of the genuine firm, the reference number (FRN) the FCA has provided to the authorized company, or other details.
