A Facebook account linked to a British banking group has been hacked and a user’s login details have been stolen.
The attack, which affects about 80,000 users in Canada and the United States, is being investigated by the U.K.’s Serious Fraud Office, according to an email message sent to Reuters.
The breach, which took place on May 22, came days after a U.S. Senate committee released a report detailing allegations of fraud by RBC, which had been under scrutiny since March.
The email says that an unknown number of RBC’s users had been given incorrect login details and that the bank had not been alerted to the problem.
The account was linked to the account of a British bank, Royal Bank of Scotland, and the bank has confirmed that an incident took place.
A statement issued by RBS on Friday said the breach is being referred to the SFO for further investigation.
“We take fraud allegations very seriously and are working closely with the SFC to investigate and take appropriate action,” the statement said.
It said the bank is working with law enforcement agencies to investigate.
“The bank is committed to a robust, secure and transparent banking environment and we are committed to making sure this does not happen again,” it added.
