An urgent warning has been issued to Commonwealth Bank customers after an email scam hit thousands of inboxes.

The scam, which always contains the term ‘CommBank’ was detected last week by anti-virus company Mailguard.

The email asks customers to verify recent transactions on their card, however, when users click the link, they are taken to a address page that redirects to ‘CommBonk’

A Commonwealth Bank spokesman said that they were pooling resources into stopping the scam but some “may still occur”.

“We encourage our customers to stay vigilant and look out for fraud and scams,” the spokesperson told

“We offer our customers the benefit from our 100 per cent guarantee against online fraud where they are not at fault.

“Where there is fraudulent activity, our process is to fully reimburse our customers as quickly as possible to minimise inconvenience.”
