ANZ Bank-owned online broker ETrade, has been the target of a sustained malicious offshore generated cyber attack.
The denial-of-service attack resulted in thousands of emails flooding the broking site, prompting a cessation of services from Christmas Eve to the New Year period.
According to a Fairfax report, offshore Etrade clients were the worst affected with some countries unable to access accounts for almost two weeks. An ETrade spokesperson confirmed that while overseas clients were , more profoundly affected, Australian clients had intermittent access to their accounts.
Neither ANZ nor ETrade have supplied any detail on the nature of the attack or who the culprit was.
Customers only received an explanation of the outage yesterday stating, "immediate action was taken to restrict access from some overseas locations, but given the nature of the incident we were restricted in what we could communicate with you at the time. Importantly, at no stage was the security of the Etrade website breached."
