On Wednesday, Latitude Group Holdings said that it had found more evidence of large-scale information theft affecting former and current customers across Australia and New Zealand, sending its shares to an all-time low.
Latitude was trying to identify the number of customers affected and the type of personal information stolen by the hacker.
The shares of the Melbourne-based company that provides consumer finance services to major Australian retailers Harvey Norman and JB Hi-Fi, fell by as much as 16.2 per cent on trading resumption. Latitude's stock last traded on March 15, a day before it disclosed the cyberattack.
Our focus remains on containing this attack, progressing our forensic review of the actions taken by the attacker and restoring operational capability gradually over the coming days, Latitude said in a statement.
Over the past few months, a number of Australian firms have reported cyberattacks, and experts say this is due to an understaffed cybersecurity industry in the country.
Tony Sycamore, a market analyst at IG Australia, said the market is losing confidence in the company because of the cyberattack, which is already out of their control.
They are racing against time. Last week, Latitude said personal information of around 328,000 customers, including copies of drivers' licences, was stolen. It took its platforms offline on Monday and said the Australian Federal Police and the Australian Cyber Security Centre were looking into the attack.
