The telco company does not know whether the hackers involved are state-sponsored or acting on their own.

No Corporate Victims

Optus has said that, in a worst-case scenario, up to 9.8 million people may have been affected by a hack of the company’s database. Kelly Bayer Rosmarin, the CEO of the second-largest telecommunications firm in Australia, revealed this to reporters on Friday.

Rosmarin is optimistic that the real figure is smaller as the company works on deciphering the full implications of the cyberattack.

“We have reason to believe that the number is actually smaller than that,” she said. “But we are working through reconstructing exactly what the attackers have received.”

The chief executive expressed her anger and regret that the hackers, based abroad, broke into Optus’ database to access customer information. The compromised data includes names, addresses, dates of birth, and driver’s licenses.

According to some reports, the attack resulted from the breach of a vulnerable API. Rosmarin did not confirm this. However, she was clear that it only affected individual accounts, not those of corporate bodies.

“We will be identifying specifically which customers (were affected) and proactively contacting each customer with clear explanations of which of their information has been exposed and taken,” she said.
