Singtel's Optus hit by cyberattack

The attack is already being investigated.

Optus was subject to a cyberattack that resulted in the disclosure of customer information, its parent company, Singtel, announced.

Pieces of information possibly exposed following the attack include names, dates of birth, phone numbers, and email addresses. Addresses and ID document numbers such as driver's licence or passport numbers may also have been leaked.

Optus, however, assured that their customers' payment details and account passwords were not compromised.

“Optus services, including mobile and home internet, are not affected, and messages and voice calls have not been compromised. Optus services remain safe to use and operate as per normal,” Signtel added.

According to Singtel, Optus immediately shut down the attack and is already working with the Australian Cyber Security Centre to mitigate risks to customers.

“Optus has also notified the Australian Federal Police, the Office of the Australian Information Commissioner and key regulators,” Singtel added.

Every quarter, SBR lands on the desks of the founders, CFOs, and directors running Asia's most consequential companies. Every day, they open our newsletter and read our website. It's a room that took twenty years to build — and it's the one most of our partners are trying to get into.

The good news is that the door is open. We work with companies on thought leadership articles, sponsored content, industry summits across Southeast Asia, regional awards programmes, podcasts, and media placements in print and digital. The shape of the right partnership depends on what you're trying to do, which is why we'd rather start with a conversation than send a rate card.

If you have something this room should know about, tell us. We'll tell you honestly whether we can help, and how.

No rate cards until we understand the brief. It's a better use of everyone's time.
