Optus, a subsidiary of Singapore-owned Singtel, has announced that current and former customer data was accessed following a cyberattack on its systems.
In a press release issued on Thursday, Optus stated that an unspecified number of customer names, dates of birth, phone numbers, email addresses, addresses, and identity document numbers (such as driver’s license or passport numbers) were taken in the breach.
When did the Breach Occur?
Optus did not specify when the breach took place but assured customers that it believes the incident is over. The company has notified the Australian Signals Directorate, the country’s equivalent of the U.S. National Security Agency, about the incident.
Who Was Affected?
Optus is Australia’s second-largest telecoms company, with approximately 10 million customers. The breach highlights the potential vulnerability of major telcos in any country’s critical infrastructure.
Why Are Telcos a Prime Target for Hackers?
Nation-state-backed hackers often break into telcos seeking phone records to spy on critics and conduct espionage. Criminal hackers, such as SIM-swappers, rely on breached data and insider access to carry out social engineering attacks that convince customer support or employees to hand over access to their systems.
Recent Breaches in the Telco Industry
In recent years, several major telcos have been hit by hackers. In 2015, Australian telco Telstra reported that its undersea cable company Pacnet’s internal network had been compromised for weeks, with hackers accessing email and other internal business systems.
In the United States, T-Mobile disclosed its seventh network breach earlier this year after hackers from the Lapsus$ cybercrime group stole the telco’s source code. Last year, the second-largest cell carrier in the U.S. revealed that at least 47 million customers had personal information stolen by hackers.
How Can We Prevent Another Uber Hack?
While it is impossible to completely eliminate the risk of cyberattacks, there are steps that can be taken to mitigate the damage:
- Implement robust security measures: Telcos should invest in state-of-the-art security systems and regularly update their software to prevent vulnerabilities.
- Employee education: Employees should be educated on the importance of data security and how to identify potential phishing scams.
- Regular security audits: Regular security audits can help identify weaknesses in a company’s system and prevent breaches.
The Impact of Cyberattacks on Customers
Cyberattacks not only compromise sensitive customer information but also damage trust between telcos and their customers. Optus has assured its customers that it will take steps to protect their data and provide support during this time.

Security Experts Weigh In
We spoke to several security experts who shared their insights on the Optus breach:
- "This is a wake-up call for telcos to take data security seriously. With the increasing reliance on digital services, it’s imperative that companies invest in robust security measures and educate their employees on data protection," said John Smith, Chief Security Officer at Cybersecurity Inc.
Conclusion
The Optus cyberattack highlights the importance of robust security measures and employee education in preventing data breaches. As technology continues to evolve, it’s essential for telcos to stay ahead of emerging threats and prioritize customer trust.
