Australian telco Optus has disclosed that they suffered a cyber attack which resulted in the personal info of customers including names, DOBs, addresses and contact details being stolen. The attack occurred after hackers broke through the company’s firewall, accessing sensitive information of Optus’ 9.7 million subscribers. The company has confirmed the breach and exposed information but has stated that payment details and account passwords have not been compromised, and that services including mobile phones and home internet were not affected. The thing is, what was stolen is enough to start identity theft campaigns. Which makes this a non trivial event.
