Yep, my details were part of the breach unfortunately. I hate Optus now more than ever.
I left them 2 years ago but they keep my details in a database accessible to the internet? Why? Details leaked are name, email, phone, DOB, home address, drivers license number.
About 4 years ago I emailed them complaining that their marketing team were using my date of birth to send me "birthday deals" on my birthday. Something I never opted in for. I found it creepy because the only reason they knew my DOB was from a sign-up security verification process. So back then they were sharing security details from customer signups to their marketing team for use in promotional material. No respect or care for user's data.
I wonder if a class action can be brought against Optus.
