That's ***** luck but do you know if it was socially engineered or an inside job?
Networks definitely need to up their game and put in place a lot more safeguards to prevent sim swap attacks though.
?
My money is on an inside job... we've had fraud on the account twice within 12 months. I know that sounds like an issue at our end. But if we had a leak I'd be down a couple 100k not stopping 1800 at Ikea.
A couple of I phones got tagged onto our account last year o2 cant/wont say whether it was internal or external. And then a sim swap was initiated via the website portal. Our Passwords are long. Not written down. Accessed via lastpass and changed after the first issue.
If I had a keylogger or something then our business bank accounts have a little more in it than paypal.
