A person claiming to have hacked the private information of Optus customers says the data has now been deleted from the dark web and apologised for the leak as new personal details of stolen customer information emerged online today.

EFTM and 6PR tech guru Trevor Long broke the news on Breakfast that he had viewed the stolen data online again today and noticed more personal information had been stolen from customers.     

“I’ve actually seen the data and today … I’ve found Medicare numbers in there as well … it’s the worst of the worst in terms of data that could be leak, so we should be careful not to assume the millions of other data is not still out there,” he told 6PR.

Optus customers have been on edge since their data was stolen in an embarrassing breach for the major telco, with the alleged hacker today releasing 10,000 records online and threatening to do it again over the next four days before backtracking later on Tuesday.

University of NSW Institute Cyber Security Enterprise director Nigel Phair says the hacker could be living anywhere and would be hard for authorities to track, despite their online presence.

“Even if they can identify the hacker, they still might not be brought to justice,” he told Breakfast hosts Oly Peterson and Jenna Clarke, in for Gareth Parker this week.
