As originally reported by WhistleOut, the details of roughly 3,000 Telstra customers with Opticomm-based broadband services were contained in the file, which, according to the leaker, contained 47,281 rows of data.

“Today I am posting the the Opticomm Orders database for you to download,” said the leaker “abyss0”.

“In 2023/2024 Opticomm was breached by yours truly resulting in the leak of customer appointment information.”


According to the hacker, the data includes contact names, email addresses, mobile numbers, billing account IDs and more. According to ITNews, much of the data in the file is dummy data.

For context, Opticomm is a telecommunications provider owned by Uniti, known for building fibre networks in new housing estates, and is a rival to the NBN.

Opticomm’s services are sold by a number of different internet providers such as Aussie Broadband, Exetel, iiNet, Superloop and, of course, Telstra.

Speaking with the media, a Telstra spokesperson said the company was aware of the breach and was taking action.

“We’re aware the data file released includes a combination of customer names, email addresses and phone numbers of approximately 3,000 Telstra customers on the Opticomm network,” said the spokesperson.

“We are in the process of contacting all impacted customers and offering them support from IDCare, Australia’s national identity and cyber security community support service.

“We are working closely with Opticomm to investigate how the data was accessed and to notify the relevant authorities.”

Opticomm has also released a statement, saying that it is working with Telstra to “investigate the breach and take appropriate actions”.

A number of other Opticomm providers, such as Aussie Broadband, Superloop and Exetel, have confirmed that their customers were not affected by the breach.
