Description:
Names, emails, phone numbers, and more leaked after a recent cyberattack against TPG Telecom.

FULL STORY ======================================================================TPG Telecom confirmed a cyberattack with the country's securities exchange agency Unidentified crooks stole an employee's account login and used it to exfiltrate sensitive data Customers of its iiNet sub-brand were affected

TPG Telecom, a major Australian telecommunications provider, suffered what it described as a limited cyberattack - however, judging by the amount of personal information stolen, that limited comes with quite large quotation marks.

The company issued a statement with the Australian Securities Exchange in which it reported currently investigating a cybersecurity incident when an unauthorized third party accessed its iiNet order management system -
internal software tool used within the iiNet brand to create, manage, and track customer service orders.

The incident was spotted on Saturday, August 16, with the preliminary investigation showing that the origin of the breach were stolen employee account credentials . The company described the attack as limited since the system that was breached does not contain extensive data. However, that data still includes iiNet email addresses for some customers, iiNet landline phone numbers, contact names, contact numbers and residential addresses for a smaller group of customers. Names, addresses, and phone numbers

What the iiNet order management system does not contain are copies or details of identity documents, or credit card and banking information.

The number of affected individuals is in the hundreds of thousands: 280,000 active iiNet email addresses, around 20,000 active iiNet landline phone numbers, around 10,000 iiNet user names, street addresses and phone numbers, and around 1,700 modem set-up passwords, all stolen.

This could trigger a wave of highly convincing phishing emails, voice scams, and malware / ransomware deployments through vulnerable modems. Phishing emails can lead to the compromise of banking accounts, social media accounts, and other services, and could result in identity theft , wire fraud, and
more.

We unreservedly apologise to our iiNet customers impacted by this incident, TPG Telecom said in the announcement.

We will be taking immediate steps to contact impacted iiNet customers, advise of any actions they should take and offer our assistance. We will also
contact all non-impacted iiNet customers to confirm they have not been affected.

There is currently no evidence of abuse in the wild.
