Optus, a subsidiary of Singtel with over 10.5 million subscribers and Australia's second-largest mobile operator, has disclosed a security breach. Attackers claim to have obtained the data of 11 million customers, and have demanded $1 million in ransom. A small sample of the stolen data was initially published online.
In response, Optus engaged with law enforcement authorities to investigate the incident. Since no ransom was paid, the attackers published a larger dump of stolen data, allowing other cybercriminals to download and abuse it themselves.
The attackers ultimately withdrew their extortion demands after facing increased attention from law enforcement. They've also apologized to over 10,000 people whose personal data was already leaked.
