Insurer Prosura has experienced a significant cyber breach, resulting in the compromise of personal customer data. Customers received alarming emails from a self-identified "threat actor," who claims to have accessed sensitive information, including names, email addresses, phone numbers, and policy details. While Prosura confirmed that credit card information has not been exposed, the breach has raised substantial concerns among customers about their data security. The company has halted the sale of new policies and disabled its online self-service portal as it investigates the incident. The breach occurred on New Year's Day, according to the attacker, who criticized Prosura for ignoring previous attempts to address the vulnerability. The individual has threatened to leak the sensitive data unless they reach an agreement with the company. Prosura’s founder stated that the company is implementing additional security measures and has reported the incident to authorities. Some customers have also reported receiving fraudulent emails related to older policies, further complicating the situation. One affected customer expressed anxiety over the breach, particularly regarding potential identity theft and fraud. They noted that, despite not having made any claims on their insurance, they felt vulnerable after receiving the threat actor's email. Prosura's communications have been described as generic, leaving customers uncertain about the specifics of the information that was compromised. The incident highlights ongoing vulnerabilities in corporate Australia, as several high-profile cyberattacks have occurred in recent years, exposing the personal data of millions.
