Australia regulator calls for urgent cybersecurity action to counter Mythos

Australia's corporate watchdog has called on the country's financial industry to take urgent steps to address cybersecurity risks posed by advanced artificial intelligence systems, including a model known as Mythos. The Australian Securities and Investments Commission released a letter to financial services firms on Friday, warning that stronger cybersecurity measures are needed immediately.

"Cyber risk has entered a new era. The arrival of frontier AI models creates opportunity but also materially increases risk, with the ability to expose vulnerabilities faster than many realise," said Simone Constant, ASIC commissioner. She emphasized that the financial sector cannot afford to be complacent as these technologies evolve.

The regulator's letter did not specify details about Mythos, but it highlighted that AI-driven tools can now automate attacks, find weaknesses in systems more quickly, and adapt to defenses in real time. ASIC urged firms to review their security protocols, patch known flaws, and invest in detection systems that can keep pace with emerging threats.

The warning comes as global regulators increasingly focus on the intersection of artificial intelligence and cybersecurity. While AI offers benefits like fraud detection and efficiency, the letter stressed that the same capabilities can be turned against financial institutions. ASIC said it will monitor compliance and may take enforcement action if companies fail to address the risks adequately.
