Australian Prime Minister Anthony Albanese vowed to tighten breach notification rules to banks after a cyberattack of Optus affected 10 million customers, Reuters reports. Albanese called the breach “a huge wakeup call” as nearly 40% of the country's population had their personally identifiable information stolen. Optus, owned by Singapore Telecoms, claimed the hacker’s IP address “appeared to move between countries in Europe,” but did not state how its system may have been breached. The company said it would provide free credit monitoring for its “most affected customers” for a year.
