129,000 customers’ data exposed in breach

The personal data of 129,000 customers and 23 businesses was exposed in a 2020 cyber-attack on a telco company. Australia-based Optus revealed in September that 10 million customers had been exposed in a data breach – but it has since come to light that a further two attacks were made on its parent company, Singtel. The hackers had exploited a zero-day vulnerability to obtain sensitive data, which was then published on a public forum.
