On September 22, the wireless carrier announced it had fallen victim to a cyberattack that resulted in the potential compromise of the personally identifiable information of some of its customers, without providing specifics on the number of impacted individuals.
Days after the attack was identified and addressed, a threat actor posted 10,000 Optus customer records on the dark web, threatening to make more information public unless the wireless carrier paid a $1 million ransom in cryptocurrency.
