"Optus Confirms Hack Exposed Data of Nearly 2.1 Million Australians"

Australian telecom giant Optus recently discovered that nearly 2.1 million of its customers suffered a leak of their personal information during the data breach the company suffered late last month.  The company hired Deloitte to lead a forensic review of the cyberattack.  Optus noted that the affected customers had at least one number from a current and valid form of identification, and personal information, compromised.  In addition, approximately 900,000 customers have had numbers relating to expired IDs compromised, in addition to personal information.  The company also confirmed the exposed information did not contain valid or current document ID numbers for some 7.7 million customers.  The security incident affecting Optus involved a malicious actor gaining unauthorized access to customer information.  Currently, it is unclear how or when the intrusion occurred.  Still, the Australian Federal Police (AFP) warned last week that some phishing and smishing attacks are already targeting Optus customers.  More recently, a BreachForums user claimed responsibility for the attack and said they had deleted the only copy of the stolen data.
