According to Australian telecommunications provider Optus, a recent data breach exposed the numbers linked to 2.1 million of its customers’ identification documents.
Without mentioning the precise number of people affected, the wireless carrier announced on September 22 that it had been the victim of a cyber-attack that may have compromised some of its customers’ personally identifiable information. A threat actor published 10,000 Optus customer records on the dark web days after the attack was discovered and stopped, threatening to publish more data unless the wireless provider paid a US$1 million cryptocurrency ransom.
The attackers gained access to user information during the data breach, including names, dates of birth, home and email addresses, phone numbers, and personal identification document numbers.
