Personal details of up to 10 million Optus customers were stolen.
Interestingly, the hacker assured deletion of the compromised data.
The Australian Securities & Investments Commission (ASIC) sent a warning email to the Aussie financial market intermediaries, including brokers, against the risks of possible “identity theft and fraud” amid the Optus data breach.
A copy of the email seen by Finance Magnates asked the market intermediaries to be “extra vigilant in verifying and managing customers’ personal information.”
Finance Magnates also reached out to multiple brokers to know about their preparedness with the ASIC warning, however, at least one broker confirmed that it did not receive ASIC’s email.
A Massive Data Breach
Optus is the second largest telecom service provider in Australia. The company created a stir in the country earlier this week after revealing that the personal data of up to 10 million customers were compromised, which include home addresses, drivers' licenses and passport numbers.
It was the largest data breach by scale in Australia.
This wasn’t a 'hack'. Optus literally left the door wide open. The perp simply used a connection that wasn’t password protected to download the data.
THAT’S a bigger story than a hack.
Optus are culpable because the data was exposed and unprotected.
The hacker initially asked for $1 million as ransom from the company and threatened to publish 10,000 Optus customers every day until the money is received. However, an anonymous online account claiming to be the hacker dropped the ransom demand recently and has assured the deleting of the compromised data.
“At this stage, it appears that the data breach is limited to retail customers (and potentially small businesses) while enterprise accounts do not appear to be impacted,” ASIC’s email stated.
“Although it has been claimed that the hacked data has now been deleted, there is no doubt a level of skepticism given the nature of the party involved.”
Indeed, Optus also agreed to bear the multimillion-dollar cost of changing the driver’s license number of Australians affected by the data breach.
“ASIC has issued quite a number of media releases about cybersecurity and combined with the RI Advice, they show the level of scrutiny being applied to these issues. AFSL holders should be taking active steps to actively manage their cybersecurity and identity verification processes, staying on top of all developments and adapting accordingly,” Gerber added.
