Aussies beware: Recent data breach opens floodgates for a string of scams
Although we here at the SDC are heartbroken that so many of our fellow Australians have had their personal information and privacy compromised in the recent Optus data breach just last month, we're not surprised that opportunistic cybercriminals have used this news as an opportunity to roll out a wide variety of scams.
There were thousands of complaints sent to the Australian Competition and Consumer Commission (ACCC) in the weeks after the breach.
We've also been hearing reports of fake compensation claims, SIM card replacement requests, verification prompts, and general threats to customers coming in from all over the country.
As if being worried about our personal information floating around on the dark web wasn't enough!
Customers are now having to deal with hundreds of scammers who are taking advantage of people's concerns (as well as their lack of knowledge) about what's going on.
If you or someone you know has been affected by this data breach – either directly or indirectly – please keep reading for more information on how you can protect yourself against these dangerous scams.
Here are some of the various scams to look out for:
Bill payment error scams
There has been an increase in phishing emails posing as payment mistake warnings, asking recipients to verify account ownership by clicking a link so that the recipient's bill can be completed.
These frauds falsely claim to be affiliated with Optus by exploiting the company's name and logo.
One scam reads: 'There has been an issue with your monthly direct debit to pay for our services. We require you to update all information below, and pay all unpaid balances via our portal below.'
The ACCC has confirmed that Optus is not contacting customers to ask them to 'update' their billing information, and they have advised anyone who has received such a message to verify their accounts on their own or to contact the company via a verified channel.
'Use the organisation's secure app if it has one, or log in to its website using your normal login. You can also call the organisation back using a phone number you have sourced independently, such as from the Contact Us page on the organisation's official website.'
Compensation claims scams
Emails falsely state that users who had their information leaked are eligible for a part of the hefty payment that the data breach perpetrators have been required to pay after being ‘convicted and sentenced’.
The ACCC declared this to be a fraud and refuted any claims of financial compensation currently being provided.
'There is no financial restitution being sent to individuals caught in the data breach at this time,' they said.
Email account closure scams
The ACCC has also raised the alarm about what looks like automatically generated emails alerting users to the expiration of their passwords and other account credentials on a specific date.
The phishing emails ask the recipients to click on links so the sender can 'recover' the user's emails and keep the same password.
The ACCC said: 'Optus is not threatening email account closure if you do not update your password or verify your personal information.'
Ransom threat scams
Another newly reported scam is a text message informing the victim that a ransom of $1 million must be paid in cash because Optus has not replied to a previous ransom demand.
Scammers behind these messages pretend to be the cybercriminals behind the initial data breach and demand immediate payment to the bank account provided.
'If you receive demands to pay money with a threat that your information will be released, delete the message. Scammers are pretending to be hackers to make you give them money,' confirmed the ACCC.
Medicare payment details scam
Given that the data breach exposed Medicare information, some recipients would be more likely to fall for a scam asking them to 'update' their Electronic Funds Transfer (EFT) payment.
The email is full of links to other parts of the company's website and promises that clicking them will initiate 'payments for benefits' to the recipient. These messages feature the Medicare and Australian Government logo.
'Scamwatch has received reports about messages impersonating the government,' the ACCC said, adding: 'It is not from the Australian Government – it is a Medicare/MyGov scam.'
'Do not click on links in messages. Instead, go to the official Services Australia website for information.'
Remote access and phone scams
Scammers are taking advantage of the Optus data breach to conduct remote access attacks, in which they convince victims to install malware on their computer or mobile device so that they may gain unauthorised access to it.
Some examples of remote access software mentioned by the ACCC are TeamViewer QuickSupport, AnyDesk, and Zoho Assist.
'Scammers will claim to be from an organisation and provide a reason they need access to your device, including reasons related to the Optus data breach,' it said.
'Scammers may claim they need access to your device to secure it, fix it, investigate what the problem is, or even catch hackers on the device.'
Phone assistance scams
The ACCC has issued a warning about potential phone scammers related to the data breach, including those who claim to be able to help with 'identity rectification'.
'Scammers are offering to resolve compromised information documents if the recipient tells them which sort of document of theirs was impacted,' it said.
Instead of having a suspicious person 'help' you, please adhere to the instructions given here on IDCARE's official help website.
