The high alert comes after the ATO reported increasing instances of myGov-related SMS and email scams.
The scams look like they have come from a myGov or ATO email address, and request that individuals click on a link to verify their details.
If clicked on, the hyperlink connects to a fake website that requests for details and other personal information for “verification purposes”.
The Australian Cyber Security Centre (ACSC) has warned that these emails or text messages mimic official tax time notifications from myGov or the ATO.
“To make them seem more legitimate, cyber criminals use technology that causes these messages to appear in the same conversation thread as genuine messages from the ATO or myGov,” the ACSC said.
“As always, our advice is don’t click any links and don’t provide the information requested.”
