Government Scamwatch Site
The scam is a variation on the old one where someone would phone and tell you that you have a virus on your computer and that they need access to rectify the issue. In the latest ones, they pretend that you will be assisting in catching the criminals.
"The scammers claim they are tracking the ‘scammers’ or ‘hackers’, and tell the consumer that their computer has been compromised and is being used to send scam messages. This is where they say with the victim’s help, they can use the victim’s computer and online banking to trap the (fake) ‘scammer’.”
