Caller: Supposed NBN Technician

SCAM

Called telling my my NBN was outdated and that other people were accessing my connection.
Told me to run Command Prompt and type in assoc - then verified that the second last line had a unique ID that only NBN could verify and reeled off the numbers of the CLSID - THIS IS NOT UNIQUE.
Then wanted me to install Teamviewer, asked her why she wanted to view/control my computer and after advising her I worked in IT she quickly hung up.
