Based on my previous blog entry about emails I have analysed an email that was received from *@ndis.gov.au.

From the email it seems that you have received an email for a Shelby’s plan. A question to ask who is Shelby ?

File name  – Shelby-MyNDISPlan.zip – Have checked online and identified this is indeed a spam email. myonlinesecurity.co.uk/ndisplan-fake-pdf-malware

Extracted file – Shelby- MyNDISPlan.scr – yes the plan is a screensaver 🙂

This is indeed suspicious as the SCR file has an exe embedded which is monlin.exe.

Dynamic analysis files provided no communication to any external hosts or IP addresses.

Likely the file changes values within registry or a process in relation to a screensaver. Also, will try and run the EXE and see the changes.
