Looking for malware samples which bypass UAC

Can any one guide/help me in findings malware samples which play or circumvent UAC(User Access/Account controls).
I need to analyze what kind of actions they perform..either they create a new user account or what else.
Thanks in advance

This TDSS sample installs

This TDSS sample installs UACd.sys.

Have fun. :)


Along the lines of the TDSS,

Along the lines of the TDSS, do you know if the coders of the TDSS are also the ones working with GAOP*.sys and pjxyv*.sys? It seems to be following the same behaviors but there are some differences. (I.E. the disallowed list present in TDSS*.sys infections but not any of the others)
Could it just be they released their sdk?


Pretty easy to turn off UAC

Pretty easy to turn off UAC with a single silent registry edit. It does have to be OK'd once, but after that every application will run with full admin privileges and without any UAC prompts on the system ever again.


UAC prompts?
