WindowsRecovery [Symantec]
Name:
Ultra Defragger
Risk Impact:
Medium

Windows

Behavior

UltraDefraggerFraud is a misleading application that gives exaggerated reports of hard disk errors on the computer.

The program performs a fake hard disk scan and falsely reports back several critical errors. It prompts the user to activate the program in order to resolve the errors. Activation involves visiting a predefined Web page and performing a payment transaction.

Behavior
When the program is first executed, it performs a fake scan of the computer looking for errors.





Report fake errors
When the program has finished scanning, it reports a whole host of disk related critical errors that can be fixed by running the defragmentation option.



If the user chooses to perform defragmentation, the program prompts the user to reboot into safe mode and then proceeds to change the desktop background to a fake safe mode background. It also hides all other application windows and displays its own defragmentation progress window.



Mimicking a real defragmentation process, the fake process can run for some considerable time. All the while, the number of warnings and errors mount up inside the window.




As is normal for such programs, the critical errors cannot be fixed using the non-activated copy of the program. The user is then prompted to pay to activate the application by clicking the Yes (activate) button in order to fix the remaining errors.


If the user chooses to activate the program, a browser window will open and connect to the following URL for payment:
https://secure.defragmentetorstore.com/secure/payments/

If the user clicks on the Help & Support option, a browser window will open and connect to the following URL:
https://secure.defragmentersupport.com/secure/help/


Installation
When the program is executed, it creates the following files:
  • %Temp%\[RANDOM NUMBER 1].exe
  • %Temp%\[RANDOM NUMBER 2]
  • %Temp%\[RANDOM NUMBER 2].exe
  • %UserProfile%\Desktop\Ultra Defragger.lnk
  • %ProgramFiles%\Ultra Defragger\Uninstall Ultra Defragger.lnk
  • %ProgramFiles%\Ultra Defragger\Ultra Defragger.lnk


Next, the program creates the following registry entry so that it executes whenever Windows starts:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\"[RANDOM NUMBER 2]" = "%Temp%\[RANDOM NUMBER 2].exe"

It also creates the following registry subkeys:
  • HKEY_USERS\S-1-Unknown\Software
  • HKEY_USERS\S-1-Unknown\SOFTWARE\Microsoft
  • HKEY_CURRENT_USER\Software\"12B79064-EB17-4f82-9DFE-B975BD26D1DC"
