This risk must be manually downloaded and executed.

When the security risk executes, it creates the following files:
C:\Documents and Settings\All Users\Application Data\[RANDOM ALPHANUMERIC CHARACTERS]\screenshot.jpg
C:\Documents and Settings\All Users\Application Data\[RANDOM ALPHANUMERIC CHARACTERS]\[RANDOM ALPHANUMERIC CHARACTERS].exe
%TEMP%\[RANDOM ALPHANUMERIC CHARACTERS].exe

Next, it modifies the following registry entries to lower the security settings on the compromised computer:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"UpdatesDisableNotify" = "1"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv\"Start" = "4"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wscsvc\"Start" = "4"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\Svc\"AntiVirusDisableNotify" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\Svc\"AntiVirusOverride" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\Svc\"FirewallDisableNotify" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\Svc\"FirewallOverride" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\Svc\"UpdatesDisableNotify" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"FirewallOverride" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"AntiVirusOverride" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"AntiVirusDisableNotify" = "1"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"FirewallDisableNotify" = "1"

It then modifies the following registry entry so that it runs every time an executable file is launched:
HKEY_CLASSES_ROOT\.exe\"(Default)" = "[RANDOM ALPHANUMERIC CHARACTERS]"

Note: this locks the system completely and prevents any file from being executed.

It also creates the following registry subkeys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\Svc
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]\shell
HKEY_CLASSES_ROOT\%s
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]\DefaultIcon
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]\shell\open
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]\shell\open\command
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]\shell\runas
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]\shell\runas\command
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]\shell\start
HKEY_CLASSES_ROOT\[RANDOM ALPHANUMERIC CHARACTERS]\shell\start\command
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\luafv

The security risk then asks the user to buy the software in order to unlock the computer.

It also attempts to contact the following location in order to download potentially malicious files:
[http://]95.168.172.92/api/ur[REMOVED]

2. Restoring settings in the registry
Many risks make modifications to the registry, which could impact the functionality or performance of the compromised computer. While many of these modifications can be restored through various Windows components, it may be necessary to edit the registry. See in the Technical Details of this writeup for information about which registry keys were created or modified. Delete registry subkeys and entries created by the risk and return all modified registry entries to their previous values.
