Payload extract in %systemroot%/saliter.exe
exe file is powered by "Increditools Flash EXE Builder"
SWF File is dropped into %appdata%/IFViewer/[Random numbers]
i'm not a flash cracker pro but i've see nothing related to a serial check inside the flash file.
in attach the swf winlock.

Code: Select all

// Action script...

// [Action in Frame 1]
if (getBytesLoaded() >= getBytesTotal())
{
    gotoAndPlay(5);
} // end if

// [Action in Frame 3]
if (getBytesLoaded() >= getBytesTotal())
{
    gotoAndPlay(5);
} // end if

// [Action in Frame 4]
progress = int(getBytesLoaded() * 100 / getBytesTotal()) add "% - loading Flash...";
gotoAndPlay(3);

// [Action in Frame 19]
stop ();

// [Action in Frame 34]
stop ();

// [Action in Frame 49]
stop ();

// [Action in Frame 64]
stop ();

// [Action in Frame 79]
stop ();

// [Action in Frame 81]
stop ();

// [Action in Frame 96]
stop ();

// [Action in Frame 111]
stop ();

the 'Frame 81' is the bad boy.

I partially (too boring to continue) reversed one of the winlock/ransom variants last year, nothing too interesting that I saw but the concept was a nice one, a lot of money has been paid to unlock these computers. IIRC it dropped the main executing binary from a resource file, used ownerdrawn controls, disabled keyboard input unless it was numbers 0 - 9 for a "pass code" or some shit like this. Definitely Russian origin, the message basically told me that I would have to pay $ to retrieve a pass code and do so with SMS messages or whatever. I think the GUI was blue and black and had white text, no idea which variant that was.

I have also seen other such stuff which simply lock you out by switching desktops to a new one which is created (CreateDesktop/SwitchDesktop) along with some other bells and whistles such as restricting access to taskman (registry key). I have designed such software myself but for administration purposes only
