Upon installing a TwistedHumor download, the installer writes the following other files in addition to the game/animation program:

wnad.exe
wnad.dat
wnad-update.exe

The program may also write a wnad.log file.
It then adds a registry key in HKEY_LOCAL_MACHINESoftwareMicrosfotWindowsCurrentVersionRun so that wnad.exe is executed every time the computer is started.

Upon successful install, wnad.exe initiates a connection to www.twistedhumor1.com that appears to be a sort of 'registration' for the program via SSL:
https://www.twistedhumor1.com/addorder.asp?a=0.02&c=1033145308-548335&b=confirm

It creates and transmits a GUID. The wnad.exe software then performs a key exchange with the server and transmits encrypted (SSLv3) information. We are presently unable to decrypt this transmission.

As directed by its controlling servers, the software may enter a 'sleep mode' for at least ten days after its initial installation. During this sleep mode, it will 'lay low' by not displaying ads.

During normal operation, the program will contact Web sites including, but not limited to, the following for the purpose of downloading advertising for display, and for obtaining configuration/display instructions:
www.rankyou.com
www.twistedhumor.com
www.srv2cpt.com

The wnad.exe program is coded to detect Web browsers installed on your system, most likely to coordinate the opening of new popups with Web browser activity. The version we examined looks for iexplore.exe (Internet Explorer), netscape.exe (Netscape Navigator), and AOL.exe (AOL browser/software).
The path to each program is taken from the Registry keys under HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionApp Paths

The program may also attempt to alter the 'Open' command for the browser so that it loads a page of advertising when opened.
