PWS-JU

Detection was added to cover protection against a password stealing trojan originally called "jpg.scr" , having a filesize of 431.681 bytes.

The file is a compressed rar self extracting executable. 

Upon running, a small .jpeg picture of a dog in clothes appears on the screen, using caption/title "error". The temporary file error.jpg  is just an attention drawer.

In the meantime it immediately dropped a few files onto the local system, for example on a Win2000 system: 

• c:\WINNT\Debug\62D4F8F5DDAC.dll , filesize: 156.672 bytes
• c:\WINNT\Debug\62D4F8F5DDAC.exe , filesize: 81.920 bytes
• c:\WINNT\system32\od3mdi.dll , filesize: 259.584 bytes

The above two hexadecimal named files have the file attributes set to Hidden and System.

The main aim of the files is to capture logon and password information, especially for some games, but it may not be limited to just game id's.

Presence of the files:

• "jpg.scr" , having a filesize of 431.681 bytes.
• 62D4F8F5DDAC.dll , filesize: 156.672 bytes
• 62D4F8F5DDAC.exe , filesize: 81.920 bytes
• od3mdi.dll , filesize: 259.584 bytes

Unexepcted display on the screen of a jpeg picture of a dog in clothes appears on the screen, using caption/title "error". The temporary file error.jpg  is just an attention drawer.
