Hi, i discover a possible file name extension spoofing in yahoo messenger (lastest),obviously this requires 
that the option "Hide extension for known file types" is enabled in Windows, you need to send a file with this name for 
example: Annakournikova and her friends.jpg€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€€.exe or 
Trojan.txt€€€€€€€€€€€€€€€€.exe Info.txt€€€€€€€€€€€€€€.exe The € characters hide the extension.
 Preguntá. Respondé. Descubrí.
