Re: [PEN-TEST] Decrypting VNC passwords - Tool required

["Batten, Gerald" <GBatten () EXOCOM COM>]

There's a tool called vnccrack.  You can find a copy of it here:
http://www.phenoelit.de/  If you give it the encrypted password, it will
decrypt it for you as well.  I find this usefull when customers ask me if
VNC is safe to use as an administration tool.
