reply to user"s own fault
The Belgacom servers WERE hacked, the breach for my accounts did not come from an unprotected home network or bad wireless LAN security.
My setup has the wireless LAN on a separate network and only one linux firewall machine on the wired network has a md5 hashed password for the account.
I'm 100% sure the failure and breach is at the provider. One of the accounts "breached" was not even in use or active only ...
I can not believe only 2000 accounts are involved !
Don't trust the spoke person at face value ...
