@dirtyharry123 says:

IKS has been deactivated, because it connects to some unknown external servers and may even reshare your cards to these servers.(The legality and use of this is questionable)
Also there is no possibility to do any configuration or deactivate it by the menu.
I don't understand how people would not be able to use oscam, if they had access to a valid subscription/smartcard.
So keeping this in mind I cannot help you further, then telling you what files have been altered in order to deactivate "IKS".

/usr/bin/mcam
/etc/hosts

Please note that i had my oscam account hacked in the past...
