[App_rpt-users] What is the "debian" user in the DIAL distro?

[Pierre Martel]

Hi Jeremy,

Can you tell us what they did to enter in the system? this would be the
first thing to change on any dial system.

Thanks for letting us know that there is a way to compomise a node, that
way we can prepare our nodes for a futur attack
