Due to Mitel's inability to do anything right our phone system was compromised last week.
Turns out when Mitel setup our system in one of our offices, they left the administrator mailbox password as default. So over one night hundreds of calls were made through our system to all sorts of countries.
Apparently by dialing into our system, after hours you get the auto attendant. Press * to enter your mailbox. By going into the administrator mailbox they were able to change it's extension, to redirect to some system to make calls through.
Not only did they make calls but they deleted all mailboxes. I guess they created a fresh/new install of the voicemail system.
Very irritating.
So...make sure you all change your administrator mailbox passwords!
Any other suggestions to lock down the system?
Thanks
