[asterisk-users] Hacking

[John T. Bittner]

Anyone know how someone can hack an asterisk box and register with every single account on the box.
This box only has 3 accounts, with very complex passwords. Have VoIP blacklist setup and fail2ban...

The hackers were able to make 2 calls to Cuba before my alerting system texted me.

I am running asterisk 16.3 with PJSIP.

This is my only box open to the outside world, a requirement for this one customer.
Looked into my logs... can't find anything out of the ordinary.


Any ideas ?
