Brian, thanks for the input, I have researched this exhaustively to be sure I don’t. We ran an extensive search on the system and could not find this IP address anywhere on the system, but yet they could make calls. This is an IP address from russia, they hit the network for around $20k in October then out of the blue they started being blocked, I am really worried they will find another hole in the system, if there is indeed one.

That is a nice offer, but most likely for you, not us. What I have done is build a front to the dial plan that basically duplicates the acl list, it inspects all calls made to the freeswitch and looks at our version of the acl list, discards what it does not like, took a little work but I have not been able to bust it, gives us a little overhead, would like it to be done automatically in the freeswitch, however, this is a good work around. We use the freeswitch as a tandem between pbxnsip hosted servers and the pstn, that is why someone could generate a lot of traffic before we were alerted, now it is secure. Thanks in any case.

Don't know if you already have more countermeasures in place but I would also add firewall (iptables) rules to *only* allow certain IP ranges so you not only rely on the FreeSWITCH ACL. The 91.212.226.0/24 network is a Provider Independent range owned by some shady Russian outfit (missing city+country in the RIPE reg?) and judging from various traceroutes seems to be currently hosted by as5577.net in Luxembourg (root.lu?): http://trace.die.net/search/?q=91.212.226.23 Regards, Patrick
Hi, Take a look to this reference http://arstechnica.com/tech-policy/news/2011/11/how-filipino-phreakers-turne... Hacker, exploiters, phreakers, etc, etc are reals. Try to secure your network, specially if you handle sensible data (ex. customers info, accounts, etc). Add firewalls, Web App Firewalls, vlan, and other security to your network. Is not good idea to have your FS host machine connected directly to internet relaying in basic protection. On 12/2/2011 5:31 PM, Darcy wrote:
