I'm wondering if DDOS attacks to PBX or telecommunications systems is possibe real.
According to this links:
it is possible.
There are DDOs attacks to web servers, which mostly give them so much concurrent loads or connections that service get unavailable. Many government or non-profit organizations that suffered this kind of attacks, eventually could choose to shutdown their web server and that's it, waiting for these attacks to end.
For a DDOs attacks to PBX, I imagine that it would result in telephones getting busy or ringing all the time unstoppably. This kind of attack could really damage any kind organization.
Is it possible to do that or are we just in the beginnings?
