SIP fraud IP blacklist
Hi,
in case, anyone is interested...
I have started compiling a blacklist of hosts and networks from which
SIP fraud attempts occur.
My criteria currently are:
To block an IP:
- Minimum 3 attacks within one week from the same IP
To block a network:
- Attacks from minimum 3 IPs from that network within 2 weeks
Common criteria:
- Provider does not react to complaints OR
- Provider sends autoreply
