Smurf attack

[jipvm]

Ik kijk net in mijn router settings en zie dit staan:

02/27/2014 21:44:23 **Smurf** 194.44.127.255, 30803->> (mijn ip) (from PPPoE1 Inbound)

Nu heb ik dit ip adres opgezocht: http://www.ip-adress.com/whois/194.44.127.255

Moet ik me nu zorgen gaan maken en hoe kan ik dit voorkomen?
Alvast bedankt

Techopedia explains Smurf Attack

The following steps lead to a smurf attack:

- Huge numbers of ICMP requests are sent to the victim's IP address
- The source destination IP address is spoofed
- The hosts on the victim's network respond to the ICMP requests
- This creates a significant amount of traffic on the victim’s network, resulting in consumption of bandwidth and ultimately causing the victim’s server to crash.

To prevent a smurf attack, individual hosts and routers can be configured to be non-responsive to external ping requests or broadcasts. Routers can also be configured to ensure that packets directed to broadcast addresses are not forwarded.

Wat je dus kan doen, is de ping reply uitzetten in je modem, dan krijg je vaak geen smurfs meer.
