Overview -


This is a trojan detection. Unlike viruses, trojans do not
self-replicate. They are spread manually, often under the premise that
they are beneficial or wanted. The most common installation methods
involve system or security exploitation, and unsuspecting users manually
executing unknown programs. Distribution channels include email,
malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer
networks, etc.


Aliases


*       DDoS.Win32.Smurf (AVP)


Characteristics


Characteristics -


This is a Denial of Service attack tool. It's used by an attacker to
send a specified number of ICMP & UDP packets to a victim.

        Hi 

         

        I re-cycled my TCPIP stack and noticed the following message
while it was coming up:

         

        DTCNET400W A denial-of-service attack has been detected; issue
NETSTAT DOS for more information.

         

        The output from the NETSTAT DOS command was:

         

        netstat dos


        VM TCP/IP Netstat Level 530


        


        Maximum Number of Half Open Connections: 258


        


        Denial of service attacks:


                                                           Attacks

        Does anyone know what this means and if it is a real problem? It
looks like the ATTACKS number is rising quickly.

         

        Thank You,
