QUOTE: We received some reports about spikes on port 10000. The main reason for that is the release of the exploit for Veritas, and used by the Metasploit Framework. ... It seems this exploit is crashing the service listening on port 10000. If sysadmins know they have backup exec installed and they scan the system they will see port 6101 and 10000 normally. After the exploit it will show only the port 6101 still listening."
