Metasploit Sending Stages to Random IP's

Hi there,

Just a short question.

When I set-up a regular handler (use/exploit/multi/handler), with LHOST and LPORT, and click exploit without my test computer being online atm. Metasploit starts sending stages to random unknown IP's after a few minutes, so far I've sent stages to the US, Italy, and most recently to several IP's in Saudi Arabia.

This is not supposed to happen, right? Can I get into trouble if metasploit sends a stage to a computer that's being monitored?

The computer I practice on is outside of my LAN, if that matters.

Thanks in advance,

Ulf.
