hi all, just installed Tenable Nessus vulnerability scanner, thought that id check my system, started Nessus server and then the client in my browser and tryed to scan my system, tryed local host ip, then my network ip (external scan), no problems, thought i'd check an external ip address and choose hackthissite.org, while i was scanning the site my internet security went mental as my system was scanned from an external ip (hackthissite.org's ip), can anyone explain what has happened, or know any thing about hackthissite.org or Tenable Nessus vulnerability scanner?
