of scripts chosen from when using -sC (but it's still just another category and so can be chosen with --script like any other). On top of updating the docs with information about this new category, I've also updated sections to emphasize that the "default" category, -sC and -A are considered intrusive and should not be run against target networks without permission. The new list is very similar to the previous "safe,intrusive" list: Added: finger, ircServerInfo, RealVNC_auth_bypass Removed: HTTPpasswd Here are the 21 scripts in this new category: anonFTP dns-test-open-recursion finger ftpbounce HTTPAuth HTTP_open_proxy ircServerInfo MSSQLm MySQLinfo nbstat RealVNC_auth_bypass robots rpcinfo showHTMLTitle showOwner SMTPcommands SNMPsysdesr SSHv1-support SSLv2-support UPnP-info zoneTrans
