    What's the current thinking on doing nmap scans of things you don't own? Illegal, bad form or who cares? I guess Shodan does it...

        @dguido U.S. Court precedents exist that port scans are not illegal.

        @richinseattle @dguido And, for SQLi attempts on a website you don't own? I mean not really want to hack them, just tests.

        @dguido depends on the target. Opsec vs non-opsec, but I don't really use scanners any more for various reasons. I would say light em up!

        @dguido My first thought is bad form, but I do it without hesitation if I’m frustrated that something isn’t working.

        @dguido Get a VPS in eastern Europe and join the club. There are so many packets flying around, I don't think anyone cares.

        @chort0 @dguido pretty much this. not that I'd ever advocate anything more than a port scan... #ahem

        @dguido I'm not sure any of those are mutually exclusive. But who has time to chase portscans?

        @dguido I think it depends on what scripts you're using if any. Just a standard port scan (even of all ports), who cares?
