It seems like many aren&#x27;t quite getting what&#x27;s going on here...here&#x27;s a brief overview:<p>Shodan.io fancies itself as a search engine where you can search for IOT things (webcams, refrigerators, etc) that are on the internet.<p>They have no technical issues doing this in the IPV4 space, because it&#x27;s easy enough to scan every single address in the space.<p>This isn&#x27;t practical for IPV6.  So, it seems they wanted a way to identify every IOT device in the IPV6 space without having to scan all of it.<p>At least one approach they found was to join the ntp.org pool[1], and effectively donate server time.  Since pool.ntp.org is the default NTP server listed for many linux distros (and thus, probably IOT devices), they now are getting live connections from the exact devices they want to index on their search engine.<p>Once you connect, they scan you back on 100 ports on so (ports unrelated to NTP) to see if you are a webcam, router, or whatever else they want to put in their index.<p>Pretty shady. Kind of like volunteering for a charity so that you can raid their internal mailing list for spam purposes.<p>[1]<a href="http:&#x2F;&#x2F;www.pool.ntp.org&#x2F;join.html" rel="nofollow">http:&#x2F;&#x2F;www.pool.ntp.org&#x2F;join.html</a>
