Apparently they did more. On 8th Feb, I had these two IP addresses checking out my who.is page.
64.246.165.10
216.145.14.142
I was certainly only curious, because it was a unpublished website with deny-all for all robots., so tried a reverse-ip using Who.is; To my surprise, the who.is page for the above two I.P. didn't load, thought it was maybe my connection, but then, when I used Whois.net to end up with the same result, I knew something was going on.
It was only after I googled the I.P address I found some dutch reverse I.P sites that said it was from comcast servers. Though I have nothing worth hiding, and it was just a testing ground for me, this was apparently not nice. I only got to know about the hack yesterday.
Perhaps they bulk collected data, using comcast servers?
