In what I think is a great service to anyone who operates a website, the security service Sucuri has started to publish articles containing answers to user submitted questions. In their latest installment, they answer some general questions such as why anyone would want to hack your site, what they gain by attacking a website, and how to check if your site is infected, which is of course an advertisement for their free site scanner.
Speaking of their scanner, I checked WPTavern the other day and was relieved to see that the site came up clean. I’ve read too many horror stories from people who have had to try and save compromised websites to know that it’s nothing short of a giant pain in the rear to make sure everything is clean.
I think another way to check if the site is infected is if it’s listed in any major DNSBLs, for example if I ping your site, then take the IP then check in mulitple DNBLs it comes out clean http://ip-address-lookup-v4.com/ip/174.132.192.61 , the DNSBL stands for DNS-blacklist!
