And, that your site will likely be the victim of an attack of opportunity?
I'll let Tony Perez of Sucuri tell you more about that:
"Meaning that it is not any one individual that is intentionally trying to hack your website, but rather a coincidence.
Something about your site was caught by the trailing net as they randomly crawled the web. It could have been something simple, like having a plugin installed, or maybe displaying the version of a platform."
