«… to find the right candidates»
Why would anyone (or anything – as in a software or a web-bot) search for a string like «site:.eu «use our awesome search tool to find the right candidates»» on Google?
Well, probably to extract some information. Personal Identifiable Information / Sensitive Personal Information? Maybe.
For what use? One we can think of: phishing. Interesting, don’t you think?
A quick explanation:
«site:.eu» – searches for sites that have European (.eu) TLD (top level domains)
«»use our awesome search tool to find the right candidates»» – pay attention to the quotes – searches for sites that have this exact string in their pages.
So «somebody» is looking for European websites that provide candidates.
Of course, it might also be a signature of an exploitable script. Or just a WordPress Premium Theme (with a security hole?) – as in the one located here: http://alexgurghis.com/themes/wpjobus/resumes/. Keep your eyes open – you can never be too careful about the plugins/themes you use on your website(s).
