I have a form on my website where users can write an enquiry which is sent to my email address. For the past 2 days I have received an odd enquiry. The message reads like this:
Values submitted from web site form:
IP Address : 184.108.40.206
Data : '<?php eval(base64_decode('ZWNobyAic3Q0cjciLnBocF91bmFtZS gpLiI3aDMzbmQiOw==')); ?>'
After searching google for any answers, I found out that it may be some kind of hack. My website seems to be working ok, but I am not website savvy enough to know if it has affected certain areas of the website. How should I treat this?
