Today i was reading interesting post by Zone-h.org Which says 1.5 million websites were defaced and reported on Zong-h. Most of the attacks were SQL Injections, LFI, RFI, Web Dav and misconfiguration of the web server or application itself.
The report further says, large number of attacks happened on Linux Operating System. We talk too much about Linux kernel but the first thing is code which need to be written in efficient way.
Some interesting numbers in chart is mentioned on this page too, Up to date stats
