This site got defaced and bit suprised with it. I have no idea why those index file could be written in whole directory from the root to sub directories. Restoring this site was tedious task and exhausted. I was looking to suspicious access on my log but didn’t find any unusual activity. I suspect that the attack was done by doing remote access to web folder or they could enter the root of server.
The hosting company website currently down and doesn’t have any information about it. I take a look by searching the twitter and most dotNet-host‘s customer got their site cracked even though no files are gone, they just adding index files to every directory they found. Some of them are struggling to save their domain which a valuable thing in web.
I am now full recovered and moving all my personal website into my another hosting. Unfortunately, I am not taking any screenshot before recovering my website. It was hacked by anonymous. So yeah, anonymous rules.
