The defacer managed to add a “php file” into the website, named “ph.php.”
Once visited, you will be greeted with a message “Defaced by m4n1l4 pr1d3.” After initial load, a page with black background will appear with text that reads, “u are not alone, u are not one, We are here, Filipino Hackers.”
After full load, the page will print some of “your” details including ,IP address, Host and the buggy browsers(look like a list).
The defacement is posted in one of a Facebook group where I am a member of, could just be a show off since no reason is posted.
Google search also suggests, the same sub domain by PNP was defaced by “Shadow Haxor” some months ago.
