I set up a website with my own custom PHP code. It appears that people from places like Ukraine are trying to hack it. They're trying a bunch of odd accesses, seemingly to detect what PHP files I've got.
They've discovered that I have PHP files called mail.php and sendmail.php, for instance. They've tried a bunch of GET options like:
http://mydomain.com/index.php?do=/user/register/ http://mydomain.com/index.php?app=core&module=global§ion=login http://mydomain.com/index.php?act=Login&CODE=00
I suppose these all pertain to something like LiveJournal?
Here's what's odd, and the subject of my question. They're trying this URL:
What kind of website is vulnerable to a 32-bit hex number?
