ID3 is a well known PHP shell - PHP shells are scripts used by "bad
guys" to gain access to your web server through an exploitable page in
your website, for example through a vulnerable include statement.

They are usually scanning thousands of web servers in search of the same
vulnerabilities. You may not be using those vulnerable scripts (like
paypalcart.php in this case) but some other webmasters may do :)

Popular websites get requests like this 24/7 - it's just a matter of
time until your server is found and they start scanning it for
vulnerabilities.
It's a good idea to keep an watch on this stuff, so you can make sure
your websites are not vulnerable.
