Anyone know what is this ? I read something about PHP bug.

https://api.myclient.mydomain.net/?_=die('z!a'.'x');&q=die('z!a'.'x');&w=die('z!a'.'x');&e=die('z!a'.'x');&r=die('z!a'.'x');&t=die('z!a'.'x');&y=die('z!a'.'x');&u=die('z!a'.'x');&i=die('z!a'.'x');&o=die('z!a'.'x');&p=die('z!a'.'x');&a=die('z!a'.'x');&s=die('z!a'.'x');&d=die('z!a'.'x');&f=die('z!a'.'x');&g=die('z!a'.'x');&h=die('z!a'.'x');&j=die('z!a'.'x');&k=die('z!a'.'x');&l=die('z!a'.'x');&z=die('z!a'.'x');&x=die('z!a'.'x');&c=die('z!a'.'x');&v=die('z!a'.'x');&b=die('z!a'.'x');&n=die('z!a'.'x');&m=die('z!a'.'x');&eval=die('z!a'.'x');&enter=die('z!a'.'x');

I try to blockj this ip 148.72.202.12 but the blacklist-ip dont work on my system

AH00526: Syntax error on line 20 of /etc/apache2/custom.d/blacklist-ips.conf:
negative Require directive has no effect in <RequireAny> directive
Action 'configtest' failed.
The Apache error log may have more information.

Interesting attack string that, what version of Apache are you running and what version of the blocker? That error you get shows a version conflict.
