In the apache log, I saw the following URI

lib/javascript.php/1591083774/lib/javascript-static.js

As I put that in after the website address, I saw a code and I want to know what is that. Code looks like something like this

I can send the code , but I want to know if that is a hack or injection or not.

M.yui.add_module=function(modules){for(var modname in modules){YUI_config.modules[modname]=modules[modname]}
Y.applyConfig(YUI_config)};M.yui.galleryversion='2010.04.21-21-51';M.util=M.util||{};M.str=M.str||{};M.util.image_url=function(imagename,component){if(!component||component==''||component=='moodle'||component=='core'){component='core'}
var url=M.cfg.wwwroot+'/theme/image.php';if(M.cfg.themerev>0&&M.cfg.slasharguments==1){if(!M.cfg.svgicons){url+='/_s'}
url+='/'+M.cfg.theme+'/'+component+'/'+M.cfg.themerev+'/'+imagename}else{url+='?theme='+M.cfg.theme+'&component='+component+'&rev='+M.cfg.themerev+'&image='+imagename;if(!M.cfg.svgicons){url+='&svg=0'}}
return url};M.util.in_array=function(item,array){for(var i=0;i<array.length;i++){if(item==array[i]){return!0}}
