Hi Everyone ,
i write a new online tool for website which can compress/encode your php source code and also make it undetectable by antiviruses if it has something malicious .
tool address : http://fereidani.ir/tools/php_encoder
i should mention i design this program just for research purposes and any illegal use of this tool is at your own risk ,
so so , for test , i used a simple r57shell script ( yeah i am old fashioned :D ) ,
source script size was : 103.5kb
and also virus total scan result was : https://www.virustotal.com/en/file/430989b29bb9ae68aa8a7c674df671183febcc02b9fb01c7fcc606cf5d6f83d3/analysis/1400904835/
detect ratio : 30/52 !!!
Encoder generated file size : 32.5kb
Virus total scan result : https://www.virustotal.com/en/file/d8e870b3754ce2a6bbed69b7a5d82d5f023def9b337b2a0391ce3931b885b0dc/analysis/1400904863/
detect ratio : 0/52 !!!
Final Result :
detection evasion ratio : 100%
compression ratio with default settings : 318% (could reach more ratio by disabling base64 encode)
have a nice day ,
