i Have a yii2 project in Ubuntu server, for prevent identifying Web Servers, Operating Systems and yii framework by wappalyzer I do some works, but I did not succeed.
1- expose_php = Off in php.ini.
2- add ServerSignature Off and ServerTokens Prod in apache2/apache2.conf and restart server.
3-add ServerSignature Off in .htaccess
4-change method powered() in /vendor/yiisoft/yii2/baseYii.php and return "--" instead name framework. but in addons wappalyzer or site builtwith I see all information about my site!!
What else should I do?
