The index.php file is infected with code 64. In WordPress I see an unknown plugin: pluginsamonsters that is installed. Wordfence warns me that jsquery.php has been changed. I reinstalled my database and a new wordpress but the malware comes back. How to get rid of it? * Best regards * —– * Bonjour, Désolé pour ce message en anglais traduit du français depuis Google Traduction… J’ai depuis quelques temps un malware qui redirige un de mes blogs wordpress.

The plugin > gives the attacker full control of the target website and the site is now compromised. > The plugin is visible on the WordPress.com dashboard but is invisible on the > target WordPress site’s plugin list when active. (It is visible when deactivated) > For this attack to occur, the following conditions need to be met: > The site owner must have Jetpack installed. > Jetpack must be configured to > allow the site to be managed from a WordPress.com account. The WordPress.com > account must have compromised credentials. This usually happens when you have > reused an email/password combination on another site or service that has been > compromised. he WordPress.com account must not have two factor authentication > enabled. * Source: [https://www.facebook.com/CVTF.StudiosDOTnet/posts/10160479953070165](https://www.facebook.com/CVTF.StudiosDOTnet/posts/10160479953070165) * This matches with my case as I had JetpPack installed and a somewhat lower-than- ideal security password for my wordpress.com account (I must have set it up prior to using a password manager) * For those who have been affected, I recommend setting up two-factor authentification on WordPress.com or decouple the wordpress.com account from your site altogether. * To clean up you will need server log to check which file was affected (some random files, index.php which contains an encoded redirect script, and especially the/ pluginsamonster/ directory which contains a direct server upload script anyone can use). I’m just going for a fresh reinstall with all the latest security buffs. * Have a good one, * jedd - This reply was modified 8 years ago by [drjedd](https://wordpress.org/support/users/drjedd/).
