Filesystem Unlocker

وضاحت

I created this plugin because I am tired of having my WordPress sites being hacked. It is used to completely lock the filesystem with the help of a bash script. The said script is external from the website and ran via cron so you need cron access to make this work. Otherwise, this plugin is useless to you.

This plugin has a known bug. See FAQs.

انسٽاليشن

  1. Upload the plugin files to the /wp-content/plugins/filesystem-unlocker directory, or install the plugin through the WordPress plugins screen directly.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress
  3. Use the left menu Filesystem Unlocker to configure the plugin (this has to be done before configuring and cron’ing scripts)
  4. You need to put the folowing script somewhere on your filesystem, elsewhere then in the webserver’s directory. It needs to be run with the webserver’s privileges or a higher privilege that can chmod files in the webserver’s directory.
  5. Edit the script to match your users, passwords, database prefixes, paths and the like.
  6. Minimaly, cron a job that runs this script every minute of everyday
  7. Ideally, cron this job to run only when you are EFFECTIVELY playing in your ftp. You are sleeping from 10pm to 6am ? Then don’t run the script. It won’t unlock your filesystem if it’s not ran. But then, you need an additionnal script to be ran the minute after you go to sleep to ensure the ftp is locked in the scenario where there was “time left in the parking meter” when your cron stop to execute.

The script in step 4 goes as follows:

#!/bin/bash

FAQ

I use a captcha, database backup or “the like” plugin that needs to write to the filesystem. Will it be locked as well ?

Yes it will. And these plugins will “break”. Such scripts are rarely made for writing elsewhere then the webserver’s directories. As such, you could midofy the lock script to get it to unlock a specific directory after having locked them all. But what would be the point? A hacker could then use this to hack your site anyways.

Can I still use my “the like” plugins with this locking script ?

Yes you could. Either you get them to write elsewhere (then the webserver’s directories) and make sure that they won’t update with their respective author’s updates or you do this another way since you have cron (thus shell) access.

My advice : don’t open a door. Hackers like opened doors. Change the way you do things and you’ll get results you never had…. Security and protection.

Who can unlock the filesystem ?

By default, only people with edit_posts permissions and up can do this. This being because if you can edit a post, well, you could need to upload a picture to put into your post.

Are there any known bugs ?

No known bugs exist at this time. Please notify any and all bugs to the support forums on the plugin’s page.
