Block bad bots and IPs that visit exploit URLs

Your application is hammered by malicious requests that try out exploit URLs. This package detects those and blocks their IP addresses. Blocked users are denied access to your application until their block expires.

Block exploit URLs like /wp-admin and ?invokefunction&function=call_user_func_array&vars[0]=phpinfo.
Block user Agents like Seznam, Flexbot and Mail.ru.
Set the expiration time for IP blocks.
Set IP whitelist/blacklist.

Installation

Step 1: Install the package via composer:

composer require webdevartisan/laravel-shield

Step 2: Make sure to register the Middleware.

To use it on all requests, add it as the first option to the web section under $middlewareGroups in file app/Http/Kernel.php.

protected $middlewareGroups = [
    'web' => [
        \Webdevartisan\LaravelShield\Http\Middleware\BlockMaliciousUsers::class,
    ],
];

To use it on specific requests, add it to any group or to the protected $middleware property in file app/Http/Kernel.php.

protected $middleware = [
        \Webdevartisan\LaravelShield\Http\Middleware\BlockMaliciousUsers::class,
    ];

Step 3: Optionally publish the config file with:

php artisan vendor:publish --provider="Webdevartisan\LaravelShield\LaravelShieldServiceProvider" --tag="config"

Usage

The package uses auto discover. The package uses a middleware class that does the checking and blocking.

Config settings

Enabling shield

You can enable or disable the shield in the published config file, or by setting the value in .env (enabled by default).

SHIELD_PROTECTION_ENABLED=true

Expiration time

Set the block expiration time (in seconds) in the published config file, or by setting this value in .env (3600 seconds by default).

SHIELD_EXPIRATION_TIME=3600

Maximum Attempts

Set the maximum allowed number of malicious requests, before blocking the IP. Default is 5. You can change it in the config or the .env.

SHIELD_MAX_ATTEMPTS=5

Define malicious URLs

Define malicious URLs in the published config file. You need only use part of the malicious string. Matching is case insensitive.

Example: setting wp-admin will block both '/wp-admin', '/index.php/wp-admin/foo' and '/?p=wp-admin'.

Define malicious User Agents

Define malicious User Agents in the published config file.

Example: setting seznam will block User Agent 'Mozilla/5.0 (compatible; SeznamBot/3.2-test4; +http://napoveda.seznam.cz/en/seznambot-intro/)'.

Define storage class implementation

By default, blocked IPs are stored in cache, using storage implementation \Webdevartisan\LaravelShield\Services\BlockedIpStoreRateLimiter::class.

You can create a different storage class you wish to use, and replace it in the config file, or by setting this value in .env:

\Webdevartisan\LaravelShield\Services\BlockedIpStoreRateLimiter

SHIELD_STORAGE_IMPLEMENTATION_CLASS='\Webdevartisan\LaravelShield\Services\BlockedIpStoreRateLimiter'

Testing
