backdoor

A standard configuration of a web server is to execute PHP directives only in files with a .php file extension.

You could configure your web server to execute PHP in files with a .jpg file extension (the specifics depend on which web server you are using) but this would be highly unusual — doubly so because a JPEG image is a binary file and not a text file to start with.

Also note that allowing arbitrary PHP to be accepted as user input and then executed on your server is highly dangerous.

I'm aware I won't get executed when viewing the file but shouldn't the PHP I sent in the body get interpreted?

No. Reading a file into a variable only reads a file into a variable. file_get_contents does not execute PHP directives in user input.

That would also be highly dangerous and PHP isn't that bad.

This is completely normal and expected.

for..in iterates over all enumerable own properties on the object in question. Then it does the same for that object's internal prototype, and so on - until it reaches the beginning of the prototype chain (which is often Object.prototype).

If you put an enumerable property onto Object.prototype, then any object (that inherits from Object.prototype) you iterate over with for..in will eventually iterate over that property you added.

can't this be exploited as code injection along with this?

I suppose - malicious code can modify Object.prototype and do a whole lot of other nasty things, so take care not to run anything that isn't trustworthy.

Accidental prototype pollution (even occasionally from user input) isn't an uncommon problem that libraries sometimes run into. A good rule of thumb is to use static key names everywhere - if you need something dynamic, use a Map instead of an object.

Based on the output of the console.log, your message variable is actually a CommandInteraction, which does not have a createReactionCollector method.

Taking a closer look at your code, it appears you want to listen to reactions to a new message that you sent, which contains the checkmark. Thus, your code should look like this:

The query builder is macroable so in your service provider you can probably do:

In an attempt to clarify the steps I mentioned in the comments, I'll write it all out here.

I'm going to be super verbose here to explain what's happening.

My assumption is that Hostgator has provided you with a file named malware.txt that contains entries that look like this:

The last method you mentioned -execute the clear operation- is the only one you should ever be using to clear an object store. Never delete files in .mule, unless you are absolutely sure they are corrupt and unrecoverable. That applies to any files in .mule. How do you invoke is up to you.

If you are talking about a development environment it may be ok to clean the environment, but don't try to do it in production to avoid losing data.

I think you are wrong with the cluster. The default object store configuration for Mule clusters is distributed memory. That means that the data is sincronized between nodes and it is not written to disk. That mean that if you reboot one node as a time the others will preserve the object store values, as the cluster is designed to do. You would need to shutdown all nodes at the same time to make it forget the object store.

< and > are shell metacharacters; you can't use them unquoted. The intention of the example in the manpage was that you replace with the hostname, not that you insert the hostname between the angle brackets:

The problem is with the Java segment, and the solution is to not only read the input stream, but also the output stream because the process will hang if both are not emptied. In order to do this properly, each stream needs to be read on a separate thread. ProcessBuilder is a better alternative because it allows you to combine the input and output stream into one and then only the main thread is necessary.

This stack post is a reference to the more canonical question for this concept: Java Process with Input/Output Stream

This obviously happens when you are hosting on a cPanel. You uploaded the env file attached to your code and left it at the root of your server. That is very illegal and exposed. But this is what I suppose happened. Your cPanel got hacked, the env file exposed and the script added, that script is probably sending illegal contents.

First of all, change your cPanel password, delete the AWS variables and look through your files for unexpected files. You can report the situation to your providers which is helpful if you do.

Secondly, move your public folder below the root folder and update the bootstrap.php file to locate the moved public folder. It's secured this way.

Lastly, I am not sure about any backdoors, but there are better hosting platforms, secure and Laravel dedicated. Forge, Fort Rabbit, etc. Add Heroku to the list but not Laravel dedicated hosting.

The env file is usually not included when deploying to production but it's obvious you can't ignore it while you host on cPanel.
