AWS - Download Current Site With User Content - amazon-web-services

Is there a way to download the current site content, namely, the uploaded user images, from a web application on AWS? Everything I have found only gives access to previous code deployments, which do not include the user uploaded files.
I have tried the instructions here but it only seems to give access to the code as it was at the time of deployment.
Thank you for any help.

User uploaded images are usually stored in Amazon's S3 service, so go to your AWS dashboard and navigate to the S3 section, and you should find the files in a bucket there

Are you trying to download your own website ? Then you need to get not just code or user images; but also database containing data. You need to check the code where images are saved.. Are they on local EBS or EFS or S3 and correspondingly copy from there.
If you are trying to download some-one else website. Then surely you will not have access to database or code or other user images; but still you can download full website as seen to the public using many tools like WinHTTrack.

how do you stop downloads from AWS S3 with the object url

i have a website similar to video hosting where i need to display upload videos and images and have the images be visible and also the videos if they are purchased, however their locations are saved in the database (MongoDB) and are displayed on the web-page and therefore show up in the network tab in the developer console.
this means that if you click on the link e.g. "https://s3.Region.amazonaws.com/bucket-name/key-name/folder/file-name.mp4" it will auto download, this only happens on chrome though but not Firefox where it just displays the object with no download option. i have tried to change the bucket policy, add encryption but either that causes the images that i want to display to become invisible as they are not publicly accessible or just has no effect and still allows for the video to be downloaded. is there any way for me to have the images and videos in the same bucket and have them both be visible under the right circumstances but block access to the bucket and prevent them from being downloaded by anyone but the bucket owner?
You cannot stop the downloads because the ability to show videos and images in a browser also means that the files are accessible via URL (that's how the browser fetches them).
One option is to use an Amazon S3 pre-signed URL, which is a time-limited URL that provides temporary access to a private object. The way it would work is:
Users authenticate to your back-end service
When a user requests access to one of the videos or images, your back-end checks that they are authorized to access the file
If so, your back-end generates an Amazon S3 pre-signed URL and includes it in the web page (eg <img src='...'>)
When the user's browser accesses that URL, Amazon S3 will verify that the URL is correct and the time-limit has not expired. If it's OK, then the file is provided.
Once the time limit expires, the URL will not work
This will not prevent a file being downloaded, but it will limit the time during which it can be done.
Alternate methods would involve serving content via streaming instead of via a file, but that is a much more complex topic. (For example, think about how Netflix streams content to users rather than waiting for them to download files.)

Only allow access to S3 objects from website

Is it possible to only allow access to images in an S3 bucket via a specific website?
I'm trying to prevent users from being able to access the image directly in the browser to prevent them from being able to download the images for free, but I need my website to be able to load them so they can see a preview.
I went through this tutorial step-by-step, but it still didn't work properly:

If you want a preview feature you may need to consider saving 2 images
Public Image that is Pixilated / Watermarked
An authorized image with some authentication aolution like Cognito

How to restrict users from download files uploaded to aws s3

I am developing a LMS in Laravel and uploading all the video files to aws s3 bucket and can play them using video js player. But problem is, users can download the video files, which I want to stop. Can anybody suggest me is it possible or not? If possible, can anyone tell me how can I do that?
Objects in Amazon S3 are private by default.
However, if you wish students to make use of a file (eg a learning course video), you will need to grant access to the file. The best way to do this is by using Amazon S3 pre-signed URLs, which provide time-limited access to a private object.
For example, the flow would be:
A students logs into the LMS
A student requests access to a course
The LMS checks whether they are entitled to view the course (using your own business logic)
If they are permitted to use the course, the LMS generates a pre-signed URL using a few lines of code, and returns the link in a web page (eg via an <a> tag).
The student can access the content
Once the expiry duration has passed, the pre-signed URL no longer works
However, during the period where the student has access to the file, they can download it. This is because access has been granted to the object. This is necessary because the web browser needs access to the object.
The only way to avoid this would be to provide courseware on a 'streaming' basis, where there is a continuous connection between the frontend and backend. This is not likely to be how your LMS is designed.

How can I grant access only if resource is accessed through my domain?

I have a bunch of videos and all of them are uploaded on Wistia. On Wistia, I have set up access for my domain, so they will play only when the videos are fetched from my domain.
If someone uses View Source and copies the video URL and pastes it in a separate browser window, they get an "access denied' message.
I'm thinking about moving my videos to Google Cloud Storage. So, my questions are:
Does Google cloud provide a similar domain restriction feature?
How can I set this up? For now, I've created a temporary bucket and uploaded a video and granted it public access. Then I copied the public link of the MP4 file and added to my website, and it obviously plays, but then any paid member can use View Source, copy the MP4 link and upload it to other streaming services for everyone to see.
EDIT
Is there a way to do this programmatically - like my website is in PHP - so something along the lines like - keep the bucket as restricted access and then through PHP - pass some key and retrieve the video file. Not sure if something like this is possible.
Thanks
I do not believe that there is an access control mechanism in Google Cloud Storage equivalent to the one you are using in Wistia.
There are several methods to restrict object access (see https://cloud.google.com/storage/docs/access-control) in GCS, but none of them are based upon where the request came from. The only one that kind of addresses your issue is to use Signed URLs. Basically, a user would go to your site, but instead of giving them the "real" URL of the object they are going to be using, your application retrieves a special URL that is time-limited. You can set the length of time it is valid for.
But if what you are worried about is people copying your video, presumably they could still see the URL someplace and copy the data from there if they did it immediately, so I don't think that really solves your problem.
Sorry I can't be more helpful.

Is there anyway to make the URL of an object in my AWS S3 bucket inaccessible?

I have some images on my website that are loaded in via S3 however I want to make those URL's private/inaccessible without compromising the visibility of the image on my site.. Is this possible?
When I make the URL of the object private like so:
It addresses me with the following page upon attempting to view it:
I am fairly new at S3.. Any suggestions?
No. If the S3 URL is embedded in your page, then the client has to be able to read the file from S3, which means it needs to be public. S3 is no different from any other web resource in that way.
