I did a stupid thing. In my s3 bucket I changed object onwership to 'ACLs disabled' and added s3 bucket policy to deny all resources and for all users..
Now I haven't access to list, permissions and even can't change bucket policy.
Is any options to revert it?
s3 denied
I was looking for this s3 policy in IAM policy but I haven't found it.
I found only this policy with arn to this bucket, but it seems this policy doesn't work

I keep seeing posts that refer to setting a policy and while they mention S3 buckets the policy they are often referring to are IAM policies.
In my case I want to control access to my S3 bucket only by an actual "S3 bucket policy".
My current path is :::mybucket, which has /thing1/ and /thing2/
If I wanted a bucket policy that allows a CLI user the ability to list and get /thing1/* but not /thing2/* how would this be done? I've tried my policy with all kinds of conditions, paths etc but nothing seems to work...
I have created an Amazon S3 bucket with an IAM Role that has full S3 bucket permissions.
When I check the bucket policy it is written that I have these policies:
list object
write object
read bucket permission
write bucket permission
But when it came to removing an object for this bucket an "Access Denied" error is thrown without any other description.
To delete an object in Amazon S3, you require the s3:DeleteObject permission.

I recently created an S3 bucket on AWS through the console, with the default settigns (except the name, obviously). I try editing the Bucket Policy, but getting this error: "Error Access denied", both with my admin IAM user, and the root account.
How can I get access to edit S3 Bucket policies?
Answering my own question: by default, buckets have the following option set: "Block new public bucket policies". Turning this off will enable updating the Bucket Policy.
I always get confused in two but I wanted to add a IAM policy on S3 bucket.
Basically I have created an output bucket for Amazon transcriptions but it seems I need to add IAM role to allow Transcription job to write to the bucket. I think if I can attach AmazonTranscribeFullAccess to S3 bucket, it will work but I am unable to attach this policy. Could you please advise how can I add this policy on the new bucket?
There are a few concepts you will want to dig deeper into to understand the difference between IAM policies and S3 bucket policies. A detailed guide is: https://docs.aws.amazon.com/AmazonS3/latest/dev/how-s3-evaluates-access-control.html
You can attach IAM policies to Users, Groups and Roles, and you can attach bucket policies to S3 buckets.
Try adding S3 access to the user/role that you are using to run the transcribe job.
I have an S3 bucket with policy1 attached to it and i attached another policy2 to same S3 bucket via cloudformation but its not showing up in S3 bucket properties => permissions => edit bucket policy.
can a AWS S3 bucket have more than one policy attached to it?
No, a AWS::S3::BucketPolicy can only have one PolicyDocument. However, a PolicyDocument can have multiple Statements.
