Unable to see S3 Buckets List in AWS management console Getting Error "You don't have permissions to list buckets"
When I try to view the buckets list in AWS, I am getting this error,
I have started facing this issue first time. Before that, I was successfully able to view buckets list and perform all operations on the buckets. I have also tried to analyse what permissions I have and i have seen that I am a member of admin group that gives me access to all the services on AWS as can be seen in the following images but still I am unable to view the buckets. Can anyone guide me about this issue. Thanks

Any Deny statements override Allow statements, so the best approach is to go hunting for them. In this case your policies include AWSCompromisedKeyQuarantineV2 which contains:

Hello, Please check the S3 bucket policy too. If a user wants to use the AWS Management Console to view buckets and the contents of any of those buckets, the user must have the s3:ListAllMyBuckets and s3:GetBucketLocation permissions. for example { "Id": "Policy1686696361193", "Version": "2012-10-17", "Statement": [ { "Sid": "Stmt1686696358634", "Action": [ "s3:GetBucketLocation", "s3:ListAllMyBuckets" ], "Effect": "Allow", "Resource": "*", "Principal": { "AWS": [ "arn:aws:iam::1111222333444:group/mygroup" ] } } ] }

Thanks for the reply. Yes, you are right. This policy "AWSCompromisedKeyQuarantineV2" has limited my access due to which I can not view buckets in S3 service but the problem is that this policy has also limited my access to the IAM due to which I can not remove this policy from my user. Can you guide me in this regard? Thanks
Please have a look at https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSCompromisedKeyQuarantineV2.html - your access has been limited for a reason. As it says there, "Do NOT remove this policy. Instead, please follow the instructions specified in the support case created for you regarding this event.".
Hi, I have tried to follow the instructions. Instruction say that i have to create new access key and i should delete the old one before removing this policy but the problem is that I do not have now permissions to do these steps because this policy has been attached to my user.
The AWSCompromisedKeyQuarantineV2 policy prevents someone with access to the compromised access-key being able to do any damage, including being able to remove the policy to re-enable full access. So your IAM User with this policy can't be used to fix it up, is has to be done from another IAM Principal with appropriate permissions.
