Security-related question about a possible exposed credential

[Emma-NYL]

Hello,

My name is Emma, I am conducting an academic study on possible credential exposure in public GitHub repositories.

While analyzing this repository, I found a string that may represent a credential. I'm including the code snippet below containing possible leakage. To avoid exposing sensitive information publicly, I marked the sensitive information.

Could you please help clarify whether the detected string is:

1. a real credential, or
2. a placeholder / example value?

Thank you for your time.

Code snippet (sensitive values masked):

The S3 storer puts the exported file into a bucket at a specified directory. Note, you shouldn't use your global AWS credentials for this. Instead, [create bucket specific credentials via IAM.](http://blogs.aws.amazon.com/security/post/Tx3VRSWZ6B3SHAV/Writing-IAM-Policies-How-to-grant-access-to-an-Amazon-S3-bucket)

    s3 := &barkup.S3{
      Region: "us-east-1",
      Bucket: "backups",
      AccessKey: "XXXX****XXXXX",
      ClientSecret: "XXXXXXXX****XXXXXXXXX",
    }

    err := someExportResult.To("data/", s3)

Region IDs

Thank you in advance for your time - I really appreciate it!

Sincerely,
Emma
