@@ -14,9 +14,9 @@ For more information about Macie check:
AWS Macie is a security service that automatically detects sensitive data within AWS environments, such as credentials, personally identifiable information (PII), and other confidential data. When Macie identifies a sensitive credential, such as an AWS secret key stored in an S3 bucket, it generates a finding that allows the owner to view a "sample" of the detected data. Typically, once the sensitive file is removed from the S3 bucket, it is expected that the secret can no longer be retrieved.
However, a **bypass** has been identified where an attacker with sufficient permissions can** re-upload a file with the same name** but containing different, non-sensitive dummy data. This causes Macie to associate the newly uploaded file with the original finding, allowing the attacker to use the **"Reveal Sample" feature** to extract the previously detected secret. This issue poses a significant security risk, as secrets that were assumed to be deleted remain retrievable through this method.
