If an attacker successfully exfiltrates this file, they can impersonate the compromised user or service. Depending on the permissions (IAM policies) attached to those keys, an attacker could: Steal or delete sensitive data from S3 buckets. Launch expensive EC2 instances for crypto-mining. Modify security groups to create further backdoors. Gain full administrative control over the AWS account. How the Vulnerability Manifests
