If you see file:///root/.aws/config anywhere in your logs, act as if your AWS keys are already public. Because in the cloud, every second counts. Want to test your own infrastructure? Run this curl command safely in a controlled environment to see if your server leaks files:
Consider encrypting the credentials file with tools like gpg or moving to a secrets manager (AWS Secrets Manager, HashiCorp Vault). In a 2022 incident, a bug bounty hunter found a parameter shared_file in a staging server that accepted base64-encoded strings. One string decoded to file:///root/.aws/config . The server returned the config file, which referenced a [prod] profile. The attacker then changed the path to /root/.aws/credentials and exfiltrated valid root keys. fetch-url-file-3A-2F-2F-2Froot-2F.aws-2Fconfig
Within 6 hours, the attacker spun up 200 GPU instances for crypto mining, resulting in a $50,000 bill before detection. The root cause? An internal dashboard using file:// to read local templates without sanitization. The string fetch-url-file-3A-2F-2F-2Froot-2F.aws-2Fconfig is not a random anomaly—it’s a digital distress signal. It indicates that either an attacker is probing for Local File Inclusion, or a developer inadvertently logged an attempt to read the most sensitive AWS configuration on a Linux system.
