ShutterGap: Aryon Security Finds 3.7 M AWS Resources Publicly Exposed Beyond CSPM Visibility
What Happened — Aryon’s ShutterGap research identified 3,731,699 short‑lived AWS resources that were publicly accessible for minutes or hours before traditional CSPM/CNAPP tools could detect them. The exposures stem from customer‑controlled public‑sharing settings and often contain highly sensitive data.
Why It Matters for Compliance & Audit Readiness
- SOC 2 requires documented configuration‑management controls (CC6.1, CC6.2) and continuous monitoring; a “find‑and‑remediate later” model leaves a gap that attackers can exploit.
- Proactive enforcement of AWS Service Control Policies (SCPs) provides the preventive control evidence auditors look for, turning a reactive scan into a continuous compliance control.
- Verisq’s Control Mapping capability lets you map SCPs to SOC 2 criteria and automatically collect audit‑ready evidence of enforcement.
Who Is Affected — Any organization that runs workloads on AWS services that support public sharing (e.g., S3 buckets, EBS snapshots, AMIs). Large, multi‑account cloud environments are especially at risk.
Recommended Actions
- Deploy resource‑specific SCPs that block public‑sharing configurations by default.
- Integrate real‑time configuration enforcement into CI/CD pipelines and IAM policies.
- Augment periodic CSPM scans with event‑driven monitoring that captures short‑lived resources for audit evidence.

Technical Notes – The exposure window is measured in minutes to hours, far shorter than the typical CSPM scan cadence. No AWS vulnerability is involved; the issue is purely a customer‑misconfiguration under the shared‑responsibility model. Sensitive data observed includes private logs, credentials, and proprietary code.
