Understanding the Bucket Hijacking Threat in Cloud Storage
In July 2026, a critical cloud storage attack technique known as 'bucket hijacking' was disclosed, enabling threat actors to silently redirect an organization's active cloud data streams, including audit logs and telemetry, into attacker-controlled external storage buckets across major cloud platforms. This vulnerability exploits the global uniqueness of cloud storage bucket names, allowing attackers to register a previously deleted bucket name and reroute data streams intended for the original bucket. The attack affects major cloud providers, including Google Cloud, Amazon Web Services (AWS), and Microsoft Azure, and detection is extremely challenging once deployed.

As cloud environments become increasingly complex, the potential for such vulnerabilities to be exploited grows, emphasizing the importance of proactive security measures to safeguard sensitive data.
