Cloud Bucket Hijacking Enables Silent Data Exfiltration Across Major Platforms

A new attack technique known as cloud bucket hijacking has been identified, affecting major cloud service providers including AWS, Google Cloud, and Microsoft Azure. This method allows attackers to silently redirect active data streams, such as audit logs and telemetry, to external storage controlled by the attackers. The vulnerability stems from a fundamental architectural flaw shared across these platforms, posing significant risks for organizations relying on cloud storage. Security researchers have confirmed the technique's effectiveness, raising alarms about potential data breaches and loss of sensitive information. Organizations are urged to assess their cloud configurations and monitor for unusual data redirection activities. The full scope of the impact remains under investigation, but the potential for widespread exploitation is evident.

Key Points: • Cloud bucket hijacking allows silent redirection of data streams to attacker-controlled storage. • Major cloud providers affected include AWS, Google Cloud, and Microsoft Azure. • Organizations are advised to review cloud configurations to mitigate risks.
