DETECTION OVERVIEW
Risk Factors
Network environments that support a hybrid architecture of Amazon S3 (Simple Storage Service) and on-premise servers for data storage are common. An attacker with knowledge of Amazon S3 can download data from an S3 bucket to a compromised device for data staging. The business impact of this type of exfiltration is high because the attacker can steal sensitive data, which can lead to further attacks on your network.
The system might change the risk score for this detection.

An attacker that downloads sensitive data from an S3 bucket can stage data on a compromised device before exfiltration. A benefit of data staging is that the attacker can minimize the number of external connections needed to transfer all of the data, helping to evade detection.
Network analysis and visibility solutions remain underrepresented in enterprises. Find out why in this preview of a new Wave report.
