Microsoft Self-Service Password Reset abused in Azure data theft attacks
Summary
Threat actors are exploiting Microsoft's Self-Service Password Reset (SSPR) feature within Azure to steal sensitive data from production environments. These attacks leverage legitimate applications and administrative tools, making them difficult to detect. The compromised data includes customer information and other sensitive details.
IFF Assessment
The exploitation of legitimate administrative features for data theft represents a significant threat to organizations and defenders.
Defender Context
Defenders should be aware of how legitimate administrative features like SSPR can be abused by attackers to exfiltrate data. Implementing robust logging, monitoring, and anomaly detection around SSPR usage and other administrative functions is crucial. Organizations should also review access controls and consider implementing multi-factor authentication even for internal administrative processes.
