Salesforce OAuth Exfiltration: The Growing Threat Landscape and How to Mitigate It
As threat actors continue to exploit vulnerabilities in Salesforce's OAuth system, it has become increasingly important for organizations to implement robust security measures to protect sensitive data. Learn how to detect and mitigate these threats with advanced authentication boundary controls, defense-in-depth strategies, and enhanced logging and detection capabilities.
Threat actors are exploiting vulnerabilities in Salesforce's OAuth system for malicious purposes. The attacks use tactics such as elevated permissions, lateral movement, and persistence to gain unauthorized access. Social engineering tactics like phishing or pretexting are also used to trick users into divulging sensitive information. Organizations must implement advanced security measures to detect and mitigate these threats. The recommended security measures include enhanced authentication boundary controls, defense-in-depth strategies, and identity detection and response capabilities. Techniques for detecting and preventing Salesforce OAuth exfiltration include implementing advanced logging and detection controls, utilizing Salesforce's built-in security features, and enforcing granular data access policies.
Salesforce, one of the leading Customer Relationship Management (CRM) platforms used by numerous organizations worldwide, has become a focal point for threat actors seeking to exploit vulnerabilities in its OAuth system. The recent surge in Salesforce OAuth exfiltration attacks highlights the importance of implementing robust security measures to protect sensitive data within the platform.
The context data provided sheds light on the tactics, techniques, and procedures (TTPs) employed by attackers to leverage Salesforce's OAuth system for malicious purposes. By exploiting this vulnerability, threat actors can gain unauthorized access to sensitive data, exfiltrate it, and potentially pivot to other cloud platforms such as Okta or Microsoft 365.
The TTPs used in these attacks include elevated permissions, lateral movement, and persistence within the Salesforce environment or to other cloud platforms. Additionally, attackers often use social engineering tactics, such as phishing or pretexting, to trick users into divulging sensitive information or granting unauthorized access.
To detect and mitigate these threats, organizations must prioritize implementing advanced security measures, including:
1. Enhanced authentication boundary controls, which establish a foundational layer of trust based on network context.
2. Defense-in-depth strategies, which layer multiple security measures, such as strong authentication, device compliance checks, and session controls.
3. Identity detection and response capabilities, which integrate real-time threat intelligence into access decisions.
Specifically, organizations can employ the following techniques to detect and prevent Salesforce OAuth exfiltration:
1. Implementing advanced logging and detection controls, including Real-Time Event Monitoring (RTEM) streaming and viewing.
2. Enabling critical log types in the organization's Salesforce environment and ingesting them into a Security Information and Event Management (SIEM).
3. Utilizing Salesforce's built-in security features, such as Shield and the Event Monitoring Add-On.
To further enhance security, organizations can consider implementing granular data access policies, including:
1. Enforcing "Private" Organization-Wide Sharing Defaults (OWD) for all sensitive objects.
2. Leveraging Restriction Rules for Row-Level Security to fine-grain control over which records a user can see.
3. Requiring strict timeouts on any Salesforce support access grants.
By implementing these measures, organizations can reduce the risk of falling prey to Salesforce OAuth exfiltration attacks and protect their sensitive data within the platform.
