Introducing Organization Notifications in Socket

Key Takeaways

• Socket has launched Organization Notifications to provide batched, organization-level alert updates via email.
• Users can subscribe to specific alert lifecycle events: created, changed, and cleared.
• Alerts can be filtered by category (e.g., Supply chain risk, Vulnerability), severity, priority, and repository to reduce noise.
• Updates are batched and sent at most once every 20 minutes to prevent inbox fatigue.
• Sample alerts detected by Socket include arbitrary code execution in npm protobufjs, ReDOS in semver-regex, and prototype pollution in minimist.

Affected Systems

• Socket platform (Team, Business, and Enterprise plans)
• npm protobufjs (Example vulnerability)
• npm semver-regex (Example vulnerability)
• npm @fastify/static (Example vulnerability)
• npm minimist (Example vulnerability)
• npm is-obj (Example unmaintained package)

Detection Availability

• YARA Rules: No
• Sigma Rules: No
• Snort/Suricata Rules: No
• KQL Queries: No
• Splunk SPL Queries: No
• EQL Queries: No
• Other Detection Logic: No

N/A

Detection Engineering Assessment

EDR Visibility: None — This is a product feature announcement regarding alerting capabilities, not a threat report detailing endpoint behavior. Network Visibility: None — This is a product feature announcement, not a threat report detailing network indicators. Detection Difficulty: N/A — Not applicable to product announcements.

Hunting Hypotheses

Hypothesis	Telemetry	ATT&CK Stage	FP Risk
Monitor for the introduction of known vulnerable npm packages (e.g., protobufjs, minimist, semver-regex) into the CI/CD pipeline or developer environments to identify potential supply chain risks.	Software Composition Analysis (SCA) logs, CI/CD pipeline build logs	Initial Access	Low

Recommendations

Immediate Mitigation

• Configure Socket Organization Notifications to route critical supply chain and vulnerability alerts to the appropriate security team inbox.

Security Awareness

• Train development teams on the importance of addressing high and critical severity alerts surfaced by SCA tools, such as prototype pollution or arbitrary code execution vulnerabilities in npm packages.
