TL;DR: 2024 cyber incidents exposed a "silent breach" pattern in which third-party weaknesses, ransomware and exploited vulnerabilities in tools such as Cleo and Snowflake created cascading disruption across connected ecosystems, according to Black Kite. The lesson for identity and access teams is that vendor trust, token scope and offboarding are now operational controls, not just procurement concerns.
Editorial analysis by NHI Mgmt Group, based on content published by Black Kite: “2024 Cyber Incidents: Supply Chain Disruptions and Vulnerabilities”.
Key questions
Q: What breaks when third-party access is excluded from privileged access reviews?
A: Auditability breaks first, followed by entitlement accuracy and offboarding discipline.
A: Third party breaches create outsized impact because vendors often hold concentrated, high value data for a narrow business function and may have broad access to records that the customer cannot fully inspect.
Q: What are the signs that vendor access is becoming a hidden risk?
A: Look for shared credentials across multiple services, stale integrations that no one owns, broad OAuth consent, and supplier accounts that have not been reviewed after business changes.
Practitioner guidance
- Map every third-party trust path Document SaaS integrations, APIs, service accounts and delegated tokens that can reach sensitive systems or data.
- Reduce vendor permission scope Remove broad entitlements from supplier accounts and replace them with narrowly scoped access tied to specific business workflows.
- Add revocation triggers for supplier compromise Define who can disable external access, how quickly it happens and which systems are cut off when a vendor incident is confirmed.
Bottom line: Third-party compromise can stay hidden inside trusted relationships until it cascades across connected systems and business units.
