TL;DR: Third-party weaknesses in 2024 cyber incidents, Black Kite reports, created cascading disruption across connected ecosystems through ransomware and exploited vulnerabilities in tools such as Cleo and Snowflake. Supplier access now has to be governed as an identity control, or hidden trust paths can widen blast radius.
Editorial analysis by NHI Mgmt Group, based on content published by Black Kite: “2024 Cyber Incidents: Supply Chain Disruptions and Vulnerabilities”.
Key questions
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.
Q: What breaks when third-party access is excluded from privileged access reviews?
A: Auditability breaks first, followed by entitlement accuracy and offboarding discipline.
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.

The silent breach is fundamentally an identity governance problem, not just a vendor risk problem. When third parties retain access through integrations, service accounts or delegated permissions, the real control question is who can act on behalf of whom and for how long. That makes the lifecycle of access as important as the vulnerability itself. Organisations that treat supplier access as static trust are building in latent exposure, especially where OAuth app governance has never been tied to offboarding discipline.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should organisations respond when a supplier incident is disclosed?
A: Contain the reachable access first, not just the compromised account. Disable or restrict the supplier tokens, service accounts and integrations that can reach critical systems, then verify whether the same trust path exists elsewhere in the environment. The response goal is to stop propagation before the compromise spreads through connected workflows.
