Episode 48 — Differentiate Supply Chain Attacks: Vendor Breach, Dependency Poisoning, and Trust
Supply chain attacks exploit transitive risk by targeting third-party partners and software components to gain a foothold in an organization. A vendor breach occurs when an adversary leverages the infrastructure or credentials of a trusted provider to enter your network directly, while dependency poisoning involves tampering with software libraries or updates during the build process. Trust abuse is a broader category where attackers exploit existing business relationships or remote access tunnels that were left open after a project's conclusion. For the exam, you must monitor for early signals such as unexpected modifications to binary hashes or unusual login attempts from partner service accounts. Best practices involve implementing a Zero Trust (Z T) model for external integrations and maintaining the ability to rapidly isolate vendor connections during an anomaly. Coordination with partners requires structured questions and a demand for hard forensic evidence rather than relying on verbal assurances.
