Overview

In a recent discussion, Chris Boehm from Zero Networks emphasized the risks associated with vendor relationships in cybersecurity. He pointed out that attackers are increasingly targeting the subcontractors of trusted vendors, which can lead to significant breaches. When a vendor's vendor is compromised, attackers can gain access to your systems using stolen credentials from these lesser-known companies. This situation highlights the need for organizations to vet not only their direct suppliers but also their supply chain partners. The implications are serious, as a breach could allow unauthorized access to sensitive data without the primary vendor even being aware of the risk. Companies should reassess their security protocols to include these indirect relationships to better protect their systems.

Key Takeaways

Affected Systems: Vendor's vendors, subcontractors, third-party services
Action Required: Companies should implement stricter vetting processes for all vendors and their subcontractors, and regularly review access credentials.
