App store review processes catch most malware. But the bypass techniques that work reveal systematic gaps in mobile supply chain security.
Electron apps ship a full Chromium browser and Node.js runtime to the desktop. That means every web supply chain risk becomes a desktop attack surface — with elevated privileges.
Software-Defined Perimeters can isolate build systems, artifact repositories, and deployment pipelines from unauthorized access. Here is how SDP applies to supply chain security.
Fuzz testing discovers crashes, memory corruption, and logic errors by feeding random inputs to software. Applied to supply chain components, it reveals vulnerabilities that code review and static analysis miss.
When Conti's internal communications leaked in early 2022, they exposed the operational playbook of a top-tier ransomware gang — including how they targeted supply chains.
Relying too heavily on a single vendor creates systemic risk that most organizations dramatically underestimate. Here is how to measure and manage it.
When a supply chain attack hits, your DR plan needs to cover more than just infrastructure failover. Here is how to prepare for the worst.
