- Description: A packaged set of code libraries and tools that developers bundle into their apps to add functionality such as ads, analytics, payments or measurement.

A code module a developer drops into their app so they don't have to build everything from scratch. Ad SDKs, analytics SDKs, measurement SDKs. Many apps carry several. Each one runs with the app's permissions, and the developer rarely sees everything it does in the background. That is the supply chain risk. One bad SDK bundled into hundreds of apps can turn every device those apps run on into a proxy exit node.
