Summary
Malicious code in strath (npm)

The package declares a postinstall script that runs dist/config.js. That script fetches JSON from https://my-api.trade-api.workers.dev?id=2 and then executes globalThis[data.success](data.id), where both the method name and its argument are supplied by the remote server. This gives the operator of that endpoint arbitrary code execution on any machine that runs npm install strath — the invocation fires automatically as part of the default install lifecycle. The behavior is unrelated to the package's advertised path-utility purpose. The same script also references globalThis[tag](text) with undefined identifiers, consistent with a deliberately opaque dropper shape rather than a normal build step.
