 Developers frequently leave versions unpinned or allow wide ranges. When a resolver is configured with both internal and public indexes, it may select the newest version regardless of source. For internal names like `requests-company`, if the internal index has `1.0.1` but an attacker publishes `1.0.2` to the public registry and your resolver considers both, the public package may win.
 
+### Related pattern: `npx` binary/package-name confusion
+
+`npx <name>` is also a **name-confusion execution sink**. If no explicit `--package` is provided, npm first tries to resolve `<name>` as a binary from the local `node_modules/.bin`, global bins, local/global installed packages, and the npx cache. If none of those checks succeed, npm treats the original binary name as the package name, installs it into `~/.npm/_npx/<hash>/`, prepends that cache's `node_modules/.bin` to `PATH`, and executes it. In CI or non-TTY contexts, npm assumes `--yes`, so the install path is even easier to reach automatically.
+
+Why this is exploitable:
+- **Binary names and package names do not need to match.** A command may be `binary_name` while the real package is `@company/package-name`.
+- **Scoped/private packages increase the gap.** The package can be scoped, but the exposed `bin` name is unscoped.
+- **Exploitability is context-dependent.** `npx binary_name` may be safe inside the project root where the real binary exists, but unsafe in CI, in a clean workspace, outside the repo root, or in agent automation where `node_modules/.bin` is absent.
+
+Typical recon sources:
+- `package.json` scripts containing `npx <binary>`
+- READMEs and onboarding docs
+- CI/CD workflows
+- bundled manifests leaked in frontend assets
+- AI-agent tool definitions that shell out through `npx`
+
+Practical abuse pattern:
+1. Find `npx <binary_name>` where the intended tool actually comes from another package.
+2. Check whether `<binary_name>` exists as a public npm package.
+3. If the public name is unclaimed, register it and expose the expected command via the package `bin` field.
+4. Wait for execution in a context where the legitimate local binary is missing; npm will fetch the attacker-controlled package into `~/.npm/_npx/` and run it.
+
+Defensive notes specific to this pattern:
+- Prefer **explicit package resolution**: `npx --package=@company/package-name binary_name` or `npm exec --package=@company/package-name -- binary_name`.
+- Claim public npm names that match internal/private binaries, especially for scoped packages.
+- Treat CI/non-TTY warnings about missing packages that "will be installed" as security events.
+- Monitor unexpected cache installs under `~/.npm/_npx/`.

 ### Related pattern: compromise of a legitimate package release
 
 Dependency confusion is not the only way to get install-time execution. If an attacker compromises the maintainer account or publishing token of a legitimate package, they can publish a malicious version of the real package and obtain code execution on every machine that installs it.
