There is build.rs, proc macros are unsandboxed, and lastly you install the binary so that you can run it. Even if the build and install were fully sandboxed, the binary could still do malicious stuff if ran.

Even without post-install script, a malicious payload could be hiding in some function and just wait until the developer invokes `cargo run`. Not that many people audit the crates they pull into their projects.

Yeah no shit, if you download malicious code from the internet and run it on your computer you will get pwned. No matter if it’s from a package manager a zip file or a submodule.

However the current npm vulns used a post install script.

		I maintain that NPM malware use postinstall scripts just because they exist and are convenient. Had NPM not had postinstall scripts, the malware would have used a different mechanism and been almost exactly as effective.
