The malicious versions were live for 86-107 minutes before removal; the Rust Security Response Team unyanked earlier safe versions and advises pinning arrayref at 0.3.9 or earlier, with no patched version or CVE assigned yet. RustSec advisories state no evidence of actual usage of the malicious versions. Why: If you build Rust projects, check ~/.cargo/registry/cache for the deleted crate files and pin arrayref to 0.3.9 or earlier immediately—the attack executed at build time, meaning merely compiling an affected project was enough to run the payload without calling any crate function. This also highlights that maintainer account compromise remains a weak link in supply chain security regardless of language ecosystem. security supply-chain rust build-time-attack
