Rust crate shinchina malicious code in build environment telemetry

Severity: info · Published 2026-11-06

A Rust library package named shinchina was removed from crates.io after being found to contain malicious code. The compromised package attempted to exfiltrate build environment data to an attacker-controlled server during the build process. Although the package was published in March 2025 and left available for approximately 20 months, there was no evidence of widespread adoption, limiting real-world impact.

Vendors: crates.io.
