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.

## Technical details

The shinchina Rust crate contained code that attempted to send telemetry from the build environment to an arbitrary remote URL, representing a supply-chain attack vector. The crate had no upstream dependencies on crates.io, and was published once in version 0.0.0-0 on 2025-03-01 before removal. No patched versions exist; removal from the registry is the only remediation.
