Summary

Hide ▲

The five malicious Rust crates on crates.io were published between late February and early March 2026 and operated as a supply-chain infostealer. They masqueraded as time-related utilities while collecting .env secrets from developer workspaces and CI jobs. Stolen data was sent to threat actor-controlled infrastructure through the lookalike domain timeapis[.]io. The activity matters because API keys, tokens, and other secrets in build environments can enable deeper compromise.

    Researchers disclose five malicious Rust crates stealing .env secrets

    Initial Disclosure

    Researchers disclosed five malicious Rust crates on crates.io—chrono_anchor, dnp3times, time_calibrator, time_calibrators, and time-sync—that impersonated timeapi.io, used the lookalike domain timeapis[.]io to exfiltrate .env secrets from developer environments and CI jobs, and hid additional exfiltration logic in chrono_anchor through guard.rs without establishing service or scheduled-task persistence.
