🛡️ RUSTSEC-2026-0027 — tracings

tracings was removed from crates.io for malicious code

This is part of an ongoing campaign to attempt to typosquat crates in an

attempt to exfiltrate Polymarket credentials.

The malicious crate had 1 version published on 2026-02-26 approximately 9 hours

before removal and had no evidence of actual usage. The only crate depending on

this crate was the tracing_checks crate, which was also part of this campaign

and has received a separate advisory.

Thanks to Marko Ćupić for finding and reporting this to the Rust security

response working group, and to Emily Albini for co-ordinating with the

crates.io team.

The crates.io team advises anyone developing with Polymarket to review

dependencies carefully. We are investigating ways to mitigate this attacker who

appears to be very motivated to steal Polymarket credentials.
