Which versions of Соstura.Fоdу are malicious?

The following NuGet versions of Соstura.Fоdу are flagged malicious: 5.8.0-alpha0098. Treat any of these as compromised.

How do I remediate Соstura.Fоdу if I installed it?

Remove Соstura.Fоdу from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed Соstura.Fоdу — how do I know if it already compromised me?

If Соstura.Fоdу was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is Соstura.Fоdу part of a known attack campaign?

Yes — Соstura.Fоdу is associated with the RLMA-2024-02774, RLMA-2026-00005 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find Соstura.Fоdу across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for Соstura.Fоdу (version 5.8.0-alpha0098).
