Which versions of SitеServer.Рlugin are malicious?

The following NuGet versions of SitеServer.Рlugin are flagged malicious: 2.4.0. Treat any of these as compromised.

How do I remediate SitеServer.Рlugin if I installed it?

Remove SitеServer.Рlugin 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 SitеServer.Рlugin — how do I know if it already compromised me?

If SitеServer.Рlugin 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.

Yes — SitеServer.Рlugin is associated with the RLMA-2024-03434, RLMA-2026-00024 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 SitеServer.Рlugin across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for SitеServer.Рlugin (version 2.4.0).
