The following npm versions of @spot-dapp/web are flagged malicious: 99.99.9, 99.99.99. Treat any of these as compromised.

How do I remediate @spot-dapp/web if I installed it?

Remove @spot-dapp/web 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 @spot-dapp/web — how do I know if it already compromised me?

If @spot-dapp/web 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 @spot-dapp/web part of a known attack campaign?

Yes — @spot-dapp/web is associated with the RLMA-2026-01060 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
