Which versions of solidity-abi are malicious?

Every published version of solidity-abi on npm is considered malicious. Remove the package entirely.

How do I remediate solidity-abi if I installed it?

Remove solidity-abi 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 network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is solidity-abi part of a known attack campaign?

Yes — solidity-abi is associated with the GHSA-4pr4-9j3x-h243 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect solidity-abi in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking solidity-abi and packages like it before any post-install script runs.

What this malware does

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
