# MAL-2026-4712: Malicious code in warp-contracts-plugin-deploy-test (npm)


- **Type:** Malicious package

## What is MAL-2026-4712?

MAL-2026-4712 is a malicious package in warp-contracts-plugin-deploy-test, published on 26 May 2026. 

### Official description

Package name `warp-contracts-plugin-deploy-test` mimics the legitimate `warp-contracts-plugin-deploy` and copies its public API surface (lib/cjs/index.js re-exports DeployPlugin, CreateContractImpl, SourceImpl, Arweave/Ethereum signers identical to the genuine package). package.json declares `"preinstall": "./bin/install-deps"` where `bin/install-deps` is a 976,568-byte packed Linux ELF binary (sha256 36abd242ddaa27f0160c539377a0e92cf781c1695137850acc87e3892b436d36). The package self-describes as a TypeScript Warp Contracts deploy plugin — there is no native source tree, no node-gyp/binding.gyp, no documented purpose for shipping a Linux ELF helper. Readable strings in the binary (LIBBPF, PTRACE, NETLINK_DIAG, HTTP/1.1, https://, USERPROFILE) are inconsistent with any deploy-plugin function and consistent with a host-implant payload. On `npm install`, the binary runs with the installer's privileges, executing attacker-supplied compiled code that the scanner cannot inspect.

This package was compromised as part of the IronWorm campaign. This campaign executes a malicious binary payload during installation via a preinstall hook. The payload is a Rust-built infostealer that targets developer environments, scanning for and harvesting credentials related to cloud providers, object storage, databases, source-control, package registries, and AI developer tools. It also targets cryptocurrency wallets, specifically injecting a malicious JavaScript hook into the Exodus desktop wallet to capture passwords and recovery phrases. Furthermore, the malware exhibits worm-like behavior by stealing GitHub and NPM credentials to push malicious updates to the victim's repositories and publish trojanized packages, and it uses an eBPF-based kernel rootkit to hide its processes and network connections on Linux systems.

## What should I do about MAL-2026-4712?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.

```text
MAL-2026-4712 is a malicious package: warp-contracts-plugin-deploy-test (npm). Every version was published to cause harm.

Task:
1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.
2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.
3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.
4. If the package is not used anywhere, say so and change nothing.
