# MAL-2026-4714: Malicious code in wdb-sdk (npm)


- **Type:** Malicious package
- **Package:** `wdb-sdk` (npm)
- **Published:** 26 May 2026

## What is MAL-2026-4714?

MAL-2026-4714 is a malicious package in wdb-sdk, published on 26 May 2026. 

### Official description

package.json declares `"preinstall": "./dist/runtime.node"`, causing npm to spawn the shipped file as an executable on every install on Linux. Despite the `.node` extension (which would normally indicate a Node-API addon loaded via `require()`), the file is a 976KB stripped/packed ELF binary, not a native addon — Node addons are never spawned as processes. The binary contains strings indicating network I/O (HTTP/1.1, POST, https://), host enumeration (USERPROFILE, /lib64, linux-x86), kernel/eBPF and ptrace primitives (LIBBPF_0.0, PTRACE), and modern crypto (RSA/Ed25519/X448/MLKEM), with packed/obfuscated fragments. The package ships no source, no binding.gyp, no node-gyp/prebuild-install/node-pre-gyp scaffolding, no checksum, and no version-pinned publisher-hosted release URL — none of the legitimate native-addon shape. The `.node` filename is a deliberate disguise to make the executable look like a benign addon. Any developer or CI system running `npm install wdb-sdk` on Linux executes this attacker-controlled binary with the installer's privileges.

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-2026-4714?

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

## Fix prompt for AI coding agents

```text
MAL-2026-4714 is a malicious package: wdb-sdk (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.
