wie888rnpm
Advisory published Updated
wie888r is a confirmed malicious npm package (MAL-2026-17707) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.1, 1.0.0, 1.0.1…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in wie888r (npm)
What this malware does
[email protected] ships a stub main (index.js) that exports a Proxy returning no-op functions for any property access, so bundlers that resolve this name do not crash. The package's postinstall script runs beacon.cjs, which collects host identifiers (hostname, install path, cwd, node version) and POSTs them to the hardcoded bare-IP endpoint http://185.158.107.175:8787/_ah/dc over plain HTTP. index.js invokes the same beacon on require, so the exfiltration fires both at install time and whenever the module is loaded. The destination is not a documented first-party service, and the package's self-described 'compatibility shim' purpose is contradicted by the beacon behavior. The combination of a no-op Proxy stub, a hardcoded non-publisher bare-IP endpoint, and dual install-time plus import-time reconnaissance is the standard shape of a dependency-confusion / typosquat probe used to confirm resolution of an unexpected name inside a target environment.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for wie888r (8 malicious versions).
If you installed it — respond
wie888r is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If wie888r 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.

Detect & block this
O3 blocks wie888r-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
