kmf-i18nnpm
Advisory published Updated
kmf-i18n is a confirmed malicious npm package (MAL-2026-17747) that steals credentials and exfiltrates sensitive data (malicious versions 100.100.100, 100.100.101, 100.100.102). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in kmf-i18n (npm)
What this malware does
[email protected] is published with the version-number and behavior shape of a dependency-confusion reconnaissance beacon rather than an i18n library. The tarball ships a Linux x64 N-API binary at prebuilds/linux-x64/addon.node with no corresponding source, no binding.gyp, and no build step. package.json declares scripts.postinstall = "node postinstall.js", and postinstall.js require()s that prebuilt.node binary, so the native code is loaded automatically on npm install. The addon opens a raw TCP socket to the hardcoded bare IP 64.181.165.115 on port 80 and sends an HTTP/1.0 POST to /dc with body h=<HOSTNAME>&p=<npm_package_name>&u=<unused>&r=<npm_config_registry>, reading those values from the installer's environment. The exfiltrated npm_config_registry value discloses internal/private npm registry URLs, which is the characteristic signal of dependency-confusion target reconnaissance. The addon exposes no i18n functionality consistent with the package's declared purpose; its only observable behavior is the install-time beacon. The main entry also require()s the same binary, so merely importing the package re-triggers the native load path.
The OpenSSF Package Analysis project identified 'kmf-i18n' @ 100.100.102 (npm) as malicious.
It is considered malicious because:
- The package communicates with a domain associated with malicious activity.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for kmf-i18n (3 malicious versions).
If you installed it — respond
kmf-i18n 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 kmf-i18n 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 kmf-i18n-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
