tempo-shared-modulesnpm
Advisory published Updated
tempo-shared-modules is a confirmed malicious npm package (MAL-2026-4688) that steals credentials and exfiltrates sensitive data (malicious versions 99.0.0, 99.0.1, 99.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in tempo-shared-modules (npm)
What this malware does
On npm install, the preinstall script poc.js collects host identity (hostname, username, OS/platform), network configuration (ipconfig / ip a / resolv.conf), git remote, the parent project's package.json, CI configuration files (.gitlab-ci.yml,.github/workflows, Jenkinsfile, azure-pipelines.yml), and bulk-scrapes process.env for any variable name matching TOKEN, AWS, AZURE, NPM, GITHUB, GITLAB, CI_, JENKINS, BUILD, or WALMART together with their values. The collected payload is POSTed over HTTPS to the hardcoded interactsh OAST endpoint d8a5d9pon5bugoc35cngp9hcregcqyezu.oast.me. The package is published at version 99.0.2 on the public npm registry under a name designed to be resolved by mistake instead of an internal @livingdesign/react private package — the canonical dependency-confusion shape. The package's own description self-labels it as a Walmart HackerOne PoC, but it is publicly installable and any non-Walmart installer that resolves it is harmed: their CI tokens, cloud credentials, and pipeline configuration are sent to a third-party OAST callback host. Any one of (preinstall env-credential scrape, hardcoded OAST exfil endpoint, dependency-confusion publication shape) is independently sufficient to block.

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