@ziedzzz/demo-canarynpm
Advisory published Updated
@ziedzzz/demo-canary is a confirmed malicious npm package (MAL-2026-17652) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.0-stage, 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @ziedzzz/demo-canary (npm)
What this malware does
On npm install, the package's declared postinstall script executes index.js, which collects a host fingerprint (hostname, username, home directory, cwd, platform/arch/OS release, CPU model, memory, network interfaces including MAC/OUI, process info) and enumerates process.env for variable names matching TOKEN|SECRET|KEY|PASS|AWS_|GCP_|AZURE_|SSH|GIT|NPM|DOCKER. The collected data is transmitted via HTTPS GET to the hardcoded third-party endpoint telegrambot-aebk.onrender.com/ping. The behavior fires automatically on install without opt-in and discloses the installer's host identity and credential-variable inventory to an author-controlled destination.
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
Credential / info stealerFind it
Search your lockfiles and build artifacts for @ziedzzz/demo-canary (2 malicious versions).
If you installed it — respond
@ziedzzz/demo-canary 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 @ziedzzz/demo-canary 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 @ziedzzz/demo-canary-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
