svelte-map-visualnpm
Advisory published Updated
svelte-map-visual is a confirmed malicious npm package (MAL-2026-13678) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in svelte-map-visual (npm)
What this malware does
No malicious behavior was identified in this package version. No lifecycle scripts fetching or executing remote content, no credential or environment-variable scraping, no hardcoded exfiltration endpoints, and no silent-relay or backdoor mechanisms were observed in the shipped files.
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 svelte-map-visual (version 1.0.0).
If you installed it — respond
svelte-map-visual 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 svelte-map-visual 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 svelte-map-visual-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
