basic-vitenpm
Advisory published Updated
basic-vite is a confirmed malicious npm package (MAL-2026-11131) 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 basic-vite (npm)
What this malware does
package.json declares preinstall: node index.js, so npm install basic-vite auto-executes index.js. The script collects host identity data (hostname, username, home directory, DNS servers, current working directory, package.json contents) and reads /etc/passwd and /etc/hosts, then POSTs the collected payload over HTTPS to the hardcoded Burp Collaborator subdomain md3wko7hlcmvfsq16xh2higublhc53ts.oastify.com. The package name suggests a Vite-related utility, but no such functionality is present; the sole behavior is install-time data exfiltration to an attacker-controlled out-of-band interaction host.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for basic-vite (version 1.0.0).
If you installed it — respond
basic-vite 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 basic-vite 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 basic-vite-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
