Malicious package

react-dynamic-table-compenentnpm

react-dynamic-table-compenent is a confirmed malicious npm package (MAL-2026-6533) that typosquats a legitimate package to trick installs (malicious version 1.2.7). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall react-dynamic-table-compenent

What this malware does

Package name misspells 'component' as 'compenent', a one-letter typosquat of react-dynamic-table-component. The package's postinstall script runs node dist/setup.js, which fetches https://everydaynodechecker-39143n.vercel.app/api/key?mem=master and passes the response body directly to eval(), inside a function misleadingly named initDatabase. The fetched content is attacker-controlled and mutable, so any default npm install of this package executes whatever code the endpoint currently serves on the installer's machine. The cover-story naming (initDatabase, key?mem=master) presents the request as benign configuration while it is a remote code loader.

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

Typosquat

  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for react-dynamic-table-compenent (version 1.2.7). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging react-dynamic-table-compenent across your stack and pipelines.

  2. If you installed it — respond

    react-dynamic-table-compenent is a typosquat — you almost certainly intended a legitimately-named package. Remove react-dynamic-table-compenent, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

  3. Did it already run?

    If react-dynamic-table-compenent was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks react-dynamic-table-compenent before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
