tailwind-animator-scrollnpm
tailwind-animator-scroll is a confirmed malicious npm package (MAL-2026-5618) that steals credentials and exfiltrates sensitive data (malicious version 1.7.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in tailwind-animator-scroll (npm)
What this malware does
The package's main entry src/index.js appends, after a large whitespace gap following the legitimate-looking Tailwind plugin code, an eval(atob('Z2xvYmFsWychJ109JzExJzt2YXIgXyRfMWU0Mj0...')) call. The decoded first stage re-exposes Node's require and module as global aliases (global['c']=require, etc. — typo-style obfuscation) and then invokes a second-stage IIFE that uses a custom shuffle decoder plus the Function() constructor to assemble and execute a further opaque payload. Because this lives in the main entry, simply adding the plugin to tailwind.config.js executes attacker-controlled code inside the developer's build environment, where CI tokens, environment variables, source code, and credentials are all reachable. The package additionally impersonates the legitimate tailwindcss-animationfound plugin: the README copies its CSS class names and API surface verbatim, the install snippet uses yet another misspelling (tailwind-animatior-scroll), and a shields.io badge links to the real tailwindcss-animationfound package — a typosquat lure designed to catch developers who mistype or fuzzy-search for the legitimate plugin.
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
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for tailwind-animator-scroll (version 1.7.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging tailwind-animator-scroll across your stack and pipelines.
If you installed it — respond
tailwind-animator-scroll 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 tailwind-animator-scroll 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.
How O3 protects you
O3 blocks tailwind-animator-scroll 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.
