chart-animation-helpernpm
chart-animation-helper is a confirmed malicious npm package (MAL-2026-10781) 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 chart-animation-helper (npm)
What this malware does
Package is published as 'chart-animation-helper' and described as 'Lightweight chart animation utilities', but the module contains no chart or animation functionality. The sole content is a self-labeled XSS proof-of-concept payload aimed at ai.zoom.us via CDN nonce injection: it injects a red banner into a DOM element with id 'root' and calls window.widgetSend with an 'xss_poc' message. The code has no npm lifecycle hooks, no Node network I/O, and no filesystem access; it depends on document/window APIs and is inert in a Node context. Installing or requiring the package does not exfiltrate data, execute remote code, or persist on the installer's machine. The concern is (1) deceptive package metadata (name and description do not match shipped code) and (2) shipping an attack payload targeting a third-party origin under a benign-sounding name, which is not a supply-chain attack on the installer but warrants human review for potential registry-policy action.
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 chart-animation-helper (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging chart-animation-helper across your stack and pipelines.
If you installed it — respond
chart-animation-helper 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 chart-animation-helper 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 chart-animation-helper 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.
