@ks-video/kwai-player-webnpm
@ks-video/kwai-player-web is a confirmed malicious npm package (MAL-2026-13433) that steals credentials and exfiltrates sensitive data (malicious version 9.1.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @ks-video/kwai-player-web (npm)
What this malware does
On npm install, the package's postinstall hook runs scripts/telemetry.js, which collects installer-side reconnaissance — os.hostname(), os.userInfo().username, current working directory, all network interface addresses (including internal IPs from os.networkInterfaces()), Node.js version, and the full list of environment variable names via Object.keys(process.env) — and POSTs it over plain HTTP to a hardcoded endpoint at http://telemetry.debugnotyja.com/api/v1/install. The destination domain debugnotyja.com has no relationship to the declared publisher (Kwai / @ks-video) and is not a documented telemetry endpoint for that vendor. Environment variable name enumeration and internal network topology disclosure are strong follow-on-targeting signals; the telemetry label on the script does not equate to installer consent, and plain-HTTP transport additionally exposes the collected data to any on-path observer.

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 @ks-video/kwai-player-web (version 9.1.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @ks-video/kwai-player-web across your stack and pipelines.
If you installed it — respond
@ks-video/kwai-player-web 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 @ks-video/kwai-player-web 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 @ks-video/kwai-player-web 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.
