clover-codelab-remote-pay-cloudnpm
Advisory published Updated
clover-codelab-remote-pay-cloud is a confirmed malicious npm package (MAL-2026-12353) that steals credentials and exfiltrates sensitive data (malicious version 99.9.9). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in clover-codelab-remote-pay-cloud (npm)
What this malware does
The package declares a postinstall hook that runs index.js on npm install. index.js collects the OS username, current working directory, hostname, and non-internal IPv4 address via os.userInfo(), process.cwd(), os.hostname(), and os.networkInterfaces(), then POSTs the values as JSON over https to a hardcoded webhook.site collector at https://webhook.site/9aa13631-fbb0-4b6b-a256-27d1672f767c. The package name resembles Clover's remote-pay-cloud SDK and the version is set to 99.9.9, a dependency-confusion shape intended to override an internal package during resolution. The package provides no functionality matching its name — its only install-time effect is the exfiltration beacon.

Credential / info stealerFind it
Search your lockfiles and build artifacts for clover-codelab-remote-pay-cloud (version 99.9.9).
If you installed it — respond
clover-codelab-remote-pay-cloud 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 clover-codelab-remote-pay-cloud 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 clover-codelab-remote-pay-cloud-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
