MAL-2026-10416 Malicious code in kuaishou (npm)

The package's prepare lifecycle script, which runs automatically on npm install, collects host, user, and platform identifiers along with the full process.env and POSTs them to a hardcoded ngrok tunnel at crabbing-thong-overhung.ngrok-free.dev (path /?cross_os_cloud=1). When executed in GitHub Actions, it additionally reads ACTIONS_ID_TOKEN_REQUEST_URL and ACTIONS_ID_TOKEN_REQUEST_TOKEN, requests a GitHub Actions OIDC ID token, and includes that token in the exfiltrated payload. The version number (99.9.9) and hardcoded attacker-controlled tunnel destination are consistent with a dependency-confusion / typosquat lure targeting CI environments; the OIDC token can be exchanged for cloud credentials via configured trust relationships.

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.
