MAL-2026-5013
Summary: Malicious code in @mlspace/dtransfer (npm)
Details: Part of a dependency confusion attack campaign targeting the `@cloudplatform-single-spa` and `@mlspace` npm scopes. The attacker (npm user **mr.4nd3r50n**) published 139 scoped packages at the inflated version `99.99.99`, which resolves ahead of any private registry version via npm's default version resolution, silently hijacking installs of internal packages. On installation, the `postinstall` hook executes `scripts/postinstall.js`. The script waits 3 seconds (sandbox evasion), then downloads an OS-specific second-stage JavaScript payload from `https://oob.moika.tech/payload/{mac|win|linux}.js`, writes it to a temporary file (`._cloudplatform-single-spa_init.js` in the system temp directory), and spawns it as a detached Node.js process that continues running after npm exits. The payload exfiltrates the full `process.env` (environment variables including secrets, tokens, and credentials), along with hostname, username, platform, architecture, and working directory, to the C2 endpoint `https://oob.moika.tech/report`. If the second-stage download fails, a fallback beacon containing the same system details is sent to the same endpoint.
