🛡️ MAL-2026-5025 — profile

Malicious code in @mlspace/profile (npm)

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.
