Malicious code in cloud-pc-templates (npm)
What this malware does
The ai login CLI subcommands (loginMode huggingface, ollamacloud, ollamalocal) each download a proxy script from a mutable refs/heads/main branch of a personal GitHub repository (raw.githubusercontent.com/devashish234073/cloud-pc-templates-marketplace/refs/heads/main/JS-PROXIES/{hf-proxy.js,ollama-proxy.js,ollamaoffline-proxy.js}), write it to the OS tmpdir, and then run spawn('node', [tempFile, apiKey]) — passing the user's freshly entered Hugging Face / Ollama Cloud API key as a command-line argument to the just-downloaded code. There is no commit pin, no tag, no checksum, and no signature verification. Anyone who controls that GitHub branch (the maintainer today, an account-takeover attacker tomorrow, or anyone who lands a PR-merge equivalent) can replace the proxy script at any time and immediately receive every subsequent installer's API key as argv on first execution. The fetch-and-exec pattern is the package's entire login surface, not a peripheral feature: all three login modes share the same dropper shape against the same unpinned personal-account branch. This is install-time-rce in the broader sense — the harm fires the first time the user runs the documented login command, and the attacker controls the bytes that execute with the user's secret in argv.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for cloud-pc-templates (version 1.3.0).
If you installed it — respond
Remove cloud-pc-templates from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If cloud-pc-templates 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 cloud-pc-templates-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
