Malicious code in po-ops-local-dev (npm)
What this malware does
[email protected] has no functional code of its own (index.js contains only module.exports = {}; and there are no lifecycle scripts). Its sole effect on install is to pull ltidisafe directly from https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.9.2.tgz — a Google Cloud Storage bucket, not the npm registry. The package name po-ops-local-dev combined with the depenconf path segment in the tarball URL is consistent with a dependency-confusion staging or research artifact. On npm install, npm fetches that tarball and runs any lifecycle scripts it contains; the contents at that GCS URL are mutable and outside npm's integrity verification. The actual installer impact depends entirely on what bytes the GCS bucket serves, which were not inspected here.
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.
The OpenSSF Package Analysis project identified 'po-ops-local-dev' @ 99.9.1 (npm) as malicious.
It is considered malicious because:

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for po-ops-local-dev (version 99.9.1).
If you installed it — respond
Remove po-ops-local-dev 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 po-ops-local-dev 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 po-ops-local-dev-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.
