How do I remediate oa-crm-webapi if I installed it?

Remove oa-crm-webapi 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 network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

What this malware does

[email protected] is a dependency-confusion payload squatting an internal-sounding package name. package.json declares a postinstall hook (node beacon.js) which fires automatically on npm install. beacon.js reads os.hostname() and transmits it to the attacker-controlled Burp Collaborator host yfhjhookbia8zov0q5hh772xroxfl69v.oastify.com via two channels: a DNS lookup of <nonce>.<hostname>.<collaborator-host> (out-of-band DNS exfil) and an HTTPS POST to the same host with the hostname in the body. The 9.9.99 version + generic 'internal placeholder' description is the canonical shape used to hijack private package names by overriding the legitimate internal registry resolution. A successful install both proves code execution on the installer and leaks the internal hostname to an external attacker.
