web3dummyctiPyPI
Advisory published Updated

Malicious code in web3dummycti (PyPI)
What this malware does
If the method from the module is called, it attempts to download a malicious code (identified as msf payload) and save it locally. In the analysed version, the code starting the malicious code was commented out.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for web3dummycti (version 0.1.0).
If you installed it — respond
web3dummycti is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If web3dummycti 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 web3dummycti-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
