Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for ajenti-plugin-testing-pyld (3 malicious versions).
If you installed it — respond
Remove ajenti-plugin-testing-pyld 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 ajenti-plugin-testing-pyld 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 ajenti-plugin-testing-pyld-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.
