hello-dynamicPyPI
Advisory published Updated
hello-dynamic is a confirmed malicious PyPI package (MAL-2026-5518) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.0, 0.1.1, 0.1.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in hello-dynamic (PyPI)
What this malware does
hello-dynamic 0.1.2 is a near-empty package whose init.py only defines a hello() function printing 'Hello!'. Its setup.cfg declares a dependency_links entry pointing at a webhook.site UUID endpoint (https://webhook.site/56557fe9-5bcf-4f26-bed7-38f772525011/pypi/aliga-raison). webhook.site is a generic HTTP-callback inspector commonly used to receive beacon traffic. Modern pip ignores dependency_links, so installer harm is minimal in practice, but the artifact's shape — trivial code, no real functionality, install metadata pointing at a request-inspector endpoint named after a PyPI package — is consistent with a reconnaissance probe testing which installers still process dependency_links. No exfiltration, RCE, credential read, or persistence mechanism is present in the package code.
Package attempts to test exploitation via legacy dependency_links configuration
Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.
Campaign: GENERIC-standard-pypi-install-pentest
Reasons (based on the campaign):
-
The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
-
The package overrides the install command in setup.py to execute malicious code during installation.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for hello-dynamic (3 malicious versions).
If you installed it — respond
hello-dynamic 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 hello-dynamic 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 hello-dynamic-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
