Which versions of datacamp-light are malicious?

The following PyPI versions of datacamp-light are flagged malicious: 99.0.0. Treat any of these as compromised.

How do I remediate datacamp-light if I installed it?

datacamp-light 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.

I already installed datacamp-light — how do I know if it already compromised me?

If datacamp-light 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.

Is datacamp-light part of a known attack campaign?

Yes — datacamp-light is associated with the GENERIC-standard-pypi-install-pentest, IN-MAL-2026-006751 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find datacamp-light across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for datacamp-light (version 99.0.0).

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

pip uninstall datacamp-light

What this malware does

datacamp-light 99.0.0 impersonates DataCamp's internal package (name='datacamp-light', author='DataCamp', url='https://github.com/datacamp/datacamp-light', anomalous version 99.0.0 — the canonical dependency-confusion bait shape). setup.py defines an exfiltrate() function and invokes it unconditionally at top level, so it fires during pip install. The function collects hostname, current working directory, platform, Python version, and USER/USERNAME environment variables, JSON-encodes them, and POSTs them via urllib.request.urlopen to https://z39gspa3.pingback.sh/c. Any installer whose resolver picks up this public artifact (the intent of the 99.0.0 version pin) leaks host and user identifiers to the pingback domain. Even though the package self-labels as a 'PoC,' the published artifact actively phones home from any machine that installs it.

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

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.

Detect & block this

O3 blocks datacamp-light-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
