elementary-dataPyPI
Advisory published Updated
elementary-data is a confirmed malicious PyPI package (MAL-2026-3083) that steals credentials and exfiltrates sensitive data (malicious version 0.23.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in elementary-data (PyPI)
What this malware does
Versions 0.23.3 were compromised.
A threat actor exploited a vulnerability in the CI workflows to inject code and establish, likely, a reverse shell in the CI environment (https://github.com/elementary-data/elementary/actions/runs/24914128534/job/72962412074). Following that, the access was used to create 3 PRs with malicious code, and finally publish the malicious 0.23.3 version of the elementary-data package to PyPI, which was available between 2026-04-24 22:20 and 2026-04-25 9:45 (UTC) (https://github.com/elementary-data/elementary/actions/runs/24914446630). Malicious code was also published as a Docker image.
Malicious code was inserted in a PTH file, causing execution on any Python run. It then collects all kinds of sensitive data (credentials, .env files, cloud tokens, cryptocurrency wallets, Kubernetes configurations, shell history, data from AWS secret manager, ...) and exfiltrates to the hardcoded target.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for elementary-data (version 0.23.3).
If you installed it — respond
elementary-data 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 elementary-data 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 elementary-data-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
