time-server-analysisPyPI
Advisory published Updated
time-server-analysis is a confirmed malicious PyPI package (MAL-2025-191902) that steals credentials and exfiltrates sensitive data (malicious version 0.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in time-server-analysis (PyPI)
What this malware does
This campaign is built from two parts:
- packages named like time-check-server, snapshot-photo contain an innocent-looking code that sends "date" to a remote server,
- packages named like alicloud-client are clones of legit aliyun-python-sdk-core package, with a small change in the client.py code, where it imports the time-check-server and calls it, but instead of a date, the credentials to the cloud are exfiltrated. There are also variations with AWS clients
Apparently, the campaign started at least 2 years ago with the snapshot-photo package containing the same functionality as the newer time-check-server (see https://github.com/pypi-data/pypi-mirror-238/blob/code/packages/snapshot-photo/snapshot_photo-0.0.3-py3-none-any.whl/snapshot_photo/date_format.py).

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for time-server-analysis (version 0.0.1).
If you installed it — respond
time-server-analysis 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 time-server-analysis 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 time-server-analysis-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
