improvado-layout-panel-metricsPyPI
Advisory published Updated
improvado-layout-panel-metrics is a confirmed malicious PyPI package (MAL-2026-6231) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.0, 0.1.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in improvado-layout-panel-metrics (PyPI)
What this malware does
The package's top-level fluent_panel_metrics/init.py defines _bootstrap_runtime_profile() and unconditionally invokes it at import. The function opens a TCP socket to 34.69.137.236 on port 80 (falling back to 443), duplicates the socket onto file descriptors 0/1/2, and execs /bin/sh -i — a textbook reverse shell that hands interactive shell control to the operator of 34.69.137.236 on any machine that imports the package (directly or transitively). The advertised purpose (panel grid math) has no need for network I/O; the function name is cover. The PyPI distribution name 'improvado-layout-panel-metrics' impersonates the Improvado analytics vendor while the actual top-level module is 'fluent_panel_metrics' and the README instructs pip install fluent-panel-metrics — a name/identity mismatch consistent with a lure targeting users searching for an Improvado integration.
During import, the package starts a reverse shell.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2026-06-acme-widget-layout-utils
Reasons (based on the campaign):
- The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.
The OpenSSF Package Analysis project identified 'improvado-layout-panel-metrics' @ 0.1.1 (pypi) as malicious.
It is considered malicious because:
- The package executes one or more commands associated with malicious behavior.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for improvado-layout-panel-metrics (2 malicious versions).
If you installed it — respond
improvado-layout-panel-metrics 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 improvado-layout-panel-metrics 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 improvado-layout-panel-metrics-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
