dash-grid-normalizerPyPI
Advisory published Updated
dash-grid-normalizer is a confirmed malicious PyPI package (MAL-2026-5725) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.1, 0.0.2, 0.0.3…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dash-grid-normalizer (PyPI)
What this malware does
On import, src/dash_grid_normalizer/init.py calls _hydrate_remote_layout_profile(), which reassembles a payload from four string segments, base64-decodes and zlib-decompresses it, and passes the result to builtins.exec(). The decoded Python source imports os/socket/subprocess, connects a TCP socket to 43.69.137.236:80, dup2's stdin/stdout/stderr onto the socket, and execs /bin/sh — a standard reverse shell granting the operator of that IP interactive command execution as the installer's user. The C2 IP literal is itself further obfuscated as bytes([52,51,46,...]). The package's pyproject description ("Responsive grid and gutter helpers for dashboard widget layouts") and name are cover; the README self-identifies the project as a pentest probe with the reverse shell "LIVE CONFIRMED". Any process that does import dash_grid_normalizer (including transitive imports during test or build) opens the shell.
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for dash-grid-normalizer (5 malicious versions).
If you installed it — respond
dash-grid-normalizer 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 dash-grid-normalizer 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 dash-grid-normalizer-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
