robase-utilsPyPI
Advisory published Updated
robase-utils is a confirmed malicious PyPI package (MAL-2026-2558) that steals credentials and exfiltrates sensitive data (malicious version 2.3.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in robase-utils (PyPI)
What this malware does
During installation package downloads and runs a malicious executable. Likely continuation of 2026-03-rowrap.
The campaign is built over a malicious Roblox API wrapper. The roboat[.]pro (later robase[.]app) domain advertises a wrapper that is either directly malicious (as roboat collected in the campaign 2026-03-rowrap) or uses a malicious dependencies (like roboat-utils). New versions are published simultaneously with malicious dependencies and quickly removed. Another advertisement channel is https://github.com/Addi9000/roboat referencing two active contributors: https://github.com/Addi9000 and https://github.com/RoCruise
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

The package overrides the install command in setup.py to execute malicious code during installation.
-
Downloads and executes a remote executable.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for robase-utils (version 2.3.0).
If you installed it — respond
robase-utils 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 robase-utils 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 robase-utils-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
