robasePyPI
Advisory published Updated
robase is a confirmed malicious PyPI package (MAL-2026-2543) that steals credentials and exfiltrates sensitive data (malicious versions 2.1.0, 2.2.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in robase (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.

Reasons (based on the campaign):
-
The package overrides the install command in setup.py to execute malicious code during installation.
-
Downloads and executes a remote executable.
-
The malicious code is intentionally included in a dependency of the package

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