Summary
Malicious code in robase-ui (PyPI)
Details

Source: kam193 (9ca93a110c410fd6294e5270289bebb1872f9b81152d837f4990756881646cc0)

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.

Campaign: 2026-03-roboat-addition

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

  • malware

  • clones-real-package
