Package attempts to collect environment variables from a specific environment, self-identified as BigQuery user-defined functions research. The final exfiltration of collected data seems to require the control of the execution environment, supporting the research/pentest claims.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.


Campaign: 2026-10-crelic-bqwheel-52f66a3f1d


Reasons (based on the campaign):


 - abuses-pth


 - exfiltration-env-variables


 - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
