Vwork: Weaponized Open-source Software as an Addon for Gigabud

    Date: 09/10/2026

    Severity: Medium

    Summary

    GoldFactory has weaponized Vwork, a modified version of the open-source Android cloning app Shelter, as an add-on to the Gigabud Android banking trojan. Vwork uses the Android Work Profile to clone banking applications into an isolated space, helping hide Gigabud from security detection while maintaining remote control of victims’ devices. The Gigabud–Vwork infection chain was confirmed in Indonesia, with activity targeting users across Asia, the Middle East, Africa, and Latin America.
