Upon discovery, all identified websites and domains were added to Safe Browsing to protect users from further exploitation. We also send all targeted Gmail and Workspace users government-backed attacker alerts notifying them of the activity. We encourage any potential targets to enable Google Account Level Enhanced Safe Browsing and ensure that all devices are updated.
