This action undermined, or was intended to undermine, the integrity, prosperity and security of UK organisations and more broadly, the UK government, and directly or indirectly caused, or was intended to cause, economic loss to, or prejudice to the commercial interests of, those affected by the activity.

Official documents belonging to IfS were released in the hack and subsequent leak, resulting from the preparation of spear-phishing campaigns and associated activity. (Gender):Male
