Ghostwriter (UNC1151) has become one of the most closely tracked threat actors operating against Ukraine, NATO members, and Eastern European governments.
Over nearly a decade of activity, the group has combined credential harvesting, malware deployment, website compromises, cyber espionage, and coordinated influence operations targeting government institutions, military personnel, journalists, media organizations, and political actors. Public reporting has linked Ghostwriter to Belarusian military intelligence, while multiple government assessments and threat intelligence investigations have also pointed to coordination with Russian military structures and broader geopolitical objectives.
