Introduction
The SolarWinds cyberattack, publicly disclosed in December 2020, represents one of the most consequential software supply-chain compromises in modern history. By exploiting trusted update mechanisms within SolarWinds’ Orion network management platform, attackers gained covert access to thousands of organizations worldwide, including multiple United States federal agencies. The incident reshaped how governments and private-sector organizations assess supply-chain risk, vendor trust, and nation-state cyber threats. This case study examines the background, execution, impact, response, and strategic implications of the SolarWinds attack, highlighting lessons for future cyber conflict and defense.
