A Snapshot of Cyber Tsunamis

When one organization is attacked, thousands can feel the impact.

A single cyber incident can trigger widespread disruption across interconnected organizations, creating financial and operational consequences far beyond the original victim.

New research from Mastercard Cybersecurity and the Cyentia Institute examines 100 of the largest multi-party cyber events over the past five years, revealing how ransomware, shared technology, and third-party dependencies amplify cyber risk.

Key Findings

14× Higher Financial Losses

Median losses from major multi-party cyber events are 14 times higher than those from single-party incidents.

62% Triggered by Ransomware

Ransomware is the leading catalyst for major cyber tsunamis, affecting 66% of downstream organizations.

77% of Losses from Disruptions

Operational disruptions generate the majority of financial losses despite occurring less frequently than data disclosures.

What You'll Learn

• How major cybersecurity incidents spread across third-party and digital supply chain relationships.
• Why ransomware remains the leading driver of large multi-party cyber events.
• How data disclosures and operational disruptions create different financial consequences.
• Which industries and organizations are most exposed to downstream cyber risk.
• Why continuous third-party cyber risk monitoring is essential to building resilience.
