Microsoft’s 2025 Digital Defense Report identifies the United States as one of four leading targets in its customer-impact data, alongside the United Kingdom, Israel, and Germany. That does not establish that the US is definitively the world’s most targeted country across all cyberattacks. Microsoft’s finding reflects malicious activity targeting its customers, not a census of every incident or a ranking shared by all security providers.

What Microsoft’s 2025 report says about the United States

Microsoft names the United States, United Kingdom, Israel, and Germany as leading targets in a country-impact view based on Microsoft Threat Intelligence. The report describes the measure this way: “This map pulls from data on how frequently customers are targeted by malicious activity in each country.” Microsoft’s 2025 Digital Defense Report covers July 2024 through June 2025.

The public summary does not give a US percentage or a complete ordinal ranking of every country. The finding supports saying the US is among Microsoft’s leading targets; it does not support an unqualified claim that it is number one worldwide.

What the ranking measures—and what it does not

Microsoft customer impact

The country view is based on how frequently Microsoft customers were targeted by malicious activity, with countries compared within their regions. It is a view of activity visible through Microsoft Threat Intelligence, not a count of every cyberattack against every person or organization.

Not a universal ranking or a nation-state count

The report’s customer-impact map is distinct from Microsoft’s observations of nation-state activity. A country’s position in the map should not be read as a count of government-sponsored operations, nor as proof that it has more attacks than every other country under every definition. The report presents Microsoft’s assessment; it does not establish a comparable cross-provider ranking using the same dates, population, and measure.

What the report says about attack motives and identity threats

In its 2025 report, Microsoft says attacks were largely financially motivated, espionage accounted for 4% of attacks, and password-spray activity made up 97% of observed identity attacks. These are Microsoft’s report-specific observations, not shares of all cyber incidents worldwide.

Do not confuse the 97% figure with a different statistic in Microsoft’s prior-year reporting. Microsoft said that over 99% of 600 million daily identity attacks were password-based and that 7,000 password attacks were blocked per second over the preceding year. Those figures describe a separate 2024 measurement and population; they are not another expression of the 2025 password-spray statistic. Microsoft’s 2024 Digital Defense Report provides that earlier context.

Sector figures provide context, not a US breakdown

Microsoft’s 2024 worldwide top-targeted-sectors chart lists IT at 24%, Education and Research at 21%, and Government at 12%. These are global sector shares in that report—not US-specific figures and not part of the 2025 country-impact ranking.

How to use the finding

The report is useful evidence that malicious activity targeting Microsoft customers affects the US prominently. It cannot establish a single definitive answer to “Which country is most targeted?” without a shared definition, population, period, and data source across countries and providers. Treat the country finding as Microsoft telemetry, rather than a measure of every attack occurring in the United States.

Practical ways to reduce account and organizational risk

For individuals: use phishing-resistant MFA where available

Microsoft recommends phishing-resistant multifactor authentication (MFA) and says it can block over 99% of identity-based attacks. That is Microsoft’s claim, not a guarantee for every account or deployment. Options can include a compatible FIDO2 hardware security key; check that the service and your device support the method, and set up recovery options so losing the key does not lock you out. No particular key or model is endorsed by the report. Microsoft’s October 16, 2025 report announcement gives its individual MFA recommendation.

For organizations: measure readiness, not just exposure

Microsoft’s organizational recommendations focus on resilience and measurable security practices. Useful measures include:

  • MFA coverage across accounts and systems.
  • Patch latency: how long systems remain unpatched after updates are available.
  • Incident-response time.
  • Potential access paths through trusted supply-chain partners and online services.
  • Resilience planning, including how operations will continue and recover after an incident.

These measures help organizations assess and improve defenses; they do not change what the country-impact map counts.
