Perdas por ciberataques na área da saúde acima de 200.000 dólares quase quadruplicam em 12 meses, revela pesquisa da Netwrix

Netwrix, um provedor de cibersegurança focado em ameaças a dados e identidade, divulgou hoje novas descobertas do seu 2025 Cybersecurity Trends Report que revelam aumentos acentuados nas perdas relacionadas a ataques cibernéticos no setor de saúde.

The report found that nearly half (48%) of healthcare organizations experienced at least one cybersecurity incident over the past year. For many, the cost was severe: the share of healthcare respondents reporting losses above $200,000 nearly quadrupled from the previous year, rising from 5% in 2024 to 19% in this year’s survey. Losses above $500,000 also spiked, climbing from 2% reported losses last year to 12% this year. By comparison, across all industries in 2025, only 13% reported losses above $200,000 and 6% above $500,000.

Phishing, ransomware, and user account compromise were the most common attack types reported — threats that frequently begin with stolen credentials. Nearly one-third of respondents (31%) said their organizations had incidents involving compromised user or admin accounts.

The 2025 survey also asked about AI for the first time. More than a third of IT and security professionals (37%) said AI-driven threats had already forced them to strengthen defenses, showing how quickly adversaries are adopting AI to supercharge phishing and privileged account compromise. Even with greater investment in defenses, the findings suggest attackers — especially those using AI — are evolving faster than many defenders can adapt.

The healthcare findings are part of the Netwrix 2025 Cybersecurity Trends Report, based on a global survey of 2,150 IT and security professionals from 121 countries.
