A ransomware attack targeted a major Irish hospital under the **Health Service Executive (HSE)**, encrypting critical patient systems and stealing sensitive medical records, including personally identifiable information (PII) of thousands of patients. The attack disrupted emergency services, delayed surgeries, and forced the hospital to divert ambulances to other facilities for over 48 hours. Cybercriminals demanded a multi-million-euro ransom, threatening to leak patient data on the dark web if unpaid. The hospital’s outdated legacy systems and lack of phishing-resistant MFA (noted in the article as a 97% vector for identity attacks) were exploited. While the HSE refused to pay, the incident triggered a nationwide audit of healthcare cybersecurity, revealing systemic vulnerabilities in Ireland’s public health infrastructure. The attack aligns with the article’s trend of ransomware actors targeting critical services with life-or-death stakes, leveraging AI-enhanced phishing and stolen credentials from infostealer malware like **Lumma Stealer** (disrupted by Microsoft in May 2025).

'description': "In the first half of 2025, Microsoft's data revealed that "
'over 52% of cyberattacks were driven by extortion or '
'ransomware, with financial gain as the primary motivation '
'(52% vs. 4% for espionage). Ireland ranked 46th globally and '
'20th in Europe for cyberactivity impact (~1.2% of affected '
'customers). Key trends included: (1) **Critical '
'infrastructure targeting**: Hospitals, local governments, and '
'SMEs faced heightened attacks due to weak defenses, leading '
'to real-world disruptions (e.g., delayed medical care, '
'canceled classes). (2) **Nation-state expansion**: China, '
'Iran, Russia, and North Korea escalated espionage and '
'financially motivated attacks, with Russia increasing '
'NATO-targeted cyberactivity by 25% YoY. (3) **AI adoption**: '
'Attackers used AI to automate phishing, scale social '
'engineering, and develop adaptive malware, while defenders '
'leveraged AI for threat detection (e.g., Microsoft blocks '
'4.5M daily malware attempts). (4) **Identity-based attacks**: '
'97% of identity attacks were password-related, with a 32% '
'surge in H1 2025, fueled by credential leaks and infostealer '
'malware (e.g., Lumma Stealer, disrupted in May 2025). (5) '
'**Workforce vulnerabilities**: 30% of Irish workers received '
'no cybersecurity training in 2025, with SMEs (19% trained) '
'and older employees (58% for 55–64 vs. 71% for 25–34) at '
'higher risk. Microsoft emphasized modern defenses (AI, '
'phishing-resistant MFA) and cross-sector collaboration as '
