Christopher Krebs, the former head of the Cybersecurity and Infrastructure Security Agency (CISA), has left his position at cybersecurity firm SentinelOne. His departure follows an executive order from former President Trump aimed at strengthening national infrastructure security. Krebs was notable for his role in safeguarding the 2020 election from foreign interference and was dismissed for his views on election security. His leadership at CISA emphasized collaboration between public and private sectors to combat cyber threats. Krebs's exit raises concerns about how political developments may affect cybersecurity leadership and strategy within the private sector.

The National Council of State Boards of Nursing (NCSBN) has published its 2024 National Nursing Workforce Study, revealing that over 138,000 nurses have left the workforce since 2022. The study, based on a survey of around 800,000 nurses, points to persistent labor shortages and systemic issues within the nursing profession, although there is a slight improvement in employment levels. High stress and burnout remain significant concerns, with nearly 40% of nurses expressing intentions to exit the profession by 2029. Key findings show that 9% of registered nurses and over 41% of licensed practical/vocational nurses plan to retire or leave their jobs in the next five years, citing similar reasons as in previous years. Median annual earnings for both groups have increased by 10-16%, likely due to inflation and heightened healthcare needs.

The Cybersecurity and Infrastructure Security Agency (CISA) has released guidance amid concerns of unauthorized access to a legacy Oracle cloud environment, primarily highlighting the dangers of compromised credentials. While the extent of the breach is not fully determined, the situation poses significant risks as exposed or reused credentials can lead to unauthorized access across systems. CISA warns that attackers can exploit harvested credentials for escalating privileges, accessing sensitive systems, and launching phishing campaigns. To counter these threats, organizations are advised to reset passwords for affected users, examine code for hardcoded credentials, monitor authentication logs for anomalies, and implement phishing-resistant multi-factor authentication (MFA). CISA also encourages organizations to refer to their cybersecurity resources for further best practices.

A study published in PLOS One by Northwestern Medicine highlights the potential of using electronic health record (EHR) data to identify individuals at risk of homelessness by tracking changes in their residential addresses. The research, led by Abel Kho, MD, analyzed data from about one million patients and found that those with a history of homelessness experienced significantly more address changes compared to those without. The increasing homelessness rates in the U.S. underscore the need for healthcare institutions to leverage EHR data effectively to address housing instability, which can adversely affect health outcomes and incur higher healthcare costs.
