About 75% of healthcare sector entities that suffered a ransomware attack over the past year were targeted on a weekend or holiday, highlighting the need for organizations to bolster staffing and related strategies during these vulnerable times, said Jeff Wichman of security firm Semperis.

The torrents of public hostility directed at health insurers in the aftermath of UnitedHealthCare CEO Brian Thompson's murder are serious signs of intensifying cyber and physical threats facing the C-suites of healthcare and many other sectors, said Chris Pierson, founder and CEO of BlackCloak.

Hackers can potentially use AI to manipulate data that's generated and shared by some health apps, diminishing the data's accuracy and integrity, said Sina Yazdanmehr and Lucian Ciobotaru of cybersecurity firm Aplite, describing a recent research project involving Google Health Connect.

Third-party access management poses significant cybersecurity risks in healthcare, but continuous identity management and monitoring can help mitigate those risks, said Jim Routh, chief trust officer at Saviynt.

Thousands of unique IP addresses are potentially exposing medical devices, electronic medical records systems and other sensitive healthcare information to the internet, said security researcher Himaja Motheram of security firm Censys, which made the discovery.

It goes without saying: Business ecosystems are increasingly complex, and so are the cybersecurity systems and strategies deployed to protect them. But Marty McDonald of Optiv and Rob Rachwald of Palo Alto Networks share new ideas on how to take some of the complexity out of cybersecurity.

When a large hospital in an urban area is shut down by ransomware, the disruption can be significant, but when a rural hospital faces a similar cyber outage, the impact on patient safety and the community can be extreme, said Nitin Natarajan of the Cybersecurity and Infrastructure Security Agency.

While ransomware attacks against medical devices don't happen often, disruptive cyber incidents that affect the availability of the IT systems that medical devices rely on are a big concern that needs the industry's critical attention, said Jessica Wilkerson of the FDA.

It's crucial for healthcare sector organizations to vet their artificial intelligence tech vendors in the same robust way they scrutinize the privacy and security practices of all their other third-party suppliers, said attorney Linda Malek of the law firm Crowell & Moring.

Healthcare organizations should rethink some of their approach to security, enhancing focus on insider threats, improving cyber awareness training and securing mobile applications and devices, said Ryan Witt, vice president of industry solutions at Proofpoint, discussing findings of a new study.
