Healthcare & Cybersecurity: The HEAL Security Dispatch on Ransomware, Data Breaches, and Critical Vulnerabilities

Welcome to the HEAL Security Dispatch Daily Digest, the leading podcast for the latest in cybersecurity trends and insights, brought to you by HEAL Security. I'm your host, Richard Simmons, broadcasting from London with a special focus on the intersection of healthcare and cybersecurity intelligence. In today's episode, we delve into a significant security breach at AT&T, where unauthorized access has compromised the call and text records of nearly all its customers, highlighting escalating privacy concerns. We also discuss the emergence of Ransomcortex, a new ransomware group specifically targeting healthcare facilities for financial extortion, and not operating under the Ransomware as a Service (RaaS) model, marking a dangerous evolution in cybercriminal tactics. Additionally, we cover a recent ransomware attack on the pharmacy chain Rite Aid, potentially exposing customer data and underscoring the persistent threat of cyber attacks on businesses. The episode further explores issued warnings by the Cybersecurity and Infrastructure Security Agency (CISA) and the FBI regarding critical vulnerabilities that could allow attackers to commandeer systems. Moreover, we investigate a DNS hijack impacting cryptocurrency platforms on Squarespace, and a cyber incident in Florida disrupting the issuance of new birth certificates, presenting a real-world implication of cybersecurity lapses on public services. Lastly, we navigate through the hidden cyber risks associated with mergers and acquisitions in the healthcare sector, emphasizing the need for stringent cybersecurity and technology assessments.
