Cyber Warfare / Cyber Threats

The Iranian nation-state group MuddyWater has been implicated in conducting destructive operations on hybrid environments while masquerading as a ransomware campaign. According to new insights from the Microsoft Threat Intelligence team, these threat actors are targeting both on-premises and cloud infrastructures, often collaborating with a recently identified cluster known as DEV-1084. “Despite efforts to present their activities as a typical ransomware operation, the irreversible damage they inflict indicates that destruction and disruption were their primary objectives,” the company reported on Friday. MuddyWater is linked to Iran’s Ministry of Intelligence and Security (MOIS) and has been active at least since 2017, also recognized by various names in the cybersecurity field, including Boggy Serpens.

IoT Security / Zero Trust

The Shifting Landscape of Cybersecurity in Healthcare

In 2025, healthcare organizations are grappling with unparalleled cybersecurity threats. As operational technology (OT) environments come under increasing attack and the integration of IT and medical systems expands the potential for breaches, traditional security measures are falling short. Recent data reveals that the healthcare sector faced a record number of data breaches in 2024, compromising over 133 million patient records. The financial implications are severe, with the average cost of a healthcare data breach soaring to $11 million, making it the industry with the highest breach costs.

The tactics of cybercriminals have evolved significantly; they are now focused on compromising the very devices that provide patient care, rather than just stealing patient records. The risk has intensified, with ransomware accounting for 71% of attacks on healthcare organizations, resulting in an average operational downtime of 11 days per incident.
