According to a new report by Microsoft, ransomware attacks on the healthcare sector are rising and putting lives at risk.  The researchers, during their study, found that there has been a 300% increase in ransomware attacks on the healthcare sector since 2015, and there has been an increase in stroke and cardiac arrest cases at hospitals receiving patients from nearby facilities paralyzed by such attacks. Microsoft noted that healthcare is one of the top 10 most targeted sectors, and the average payment from a survey of healthcare organizations was $4.4 million.

According to a new study by researchers at Fortinet, nearly 70% of business leaders believe their employees lack critical cybersecurity knowledge, a sharp increase from 56% in 2023.  The researchers also found that AI-driven cyberattacks are becoming more difficult for employees to detect.  Over 60% of survey respondents expect a rise in employees falling victim to AI-enhanced attacks. However, 80% of those surveyed said that increased awareness of these AI-augmented threats has prompted organizations to embrace security awareness and training programs.

The United States Department of Justice and the cybersecurity agency CISA have started seeking comments on a proposed rule for protecting the personal data of Americans against foreign adversaries.  The goal is to prevent data brokers, which are companies that collect and aggregate information and then sell it or share it, from providing bulk data collected on American citizens, as well as government-related data, to countries of concern, such as China, Cuba, Iran, North Korea, Russia, or Venezuela.

Researchers at SentinelOne have observed a new macOS malware family dubbed "NotLockBit" that poses as "LockBit" ransomware. NotLockBit, which is written in the Go programming language, targets both Windows and macOS systems. According to SentinelOne, the malware is distributed as an x86_64 binary, suggesting that it only works on Intel and Apple silicon macOS devices running the Rosetta emulation software. This article continues to discuss findings regarding the NotLockBit ransomware.

The Sysdig Threat Research Team (TRT) has reported that cloud-based cyberattacks increased significantly in 2024 as threat actors used new methods to exploit cloud resources. In addition to LLMjacking, which targeted Large Language Models (LLMs), attackers weaponized open source tools and increased automation in 2024, causing financial damage and expanding the attack surface for cloud-hosted enterprises. This article continues to discuss the rise in the performance and abuse of LLMjacking and open source tools in cloud attacks.

The "Alphv/BlackCat" ransomware gang appears to have resurfaced as "Cicada3301," which is written in the Rust programming language. It has many similarities to BlackCat, claiming over 30 victims since June 2024, primarily in the healthcare, hospitality, manufacturing/industrial, and retail industries of North America and the UK. This article continues to discuss findings regarding the Cicada3301 ransomware.

Researchers at Iowa State University are building zero-trust cybersecurity tools to protect power grids that include renewable resources such as wind or solar farms. The research project, supported by the US Department of Energy's (DOE) Office of Cybersecurity, Energy Security, and Emergency Response (CESER), will develop zero-trust-based cybersecurity algorithms and tools to reduce cyber exposure. The developed solutions will also improve real-time situational awareness and mitigate attacks on grids integrated with renewable energy sources.

Germany's CERT@VDE has notified organizations of several critical and high-severity vulnerabilities found in industrial routers. One of the vulnerable devices is the MB Connect Line's mbNET.mini router, which is used worldwide as a Virtual Private Network (VPN) gateway for remote access and maintenance of industrial environments. This article continues to discuss the potential exploitation and impact of the vulnerabilities found in mbNET.mini and Helmholz industrial routers.

Researchers at the University of Pennsylvania's School of Engineering and Applied Science (Penn Engineering) discovered that certain features of Artificial Intelligence (AI)-governed robots have previously unidentified security vulnerabilities. The research, funded by the National Science Foundation (NSF) and the Army Research Laboratory (ARL), seeks to address the emerging vulnerability to ensure the safe deployment of Large Language Models (LLMs) in robotics.

According to ETH Zurich researchers Jonas Hofmann and Kien Tuong Turong, multiple End-to-End Encrypted (E2EE) cloud storage platforms have security vulnerabilities that could expose user data to malicious actors. The researchers revealed issues with Sync, pCloud, Icedrive, Seafile, and Tresorit, which over 22 million people collectively use. They found severe vulnerabilities in all five products, including implementations that enable malicious actors to inject files, tamper with data, or access user files.
