Threat Actor RedCurl Develops Ransomware to Encrypt Hyper-V Servers #RedCurl, a threat actor active since 2018 and known for stealthy corporate #espionage, has begun deploying #ransomware in addition to its traditional data exfiltration methods. Researchers recently observed RedCurl using a ransomware variant called #QWCrypt, designed to target virtual machines hosted on #Microsoft Hyper-V. RedCurl’s pivot to ransomware is yet another example of the growing convergence between #cybercriminal and nation-state operations—a trend we’ve been warning about for years... https://lnkd.in/dDR-bfPU #cyberattack #infosec #security #cybersecurity

Ransomware is coming for critical infrastructure. Are you ready? 67% of energy, oil, gas, and utility operations were hit by ransomware in 2024. Nearly all of them reported attempts to compromise their backups. Energy providers operate in a high-stakes environment where downtime means millions in lost revenue, disruptions to essential services, and cascading failures across entire economies. Threat actors exploit this pressure. They use ransomware to halt operations, steal sensitive data, and force urgent ransom demands. Here’s what is happening: -Ransomware groups target energy grids and utilities because they are critical, high-value systems. -Attackers aim to disable backups, cutting off the ability to restore operations quickly. -The pressure to pay increases when critical systems are offline and recovery options are limited. Halcyon neutralizes these attacks before they take control: -Detects and stops ransomware before encryption begins. -Blocks data exfiltration attempts, preventing extortion. -Captures encryption keys, allowing for fast recovery without ransom payments. Energy companies need proactive defense. Attackers constantly refine their tactics. Security must evolve to match them. Learn how Halcyon protects the energy sector.

Cross-Platform #VanHelsing Ransomware Targets Windows, Linux and VMware ESXi Researchers have identified a new ransomware-as-a-service (RaaS) group called VanHelsing, which launched on March 7 and has already targeted three organizations, demanding $500,000 from each. Despite its cross-platform design supporting Windows, Linux, VMware ESXi, BSD, and Arm-based systems, only Windows machines have been infected so far. Researchers believe VanHelsing is an original ransomware strain, not a rebrand While #ransomware groups are increasingly developing #Linux variants, most attacks remain concentrated on #Windows environments—for now. https://lnkd.in/gqZQgT_z #cybersecurity #infosec #security #cyberattack
