Critical RCE Vulnerability (CVE-2025-11953) in React Native NPM Package Puts Developers at Risk

A critical remote code execution (RCE) vulnerability, CVE-2025-11953, has been discovered in a popular React Native command-line tool, putting millions of developers at risk. The flaw, rated 9.8 on the CVSS scale, exists in the '@react-native-community/cli' NPM package and allows an unauthenticated attacker to execute arbitrary code on a developer's machine by sending a malicious request to the Metro development server. This could lead to source code theft, malware injection, or a full-blown supply chain attack. Meta has released a patch, and developers are strongly urged to update their dependencies.

Conti's Ghost: New 'DragonForce' Ransomware Adopts Cartel Model

HIGH

DragonForce Ransomware Emerges, Using Leaked Conti Code and a 'Cartel-Style' Affiliate Model

A new ransomware operation named DragonForce has been identified by security researchers, notable for its use of leaked source code from the infamous Conti ransomware. Instead of a traditional Ransomware-as-a-Service (RaaS) model, DragonForce operates with a 'cartel-like' structure, providing affiliates with a builder to create their own branded ransomware variants. This approach facilitates the rapid proliferation of new threats, with groups like 'Devman' already seen deploying malware created with the DragonForce builder. The core malware retains Conti's technical features, including its encryption scheme and ability to spread via SMB.

EU Conducts 'BlueOLEx 2025' Exercise to Test Joint Response to Major Cyber Crises

The European Union has concluded its 2025 'Blueprint Operational Level Exercise' (BlueOLEx), a large-scale simulation designed to test and improve the bloc's collective response to major cybersecurity crises. Hosted in Cyprus with support from the EU's cybersecurity agency, ENISA, the exercise brought together senior officials from all member states to role-play a significant cyber incident affecting critical sectors. The drill was the first to test the new EU Cyber Blueprint, which aims to clarify roles and streamline coordination between national authorities and the European Commission during a cross-border attack.

US Cyber Threat Sharing Law 'CISA 2015' Expires, Creating Potential Intelligence Gap

MEDIUM

Cybersecurity Information Sharing Act of 2015 Sunsets, Sparking Industry Fears of Reduced Public-Private Collaboration

Update:

The U.S. House Committee on Homeland Security's 'Cyber Threat Snapshot' warns that national cyber defenses are severely hampered by the ongoing federal government shutdown and the continued lapse of CISA 2015. This dual crisis creates 'dangerous blind spots' amidst escalating threats from nation-state actors like China and Iran, with a 133% spike in Iranian attacks and a rise in AI-driven cyberattacks. The report emphasizes reduced situational awareness and increased risk to critical infrastructure, urging immediate action to restore funding and information-sharing legislation.
