Welcome to your daily cybersecurity podcast.A new initiative brings together volunteer cybersecurity experts to help protect water utilities against growing cyber threats. Experienced professionals from the DEF CON Franklin community are paired with water service providers across several U.S. states to conduct assessments, map operational technology (OT) environments, and implement security measures tailored to critical infrastructure constraints. This community-driven model aims to offset limited internal resources and improve resilience against targeted industrial cyberattacks.MongoDB has issued an urgent warning urging administrators to immediately patch a severe remote code execution vulnerability affecting components of its ecosystem. The flaw could allow unauthenticated attackers to execute arbitrary code on exposed Node.js servers. Proof-of-concept exploits are publicly available, significantly increasing the risk of real-world exploitation.Security researchers have uncovered a large-scale compromise campaign involving the PCPcat malware, which exploited critical flaws in Next.js and React server components. More than 59,000 servers were compromised within 48 hours, with attackers harvesting credentials, SSH keys, and environment variables while establishing persistent access using stealthy processes and tunnels.In France, La Poste and its banking subsidiary, La Banque Postale, suffered major service disruptions following a distributed denial-of-service (DDoS) attack during the holiday period. Several online services, including parcel tracking and digital banking, were rendered unavailable. Authorities stated that no customer data was compromised.Finally, security teams are monitoring increased risks linked to modern JavaScript server stacks, highlighting how the rapid adoption of frameworks such as React and Next.js has expanded the attack surface for automated, industrial-scale exploitation.Sources:Cyber Volunteers / Water Utility / MSSP : https://therecord.media/cyber-volunteer-water-utility-msspMongoDB – Severe RCE Patch Warning : https://www.bleepingcomputer.com/news/security/mongodb-warns-admins-to-patch-severe-rce-flaw-immediately/PCPcat – React/Next.js Servers Breach : https://thecyberexpress.com/pcpcat-react-servers-nextjs-breach/La Poste – Outage After a Cyber Attack : https://securityaffairs.com/186064/security/la-poste-outage-after-a-cyber-attack.htmlDon’t think, patch!Your feedback is welcome.Email: [email protected]: https://www.radiocsirt.comWeekly Newsletter: https://radiocsirtenglishedition.substack.com/
