Cyber Briefing: 2026.08.11
Critical infrastructure providers, supply chain logistics networks, and enterprise platforms continue to be disrupted by active ransomware campaigns
Welcome to Cyber Briefing, your daily source for all things cybersecurity. We bring you the latest advisories, alerts, incidents, and news every weekday.
Active software vulnerabilities and ransomware schemes pose immediate operational risks to critical infrastructure and enterprise systems. Operations utilizing the Gunra ransomware strain are targeting key sectors by exploiting unpatched flaws in Fortinet and Schneider Electric systems. At the same time, a flaw in the Windows 11 Plug and Play service allows attackers to gain elevated SYSTEM-level permissions through emulated USB devices, creating remote privilege escalation pathways even on patched machines.
Enterprise security incidents and legal enforcement highlight both the risks of data exposure and broader shifts toward stronger verification controls. A breach at Ceva Logistics exposed sensitive customer and shipping information across multiple European operations, while workforce platform Deel moved to acquire identity verification firm Clarity to defend against AI-enabled fraud. Meanwhile, law enforcement achieved a major milestone with a 16-year federal prison sentence for Ransom Cartel operator Maksim Silnikau, as new open-source initiatives like Chainloop aim to enhance software supply chain integrity.

⚡THREAT LANDSCAPE
Gunra Ransomware Exploits Fortinet, Schneider
South Korean and U.S. cybersecurity agencies have issued a joint warning about Gunra ransomware attacks targeting critical infrastructure worldwide, including healthcare, financial services, government facilities, and nonprofit organizations. The ransomware variant exploits known vulnerabilities in Fortinet and Schneider Electric systems to gain initial access to victim networks. Organizations in affected sectors should immediately patch these vulnerabilities and review their security controls to prevent compromise. Read More
Windows 11 USB Plug and Play Privilege Escalation
Researchers discovered a privilege escalation vulnerability in Windows 11’s Plug and Play service that allows attackers to gain SYSTEM-level access by emulating USB devices and triggering automatic installation of signed vendor software. The attack can be executed remotely through Remote Desktop when USB redirection is enabled, affecting fully patched Windows 11 systems. Organizations should review Remote Desktop configurations and monitor for suspicious USB device activity until Microsoft releases a security update. Read More
🚨INCIDENTS & REAL-WORLD IMPACT
Ceva Logistics Data Breach Impacts European Clients
Ceva Logistics, a subsidiary of French shipping giant CMA CGM Group, suffered a data breach affecting eight European warehouses between July 29 and August 1, 2025. The incident exposed customer delivery information including names, email addresses, home addresses, phone numbers, and order details for clients such as gaming company Valve, Dutch retailer Bol, department store De Bijenkorf, football club Ajax, and bank ING. Security experts warn affected customers should expect targeted phishing attempts using stolen delivery information and advise verifying any delivery-related messages directly through official retailer websites rather than clicking links in emails.

💻 CAREER ENABLEMENT
Chainloop: Open-source supply chain security tool
Chainloop is an open-source tool that creates verifiable records of software build processes by capturing artifacts and generating signed attestations using the in-toto specification. The command-line tool integrates with CI/CD platforms like GitHub Actions, GitLab, Jenkins, and Dagger to automatically collect build outputs, store them in content-addressable storage, and document each step with cryptographic signatures. Security and compliance teams can use the control plane to verify the integrity and provenance of software artifacts throughout the supply chain. Read More
