Chaos malware expands from routers to Linux cloud servers

Chaos, Go-based malware first documented by Lumen’s Black Lotus Labs, has historically targeted routers and edge devices. A new variant observed in March 2026 shows the malware operating against misconfigured Linux cloud servers, a category of infrastructure the botnet had not previously prioritized. Darktrace’s malware research team documented the compromise through its CloudyPots program, a global honeypot network the company runs to capture attacker behavior across a range of services and cloud platforms. One honeypot … More → The post Chaos malware expands from routers to Linux cloud servers appeared first on Help Net Security.

Flatpak 1.16.4 fixes sandbox escape and three other security flaws

Flatpak, a Linux application sandboxing and distribution framework, released version 1.16.4, patching four security vulnerabilities. The most severe fix addresses a complete sandbox escape that leads to host file access and code execution in the host context, tracked as CVE-2026-34078. File system exposure Two additional fixes address file system exposure on the host. CVE-2026-34079 prevents arbitrary file deletion on the host filesystem. GHSA-2fxp-43j9-pwvc prevents arbitrary read-access to files in the system-helper context. The fourth fix, … More → The post Flatpak 1.16.4 fixes sandbox escape and three other security flaws appeared first on Help Net Security.

Secureframe expands Comply with User Access Reviews for automated governance

Secureframe has announced the launch of User Access Reviews, a new capability within Secureframe Comply. Access reviews are the primary mechanism organizations use to validate that the right people have the appropriate access, but the process has historically been manual, fragmented, and difficult to audit. Most teams still conduct access reviews using exported spreadsheets and email threads, creating accountability gaps and leaving security incidents waiting to happen. User Access Reviews eliminates that risk. The new … More → The post Secureframe expands Comply with User Access Reviews for automated governance appeared first on Help Net Security.

What managing partners should ask AI vendors before signing any contract

In this Help Net Security interview, Kumar Ravi is the Chief Security & Resilience Officer at TMF Group, argues that over-privileged access and weak workflow controls pose more danger than ransomware attacks, precisely because they accumulate quietly and go unnoticed. He addresses the tension between legal privilege and timely threat-sharing, the challenge of managing fourth-party vendor risk, and the questions firms should ask before adopting AI-native tools. His broader argument: security needs to sit at … More → The post What managing partners should ask AI vendors before signing any contract appeared first on Help Net Security.

6G network design puts AI at the center of spectrum, routing, and fault management

Wireless network operators are preparing for a generation of infrastructure where AI is built into the architecture from the start. Sixth-generation networks, expected to reach commercial development over the coming decade, are being designed with AI at the center of how spectrum is allocated, traffic is routed, and failures are detected. A paper by researchers at Harokopio University of Athens examines how different AI techniques map to specific layers of 6G network design, from the … More → The post 6G network design puts AI at the center of spectrum, routing, and fault management appeared first on Help Net Security.

Cybercriminals move deeper into networks, hiding in edge infrastructure

Attack activity is moving toward infrastructure outside endpoint visibility. Proxy networks support a wide range of operations, edge devices serve as initial access points, and GenAI speeds up how attackers assemble and rebuild their tooling. Lumen’s 2026 Threatscape Report describes this pattern in criminal and nation-state activity. “Threat intelligence is needed to find the adversary as early as possible and as close to the point of origination as possible,” said Chris Kissel, IDC VP, Security … More → The post Cybercriminals move deeper into networks, hiding in edge infrastructure appeared first on Help Net Security.
