BGP Role model: tracking the adoption of RFC 9234
Route leaks push traffic down paths it was never meant to take. We have written and spoken publicly in the past about route leaks in Border Gateway Protocol (BGP), depicting these events as impactful incidents that cause misdirection of traffic through unintended network paths. BGP routing is driven by the relationships between Autonomous Systems (ASes), i.e., customer-provider and peer-peer.
How to Install NAKIVO Backup & Replication on Linux
This guide shows you how to install the full NAKIVO solution — director, transporter and a default backup repository — on a Linux server in console mode. You'll also see which requirements to check before you start, and how silent installation lets you deploy NAKIVO automatically instead of running each step by hand.
Convert Physical Linux to Hyper-V VM Using Backup | Step-by-Step P2V Guide
Learn how to convert a physical Linux machine to a Hyper-V virtual machine using a backup with NAKIVO Backup & Replication. In this step-by-step tutorial, you will see how to back up an Ubuntu Linux physical server and export the backup as a Hyper-V VHDX virtual disk, allowing you to quickly perform physical-to-virtual (P2V) migration and restore workloads to a virtual environment. This method is useful for.
How to Convert a Physical Linux Machine to VMware ESXi (P2V) - Two Proven Methods
Learn how to convert a physical Linux machine to a VMware ESXi virtual machine using two proven physical-to-virtual (P2V) migration methods. In this step-by-step tutorial, you will see how to migrate an Ubuntu 24.04 LTS physical server to VMware ESXi using: These methods allow you to safely migrate physical Linux systems to virtual infrastructure for modernization, disaster recovery, hardware replacement, or virtualization projects.
Inside Modern Cybersecurity Companies: How Businesses Are Defending Email and Critical Infrastructure
Every business now depends on connected systems to communicate, store information, manage operations, and support customers. Email platforms handle sensitive conversations, Linux servers power cloud environments, and digital infrastructure keeps websites, applications, and internal networks running around the clock. While these technologies create efficiency and scalability, they also create opportunities for attackers looking to exploit weak points.
How to Run Linux on Hyper-V?
Running Linux on Hyper-V allows you to combine the stability of Microsoft’s virtualization platform with the versatility of open-source operating systems. Whether you’re exploring Linux for education, testing or production environments, Hyper-V provides a reliable way to deploy and manage virtual machines efficiently. Among the many supported distributions, Ubuntu Linux stands out for its simplicity and broad compatibility.
Dirty Frag Vulnerability (CVE-2026-43284 & CVE-2026-43500): Why Reliable Linux Privilege Escalation Changes the Defense Equation
Dirty Frag (comprising CVE-2026-43284 and CVE-2026-43500) is a high-impact Linux kernel vulnerability chain that enables deterministic, reliable local privilege escalation (LPE) to root across major enterprise distributions. Unlike previous race-condition exploits, this logic flaw in the IPsec ESP and RxRPC subsystems offers a near 100% success rate, allowing attackers to escalate from a minor foothold to full system control without triggering typical kernel panics.
"Copy Fail" Vulnerability (CVE-2026-31431): Linux Kernel Privilege Escalation
CVE-2026-31431— the “Copy Fail” vulnerability—is a critical local privilege escalation (LPE) flaw in the Linux kernel’s cryptographic subsystem that allows unprivileged users to gain root access with near-perfect reliability. Boasting a CVSS score of 7.8 and affecting nearly every mainstream distribution since 2017 (including Ubuntu, RHEL, and Amazon Linux), Copy Fail has been added to the CISA KEV catalog due to its active exploitation and portable, low-footprint nature.
CVE-2026-31431 (Copy Fail): Linux Kernel LPE
A new Linux kernel LPE disclosed by Theori/Xint lets any unprivileged local user become root with a 732-byte Python script. Works first try, no race, no per-kernel offsets. CVSS 7.8 (High), effectively critical for shared-kernel and multi-tenant environments.
