Email and Remote Access Drive 90% of Cyber Claims in 2024

📧 At-Bay's 2025 InsurSec analysis finds email and remote access were central to 90% of cyber insurance claims in 2024. Email accounted for 43% of incidents and fraud schemes commonly begin with credential theft, domain spoofing, and impersonation. Google Workspace was cited as the most secure mail provider, though claims rose; MDR services were highlighted as the most reliable defense against full encryption.

Building a High-Performance VPN with Linux for WARP

🛡️ Cloudflare explains how it initially implemented WARP as a Layer‑3 VPN by leveraging the Linux networking stack to egress arbitrary user packets from edge machines. They used a TUN device, nftables/Netfilter rules and the conntrack module to perform NAT, mark flows, and distinguish client traffic from locally‑originated traffic. Core tunnel handling was written in Rust (boringtun/WireGuard) and paired with MASQUE and defense‑in‑depth controls. The approach worked but required one IPv4 address per server, creating a scalability and cost challenge that led them to explore IP sharing.

Widespread SonicWall SSL VPN Compromise Hits 100+ Accounts

🔒 Huntress warns of a widespread compromise of SonicWall SSL VPN devices that allowed threat actors to rapidly authenticate into multiple accounts across customer environments. Activity began on October 4, 2025, impacting over 100 VPN accounts across 16 customers, with logins traced to IP 202.155.8[.]73. While some intrusions disconnected quickly, others involved network scanning and attempts to access local Windows accounts. Organizations are urged to reset firewall credentials, restrict WAN management, revoke exposed API keys, monitor logins, and enforce MFA.

Resilient Network Security Strategies for Disruption

🔒 In a world where pandemics, war, and natural disasters are inevitable, security teams must plan for continuity. The article examines two primary approaches: scaling VPN capacity for remote access or adopting a SASE framework that integrates networking and security as a cloud-delivered service. Each option has trade-offs in cost, complexity, and operational risk; readiness requires assessing user patterns, threat exposure, and recovery objectives.
