AirSnitch: Cross-Layer Wi-Fi Identity Desynchronization

⚠️AirSnitch exploits cross-layer identity desynchronization between Layers 1 and 2 to mount full, bidirectional machine-in-the-middle attacks. An attacker on the same SSID, a different SSID, or another segment tied to the same AP can intercept and modify link-layer traffic. The technique affects home, office, and enterprise Wi‑Fi and enables DNS poisoning, credential theft, and exploitation of unpatched flaws.

Dynamic Path MTU Discovery in the Cloudflare One Client

🔧 The Cloudflare One Client now implements Path MTU Discovery to detect and avoid PMTUD black holes that silently drop large encrypted packets. Using active probes over MASQUE (built on Cloudflare’s QUIC library), the client tests packet sizes end-to-end and dynamically adjusts the virtual interface MTU. This non-disruptive background process preserves sessions across shifting networks — for example, when moving from Wi‑Fi to cellular — preventing stalled uploads, calls, or SSH sessions. The feature is available for Windows, macOS, and Linux.

Automatic Return Routing for Overlapping IP Addresses

🔁 Automatic Return Routing (ARR) is a new Cloudflare One feature, released in Closed Beta, that resolves private IP address overlap by tracking flows and returning traffic to the exact tunnel that originated the conversation. Instead of depending on routing-table lookups, ARR uses stateful flow memory to record the originating tunnel and enforce symmetric returns. This approach minimizes the need for VRF or NAT, reducing operational overhead for mergers, extranets, and uniform branch deployments while integrating with Unified Routing and the Apollo userspace hub.

Cloudflare One boosts proxy mode performance with QUIC

🚀 Cloudflare rebuilt the Cloudflare One Client’s proxy mode to use QUIC streams and HTTP/3 CONNECT, removing the prior L4→L3 translation via smoltcp and deprecating WireGuard for proxy mode. The change keeps traffic at Layer 4, enabling native congestion and flow control, transport tunability, and substantially better throughput and latency in internal tests. Administrators should upgrade to minimum client version 2025.8.779.0 and enable MASQUE local proxy mode to benefit from these gains.

AWS Pricing for VPC Encryption Controls Moves to Paid

🔒 AWS is introducing pricing for VPC Encryption Controls, a regional capability that audits and enforces encryption-in-transit for traffic within and across Virtual Private Clouds. The feature supports Monitor mode to detect unencrypted flows and Enforce mode to prevent the creation or operation of resources that allow unencrypted traffic. Beginning March 1, 2026, AWS will apply a fixed hourly charge to every non-empty VPC with Encryption Controls enabled; empty VPCs enabled with the feature are not charged. When encryption is enabled on a Transit Gateway, standard VPC Encryption Controls charges apply to all VPCs attached to that Transit Gateway regardless of each VPC's mode or whether they are empty.

ASPA Deployment and Roadmap for More Secure Routing

🔒 ASPA (Autonomous System Provider Authorization) introduces cryptographic path validation to reduce route leaks by allowing networks to publish signed lists of authorized upstream providers in RPKI. Unlike ROAs, which verify prefix origins, ASPA validates the AS_PATH and detects routing "valleys" that indicate leaks. Cloudflare Radar now tracks ASPA adoption across RIRs and provides per‑AS visibility so operators can see whether observed upstreams are ASPA‑authorized and monitor changes over time.

January 22, 2026 IPv6 BGP Route Leak from Miami Data Center

⚠️On January 22, 2026, an automated routing policy change caused Cloudflare to unintentionally advertise IPv6 routes from a Miami router for 25 minutes. The misconfiguration accepted internal IBGP routes and redistributed them to peers and transit providers, funneling non-Cloudflare traffic into Miami and causing congestion, elevated packet loss, and higher latency on backbone links. Firewall filters on the router discarded around 12 Gbps of ingress traffic for those non-downstream prefixes. Cloudflare paused automation, reverted the change, restored normal operation, and apologized to affected users, customers, and external networks.
