AirSnitch: Breaking Wi-Fi Client Isolation: Technique Index, Tool Usage & Defenses This morning I came across another interesting paper submitted at the NDSS Symposium 2026 like the BLERP paper already documented in this forum, but this time challenging the Wi-Fi client isolation th...

Think your guest Wi-Fi is isolated from your main network? Think again.

BLERP: BLE Re-Pairing Attacks and Defenses Introduction Last week Daniele Antonioli posted an interesting paper and tooling (two nRF52840 boards, custom NimBLE btshell + Scapy-based Python Host for the double-channel MitM), he did with Tommaso...

Something new in our community and that deserves more attention: Breakdown of BLERP, the BLE re-pairing attacks by
Daniele Antonioli
& Sacchetti (NDSS 2026). TL;DR: the BLE standard doesn't authenticate re-pairing.

POV: you demo a vulnerability on stage in 2019, release a full exploitation tool (V2GInjector), present it at conferences and then get silent for some years...

...and in 2025 it finally gets a CVE because someone else reported it to CISA πŸ’€

At least they credited us. Thanks CISA 🀝
