The Known Beacons Attack (34th Chaos Communication Congress)

The recent key reinstallation attacks (KRACK) against the WPA2 protocol revealed how an adversary can easily eavesdrop, and in some cases tamper, a Wi-Fi connection secured by the WPA2 protocol. At the same time, Wi-Fi automatic association attacks achieve a similar result (man-in-the-middle position) not by attacking the WPA2 protocol directly but by enforcing Wi-Fi clients to join a rogue Access Point.

shadow v2 public release

About four months ago (April 2017), Vasilis Tsaousoglou and myself presented our work on exploiting Android's libc allocator at the 2017 INFILTRATE conference (Miami, Florida). Since version 5.0, Android has adopted the jemalloc allocator as its default libc malloc(3) implementation. For our talk we extended our previously released jemalloc heap exploration and exploitation tool called 'shadow' to support Android (both ARM32 and ARM64), and demonstrated its use on understanding the impact of libc heap corruption vulnerabilities. We also presented new jemalloc/Android-specific exploitation techniques for double free and arbitrary free vulnerabilities.

Lure10: Exploiting Windows Automatic Association Algorithm

Lure10 is a novel technique presented at the Hack-in-the-Box 2017 conference in Amsterdam that enables an attacker to automatically achieve a man-in-the-middle position against wireless devices running the Windows operating system. The attack requires no user interaction and exploits the "Wi-Fi Sense" feature found in recent versions of the Microsoft Windows platform.

Hack In The Box 2017 Amsterdam

CENSUS researcher George Chatzisofroniou presented a novel WiFi attack technique named 'Lure10' at the CommSec track of the Hack In the Box 2017 conference in Amsterdam. The technique allows the automatic association of a Windows device to an attacker-controlled WiFi access point. The attacker may then mount a series of Man-in-the-Middle attacks to the victim device.
