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.

Security B-Sides 2017 Athens

CENSUS participated in the "Security B-Sides 2017 Athens" conference with a presentation by Ioannis Stais on the automated discovery of expressions that bypass Web Application Firewalls and Filters, using learning automata. The presentation was entitled "LightBulb Framework: Shedding Light on the Dark Side of WAFs and Filters" and followed Stais' and Argyros' previous research on the subject (see BlackHat Europe in 2016 presentation). The Security B-Sides presentation introduced an Extension for the Burp Suite web proxy application that allows for easier integration of the expression discovery technique to the standard toolbox of web application penetration testers.
