Hello, I'm Nikos Sampanis, a security researcher working at CENSUS. On February 16th, 2018 I presented at OffensiveCon a talk with the title
"Windows 10 RS2/RS3 GDI data-only exploitation tales". The presentation focused on a
mitigation introduced in the Win32k component of Microsoft Windows to prevent the exploitation of memory
corruptions in the session heap (due to GDI object abuse).
CENSUS is proud to announce its participation in OffensiveCon 2018 as a Silver Sponsor.

Android provides a media playback engine at the native level called Stagefright that comes built-in with software-based codecs for several popular media formats. Stagefright features for audio and video playback include integration with OpenMAX codecs, session management, time-synchronized rendering, transport control, and DRM.

Kamailio (successor of former OpenSER and SER) is an Open Source SIP Server released under GPL, able to handle thousands of call setups per second. Kamailio can be used to build large platforms for VoIP and realtime communications, presence, WebRTC, Instant messaging and other applications. It can also easily be applied to scaling up SIP-to-PSTN gateways, PBX systems or media servers.
