  • PhanTap (Phantom Tap)

    Friday from 10:00 – 11:50 in Sunset 2 at Planet Hollywood
    Audience: Red Teams, it could also be used by Blue Teams. Diana Dragusin & Etienne Champetier

    PhanTap (phantom tap) is an ‘invisible’ network tap aimed at red teams. With limited physical access to a target building, this tap can be installed inline between a network device and the corporate network. PhanTap is silent in the network and does not affect the victim’s traffic, even in networks having NAC (Network Access Control 802.1X - 2004). PhanTap will analyze traffic on the network and mask its traffic as the victim device. It will mount a tunnel back to a remote server, giving the attacker a foothold in the network for further exploitation and pivoting. The physical device for PhanTap is currently a small, inexpensive and disposable router running OpenWrt, we've been testing the GL.iNet GL-AR150. Moreover, PhanTap is fully based on Linux packages and can be ported to any Linux distribution.
