SINCON 2021 Conference — Implementation of One-Way Shellcoding in Windows 64-bit Systems

SINCON 2021 Conference — Workshop

Day 1 (05 Nov 2021) 11.30am—5.30pm @ Workshop Room — Max Capacity: 20 pax

Implementation of One-Way Shellcoding in Windows 64-bit Systems

Abstract

Generally, the traditional shellcodes generated by exploit frameworks like MSFvenom for reverse/bind shell do not work as expected when the vulnerable server is behind a firewall. As the firewall rules block all inbound and outbound connections to/from the server, except for the vulnerable service port, We can communicate only with the port used by the vulnerable service. The scenario is very challenging for penetration testers and red teams to obtain a shell from the server because connections to/from all other ports in the server are blocked.


The goal of the workshop is to construct and demonstrate a shellcode that will work with such firewall restrictions and provide a shell from the server behind the firewall.
