Session
Data Link Layer is used for MAC to MAC communication, and encapsulates all information relating to IP, ports, session and application data. Most shells (remote access via terminals) use TCP/IP, requiring the information to traverse via the OSI stack, which the sending and receiving systems use to encode information a specific way for different processes to use (Raw socket programming, AD-Hoc Wi-Fi, Etc). This presentation will show a way Ethernet can be weaponized to evade common detections, and how information can be encoded on frames. The common consensus is that layer 2 has range limitations, mainly due to the broadcast domain. Some bypasses will be introduced that extend the range of layer 2 communication.
