In this chapter, we will cover the following topics:
In this chapter, we will explore using multiple methods to maintain access. For best results, multiple hosts and multiple methodologies should be employed. We will also discuss how we cover our tracks to make it easier to hide our activity.
In this recipe, we will leverage a host as a beachhead to exploit other hosts.
While this recipe may not sound appropriate for the topic of the chapter, one of the best ways of maintaining access to a target network is to have more hosts exploited that you can use for your communication channel. You can also have them use various forms of methods to reach out, so that if one is discovered you have access to others through different means.
Let's ensure the following prerequisites:
In this recipe, we will use persistence to maintain access to the system across reboots.
Let's ensure the following prerequisites:
In this recipe we will use persistence methods to maintain access to a system:
In this recipe, we will use cymothoa to maintain Linux system access through the use of a backdoor.
Let's ensure the following prerequisites:
To create a backdoor in Linux, we will use the following recipe:
In this recipe we will use pingtunnel to tunnel communications between two hosts. As most of the time, ICMP communications are allowed through firewalls and rarely inspected for malicious traffic by most companies, it makes it easy to set up a connection that will largely go unnoticed.
Let's ensure the following prerequisites:
To tunnel...
In this recipe we will use httptunnel to tunnel communications between two hosts. As most of the time, HTTP communications are allowed through firewalls with little inspection by most companies, it makes it easy to set up a connection that will largely go unnoticed.
Let's ensure the following prerequisites:
To create a tunnel with httptunnel...
In this recipe we will use cryptcat to transfer files between two hosts. Although we will use cryptcat for transferring files in this example, it can be used for a wide variety of purposes such as secure chat, shell access, port scanning as well as others.
Let's ensure the following prerequisites:
To use cryptcat to create tunnels to...
