Hello aspiring hackers. Today we will learn about Linux Configuration Enumeration POST Exploit. After getting a successful meterpreter session on the target Linux system (as shown here), the next logical step is to perform some enumeration on the target Linux machine. Metasploit has many POST exploits corresponding to Linux enumeration.
The first module we will see is Linux configuration enumeration. The enum_configs module is used to collect information from the configuration files found of applications commonly installed in the system. These applications may include Apache, Nginx, Snort, MySQL, Samba, Sendmail, sysctl, cups, lampp and SNMP etc. This POST module searches for a config file in the application’s default path and if the application exists on the target system, the module will download the files and store it.
If the application doesn’t exist or the config file is moved from its default location, this module will display the “file not found” message. (Just like any POST exploit or as shown in the shell_to_meterpreter exploit, we need to background the current session and load the POST module as shown above. Then set the session id and run the exploit). Here is the enum configs module in action as shown below.
Hello aspiring hackers. In this howto, we will learn how to hack remote PC with Git Submodule. If you are a developer, cyber security enthusiast or at least a computer user, you should have definitely used (or heard about) Github. Git is an open source version control system developed by none other than the awesome Linus Trovalds (yes the same guy who created Linux).
It is a system designed to keep in touch with constant changes made to the code of software by developers. GitHub is a popular hub where developers store their projects and network with like minded people. Github stores information in a data structure called a repository. The particular module exploits a vulnerability in Git submodule.
Git submodules allow users to attach an external repository inside another repository at a specific path. This vulnerability in the Git submodule can be exploited by an attacker who can change the URL of a sub- module in a repository. This URL in the submodule can be changed to point towards a malicious link.
This module is a local exploit and works on Git versions 2.7.5 and lower. Now let us see how this module works. Start Metasploit and load the exploit as shown below. Type command “show options” to see all the options we need for this module to run.
First, we need to configure the malicious Git server. Set the options : LHOST, git_uri and Iport options as shown below. The git_uri option sets the malicious git submodule. Use command “run” to start our Git server. As the user git clones from our URL, we will get a command session on the target.
Now we need to send this malicious Git url to our intended victims. Probably it should be set as a software to convince the users to clone into their machine. Here we are testing this on KaIi Linux 2016 machine which has the vulnerable version of Git installed. We need to instruct the user to update the submodule just cloned. Let us see what happens on the victim machine.
As this happens in our victim system, we will already get a command shell on our attacker system as shown below.
We can see the active sessions using the command “sessions”.
Hello aspiring hackers, till now we have only seen hacking windows operating systems with customized payload generators. Today we will see hacking Linux OS with Arcanus framework.
Although not as great as Windows, people using Linux OS are growing day by day. In my opinion, Linux OS is a bit easy to hack with payload generators as there is a general myth that Linux is immune to malware. Some of my friends use Linux as dual boot to keep themselves safe from virus.
