### Memory Dump
In order to obtain the memory of the running system it's recommended to use [**LiME**](https://github.com/504ensicsLabs/LiME).\
In order to **compile** it you need to use the **exact same kernel** the victim machine is using.

## Disk Imaging
### Disk Imaging
### Shutting down
#### Shutting down
First of all you will need to **shutdown the system**. This isn't always an option as some times system will be a production server that the company cannot afford to shutdown.\
There are **2 ways** of shutting down the system, a **normal shutdown** and a **"plug the plug" shutdown**. The first one will allow the **processes to terminate as usual** and the **filesystem** to be **synchronized**, but I will also allow the possible **malware** to **destroy evidences**. The "pull the plug" approach may carry **some information loss** (as we have already took an image of the memory not much info is going to be lost) and the **malware won't have any opportunity** to do anything about it. Therefore, if you **suspect** that there may be a **malware**, just execute the **`sync`** **command** on the system and pull the plug.
### Taking an image of the disk

It's important to note that **before connecting to your computer anything related to the case**, you need to be sure that it's going to be **mounted as read only** to avoid modifying the any information.

## Services
### Services
It is extremely common for malware to entrench itself as a new, unauthorized service. Linux has a number of scripts that are used to start services as the computer boots. The initialization startup script _**/etc/inittab**_ calls other scripts such as rc.sysinit and various startup scripts under the _**/etc/rc.d/**_ directory, or _**/etc/rc.boot/**_ in some older versions. On other versions of Linux, such as Debian, startup scripts are stored in the _**/etc/init.d/**_ directory. In addition, some common services are enabled in _**/etc/inetd.conf**_ or _**/etc/xinetd/**_ depending on the version of Linux. Digital investigators should inspect each of these startup scripts for anomalous entries.

## Kernel Modules
### Kernel Modules
On Linux systems, kernel modules are commonly used as rootkit components to malware packages. Kernel modules are loaded when the system boots up based on the configuration information in the `/lib/modules/'uname -r'` and `/etc/modprobe.d` directories, and the `/etc/modprobe` or `/etc/modprobe.conf` file. These areas should be inspected for items that are related to malware.

## Examine Logs
Look in all available log files on the compromised system for traces of malicious execution and associated activities such as creation of a new service.
## Pure Logs
### Pure Logs
**Logon** events recorded in the system and security logs, including logons via the network, can reveal that **malware** or an **intruder gained access** to a compromised system via a given account at a specific time. Other events around the time of a malware infection can be captured in system logs, including the **creation** of a **new** **service** or new accounts around the time of an incident.\

Linux system logs and audit subsystems may be disabled or deleted in an intrusion or malware incident.

## USB Logs
### USB Logs
[**usbrip**](https://github.com/snovvcrash/usbrip) is a small piece of software written in pure Python 3 which parses Linux log files (`/var/log/syslog*` or `/var/log/messages*` depending on the distro) for constructing USB event history tables.
It is interesting to **know all the USBs that have been used** and it will be more useful if you have an authorized list of USB to find "violation events" (the use of USBs that aren't inside that list).

# Review User Accounts and Logon Activities
## Review User Accounts and Logon Activities
Examine the _**/etc/passwd**_, _**/etc/shadow**_ and **security logs** for unusual names or accounts created and/or used in close proximity to known unauthorized events. Also check possible sudo brute-force attacks.\
Moreover, check files like _**/etc/sudoers**_ and _**/etc/groups**_ for unexpected privileges given to users.\
Finally look for accounts with **no passwords** or **easily guessed** passwords.
# Examine File System
## Examine File System
File system data structures can provide substantial amounts of **information** related to a **malware** incident, including the **timing** of events and the actual **content** of **malware**.\
**Malware** is increasingly being designed to **thwart file system analysis**. Some malware alter date-time stamps on malicious files to make it more difficult to find them with time line analysis. Other malicious code is designed to only store certain information in memory to minimize the amount of data stored in the file system.\

## Basic Information
Multicast DNS (mDNS) is a **zero-configuration protocol** that lets you perform **DNS-like operations** on the local network in the absence of a conventional, unicast DNS server. The protocol uses the **same** API, **packet formats**, and operating semantics as DNS, allowing you to resolve domain names on the local network. **DNS Service Discovery (DNS-SD)** is a protocol that allows clients to **discover a list of named instances of services** (such as test.\_ipps.\_tcp.local, or linux.\_ssh.\_tcp.local) in a domain using standard DNS queries. DNS-SD is most often used in conjunction with mDNS but isn’t dependent on it. They’re both used by many IoT devices, such as network printers, Apple TVs, Google Chromecast, Network-Attached Storage (NAS) devices, and cameras.\

**Finger** is a program you can use to find information about computer users. It usually lists the login name, the full name, and possibly other details about the user you are fingering. These details may include the office location and phone number \(if known\), login time, idle time, time mail was last read, and the user's plan and project files.

## Any variable
### Any variable
In some cases, user-supplied data can be treated as an Nginx variable. It’s unclear why this may be happening, but it’s not that uncommon or easy to test for as seen in this [H1 report](https://hackerone.com/reports/370094). If we search for the error message, we can see that it is found in the [SSI filter module](https://github.com/nginx/nginx/blob/2187586207e1465d289ae64cedc829719a048a39/src/http/modules/ngx\_http\_ssi\_filter\_module.c#L365), thus revealing that this is due to SSI.
One way to test for this is to set a referer header value:&#x20;

We scanned for this misconfiguration and found several instances where a user could print the value of Nginx variables. The number of found vulnerable instances has declined which could indicate that this was patched.
# Raw backend response reading
## Raw backend response reading
With Nginx’s `proxy_pass`, there’s the possibility to intercept errors and HTTP headers created by the backend. This is very useful if you want to hide internal error messages and headers so they are instead handled by Nginx. Nginx will automatically serve a custom error page if the backend answers with one. But what if Nginx does not understand that it’s an HTTP response?&#x20;

The [merge\_slashes](http://nginx.org/en/docs/http/ngx\_http\_core\_module.html#merge\_slashes) directive is set to “on” by default which is a mechanism to compress two or more forward slashes into one, so `///` would become `/`. If Nginx is used as a reverse-proxy and the application that’s being proxied is vulnerable to local file inclusion, using extra slashes in the request could leave room for exploit it. This is described in detail by [Danny Robinson and Rotem Bar](https://medium.com/appsflyer/nginx-may-be-protecting-your-applications-from-traversal-attacks-without-you-even-knowing-b08f882fd43d).

## What is Kerberos?
### What is Kerberos?
Firstly, Kerberos is an authentication protocol, not authorization. In other words, it allows to identify each user, who provides a secret password, however, it does not validates to which resources or services can this user access.
Kerberos is used in Active Directory. In this platform, Kerberos provides information about the privileges of each user, but it is responsability of each service to determine if the user has access to its resources.

It echoes the command to be executed to a bat file, redirects the stdout and stderr to a Temp file, then executes the bat file and deletes it. Back on Kali, the Python script then pulls the output file via SMB and displays the contents in our "pseudo-shell". For every command we type into our "shell", a new service is created and the process is repeated. This is why it doesn't need to drop a binary, it just executes each desired command as a new service. Definitely more stealthy, but as we saw, an event log is created for every command executed. Still a very clever way to get a non-interactive "shell"!
