Lunar - A Lightweight Native DLL Mapping Library That Supports Mapping Directly From Memory

A lightweight native DLL mapping library that supports mapping directly from memory

Features

Imports and delay imports are resolved
Relocations are performed
Image sections are mapped with the correct page protection
Exception handlers are initialised
A security cookie is generated and initialised
DLL entry point and TLS callbacks are called

Getting started
The example below demonstrates a simple implementation of the library

var libraryMapper = new LibraryMapper(process, dllBytes);

// Map the DLL into the process

libraryMapper.MapLibrary();

// Unmap the DLL from the process

libraryMapper.UnmapLibrary();

Constructors

LibraryMapper(Process, Memory<byte>)

Provides the functionality to map a DLL from memory into a remote process

LibraryMapper(Process, string)

Provides the functionality to map a DLL from disk into a remote process

Properties

DllBaseAddress

The base address of the DLL in the remote process after it has been mapped

Methods

MapLibrary()

Maps the DLL into the remote process

UnmapLibrary()

Unmaps the DLL from the remote process

Caveats

Mapping requires the presence of a PDB for ntdll.dll, and, so, the library will automatically download the latest version of this PDB from the Microsoft symbol server and cache it in %appdata%/Lunar/Dependencies

Learning Web Pentesting With DVWA Part 1: Installation

In this tutorial series I'm going to walk you through the damn vulnerable web application (DVWA) which is damn vulnerable. Its main goal according to the creators is "to aid security professionals to test thier skills and tools in a legal environment, help web developers better understand the process of securing web applications and to aid both students & teachers to learn about web application security in a controlled class room environment."

I am going to install DVWA in docker so the prerequisite for this tutorial will be an installation of docker (Docker is not the only way to install DVWA but if you have docker already installed then it may be the easiest way to install DVWA).

To install DVWA in docker run your docker deamon if it's not running already and open a terminal or powershell and type:

docker rum --rm -it -p 8080:80 vulnerables/web-dvwa

It will take some time to pull the image from docker hub depending on your internet speed and after it is complete it will start the dvwa application. In the command we have mapped the image instance's port 80 to our hosts port 8080 so we should be able to access the web application from our host at http://localhost:8080

Now open your favorite web browser and go to http://localhost:8080
You should be prompted with a login screen like this:

login with these creds:
username: admin
password: password

After login you'll see a database setup page since this is our first run. Click on Create / Reset Database button at the bottom. It will setup database and redirect you to login page. Now login again and you'll see a welcome page.

Now click on DVWA Security link at the bottom of the page navigation and make sure the security level is set to Low. If it is not click on the dropdown, select Low and then click submit.

Now our setup is complete, so lets try a simple SQL attack to get a taste of whats about to come.

Click on SQL Injection in navigation menu.
You'll be presented with a small form which accepts User ID.
Enter a single quote (') in the User ID input field and click Submit.
You'll see an SQL error like this:

From the error message we can determine that the server has a MariaDB database and we can see the point of injection.
Since there are many quotes we are not able to determine the exact location of our injection. Lets add some text after our single quote to see exactly where our injection point is.
Now I am going to enter 'khan in the User ID field and click Submit.

Now we can see exactly where the point of injection is. Determining the point of injection is very important for a successful SQL injection and is sometimes very hard too, though it might not be that much useful here in this exercise.

Now lets try the very basic SQL Injection attack.
In the User ID field enter ' or 1=1-- - and click Submit.

We will explain what is going on here in the next article.

adduser

The "adduser" command is a simple command used to create directly any user in the system. There is no need to make a group for this. You just have to type the command with user name like adduser Umer, it will created a user by name Umer.

Wafw00F: The Web Application Firewall Fingerprinting Tool

How does wafw00f work?
To do its magic, WAFW00F does the following steps:

Sends a normal HTTP request and analyses the response; this identifies a number of WAF solutions.

If that is not successful, wafw00f sends a number of (potentially malicious) HTTP requests and uses simple logic to deduce which WAF it is.

If that is also not successful, wafw00f analyses the responses previously returned and uses another simple algorithm to guess if a WAF or security solution is actively responding to wafw00f's attacks.

For further details, check out the source code on EnableSecurity's main repository.

What does it detect? WAFW00F can detect a number of firewalls, a list of which is as below:

wafw00f's installation
If you're using Debian-based distro, enter this commands to install wafw00f: sudo apt update && sudo apt install wafw00f

But if you're using another Linux distro, enter these commands to install wafw00f:

How to use wafw00f?
The basic usage is to pass an URL as an argument. Example:

Final Words to you
Questions? Pull up an issue on GitHub Issue Tracker or contact to EnableSecurity.
Pull requests, ideas and issues are highly welcome. If you wish to see how WAFW00F is being developed, check out the development board.

$$$ Bug Bounty $$$

What is Bug Bounty ?

A bug bounty program, also called a vulnerability rewards program (VRP), is a crowdsourcing initiative that rewards individuals for discovering and reporting software bugs. Bug bounty programs are often initiated to supplement internal code audits and penetration tests as part of an organization's vulnerability management strategy.

Many software vendors and websites run bug bounty programs, paying out cash rewards to software security researchers and white hat hackers who report software vulnerabilities that have the potential to be exploited. Bug reports must document enough information for for the organization offering the bounty to be able to reproduce the vulnerability. Typically, payment amounts are commensurate with the size of the organization, the difficulty in hacking the system and how much impact on users a bug might have.

Mozilla paid out a $3,000 flat rate bounty for bugs that fit its criteria, while Facebook has given out as much as $20,000 for a single bug report. Google paid Chrome operating system bug reporters a combined $700,000 in 2012 and Microsoft paid UK researcher James Forshaw $100,000 for an attack vulnerability in Windows 8.1. In 2016, Apple announced rewards that max out at $200,000 for a flaw in the iOS secure boot firmware components and up to $50,000 for execution of arbitrary code with kernel privileges or unauthorized iCloud access.

While the use of ethical hackers to find bugs can be very effective, such programs can also be controversial. To limit potential risk, some organizations are offering closed bug bounty programs that require an invitation. Apple, for example, has limited bug bounty participation to few dozen researchers.
