} Btw as you can see we can use normal strings in our shellcode. This is because we include the .rdata section into our shellcode at linking time. And GET_SYMBOL gets the pointer to the function or string via its relative offset to GetRIP()

Get Started Clone this project and you are ready to start git clone https://www.github.com/Cracked5pider/ShellcodeTemplate
Next you would need to change the project name in the makefile from ShellcodeTemplate to whatever you want Then you can compile the project by using make make // to compile x64 and x86

Dive : A Tool For Exploring Each Layer In A Docker Image

Dive is a tool for exploring a docker image, layer contents, and discovering ways to shrink the size of your Docker/OCI image.

To analyze a Docker image simply run dive with an image tag/id/digest:

dive <your-image-tag

or if you want to build your image then jump straight into analyzing it:

dive build -t <some-tag

Building on Macbook (supporting only the Docker container engine)

docker run –rm -it \
-v /var/run/docker.sock:/var/run/docker.sock \
-v “$(pwd)”:”$(pwd)” \
-w “$(pwd)” \
-v “$HOME/.dive.yaml”:”$HOME/.dive.yaml” \
wagoodman/dive:latest build -t .

Additionally you can run this in your CI pipeline to ensure you’re keeping wasted space to a minimum (this skips the UI):

CI=true dive <your-image Basic FeaturesShow Docker image contents broken down by layer

As you select a layer on the left, you are shown the contents of that layer combined with all previous layers on the right. Also, you can fully explore the file tree with the arrow keys.

Indicate what’s changed in each layer

Files that have changed, been modified, added, or removed are indicated in the file tree. This can be adjusted to show changes for a specific layer, or aggregated changes up to this layer.

Estimate “image efficiency”

The lower left pane shows basic layer info and an experimental metric that will guess how much wasted space your image contains. This might be from duplicating files across layers, moving files across layers, or not fully removing files. Both a percentage “score” and total wasted file space is provided.

Quick build/analysis cycles

You can build a Docker image and do an immediate analysis with one command: dive build -t some-tag .You only need to replace your docker buildcommand with the same dive buildcommand.

CI Integration

Analyze an image and get a pass/fail result based on the image efficiency and wasted space. Simply set CI=truein the environment when invoking any valid dive command.

Multiple Image Sources and Container Engines Supported

With the --sourceoption, you can select where to fetch the container image from:

dive <your-image–source

With valid sourceoptions as such:

* docker: Docker engine (the default option)
* docker-archive: A Docker Tar Archive from disk
* podman: Podman engine (linux only) InstallationUbuntu/Debian

wget https://github.com/wagoodman/dive/releases/download/v0.9.2/dive_0.9.2_linux_amd64.deb
sudo apt install ./dive_0.9.2_linux_amd64.deb

RHEL/Centos

curl -OL https://github.com/wagoodman/dive/releases/download/v0.9.2/dive_0.9.2_linux_amd64.rpm
rpm -i dive_0.9.2_linux_amd64.rpm

Arch Linux

Available as dive in the Arch User Repository (AUR).

yay -S dive

The above example assumes yayas the tool for installing AUR packages.

Mac

If you use Homebrew:

brew install dive

If you use MacPorts:

sudo port install dive

Or download the latest Darwin build from the releases page.

Windows

Download the latest release.

Go tools Requires Go version 1.10 or higher. CI IntegrationWhen running dive with the environment variable CI=truethen the dive UI will be bypassed and will instead analyze your docker image, giving it a pass/fail indication via return code. Currently there are three metrics supported via a .dive-cifile that you can put at the root of your repo:

rules:
# If the efficiency is measured below X%, mark as failed.
# Expressed as a ratio between 0-1.
lowestEfficiency: 0.95
# If the amount of wasted space is at least X or larger than X, mark as failed.
# Expressed in B, KB, MB, and GB.
highestWastedBytes: 20MB
# If the amount of wasted space makes up for [...]

X% or more of the image, mark as failed.
# Note: the base image layer is NOT included in the total image size.
# Expressed as a ratio between 0-1; fails if the threshold is met or crossed.

Get-RBCD-Threaded : Tool To Discover Resource-Based Constrained Delegation Attack Paths

Get-RBCD-Threaded is a tool to discover Resource-Based Constrained Delegation attack paths in Active Directory Environments

Based almost entirely on wonderful blog posts “Wagging the Dog: Abusing Resource-Based Constrained Delegation to Attack Active Directory” by Elad Shamir and “A Case Study in Wagging the Dog: Computer Takeover” by harmj0y. Read these two blog posts if you actually want to understand what is going on here. I honestly only half understand it all myself (and that’s being generous).

I don’t know how to C# well so I figured out how to communicate with a domain in C# by reading through the source code of SharpSploit and SharpView. How it works

Get-RBCD-Thread will query all Active Directory users, groups (minus privileged groups like “Domain Admins” and “BUILTIN\Administrators”), and computer objects in your current domain and compile a list of their SIDs. Get-RBCD-Threaded will then query AD for all DACLs on the computer objects in the domain. Each ACE in the DACLs will be checked to see if one of the user/group/computer SIDS has either “GenericAll”, “GenericWrite”, “WriteOwner”, or “WriteDacl” privileges on the computer object, or if the SIDS have “WriteProp” permissions on the ms-DS-Allowed-To-Act-On-Behalf-Of-Other-Identity attribute (GUID:3f78c3e5-f79a-46bd-a0b8-9d18116ddc79). If it does, then, well, you my friend are on your way to a Resource-Based Constrained Delegation attack! UsageCompile in Visual Studio. This uses Parallel.ForEach to spead up searching through the DACL object, so .NET v4 is minimum required. Options-u|-username=, Username to authenticate as

-p|-password=, Password for the user

-d|-domain=, Fully qualified domain name to authenticate to

-s|-searchforest, Discover domains and forests through trust relationships. Enumerate all domains and forests

-pwdlastset=, Filter computers based on pwdLastSet to remove stale computer objects. If you set this to 90, it will filter out computer objects whose pwdLastSet date is more than 90 days ago

-i|-insecure, Force insecure LDAP connect if LDAPS is causing connection issues.

-o|-outputfile=, Output to a CSV file. Provided full path to file and file name.

-h|-?|-help, Show the help options

You can now specify the username, password, and domain to authenticate to. If u/p/d options are blank, Get-RBCD-Threaded will atempt to authenticate to the domain in your current user context.

-o will output to a CSV file. Provide the full file path and file name to save the output to.

The default search specifies that port 636 be used to force LDAPS. This may cause issues. If you get an error saying something about the server not being available or similar, try the “-i” flag to remove the 636 port from the connect string.

“pwdLastSet” has been added as a filtering option. In larger environments you can get a lot of stale computer objects that no longer exist as the “destination” object int he ACL, and can’t really be used for the RBCD attack (at least not that I am aware of). Set pwdLastSet to a number of days. Example: “-pwdlastset=90” will filter out any computer objects from your results where the pwdLastSet date is greater or equal to 90 days ago from the current date and time.

Tested in an environment with 20k+ uses, groups, and computers (over 60k total objects). Get-RBCD-Thread took ~60 seconds to complete. By comparison, my hacked together PowerView commands in this gist to perform a similar search ran for several hours and never completed.

This tool will not perform the delegation attack for you. You’ll need to read Elad Shamir’s and harmj0y’s blogs to figure out how to do that. This will only help you find possible targets for the RBCD attack.

Example usage from my AD lab:
https://blogger.googleuser[...]

content.com/img/a/AVvXsEiaULH3JrJZVATe0m9FgbwMPWJovTNr9ByX9UgoH1V7xD2pO4fJJ_2jh3DdO0XzNTdD0of2C5GAKidopqwRiX8Hb-yNsjfpevuVXz5rPoi_Xd_ZzusKlbl39dIv-oLA734zL6SWz6el7dN0NF6bFyvhmktbTNgK_XgKCfSz9NdmBX69m8UDsAjywuhv=s829 DetectionsThis tool does nothing more than query Active Directory using LDAP queries, which may not be easy to detect. Netflow could possibly be used to detect large numbers of LDAP queries / traffic to one system.

The other possible way to detect this is through honeypot accounts. The idea would be to create a computer object that some user / group has write privileges to. The RBCD attack relies on modifying a computer object and then delegating kerberos tickets to it. The possible points of detection for the honeypot computer object could be:

1. Monitor modifications to the honeypot computer object, specifically to the “msds-allowedtoactonbehalfofotheridentity” property
2. Monitor for kerberos tickets requested for services on the honeypot computer object, specifically any kerberos tickets for administrator users

I made this tool to help me on penetration tests. However, defenders / blue teams / sysadmins can easily use this to help find weaknesses in their environments and (hopefully) move to remediate them. Download

An easily modifiable shellcode template for Windows x64/x86

How does it work?

This template is heavily based on Austin Hudson's (aka SecIdiot) TitanLdr It compiles the project into a PE Executable and extracts the .text section
Example

The entrypoint of the shellcode looks like this. Of course, this can be changed for your need. First we need to initialize needed libraries and functions by using our custom written GetModuleHandle and GetProcAddress.

SEC( text, B ) VOID Entry( VOID )
{
INSTANCE Instance = { };

Instance.Modules.Kernel32 = TGetModuleHandle( HASH_KERNEL32 );
Instance.Modules.Ntdll = TGetModuleHandle( HASH_NTDLL );

if ( Instance.Modules.Kernel32 != NULL )
{
// Load needed functions
Instance.Win32.LoadLibraryA = TGetProcAddr( Instance.Modules.Kernel32, 0xb7072fdb );

// Load needed Libraries
Instance.Modules.User32 = Instance.Win32.LoadLibraryA( GET_SYMBOL( "User32" ) );

if ( Instance.Modules.User32 != NULL )
{
Instance.Win32.MessageBoxA = TGetProcAddr( Instance.Modules.User32, 0xb303ebb4 );
}
}

// ------ Code ------
Instance.Win32.MessageBoxA( NULL, GET_SYMBOL( "Hello World" ), GET_SYMBOL( "MessageBox Title" ), MB_OK );
}

Btw as you can see we can use normal strings in our shellcode. This is because we include the .rdata section into our shellcode at linking time. And GET_SYMBOL gets the pointer to the function or string via its relative offset to GetRIP()
