sliverarmory / armory Goto Github PK

Ayo! Any chance we can add SharPersist to the armory to add some persistence capabilities into sliver? Thanks!

I'm trying to port Defender_Exclusions-BOF, I see you already forked it, so I tried adding the extension.json and use it but no luck :(

[server] sliver (mtls-sk) > extensions install /home/kali/Downloads/Defender_Exclusions-BOF-main/dist

[*] Installing extension 'defender-excl' (1.0.0) ... 
[server] sliver (mtls-sk) > extensions load /home/kali/Downloads/Defender_Exclusions-BOF-main/dist

[*] Added defender-excl command: A BOF to determine Windows Defender exclusions:

[server] sliver (mtls-sk) > defender-excl 1

[!] Call extension error: rpc error: code = Unknown desc = The parameter is incorrect.

Hi, could you please update the current Nanodump module to support the PPL version of BOF - nanodump_ppl.x64.o with nanoduml_ppl.x64.dll from https://github.com/helpsystems/nanodump/tree/main/dist ?
Thanks

Hello! I'd love it if the following project could be imported into the armory please. Thank you!

https://github.com/sliverarmory/nopowershell

I've decided to modify mimikatz in order to be loaded as a DLL inside sliver implant. Here the repository: https://github.com/MrAle98/mimikatz. Open the project in visual studio 2019 and use sliverkatz build type in order to produce powerkatz.dll.

Here it is a screenshot of running dll powerkatz.dll in a sliver implant:

Hey for the moment It seems to me that there is no functionality similar to powerpick of cobalt-strike. I've found SharpPick at https://github.com/TheKevinWang/SharpPick that implements this functionality in C#. At the following links you can find the SharpPick repo with workflow and alias.json already added and the content to add to armory.json (I decided to do an additional private one):

• https://github.com/MrAle98/SharpPick
• https://github.com/MrAle98/armory

Maybe you can add it also to the official armory if you think could be useful.

I'd like to get Backstab added to Armory. Backstab is used to kill EDR by leveraging the ProcExp driver, which is signed by Microsoft. The project is up here: https://github.com/Yaxser/Backstab.

I created this fork (https://github.com/precurse-bf/Backstab) to add GA workflow. Once I finish up extension.json it should be good to go.

Hello I report here another extension that you may find useful.

I decided to modify chisel project to a windows DLL that can be loaded as an extension of a sliver agent, and manage multiple socks/port forwarding operations. Here the link to the repository with modified version of chisel supporting loading as sliver extension: https://github.com/MrAle98/chisel

The project now has two additional commands:

• list: shows currently running tasks in chisel
• stop taskId: stop a task identified by taskId (taskId are retrieved through list command)

I hope this extension to be useful when it is necessary to have a more powerful socks proxy without dropping anything to disk nor injecting in other processes.

It might be also considered as an example for showing how to introduce go tooling in C2s supporting the execution of DLLs in memory.

Build

Requires mingw-w64, it is already install on a kali linux instance.

With the following commands, chisel dlls are generated and is automatically created the extension chisel in sliver.

$ mkdir ~/.sliver-client/extensions/chisel
$ cp extension.json ~/.sliver-client/extensions/chisel
$ make windowsdll_64
$ make windowsdll_32

Run

Reverse socks proxy (server running on attacker box)

1. Start chisel server on attacker box.
   
2. Start chisel client in sliver agent.
   

Now on port 1080 on attacker box there is a socks proxy towards internal network.

Listing chisel tasks currently running.

Stop chisel client in sliver agent.

socks proxy (server running inside sliver agent)

1. start sliver server in sliver agent.
   
2. start client on attacker box.
   

Now on port 1081 on attacker box there is a socks proxy towards internal network.

Here output of netstat on attacker box.

Testing

I tested only x64 version of the dll not x86.
I just tested the extension on a x64 windows 10 pro build 10.0.19044.

Hey! Any chance of getting KrbRelayUp added to armory for some priv esc? Thanks in advance!

Request to add extension to armory https://github.com/c2biz/bof-collection

Thought it would be a nice idea to add functionality akin to rubeus tgtdeleg without remote process injection.

https://github.com/connormcgarr/tgtdelegation seems like a great fit, and I've tested that it works out-of-the-box with COFF here:

https://github.com/zimnyaa/tgtdeleg

Can we bring in the probe BOF from CS-Situational-Awareness-BOF?
Cheers!

Hello I've created this PR BishopFox/sliver#966 for adding commands to the client that can execute powershell and import powershell scripts in the implant process CLR. The PR was rejected because It uses directly, as raw binary, PS.exe powershell runner taken from PoshC2 repository. I've reversed PS.exe and created a repository with the source code here: https://github.com/MrAle98/PS.

It would be possible to add PS repository to the armory? Later i can modify the PR to fetch PS from the armory instead of embedding PS.exe binary inside the sliver-client.

Main reason for the PR is the feature request requested here: BishopFox/sliver#793

I'm looking to add EfsPotato, which exploits SeImpersonatePrivilege for local privilege escalation.

I forked the original project and added a GitHub actions pipeline with it here: https://github.com/precurse-bf/EfsPotato

When I performed an armory update, then armory install cs-remote-ops-bofs, I get the following error:
Failed to install ‘remote-setuserpass’: package not found

I am also getting the following error when just running the armory command:
failed to get signature for armory pkg ‘https://github.com/sliverarmory/CS-Remote-OPs-BOF’: 404 Not Found

Please import linpeas & winpeas.
