serpentine is a Windows RAT (Remote Administration Tool) that lets you interact with the clients using a multiplatform RESTful C2 server.
Functionalities:
-
Startup
-
Get files
-
Put files
-
Keylogger (Just get
%APPDATA%/svchost/log
file) -
Reverse shell (Using
netcat
as a client, listen on a portnc -l -p 5555
and request a reverse shell connection to that port) -
Reverse proxy (Using
revp
, uploadrevp
to the client and execute it with a reverse shell) -
Take screenshots
-
Remote desktop (Using
qtserpentine
frontend) [Work in progress, sending input is still in development]
client
directory holds the Windows portion of the RAT made with C++ and Boost.
server
holds the RESTful server portion made with Java and Spring.
frontend
can hold any number of frontends that consume the RESTful API, currently holds goserpentine
terminal client and qtserpentine
GUI client.
Build server
with mvn package
and then run the JAR with 2 arguments, first being the client-listening port and second the port RESTful API will be served at. Example: java -jar target/serpentine-0.1.0.jar 2222 8080
Build client
with Visual Studio and also include Boost libraries: https://www.boost.org/doc/libs/1_73_0/more/getting_started/windows.html
Change client
settings in config.h
.
Build goserpentine
frontend
with go build
and run the resulting executable to see the list of options.
Build qtserpentine
by installing Qt Creator and building through that. Provide QTSERPENTINE_API_ADDRESS
environment variable that points to the API server.
(To learn more about the endpoints and input parameters check the controllers in server code)
