Not all properties displayed

Closed 1 year ago.
This is a follow-up question from PowerShell | EVTX | Compare Message with Array (Like)
I changed the tactic slightly, now I am collecting all the services installed,
$7045 = Get-WinEvent -FilterHashtable #{ Path="1system.evtx"; Id = 7045 } | select
#{N=’Timestamp’; E={$_.TimeCreated.ToUniversalTime().ToString('yyyy-MM-ddTHH:mm:ssZ')}},
Id,
#{N=’Machine Name’; E={$_.MachineName}},
#{N=’Service Name’; E={$_.Properties[0].Value}},#{N=’Image Path’;E=$_.Properties[1].Value}},
#{N=’RunAsUser’; E={$_.Properties[4].Value}},#{N=’Installed By’; E={$_.UserId}}
Now I match each object for any suspicious traits and if found, I add a column 'Suspicious' with the value 'Yes'. This is because I want to leave the decision upto the analyst and pretty sure the bad guys might use something we've not seen before.
foreach ($Evt in $7045)
{
if ($Evt.'Image Path' -match $sus)
{
$Evt | Add-Member -MemberType NoteProperty -Name 'Suspicious' -Value 'Yes'
}
}
Now, I'm unable to get PowerShell to display all columns unless I specifically Select them
$7045 | Format-Table
Same goes for CSV Export. The first two don't include the Suspicious Column but the third one does but that's because I'm explicitly asking it to.
$7045 | select * | Export-Csv -Path test.csv -NoTypeInformation
$7045 | Export-Csv -Path test.csv -NoTypeInformation
$7045 | Select-Object Timestamp, Id, 'Machine Name', 'Service Name', 'Image Path', 'RunAsUser', 'Installed By', Suspicious | Export-Csv -Path test.csv -NoTypeInformation
I read the Export-CSV documentation on MS. Searched StackOverFlow for some tips, I think it has something to do with PS checking the first Row and then compares if the property exists for the second row and so on.
Thank you
The issue you're experiencing is partially because of how objects are displayed to the console, the first object's Properties determines the displayed Properties (Columns) to the console.
The bigger problem though, is that Export-Csv will not export those properties that do not match with first object's properties unless they're explicitly added to the remaining objects or the objects are reconstructed, for this one easy way is to use Select-Object as you have pointed out in the question.
Given the following example:
$test = #(
[pscustomobject]#{
A = 'ValA'
}
[pscustomobject]#{
A = 'ValA'
B = 'ValB'
}
[pscustomobject]#{
C = 'ValC'
D = 'ValD'
E = 'ValE'
}
)
Format-Table will not display the properties B to E:
$test | Format-Table
A
-
ValA
ValA
Format-List can display the objects properly, this is because each property with it's corresponding value has it's own console line in the display:
PS /> $test | Format-List
A : ValA
A : ValA
B : ValB
C : ValC
D : ValD
E : ValE
Export-Csv and ConvertTo-Csv will also miss properties B to E:
$test | ConvertTo-Csv
"A"
"ValA"
"ValA"
You have different options as a workaround for this, you could either add the Suspicious property to all objects and for those events that are not suspicious you could add $null as Value.
Another workaround is to use Select-Object explicitly calling the Suspicious property (this works because you know the property is there and you know it's Name).
If you did not know how many properties your objects had, a dynamic way to solve this would be to discover their properties using the PSObject intrinsic member.
using namespace System.Collections.Generic
function ConvertTo-NormalizedObject {
[CmdletBinding()]
param(
[Parameter(ValueFromPipeline, Mandatory)]
[object[]] $InputObject
)
begin {
$list = [List[object]]::new()
$props = [HashSet[string]]::new([StringComparer]::InvariantCultureIgnoreCase)
}
process {
foreach($object in $InputObject) {
$list.Add($object)
foreach($property in $object.PSObject.Properties) {
$null = $props.Add($property.Name)
}
}
}
end {
$list | Select-Object ([object[]] $props)
}
}
Usage:
# From Pipeline
$test | ConvertTo-NormalizedObject | Format-Table
# From Positional / Named parameter binding
ConvertTo-NormalizedObject $test | Format-Table
Lastly, a pretty easy way of doing it thanks to Select-Object -Unique:
$prop = $test.ForEach{ $_.PSObject.Properties.Name } | Select-Object -Unique
$test | Select-Object $prop
Using $test for this example, the result would become:
A B C D E
- - - - -
ValA
ValA ValB
ValC ValD ValE
Continuing from my previous answer, you can add a column Suspicious straight away if you take out the Where-Object filter and simply add another calculated property to the Select-Object cmdlet:
# create a regex for the suspicious executables:
$sus = '(powershell|cmd|psexesvc)\.exe'
# alternatively you can join the array items like this:
# $sus = ('powershell.exe','cmd.exe','psexesvc.exe' | ForEach-Object {[regex]::Escape($_)}) -join '|'
$7045 = Get-WinEvent -FilterHashtable #{ LogName = 'System';Id = 7045 } |
Select-Object Id,
#{N='Timestamp';E={$_.TimeCreated.ToUniversalTime().ToString('yyyy-MM-ddTHH:mm:ssZ')}},
#{N='Machine Name';E={$_.MachineName}},
#{N='Service Name'; E={$_.Properties[0].Value}},
#{N='Image Path'; E={$_.Properties[1].Value}},
#{N='RunAsUser'; E={$_.Properties[4].Value}},
#{N='Installed By'; E={$_.UserId}},
#{N='Suspicious'; E={
if ($_.Properties[1].Value -match $sus) { 'Yes' } else {'No'}
}}
$7045 | Export-Csv -Path 'X:\Services.csv' -UseCulture -NoTypeInformation
Because you have many columns, this will not fit the console width anymore if you do $7045 | Format-Table, but the CSV file will hold all columns you wanted.
I added switch -UseCulture to the Export-Csv cmdlet, which makes sure you can simply double-click the csv file so it opens correctly in your Excel.
As sidenote: Please do not use those curly so-called 'smart-quotes' in code as they may lead to unforeseen errors. Straighten these ’ thingies and use normal double or single quotes (" and ')
I have deleted my original question because I believe I have a more efficient way to run my script, thus I'm changing my question.
$scrubFileOneDelim = "|"
$scrubFileTwoDelim = "|"
$scrubFileOneBal = 2
$scrubFileTwoBal = 56
$scrubFileOneAcctNum = 0
$scrubFileTwoAcctNum = 0
$ColumnsF1 = Get-Content $scrubFileOne | ForEach-Object{($_.split($scrubFileOneDelim)).Count} | Measure-Object -Maximum | Select-Object -ExpandProperty Maximum
$ColumnsF2 = Get-Content $scrubFileTwo | ForEach-Object{($_.split($scrubFileTwoDelim)).Count} | Measure-Object -Maximum | Select-Object -ExpandProperty Maximum
$useColumnsF1 = $ColumnsF1-1;
$useColumnsF2 = $ColumnsF2-1;
$fileOne = import-csv "$scrubFileOne" -Delimiter "$scrubFileOneDelim" -Header (0..$useColumnsF1) | select -Property #{label="BALANCE";expression={$($_.$scrubFileOneBal)}},#{label="ACCTNUM";expression={$($_.$scrubFileOneAcctNum)}}
$fileTwo = import-csv "$scrubFileTwo" -Delimiter "$scrubFileTwoDelim" -Header (0..$useColumnsF2) | select -Property #{label="BALANCE";expression={$($_.$scrubFileTwoBal)}},#{label="ACCTNUM";expression={$($_.$scrubFileTwoAcctNum)}}
$hash = #{}
$hashTwo = #{}
$fileOne | foreach { $hash.add($_.ACCTNUM, $_.BALANCE) }
$fileTwo | foreach { $hashTwo.add($_.ACCTNUM, $_.BALANCE) }
In this script I'm doing the following, counting header's to return the count and use it in a range operator in order to dynamically insert headers for later manipulation. Then I'm importing 2 CSV files. I'm taking those CSV files and pushing them into their own hashtable.
Just for an idea of what I'm trying to do from here...
CSV1 (as a hashtable) looks like this:
Name Value
---- -----
000000000001 000000285+
000000000002 000031000+
000000000003 000004685+
000000000004 000025877+
000000000005 000000001+
000000000006 000031000+
000000000007 000018137+
000000000008 000000000+
CSV2 (as a hashtable) looks like this:
Name Value
---- -----
000000000001 000008411+
000000000003 000018137+
000000000007 000042865+
000000000008 000009761+
I would like to create a third hash table. It will have all the "NAME" items from CSV2, but I don't want the "VALUE" from CSV2, I want it to have the "VALUE"s that CSV1 has. So in the end result would look like this.
Name Value
---- -----
000000000001 000000285+
000000000003 000004685+
000000000007 000018137+
000000000008 000000000+
Ultimately I want this to be exported as a csv.
I have tried this with just doing a compare-object, not doing the hashtables with the following code, but I abandoned trying to do it this way because file 1 may have 100,000 "accounts" where file 2 only has 200, and the result I was getting listed close to the 100,000 accounts that I didn't want to be in the result. They had the right balances but I want a file that only has those balances for the accounts listed in file 2. This code below isn't really a part of my question, just showing something I've tried. I just think this is much easier and faster with a hash table now so I would like to go that route.
#Find and Rename the BALANCE and ACCOUNT NUMBER columns in both files.
$fileOne = import-csv "$scrubFileOne" -Delimiter "$scrubFileOneDelim" -Header (0..$useColumnsF1) | select -Property #{label="BALANCE";expression={$($_.$scrubFileOneBal)}},#{label="ACCT-NUM";expression={$($_.$scrubFileOneAcctNum)}}
$fileTwo = import-csv "$scrubFileTwo" -Delimiter "$scrubFileTwoDelim" -Header (0..$useColumnsF2) | select -Property #{label="BALANCE";expression={$($_.$scrubFileTwoBal)}},#{label="ACCT-NUM";expression={$($_.$scrubFileTwoAcctNum)}}
Compare-Object $fileOne $fileTwo -Property 'BALANCE','ACCTNUM' -IncludeEqual -PassThru | Where-Object{$_.sideIndicator -eq "<="} | select * -Exclude SideIndicator | export-csv -notype "C:\test\f1.txt"
What you are after is filtering the Compare-Object function. This will show only one side of the result. YOu will need to place this before you exclude that property for it to work.
| Where-Object{$_.sideIndicator -eq "<="} |
Assuming that you have the following hash tables:
$hash = #{
'000000000001' = '000000285+';
'000000000002' = '000031000+';
'000000000003' = '000004685+';
'000000000004' = '000025877+';
'000000000005' = '000000001+';
'000000000006' = '000031000+';
'000000000007' = '000018137+';
'000000000008' = '000000000+';
}
$hashTwo = #{
'000000000001' = '000008411+';
'000000000003' = '000018137+';
'000000000007' = '000042865+';
'000000000008' = '000009761+';
}
you can create the third hash table by iterating over the keys from the second hash table and then assigning those keys to the value from the first hash table.
$hashThree = #{}
ForEach ($key In $hashTwo.Keys) {
$hashThree["$key"] = $hash["$key"]
}
$hashThree
The output of $hashThree is:
Name Value
---- -----
000000000007 000018137+
000000000001 000000285+
000000000008 000000000+
000000000003 000004685+
If you want the order of the data maintained (and you are using PowerShell 6 Core), you can use [ordered]#{} when creating the hash tables.
I will do my best to break this down as simply as I can.
what I have so far that is working:
Currently I have two csv files...
test1.csv
test1ColumnN,test1ColumnI,test1ColumnD,selectDomainOne,selectDomainTwo,selectDomainThree
asdf,asdf,asdf,,,
nValue1,iValue1,dValue1,sValue1,,
qwer,asdf,zxcv,,,
nValue2,iValue2,dValue2,,,
qwer,zxcv,asdf,lkjh,,
nValue3,iValue3,dValue3,sValue3,,
zxcv,qwer,asdf,,poiu,
nValue1,iValue1,dValue1,,sValue1,
nValue4,iValue4,dValue4,,sValue4,
asdf,qwer,zxcv,fghj,mnbv,
nValue5,iValue5,dValue5,,,
asdf,cvbn,erty,,,uytr
nValue7,iValue7,dValue7,,,sValue7
nValue8,iValue8,dValue8,,,sValue8
nValue9,iValue9,dValue9,,,sValue9
qwer,asdf,zxcv,poiu,lkjh,mnbv
test2.csv
DomainCatagories,test2ColumnS,test2ColumnA,test2ColumnN,test2ColumnI,test2ColumnD
DomainOne,sValue1,aValue1,nValue1,,dValueN
DomainOne,sValue2,aValue2,,iValue2,dValue2
DomainOne,sValue3,aValue2,nValue3,iValue3,dValue3
DomainTwo,sValue1,aValue2,,iValue1,dValueN
DomainTwo,sValue4,aValue1,nValue4,,dValueN
DomainTwo,sValue5,aValue1,nValue5,iValue5,dValue5
DomainThree,sValue7,aValue2,nValue7,iValue7,dValue7
DomainThree,sValue8,aValue1,nValue8,iValue8,dValue8
DomainThree,sValue9,aValue2,nValue9,iValue9,dValue9
Now I want to add a column (inside test2.csv) to match the sValue# from both test1.csv and test2.csv with the condition of ($_.DomainCatagories='DomainOne' from test2.csv) and ($_.selectDomainOne from test1.csv)
To do this, I am using the following code...
#Create Column
$domainNameOne = #{}
$domainNameOne = Import-Csv 'C:\Scripts\Tests\test1.csv' | Where-Object {$_.selectDomainOne} | Select-Object -Expand 'selectDomainOne'
(Import-Csv 'C:\Scripts\Tests\test2.csv') |
Select-Object -Property *, #{n='Test1sValues';e={
if($_.DomainCatagories -eq 'DomainOne'){
if(($domainNameOne -contains $_.test2ColumnS) -and ($_.test2ColumnS)){
$_.test2ColumnS
} Else {
'Not found in test1'
}}}} | Export-Csv "C:\Scripts\Tests\test2-Temp" -NoType
Move-Item "C:\Scripts\Tests\test2-Temp" 'C:\Scripts\Tests\test2.csv' -Force
After the code is run, I get the following test2.csv (isCorrect)...
"DomainCatagories","test2ColumnS","test2ColumnA","test2ColumnN","test2ColumnI","test2ColumnD","Test1sValues"
"DomainOne","sValue1","aValue1","nValue1","","dValueN","sValue1"
"DomainOne","sValue2","aValue2","","iValue2","dValue2","Not found in test1"
"DomainOne","sValue3","aValue2","nValue3","iValue3","dValue3","sValue3"
"DomainTwo","sValue1","aValue2","","iValue1","dValueN",""
"DomainTwo","sValue4","aValue1","nValue4","","dValueN",""
"DomainTwo","sValue5","aValue1","nValue5","iValue5","dValue5",""
"DomainThree","sValue7","aValue2","nValue7","iValue7","dValue7",""
"DomainThree","sValue8","aValue1","nValue8","iValue8","dValue8",""
"DomainThree","sValue9","aValue2","nValue9","iValue9","dValue9",""
What I have that is not working:
Next I run the following code...
#Append Column
$domainNameThree = #{}
$domainNameThree = Import-Csv 'C:\Scripts\Tests\test1.csv' | Where-Object {$_.selectDomainThree} | Select-Object -Expand 'selectDomainThree'
(Import-Csv 'C:\Scripts\Tests\test2.csv') | % {
if($_.DomainCatagories -eq 'DomainThree'){
if(($domainNameThree -contains $_.test2ColumnS) -and ($_.test2ColumnS)){
$_.Test1sValues = $_.test2ColumnS
} Else {
$_.Test1sValues = 'Not found in test1'
}}} | Export-Csv "C:\Scripts\Tests\test2-Temp" -NoType
Move-Item "C:\Scripts\Tests\test2-Temp" 'C:\Scripts\Tests\test2.csv' -Force
Instead of adding the values in the correct rows, it completely blanks out the whole file and saves it as an empty file.
End Goal
What I want the code to produce, is this (notice values filled in on last 3 rows in the last column)...
"DomainCatagories","test2ColumnS","test2ColumnA","test2ColumnN","test2ColumnI","test2ColumnD","Test1sValues"
"DomainOne","sValue1","aValue1","nValue1","","dValueN","sValue1"
"DomainOne","sValue2","aValue2","","iValue2","dValue2","Not found in test1"
"DomainOne","sValue3","aValue2","nValue3","iValue3","dValue3","sValue3"
"DomainTwo","sValue1","aValue2","","iValue1","dValueN",""
"DomainTwo","sValue4","aValue1","nValue4","","dValueN",""
"DomainTwo","sValue5","aValue1","nValue5","iValue5","dValue5",""
"DomainThree","sValue7","aValue2","nValue7","iValue7","dValue7","sValue7"
"DomainThree","sValue8","aValue1","nValue8","iValue8","dValue8","sValue8"
"DomainThree","sValue9","aValue2","nValue9","iValue9","dValue9","sValue9"
What am I doing wrong in that 2nd code snippet?
The example you show from What I have that is not working: is missing a key portion. Export-Csv will take everything piped into it to populate the CSV but you are not providing any.
Problem is that you are not passing anything through the pipe. Merely just updating one property. The simplest thing to do is add $_ after the if statement. Or you could just use a calculated property which you have done before in another one of your questions. The example below from Compare dates with different formats in csv file even uses an if statement.
Import-Csv $csvFile | Select-Object *, #{n='MatchDates';e={ if((([datetime]$_.Date1).Date -eq $_.Date3) -and (([datetime]$_.Date2).Date -eq $_.Date3) -and (([datetime]$_.Date1).Date -eq $_.Date2)){ 'Match Found' }Else{ 'No Match Found' }}} |
Export-Csv "$csvFile-results.csv" -NoTypeInformation -Force
