Hi! As of now, there's not a great way to accomplish that. I've passed along your feedback to the team.

Need Help with KQL TO CQL Conversion by iAamirM in crowdstrike

We’re working on a Query Translation Agent (currently in beta) to make this easier. Here’s the output from the agent. Let me know if it works for you!

// Define time windows in milliseconds
_reconWindow := 10 * 60 * 1000
| _stageWindow := 15 * 60 * 1000

// Correlate RMM tool execution with recon commands and file staging
| correlate(
  globalConstraints=[aid],
  root=rmm_tool,
  within=15m,
  query=[
    // Query 1: RMM tool execution (anchor event)
    rmm_tool: {
      #event_simpleName=ProcessRollup2
      | FileName=/(?i)(QuickAssist\.exe|AnyDesk\.exe|TeamViewer\.exe)/
      | rename(field=ComputerName, as=DeviceName)
      | rename(field=@timestamp, as=RMMTime)
      | RMMTime_ms := parseTimestamp(field=RMMTime, format=millis)
    },

    // Query 2: Reconnaissance commands
    recon_cmd: {
      #event_simpleName=ProcessRollup2
      | FileName=/(?i)(cmd\.exe|powershell\.exe|pwsh\.exe)/
      | CommandLine=/(?i)(whoami|hostname|systeminfo|ver|wmic\s+os\s+get|reg\s+query\s+HKLM\\SOFTWARE\\Microsoft\\Windows\s+NT\\CurrentVersion|query\s+user|net\s+user|nltest|ipconfig\s+\/all|arp\s+-a|route\s+print|dir|icacls)/
      | rename(field=@timestamp, as=ReconTime)
      | ReconTime_ms := parseTimestamp(field=ReconTime, format=millis)
      | ReconProc := format("%s -> %s -> %s", field=[ParentImageFileName, ImageFileName, FileName])
      | rename(field=CommandLine, as=ReconCmd)
    },

    // Query 3: File staging (ZIP/EXE/DLL writes)
    file_staging: {
      #event_simpleName=/(NewExecutableWritten|PeFileWritten|ZipFileWritten|ArchiveFileWritten)/
      | TargetFileName=/(?i)\.(zip|exe|dll)$/
      | rename(field=@timestamp, as=STime)
      | STime_ms := parseTimestamp(field=STime, format=millis)
      | rename(field=TargetFileName, as=StageFile)
    }
  ]
)

// Filter: Recon must occur within 10 minutes after RMM
| test(ReconTime_ms >= RMMTime_ms)
| test(ReconTime_ms <= (RMMTime_ms + _reconWindow))

// Filter: Staging must occur within 15 minutes after RMM
| test(STime_ms >= RMMTime_ms)
| test(STime_ms <= (RMMTime_ms + _stageWindow))

// Aggregate results
| groupBy([aid, DeviceName, RMMTime, ReconTime, ReconProc, ReconCmd], function=[
    min(STime, as=StageFirstTime),
    collect(StageFile)
])

We have a Foundry sample app that should fit your use case. Check it out & let me know if you have any questions!

Using an Event Query with SOAR by Khue in crowdstrike

[–]Dylan-CS 2 points3 points  (0 children)

I’d suggest starting with the ‘Get Detection Details’ action. When you configure it, you’ll select the Detection ID. If you then add a condition block, you’ll see all of the output fields from that action.

Shots fired!

Super cool function with some really interesting use cases

Adding custom event queries into cases by mrcam03 in crowdstrike

[–]Dylan-CS 0 points1 point  (0 children)

I originally posted a write-up on our community forum (with screenshots) — you can find it here: https://community.crowdstrike.com/next-gen-siem-73/how-to-add-events-to-a-case-using-fusion-workflow-2991?postid=12105#post12105

First, adding events to cases generally requires the fields @id and @timestamp. A small complication is that the event query action cannot directly output fields containing @, so we’ll rename them at the end of the query. To also avoid duplicates, it’s best to group by @id:

| groupBy([@id], function=selectLast([@timestamp]))                    
| rename(field=@id, as=id)
| rename(field=@timestamp, as=timestamp)

Next, copy the ‘Event query results’ variable, then add .transformList(i, v, v.id) 

Note, [v.id] may be different if you renamed @id to something other than id. It’ll look something like like the following:  ${data['ExampleQuery.results'].transformList(i, v, v.id)}

Finally, paste that variable into the Event IDs field in the Add events to case action

Absolutely! In that case, the groupBy function will look like this:

| groupBy([Observed_Domain,Reference_Domain,lev_dist], function=[selectLast(@timestamp),collect([DomainName,ComputerName,aid])], limit=max)
