Riepilogo

Lo script disponibile in questo articolo illustra come gestire le modifiche apportate alle connessioni canale protetto Netlogon associate a CVE-2020-1472. Viene fornito così com'è.

Lo script elabora i file di EVTX esportati da Visualizzatore eventi e crea un foglio di calcolo di Microsoft Excel contenente tabelle pivot per i vari problemi e i dispositivi nell'ambiente che hanno generato gli eventi. Lo script richiede PowerShell e Microsoft Excel 2013 o versione successiva (64bit consigliato per set di dati più grandi).

uso

Sarà necessario esportare i EVTX file dai domain controller (DCS) che si stanno monitorando per i problemi descritti in KB4557222. A questo scopo, aprire Visualizzatore eventi selezionando Start, digitare Visualizzatore eventi e selezionarlo. Una volta aperto il Visualizzatore eventi, espandere i log di Windows, fare clic con il pulsante destro del mouse o premere a lungo sul sistema e selezionare Salva tutti gli eventi come.

Lo script può elaborare più EVTX file alla volta, se si vuole. Il completamento dello script può richiedere molto tempo in set di dati di grandi dimensioni. È anche consigliabile avere i EVTX file locali sullo stesso dispositivo che eseguono lo script per velocizzare l'elaborazione dei file.

Sarà necessario eseguire lo script in un prompt dei comandi di PowerShell. Non deve essere eseguito come amministratore. Lo script viene eseguito con le istruzioni che consentono di rispondere se necessario, a meno che non si imposti $mcScriptPrompts$false . Se i EVTX file si trovano nella stessa cartella dello script, non è necessario specificare un percorso per i file.

Personalizzare lo script

Variabile

Descrizione

$mcScriptPrompts

Valori $true,$false

Descrizione Il valore predefinito è $true e richiederà l'input/interazione dall'utente. Può essere impostato su $false se i EVTX file si trovano nella stessa cartella dello script e tutte le altre impostazioni verranno eseguite come predefinite.

$mcMaxExport

Valore predefinito: 50000

Descrizione Con le impostazioni predefinite, lo script smetterà di elaborare ogni EVTX file dopo aver esportato 50000 eventi ai CSV file. Se si riceve un errore relativo alla memoria di Microsoft Excel, è necessario abbassare il numero o modificare i dati in fase di processo, ad esempio la modifica della $mcStartTime .

$mcMaxImport

Valore predefinito: 50000

Descrizione Con le impostazioni predefinite, lo script smetterà di elaborarli dopo che il file CSV corrente verrà elaborato quando raggiunge il numero massimo di eventi 50000. Questo significa che, quando si raggiunge il numero massimo di eventi, completerà il CSV file corrente avviato, ma non inizierà a elaborare un nuovo CSV file.

$mcStartTime

Valore predefinito: '2020/05/26 11:06'

Descrizione Questa variabile consente di impostare un'ora di inizio e lo script elabora solo gli eventi dopo la data e l'ora. Se i dispositivi sono già stati risolti in un determinato punto, in questo modo è possibile assegnare solo gli eventi che non sono ancora stati risolti.

$mcMaxThreads

Valore predefinito: 4

Descrizione Questa variabile consente di aumentare o ridurre il numero di thread usati durante l'importazione degli eventi dai EVXT file ai CSV file.

 

Script

Di seguito è riportato lo script di PowerShell che può essere usato dopo aver personalizzato il proprio ambiente. Sarà necessario copiare e incollare questo script in un file nel CVE-2020-1472EventReader.ps1 dispositivo in uso per elaborare gli eventi.

# ---------------------------------
# CVE-2020-1472 Event Reader v1.0 8/4/2020
# This script will:
#    1. Scan system evtx in input file folder for event 5827, 5828,5829,5830 and 5831, exact data fields, export to 582#-*.CSV.
#    2. Calls Excel to import resulting 582#-*.CSV, create pivot tables for common secure RPC analysis scenarios. Delete 582#-*.CSV afterward. 
#   Feel free to modify to fit your need.
# ---------------------------------
# Script requires Excel 2013 or later.
#   64 bits Excel will allow creation of larger data import to XLS. 
# ---------------------------------
# To use the script:
#  1. Save system log as system.evtx to file.
#  2. Follow on screen prompt to enter Path containing *.evtx and final xlsx.
