Script para ajudar no monitoramento de IDs de eventos relacionados a alterações em conexões de canal seguro de Netlogon associadas à CVE-2020-1472

Resumo

O script disponível neste artigo é um complemento para as informações sobre como gerenciar as alterações nas conexões de canal seguro de Netlogon associadas à CVE-2020-1472. Ele é fornecido no seu exemplo.

O script processará arquivos EVTX exportados do Visualizador de eventos e criará uma planilha do Microsoft Excel contendo tabelas dinâmicas para os vários problemas e os dispositivos em seu ambiente que disparam os eventos. O script exige o PowerShell e o Microsoft Excel 2013 ou posterior (64 bits recomendados para conjuntos de dados maiores).

Uso

Será preciso exportar os EVTX arquivos dos DCS (controladores de domínio) que você está monitorando para as questões descritas no KB4557222. Para fazer isso, abra o Visualizador de eventos selecionando Iniciar, digite o Visualizador de eventos e selecione-o. Quando o Visualizador de eventos abrir, expanda logs do Windows, clique com o botão direito do mouse ou, em seguida, pressione a tecla e selecione salvar todos os eventos como... e salve o arquivo em um local para permitir o processamento do arquivo.

Se desejar, o script poderá processar mais de um EVTX arquivo por vez. O script pode levar muito tempo para ser concluído em grandes conjuntos de dados. Também é recomendável que você tenha os EVTX arquivos locais no mesmo dispositivo executando o script para ajudar a acelerar o processamento dos arquivos.

Será necessário executar o script em um aviso de comando do PowerShell. Não é necessário executar como administrador. O script será executado por meio de solicitações que você poderá atender conforme o necessário, a menos que você tenha definido o $mcScriptPrompts$false . Se os EVTX arquivos estiverem na mesma pasta que o script, não será necessário fornecer um caminho para eles.

Personalizar o script

Varia

Descrição

$mcScriptPrompts

Os $true,$false

Descritivo O valor padrão é $true o e exigirá a entrada/interação do usuário. O pode ser definido como $false se os EVTX arquivos estiverem na mesma pasta que o script e todas as outras configurações serão executadas como padrão.

$mcMaxExport

Valor padrão: 50000

Descritivo Com as configurações padrão, o script deixará de processar cada EVTX arquivo após a exportação de eventos 50000 para CSV arquivos. Se você estiver recebendo erros relacionados à memória do Microsoft Excel, precisará reduzir esse número ou ajustar quais dados estão sendo processadas, como alterar o $mcStartTime .

$mcMaxImport

Valor padrão: 50000

Descritivo Com as configurações padrão, o script deixará de processar os eventos após o arquivo CSV atual que está processando quando chegar ao número máximo de eventos 50000. Isso significa que, quando chegar ao número máximo de eventos, ele concluirá o CSV arquivo atual iniciado, mas não começará a processar um novo CSV arquivo.

$mcStartTime

Valor padrão: '2020/05/26 11:06'

Descritivo Essa variável permite que você defina uma hora de início e o script só processará eventos após essa data e hora. Se você já tiver abordado dispositivos até um determinado ponto, isso permite direcionar somente os eventos que você ainda não tratou.

$mcMaxThreads

Valor padrão: 4

Descritivo Essa variável permite aumentar ou diminuir o número de segmentos usados durante a importação dos eventos dos EVXT arquivos para CSV arquivos.

 

Dos

Abaixo você encontrará o script do PowerShell que você pode usar após a personalização para o seu ambiente. Será preciso copiar e colar esse script em um CVE-2020-1472EventReader.ps1 arquivo no dispositivo que você está usando para processar os eventos.

# ---------------------------------
# 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.
