使用 Autoruns 分析惡意軟體持續性

使用 Sysinternals Autoruns 系統性地列舉並分析 Windows 系統上的惡意軟體持續性機制。

使用 Autoruns 分析惡意軟體持續性 是什麼?

這個技能提供了一個結構化的工作流程,利用 Sysinternals Autoruns 全面掃描 Windows 系統上的自動啟動擴展點 (ASEP),涵蓋 18 個以上的類別,包括 Run/RunOnce 登錄機碼、服務、排程工作、驅動程式、Winlogon 項目、LSA 提供者、列印監視器、WMI 訂閱和 AppInit DLL。它整合了數位簽章驗證以過濾已簽署的 Microsoft 項目,並透過基線比對功能識別新新增的持續性機制。此外,該技能包含一個 Python 腳本,用於自動化掃描和可疑項目檢測,並根據未簽署的二進位檔案、可疑路徑和 LOLBin 啟動字串進行標記。支援 VirusTotal 整合以檢查雜湊信譽,並使用 -z 標誌進行離線分析以檢查鑑識磁碟映像。此技能適用於安全事件調查、威脅情資獵捕和 SOC 分析程序,並以 MITRE ATT&CK T1547 技術為參考。

使用 Autoruns 分析惡意軟體持續性 是做什麼的?

概述

Sysinternals Autoruns 從 Windows 上數百個自動啟動擴展點 (ASEP) 提取資料,掃描 18+ 個類別,包括 Run/RunOnce 機碼、服務、排程工作、驅動程式、Winlogon 項目、LSA 提供者、列印監視器、WMI 訂閱和 AppInit DLL。數位簽章驗證會過濾 Microsoft 簽署的項目。比較功能可透過基線差異分析識別新新增的持續性機制。VirusTotal 整合可檢查雜湊信譽。透過 -z 旗標支援離線分析,可進行鑑識磁碟映像檢查。

使用時機

  • 調查需要分析惡意軟體持續性的安全事件時
  • 為此領域建立偵測規則或威脅情資獵捕查詢時
  • SOC 分析師需要此分析類型的結構化程序時
  • 驗證相關攻擊技術的安全監控覆蓋範圍時

先決條件

  • Sysinternals Autoruns (GUI) 和 Autorunsc (CLI)
  • 目標系統的管理員權限
  • Python 3.9+ 用於自動化分析
  • 用於信譽檢查的 VirusTotal API 金鑰
  • 用於比較的乾淨基線匯出
