在涉及恶意软件的任何调查中,寻找持久性点(也称为“自动启动扩展点”或ASEP)是一项经常出现的任务。持久性点(Persistence Points)通常指的是计算机系统中一些可以被恶意软件利用来确保其在系统重启后仍能存活和运行的特定位置或机制。自动启动扩展点(ASEP,Automatic Startup Extension Points)
在涉及恶意软件的调查中,寻找持久性点(Persistence Points)
是一项非常重要的任务。这些持久性点也被称为自动启动扩展点(ASEP,Automatic Startup Extension Points)
,它们是恶意软件常用的一种技术,用来在系统启动时自动运行并确保恶意软件持续存在和活动。
恶意软件利用持久性点可以在受感染的计算机系统上实现自启动,使其能够在系统启动时自动加载并在后台运行,从而持续地进行恶意活动。因此,在进行恶意软件调查时,寻找和分析这些持久性点对于识别、清除和防范恶意软件至关重要。
常见的持久性点包括注册表项、启动文件夹、计划任务、系统服务等。调查人员通常会检查这些地方,以确定是否存在恶意软件植入的自动启动项。一旦发现持久性点与恶意软件有关,调查人员可以采取适当的措施来清除恶意软件并修复系统安全漏洞,以确保系统安全。
持久性点(Persistence Points)
通常指的是计算机系统中一些可以被恶意软件利用来确保其在系统重启后仍能存活和运行的特定位置或机制。恶意软件经常利用持久性点来实现自动启动、隐藏、和维持其活动的能力。以下是一些常见的持久性点:
-
注册表: 恶意软件可以修改注册表中的特定键值,使得自身在系统启动时被自动加载。例如,注册表的
Run
和RunOnce
键下的条目就是常被利用的自启动位置。 -
启动文件夹: 恶意软件可以将其可执行文件或快捷方式放置在系统的启动文件夹中,使得在用户登录后会自动执行。
-
服务: 恶意软件有时会注册成为系统服务,这样它可以在系统启动时自动运行并且在后台持续操作。
-
任务计划程序: 恶意软件可以创建任务计划程序,以便在特定时间或系统事件发生时自动执行其代码或脚本。
-
启动批处理脚本: 可以通过编写启动时执行的批处理脚本,使得恶意软件在系统启动时自动运行并执行特定的操作。
-
启动项: 操作系统或第三方软件可能会在系统启动时加载特定的启动项,这些项可以被恶意软件利用来实现自动启动和隐藏。
持久性点的存在使得恶意软件能够在系统重启后自动重现其活动,这对于其攻击能力和持续存在非常关键。因此,安全措施通常包括监控和审查这些持久性点,定期扫描系统以检测异常活动,以及使用反恶意软件工具来清除和阻止这些持久性点的利用。
自动启动扩展点(ASEP,Automatic Startup Extension Points)
是指操作系统或应用程序提供的一些机制或接口,允许软件在系统启动时自动执行特定的任务或加载特定的组件。这些扩展点通常被恶意软件利用来实现自启动和隐藏恶意活动的目的,因此在安全领域中,ASEP也成为一种关注的对象。
常见的自动启动扩展点包括:
-
注册表启动项: Windows系统中,通过修改注册表中的特定键值,可以指定程序在用户登录或系统启动时自动执行。恶意软件经常利用这些启动项来实现自启动,如注册表中的
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
和HKLM\Software\Microsoft\Windows\CurrentVersion\Run
。 -
启动文件夹: 操作系统允许用户将程序的快捷方式放置在特定的启动文件夹中,这样在用户登录时会自动执行这些程序。恶意软件可以将自己的快捷方式放置在这些文件夹中,以实现自启动。
-
服务: 操作系统和应用程序可能会作为服务在后台运行,服务可以在系统启动时自动启动并持续运行,提供特定的功能或服务。恶意软件有时会伪装成系统服务或利用服务的机制来实现自启动和隐藏。
-
启动批处理脚本: 通过操作系统的任务计划程序或类似的机制,可以在系统启动时自动运行批处理脚本。这些脚本可以执行各种操作,包括启动程序、修改系统设置等。
ASEP的合法使用包括系统管理、自动化部署和配置管理等,但在安全方面,重要的是及时监控和审查这些自动启动点,以防止恶意软件的利用和攻击。安全措施可以包括使用安全软件检测和清除恶意启动项、定期审查注册表和启动文件夹、限制用户权限以及实施白名单策略等。
理解和区分这些不同术语的含义可以帮助我们更好地掌握自动启动机制。让我们分别看看它们的具体含义和区别:
1. ASEP(Autoruns Entry Points)
Autoruns Entry Points 指的是系统中负责列出所有自动运行程序的入口点。Autoruns 是由 Sysinternals(现为微软的一部分)开发的一款工具,用于显示和管理 Windows 系统启动时自动运行的所有程序、服务和驱动。
- 功能:主要用于查看和管理所有已经配置为自动启动的项目,包括但不限于注册表项、启动文件夹、浏览器辅助对象等。
- 用途:系统管理员和安全专家常用此工具来检测和删除不必要或恶意的启动项。
2. ASEP (Auto-Start Extensibility Points)
Auto-Start Extensibility Points 是一种通用术语,指的是操作系统中允许程序在启动时自动运行的扩展点。这些扩展点可以存在于多个位置,例如:
- 注册表中的
Run
和RunOnce
键。 - 启动文件夹中的快捷方式。
- Windows 服务。
- 任务计划程序中的任务。
- 浏览器插件和扩展。
这个术语通常用于描述系统整体的自动启动机制,而不是特定的工具或方法。
3. ASEP(Automatic Startup Extension Points)
Automatic Startup Extension Points 实际上是对 Auto-Start Extensibility Points 的另一种描述方式。两者可以互换使用,都指的是操作系统中管理自动启动程序的机制和位置。
区别总结
- ASEP(Autoruns Entry Points):特指由 Autoruns 工具扫描和列出的自动启动程序条目,强调的是实际使用工具查看和管理这些条目。
- ASEP (Auto-Start Extensibility Points) 和 ASEP(Automatic Startup Extension Points):这两个术语指的是同一个概念,即操作系统中允许自动启动程序的机制和位置,没有本质区别,只是表达方式不同。
小结
- Autoruns Entry Points:具体指 Autoruns 工具显示的启动项。
- Auto-Start Extensibility Points 和 Automatic Startup Extension Points:指操作系统中管理自动启动程序的机制,两者可以互换使用。
理解这些术语的背景和用途有助于更好地管理和维护系统的启动过程,确保系统安全和性能优化。
ASEP(Auto-Start Extensibility Points)
和自动启动扩展点(Automatic Startup Extension Points
)实际上是同一个概念的不同翻译或表达方式。它们都指的是操作系统(特别是Windows)中的一种机制,用于管理和控制在系统启动时自动运行的程序和服务。
ASEP(Auto-Start Extensibility Points)
ASEP 是 Auto-Start Extensibility Points 的缩写,直接翻译过来就是“自动启动扩展点”。这是一种机制,允许应用程序在系统启动时自动运行。ASEP 可以存在于多个位置,包括但不限于:
- 注册表中的
Run
和RunOnce
键。 - 启动文件夹中的快捷方式。
- Windows 服务。
- 任务计划程序中的任务。
这类机制通常用于确保某些关键程序或服务在系统启动时立即可用,但也可能被恶意软件滥用,以在系统启动时自动运行。
自动启动扩展点(Automatic Startup Extension Points)
自动启动扩展点 是对 ASEP 的另一种描述方式。这种表达更直观地传达了其功能,即某些程序或服务通过这些扩展点设置为在系统启动时自动运行。
相同点
- 目的相同:无论是 ASEP 还是自动启动扩展点,目的是相同的——管理系统启动时自动运行的程序和服务。
- 机制一致:它们都涉及操作系统提供的多种自动启动机制,如注册表项、启动文件夹、Windows 服务和任务计划程序等。
细微区别
- 术语使用:ASEP 更像是一个技术术语或者缩写,常出现在技术文档和专业讨论中。而“自动启动扩展点”则是一种更口语化、描述性的叫法,可能更容易让普通用户理解。
- 表达方式:ASEP 强调的是一种技术实现和扩展性,而自动启动扩展点则更强调实际的启动行为。
小结
无论是 ASEP(Auto-Start Extensibility Points)还是自动启动扩展点(Automatic Startup Extension Points),本质上指的都是同一个概念,即操作系统中用于在启动时自动运行程序和服务的各类机制。不同的表达方式只是为了适应不同的受众或场景,但其核心内容和功能没有区别。

Explorer
The Explorer tab lists common autostart entries that hook directly into Windows Explorer3 and usually run in-process with Explorer.exe. Again, although most entries are systemwide, there are a number of per-user entries. Key entries on the Explorer tab include the following:
-
Shell extensions that add context menu items, modify property pages, and control column displays in folder windows
-
Namespace extensions such as the Desktop, Control Panel, and Recycle Bin, as well as third-party namespace extensions
-
Pluggable namespace handlers, which handle standard protocols such as http, ftp, and mailto, as well as Microsoft or third-party extensions such as about, mk, and res
-
Pluggable MIME filters
On 64-bit versions of Windows, in-process components such as DLLs can be loaded only into processes built for the same CPU architecture. For example, shell extensions implemented as 32-bit DLLs can be loaded only into the 32-bit version of Windows Explorer—and 64-bit Windows uses the 64-bit Explorer by default. Therefore, these extensions might not appear to work at all on 64-bit Windows.
The following lists the Explorer ASEP locations that Autoruns inspects on a particular instance of an x64 version of Windows 10.

Internet Explorer
Internet Explorer is designed for extensibility, with interfaces specifically exposed to enable Explorer bars such as the Favorites and History bars, toolbars, and custom menu items and toolbar buttons. And Browser Helper Objects (BHOs) enable almost limitless possibilities for extending the capabilities and user experiences for Internet Explorer.
However, because so much of users’ computer time is spent in a browser, and because much of the high-value information that users handle (such as passwords and credit card information) goes through the browser, it has become a primary target of attackers. The same programmatic interfaces that enable integration with third-party document readers and instant messaging have also been used by spyware, adware, and other malicious endeavors.
The following lists the Internet Explorer ASEP locations that Autoruns inspects on a particular instance of an x64 version of Windows 10.

Scheduled Tasks
The Scheduled Tasks tab displays entries that are configured to be launched by the Windows Task Scheduler. The Task Scheduler allows programs to be launched on a fixed schedule or upon triggering events, such as a user logging on or the computer being idle for a period of time. Commands scheduled with At.exe also appear in the list. The Task Scheduler was greatly enhanced in Windows Vista, so Windows now makes heavy use of it, and the list on the Scheduled Tasks tab will generally be long unless you hide verified Windows entries.
Because tasks can actually be disabled in Windows (unlike Start menu items), clearing the check box next to a scheduled task in Autoruns disables the task rather than copying it to a backup location.4
If you select Jump To Entry from the Entry menu for a scheduled task entry, Autoruns displays the Task Scheduler user interface, but it does not try to navigate to the selected entry.
Services
Windows services run in noninteractive, user-mode processes that can be configured to start independently of any user logging on, and that are controlled through a standard interface with the Service Control Manager. Multiple services can be configured to share a single process. A common example of this can be seen in Svchost.exe (Host Process for Windows Services), which is specifically designed to host multiple services implemented in separate DLLs.
Services are configured in the subkeys of HKLM\System\CurrentControlSet\Services. The Start value within each subkey determines whether and how the service starts.
Autoruns’ Services tab lists services that are not disabled, unless they were disabled by Autoruns (indicated by the presence of an AutorunsDisabled value in the service’s registry key). The content for the Description column comes from the text or the resource identified by the Description value in the configuration key. The image path column displays the path to the service executable; for Svchost services, Autoruns displays the path to the target DLL identified by the ServiceDll value in the service’s key or its Parameters subkey. There are cases for some services in some versions of Windows where administrative rights are required to view the Parameters key; in these cases, Autoruns displays the path to Svchost.exe in the image path column.
Be certain you know what you are doing when disabling or deleting services. Missteps can leave your system with degraded performance, unstable, or unbootable. And again, note that disabling or deleting a service does not stop the service if it is already running.
One malware technique to watch for is a service that looks like it’s supposed to be part of Windows but isn’t, such as a file named svchost.exe in the Windows directory instead of in System32. Another technique is to make legitimate services dependent on a malware service; removing or disabling the service without fixing the dependency can result in an unbootable system. Autoruns’ Jump To Entry feature is handy for verifying whether the service’s configuration in the registry includes a DependOnService value that you can inspect for dependencies before making changes.
Drivers
Like services, drivers are also configured in the subkeys of HKLM\System\CurrentControlSet\Services, as well as in HKLM\Software\Microsoft\Windows NT\CurrentVersion\Font Drivers. Unlike services, drivers run in kernel mode, thus becoming part of the core of the operating system. Most are installed in System32\Drivers and have a .sys file extension. Drivers enable Windows to interact with various types of hardware, including displays, storage, smartcard readers, and human input devices. They are also used to monitor network traffic and file I/O by antivirus software (and by Sysinternals utilities such as Procmon and Procexp!). And, of course, they are also used by malware, particularly rootkits.
As with services, the Drivers tab displays drivers that are not marked as disabled, except those disabled through Autoruns. The Description value comes from the version resource of the driver file, and the image path points to the location of the driver file.
Most blue-screen crashes are caused by an illegal operation performed in kernel mode, and most of those are caused by a bug in a third-party driver. (Less common reasons for blue screens are faulty hardware, the termination of a system-critical process such as Csrss.exe, or an intentional crash triggered through the keyboard driver’s crash functionality, as described in Knowledge Base article 244139: http://support.microsoft.com/kb/244139.)
You can disable or delete a problematic driver with Autoruns. Doing so will usually take effect after a reboot. As with services, be absolutely certain you know what you are doing when disabling or deleting the configuration of drivers. Many are critical to the operating system, and any misconfiguration might prevent Windows from working at all.
Codecs
The Codecs category lists executable code that can be loaded by media playback applications. Buggy or misconfigured codecs have been known to cause system slowdowns and other problems, and these ASEPs have also been abused by malware. The following lists the keys that are shown on the Codecs tab.

Boot Execute
The Boot Execute tab shows you Windows native-mode executables that are started by the Session Manager (Smss.exe) during system boot. BootExecute typically includes tasks, such as hard-drive verification and repair (Autochk.exe), that cannot be performed while Windows is running. The Execute, S0InitialCommand, and SetupExecute entries should never be populated after Windows has been installed. The following lists the keys that are displayed on the Boot Execute tab.

Image hijacks
Image hijacks is the term I use for ASEPs that run a different program from the one you specify and expect to be running. The Image Hijacks tab displays four types of these redirections:
-
exefile Changes to the association of the .exe or .cmd file types with an executable command. The file-association user interfaces in Windows have never exposed a way to change the association of the .exe or .cmd file types, but they can be changed in the registry. Note that there are per-user and systemwide versions of these ASEPs.
-
htmlfile Changes to the association of the .htm or .html file types with an executable command. Some malware that hijacks these ASEPs can come into play when you open an HTML file. Verify that the executable command is a legitimate browser.
-
Command Processor\Autorun A command line that is executed whenever a new Cmd.exe instance is launched. The command runs within the context of the new Cmd.exe instance. There is a per-user and systemwide variant, as well as a separate version for the 32-bit Cmd.exe on 64-bit Windows.
-
Image File Execution Options (IFEO) Subkeys of this registry location (and its echo in the 64-bit versions of Windows) are used for a number of internal and undocumented purposes. One purpose for IFEO subkeys that has been documented is the ability to specify an alternate program to start whenever a particular application is launched. By creating a subkey named for the file name of the original program and a “Debugger” value within that key that specifies an executable path to an alternate program, the alternate program is started instead and receives the original program path and command line on its command line. The original purpose of this mechanism was for the alternate program to be a debugger and for the new process to be started by that debugger, rather than having a debugger attach to the process later, after its startup code had already run. However, there is no requirement that the alternate program actually be a debugger, nor that it even look at the command line passed to it. In fact, this mechanism is how Process Explorer (described in Chapter 3) replaces Task Manager.
The following list shows the registry keys corresponding to these ASEPS that are shown on the Image Hijacks tab.

AppInit
The idea behind AppInit DLLs surely seemed like a good idea to the software engineers who incorporated it into Windows NT 3.1. Specify one or more DLLs in the Appinit_Dlls registry key, and those DLLs will be loaded into every process that loads User32.dll (that is, virtually all user-mode Windows processes). Well, what could go wrong with that?
-
The AppInit DLLs are loaded into the process during User32’s initialization—that is, while its DllMain function is executing. Developers are explicitly told not to load other DLLs within a DllMain. It can lead to deadlocks and out-of-order loads, which can lead to application crashes. And yet here, the AppInit DLL “feature” does exactly that. And yes, that has led to deadlock and application crashes.5
-
A DLL that automatically gets loaded into every process on the computer sounds like a winner if you are writing malware. Although AppInit has been used in legitimate (but misguided) software, it is frequently used by malware.
Because of these problems, AppInit DLLs are deprecated and disabled by default in Windows Vista and newer. For purposes of backward compatibility, it is possible to re-enable AppInit DLL functionality, but doing so is strongly discouraged. To ensure that AppInit DLLs have not been re-enabled, verify that the LoadAppInit_DLLs DWORD value is 0 in HKLM\Software\Microsoft\Windows NT\CurrentVersion\Windows and in HKLM\Software\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows.

HKLM\Software\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows\Appinit_Dlls
HKLM\System\CurrentControlSet\Control\Session Manager\AppCertDlls
KnownDLLs
KnownDLLs helps improve system performance by ensuring that all Windows processes use the same version of certain DLLs, rather than choose their own from various file locations. During startup, the Session Manager maps the DLLs listed in HKLM\System\CurrentControlSet\Control\Session Manager\KnownDlls into memory as named section objects. When a new process is loaded and needs to map these DLLs, it uses the existing sections rather than searching the file system for another version of the DLL.
The Autoruns KnownDLLs tab should contain only verifiable Windows DLLs. On 64-bit versions of Windows, the KnownDLLs tab lists one ASEP, but file entries are duplicated for both 32-bit and 64-bit versions of the DLLs, in directories specified by the DllDirectory and DllDirectory32 values in the registry key. Note that the Windows-On-Windows-64 (WOW64) support DLLs are present only in the System32 directory and Autoruns will report “file not found” for the corresponding SysWOW64 directory entries. This is normal.
To verify that malware hasn’t deleted an entry from this key so that it can load its own version of a system DLL, save the Autoruns results from the suspect system and compare it against the results from a known-good instance of the same operating system. See the “Saving and comparing results” section later in this chapter for more information.
Winlogon
The Winlogon tab displays entries that hook into Winlogon.exe, which manages the Windows interactive-logon user interface. Introduced in Windows Vista, the Credential Provider interface manages the user authentication interface. Today, Windows includes many credential providers that handle password, PIN, picture-password, smartcard, and biometric logon. Most of these are shown only if you disable the Hide Windows Entry option. Third parties can supply credential providers that further customize interactive user logons.
The Winlogon tab also includes the user’s configured screen saver, which is started by Winlogon.exe after inactivity, and registered Group Policy client-side extensions (CSEs), which are DLLs that the Group Policy engine loads. The Group Policy engine used to run in the Winlogon process, but now it runs in the Group Policy Client service.
The following list specifies the registry keys that are shown on the Winlogon tab.

Winsock providers
Windows Sockets (Winsock) is an extensible API on Windows because third parties can add a transport service provider that interfaces Winsock with other protocols or layers on top of existing protocols to provide functionality such as proxying. Third parties can also add a namespace service provider to augment Winsock’s name-resolution facilities. Service providers plug into Winsock by using the Winsock service provider interface (SPI). When a transport service provider is registered with Winsock, Winsock uses the transport service provider to implement socket functions, such as connect and accept, for the address types that the provider indicates it implements. There are no restrictions on how the transport service provider implements the functions, but the implementation usually involves communicating with a transport driver in kernel mode.
The Winsock tab lists the providers registered on the system, including those that are built into Windows. You can hide the latter group by enabling Hide Windows Entries and Verify Code Signatures to focus on the entries that are more likely to be causing problems.

HKLM\System\CurrentControlSet\Services\WinSock2\Parameters\Protocol_Catalog9\Catalog_Entries64
Print monitors
The entries listed on the Print Monitors tab are DLLs that are configured in the subkeys of HKLM\System\CurrentControlSet\Control\Print\Monitors. These DLLs are loaded into the Spooler service, which runs as Local System.
LSA providers
This category of autostarts comprises packages that define or extend user authentication for Windows, via the Local Security Authority (LSA). Unless you have installed third-party authentication packages or password filters, this list should contain only Windows-verifiable entries. The DLLs listed in these entries are loaded by Lsass.exe or Winlogon.exe and run as Local System.
The SecurityProviders ASEP that is also shown on this tab lists registered cryptographic providers. DLLs listed in this ASEP get loaded into many privileged and standard user processes, so this ASEP has been targeted as a malware persistence vector. (This ASEP isn’t truly related to the LSA, except that, like the LSA, it represents security-related functionality.)

HKLM\System\CurrentControlSet\Control\Lsa\OSConfig\Security Packages
Keys inspected for Registered Cryptographic Providers
HKLM\System\CurrentControlSet\Control\SecurityProviders\SecurityProviders
Network providers
The Network Providers tab lists the installed providers handling network communication, which are configured in HKLM\System\CurrentControlSet\Control\NetworkProvider\Order. On a Windows desktop operating system, for example, this tab includes the default providers that provide access to SMB (file and print) servers, Microsoft RDP (Terminal Services/Remote Desktop) servers, and access to WebDAV servers. Additional providers are often visible in this list if you have a more heterogeneous network or additional types of servers that Windows needs to connect to. All entries in this list should be verifiable.
WMI
The WMI tab lists registered WMI event consumers that can be configured to run arbitrary scripts or command lines when a particular event occurs. When you select an entry on the WMI tab, the lower panel reports information about the target file, the event consumer’s full command line, and the condition, such as a WQL query, that will trigger the event consumer to execute.
When you disable a WMI entry, Autoruns replaces the entry with a clone that has the same name but with “_disabled” appended. This breaks the binding to the event filter so that it won’t execute. By re-enabling, the original name and the event binding is reestablished.
These events and bindings are stored in the WMI repository in the ROOT\subscription namespace.
Sidebar gadgets
On Windows Vista and Windows 7, this tab lists the Sidebar Gadgets (called “Desktop Gadgets” on Windows 7) that are configured to appear on the user’s desktop. Although gadget software is often (but not always) installed in a systemwide location such as %ProgramFiles%, the configuration of which gadgets to run is in %LOCALAPPDATA%\Microsoft\Windows Sidebar\Settings.ini, which is per-user and nonroaming. Disabling or deleting gadgets with Autoruns manipulates entries in the Settings.ini file.
The image path usually points to an XML file. The gadgets that shipped with Windows Vista and Windows 7 are catalog signed and can be verified. Gadgets were discontinued after Windows 7.
Office
The Office tab lists add-ins and plug-ins registered to hook into documented interfaces for Access, Excel, Outlook, PowerPoint, and Word. On 64-bit Windows, Office add-ins can be registered to run in 32-bit or 64-bit Office versions. 32-bit add-ins are registered in Wow6432Node subkeys on 64-bit Windows.
