LockdownBrowser专用远程软件(以下简称LDB)

使用过LDB的小伙伴应该都知道,这款软件禁用了大多数的社交通讯和远程控制软件,如:向日葵、ToDesk、RustDesk、WhatsApp、QQ、WeChat等。 在建立远程控制连接时,主流的远程控制软件通常会弹出提示窗口,而这些窗口极易被LDB检测到,从而触发屏幕截图并报告给学校。 如果网络环境不稳定,LDB也可能会检测到异常情况。

LDB还能够通过读取系统事件来检测是否有切屏、快捷键以及远程复制粘贴的行为。 LDB能够监控当前浏览器的活动窗口,如果发现用户切出考试页面,便会触发警告弹窗,视为异常操作。 同时,LDB还会检查系统剪切板,如果发现用户远程复制答案,则很可能会被标记为异常。 此外,LDB还升级了黑屏保护(DRM),学校的IT管理员可以轻松在每场考试中启用黑屏保护功能。 当一场考试发生多次异常时,LDB会向学校报告这些问题。 常见的远程控制软件要么被屏蔽,要么无法突破黑屏保护,导致无法获取考试界面。

为了方便学生在LDB环境下进行远程控制,我们团队特别开发了一款专用软件。 该软件采用了更加接近操作系统底层的方式来获取画面,并控制键盘和鼠标,能够完美避开LDB的检测机制。 我们的专业团队负责软件的安装和配置,并确保每一场考试顺利进行。

如果您有绕过LDB进行远程考试的需求,请联系我们,我们将为您提供专业的解决方案。

LockdownBrowser Dedicated Remote Software (hereafter referred to as LDB)

Anyone who has used LDB is likely aware that it disables most social communication and remote control software, such as AnyDesk, ToDesk, RustDesk, WhatsApp, QQ, WeChat, and others. When establishing a remote control connection, mainstream remote control software typically prompts a notification, which can easily be detected by LDB. This leads to a screenshot being captured and reported to the school. If the network environment is unstable, LDB may also detect anomalies.

LDB can detect system events, including screen switching, keyboard shortcuts, and remote copy-paste actions. It monitors the active window of the browser during the exam, and if it detects that the user has switched away from the exam page, it will trigger a warning popup and mark it as suspicious behavior. LDB also checks the system clipboard, and if it detects remote copying of answers, it will likely classify this as abnormal activity. Additionally, LDB has upgraded its black screen protection (DRM), which allows school IT administrators to easily enable black screen protection for each exam. If multiple anomalies occur during an exam, LDB will report these issues to the school. Common remote control software is either blocked or unable to bypass the black screen protection, making it impossible to access the exam interface.

To help students conduct remote control in the LDB environment, our team has developed a dedicated software solution. This software uses a method that is closer to the operating system's core to capture the screen and control the keyboard and mouse, effectively bypassing LDB's detection mechanisms. Our professional team handles the installation and configuration of the software, ensuring that each exam runs smoothly.

If you need assistance with bypassing LDB for remote exams, please contact us, and we will provide a professional solution tailored to your needs.

LockdownBrowser是如何检测常规远程控制行为的?

LockdownBrowser不仅可以屏蔽主流远程控制软件的使用,它能够通过多种技术手段间接识别这种作弊行为:

1. 行为模式异常检测

LockdownBrowser能够分析鼠标、键盘、屏幕活动和摄像头监控的行为,发现异常模式。远程控制通常会导致一些明显异常:

  • 不正常的键鼠操作:远程控制的鼠标动作可能不符合正常行为,如移动方式、速度或点击位置异常,系统可能标记为可疑。
  • 输入与视频不符:如果摄像头显示你没有操作键盘或鼠标,但屏幕上有输入操作,这种不一致会被标记为异常。

2. 摄像头和音频监控

LockdownBrowser会在考试期间启用摄像头和麦克风。如果你未操作键盘和鼠标,但远程操控者正在操作,系统会发现你与考试操作不一致的状态,可能触发警报。

  • 面部和身体动作不一致:如手未在键盘上、目光不在屏幕上,而电脑有操作,LockdownBrowser可判断为远程控制或作弊行为。
  • 背景声音异常:LockdownBrowser会捕捉周围声音,如你与远程操作者通话,这些声音可能被记录为潜在作弊证据。

3. IP地址和网络监控

LockdownBrowser会检测考试期间的IP地址和网络连接。如果远程控制工具通过不同IP地址连接,系统会发现以下异常:

  • IP地址变化:如果网络连接突然改变,可能触发警报。
  • 多设备检测:如果系统检测到考试通过不同设备进行(如通过远程控制连接),会识别出异常网络活动。

4. 软件使用检测

LockdownBrowser能够限制或监控某些应用的使用。如果你试图运行远程控制软件,如TeamViewer或AnyDesk,LockdownBrowser可能限制这些程序启动或检测其后台运行。

  • 禁止切换应用:LockdownBrowser可能阻止你切换到其他程序,如使用 Alt+Tab 切换到远程控制工具,系统会记录这种行为。
  • 系统行为异常:即使LockdownBrowser无法直接识别远程控制软件的名称,也能通过系统资源的使用情况或窗口行为检测到不正常的系统活动。

5. 考试后复查

LockdownBrowser会录制整个考试过程,供监考人员或管理员事后复查。即使未立即被发现,视频和屏幕录制可以揭示你未操作鼠标和键盘,而远程控制者在操作的情况,监考人员可以通过视频回放发现作弊行为。

How Does LockdownBrowser Detect Conventional Remote Control Behaviors?

LockdownBrowser can directly detect the use of remote control software, it can indirectly identify such cheating behaviors through various technical means:

1. Abnormal Behavior Pattern Detection

LockdownBrowser can analyze mouse, keyboard, screen activities, and camera-monitored behaviors to detect abnormal patterns. Remote control often leads to some obvious irregularities:

  • Unusual Mouse and Keyboard Operations: Remote-controlled mouse movements may not conform to normal behavior, such as abnormal movement patterns, speed, or click locations, and the system might flag this as suspicious.
  • Input Doesn’t Match Video: If the camera shows that you are not operating the keyboard or mouse, but there is input activity on the screen, this inconsistency will be marked as suspicious behavior.

2. Camera and Audio Monitoring

LockdownBrowser will enable the camera and microphone during the exam. If you are not operating the keyboard and mouse, but a remote operator is, the system will notice the discrepancy and might trigger an alert.

  • Inconsistent Facial and Body Movements: If your hands are not on the keyboard or your gaze is not on the screen while the computer is performing actions, LockdownBrowser can infer that remote control or cheating is taking place.
  • Unusual Background Sounds: LockdownBrowser can capture ambient sounds, and if you are speaking with a remote operator (e.g., via phone or voice software), these sounds may be recorded as potential cheating evidence.

3. IP Address and Network Monitoring

LockdownBrowser monitors the IP address and network connection during the exam. If remote control tools connect through different IP addresses, the system will detect the following abnormalities:

  • IP Address Change: If your network connection suddenly changes, it might trigger an alert.
  • Multiple Device Detection: If the system detects that the exam is being conducted on different devices (e.g., through remote control connections), it can identify this abnormal network activity.

4. Software Usage Detection

LockdownBrowser can limit or monitor the usage of certain applications. If you attempt to run remote control software such as TeamViewer or AnyDesk, LockdownBrowser may restrict these programs from launching or detect them running in the background.

  • Blocking Application Switching: LockdownBrowser may prevent you from switching to other programs, such as using Alt+Tab to switch to remote control tools, and the system will record this behavior.
  • Abnormal System Behavior: Even if LockdownBrowser cannot directly identify the specific name of remote control software, it can detect unusual system activity based on system resource usage or window behavior.

5. Post-Exam Review

LockdownBrowser records the entire exam process for invigilators or administrators to review afterward. Even if you were not immediately detected during the exam, the video and screen recordings may reveal situations where you did not operate the keyboard and mouse while a remote controller did. The invigilators can replay the video to find clues of remote control behavior.

一、软件功能

| 软件功能 | 高级版 | | ------------------------ |---------| | 键鼠操作 | 使用硬件API | | 软件捕获画面 | √ | | DRM破解 | √ | | 屏蔽主控方键鼠操作 | √ | | 屏蔽考试机键鼠操作 | √ | | 自动重连 | √ | | 快捷键 | √ |

注释:

  1. DRM破解:HL的黑屏保护,如果使用标准版发现进入考试界面时界面变黑,则说明本次考试启用了DRM保护。
  2. 快捷键:所有使用CTRL、ALT键的快捷键均支持,但不建议使用,因为HL有自己的快捷键检测逻辑。
  3. 屏蔽主控方键鼠操作:为了防止在巡考到来时写手仍在操控电脑从而被发现作弊行为,考试机支持屏蔽主控方的键鼠操作。注意,主控方有解除屏蔽的功能。
  4. 屏蔽考试机键鼠操作:支持屏蔽考试机是为了在考试时假装对简答题进行作答,而不影响远程控制。

二、定价规则(个人价格)

500元/小时,按考试全场收费,以小时为计价单元,最低一个小时

三、定价与退款规则(机构价格)

定价规则:

一场考试由以下几部分费用组成:

  1. 基础费用(Basic Price) 该部分费用可以理解为考试的起步价,是每一场考试都会收取的费用。
  2. 测试费用(Test Price) 该部分费用为测试时间的费用,每半个小时为一次计费单元,因此会按照每半个小时进行一次收费,不足半个小时的按半个小时收费,但会减免一个小时的费用。
  3. 考试费用(Exam Price) 该部分费用为考试时间的费用,每半个小时为一次计费单元,最低收费时间为一个小时(也就是考试时间单元数最低为2),之后每半个小时进行一次收费。
  4. 服务器的租赁费用(Server Price) 该部分费用用来租赁服务器,按天收费,不足一天的按一天计算。

总价 = 基础费用 + 距离考试的天数 * 服务器的租赁费用 + max(0,(测试时间单元数-2)) * 测试时间单价 + 考试时间单元数 * 考试时间单价。

特殊说明

  • 如果需要提前连接,可以在创建排期时将时间提前半个小时。若这半个小时没有进入考试页面,则这部分时间按测试时间计价(但不参与减免),具体扣费以服务器日志为准。

向后调整考试时间会再次收取服务器费用。这部分的定价公式为:

  1. 向后调整的秒数 = 目标时间 - 原来的考试时间
  2. 向后调整的天数 = 向上取整(向后调整的秒数/24/3600)
  3. 收取的费用 = 向后调整的天数 * Server Price

退款规则:

发生退款时,系统计算以下变量,并根据排期的不同状态来计算退款金额:

  • Server Cost:距离考试时间的剩余天数(向下取整,不足24小时按0计算) * Server Price。
  • Test Cost Full:max(0,(测试时间单元数-2)) * 测试时间单价。
  • Test Cost:减免的测试时间单元数 * 测试时间单价。
  • Exam Cost:max(2,考试时间单元数) * 考试时间单价
  1. 学生未确认或者学生拒绝排期: 退款金额 = Server Cost + Exam Cost + Test Cost Full + Basic Price。
  2. 学生确认排期,但在测试时间之前: 退款金额 = (Server Cost + Test Cost Full – Test Cost) * 0.5 + Exam Cost + Basic Price * 0.7。
  3. 在测试时间以后,但在考试时间之前: 退款金额 = (Server Cost + Exam Cost + Basic Price) * 0.3。
  4. 由于部分情况异常,退款金额可能无法正确计算,出现这种情况请及时联系我们
  5. 如果提前结束考试,需要手动关闭服务器(不允许再启动或重启服务器,否则会继续计费)后,联系我们说明具体场次考试已经提前结束。我们会审查服务器日志,并进行退款,未使用的考试时长退一半费用。比如预定了三个时间单元,但是只使用了两个时间单元,那么退款时第三个时间单元会退一半。
  6. 如果测试失败了,可以全额退款,这种情况需要联系我们。因为自动退款的逻辑不会全额退款。

四、适用平台

被控方:

  • Windows:
    • Windows 10:1607及以上版本
    • Windows 11:全平台支持

主控方:

  1. Mac OS:MacOS 11及以上(需要云电脑,此处为单独收费项)。
  2. Windows:Win10及以上。

五、其他说明与常见疑问

  1. 会被 LDB 检测到吗? 不会,本程序完全处于 LDB 的检测范围之外,且本程序使用的技术比 LDB 更复杂,操作权限在 LDB 之上,也不会破坏 LDB 程序的完整性。但值得注意的是:如果你的电脑上出现其他弹窗软件(例如鲁大师广告插件)导致的弹窗检测,本软件概不负责。

  2. 服务结束后,你们是否会随时控制我的电脑? 每个客户都分配了独立的服务器与账号密码,且仅在考试与测试期间可用,考试一旦完成,这些资源便会被销毁。我们不会尝试控制你的电脑
