Re: Safe Exam Browser Jailbreak
Marika Szala
SEB locks everything by taking control of the whole U.I and there is nothing you can do there. We can modify the opensource seb code but the signature of the code will be invalidated and you cannot enter the exam.
As I told you that changing User-Agent and X-SafeExamBrowser-RequestHash will allow you to write the exam in the same browser. But it will not work with MOODLE and ILIAS Lms has they have the capability to implement browser-exam-key security.Anyways Bypassing the VM detection will do the trick.
Exam.net has more liberal security integration with a safe exam browser. It provides the .seb config file to the browser and triggers the SEB to load the configuration and then it totally depends on the SEB security protocols and verify neither the integrity of the SEB code nor the Configuration file integrity.
However, SEB allowed me to install VMware tools but when starting the exam inside the SEB, Exam.net blocked me by saying you cannot use this device.It is due to the fact the presence of VMware Tools. So, As mentioned above do not install VMware tools.
There is another way to get past the VMware tools installation is by selecting Launch Take a Test (WIN10) which will allow you to get past the VMwaretools restriction and Virtual Machine Detection as it is not SEB (Take a Test is a Microsoft product).
We want to use proctoring based on WebRTC, and it looks like this should work with Windows SEB, however there appears to be no support on MacOS? It has worked in safari for a couple of versions now, so as far as I can see there is no technical reason it should not work. Perhaps SEB just needs handlers to request the device permissions for webcam and microphone? As I am sure you are aware with Covid-19 proctoring remote exams has become a priority for all of us, however restricting students to Windows machines is not going to work. We really need support for Windows, Mac OSX. iOS support would be the next priority after those two,
I'm sorry to say that, but you are not fully informed. There is a technical reason why WebRTC doesn't work in SEB: Apple doesn't support it in WKWebView, only in Safari. The same applies to Service Workers for example. Just do an Internet search if you don't believe me, I also mentioned this in various other threads in this forum.
Apple seems to be concerned about privacy and security, and therefore don't support it in embeded web views. They received numerous feature request for these and other features to be supported in WKWebView, but I would suggest you also file some at I also spoke to my Apple contacts about it, I hope they may reconcider that. But even if they do and add it in the next macOS and iOS versions, older versions still wouldn't support it.
Ok, the support for "home screen web app" in iOS 13.4 doesn't solve the issue for SEB, as it's still no supported in WKWebView. But other posts there seem to suggest that Apple wants to support it in WKWebView as well.
This uses a "private" API, but seeing as there is no reason not to use a private API on the Mac (note this is not iOS), becuse you don't distribute Mac applications through the app store. Note: the objective-c version works, they are asking for help because it doesn't work in Swift.
I think you missinterpreted the comment. It's not a Swift problem, the issue is that the WKWebView doesn't get the permission to access the camera. That guy mentions that the private delegate methods for granting that access are not called, I don't think this has anything to do with Swift vs. Obj-c. I'm quite sure Apple secured the camera and microphone access in embedded web views well, probably using a private entitlement. Those are apparently enforced using kernel extensions, so you would need a major hack (Jailbreak on iOS) to circumvent that. On macOS maybe building WebKit yourself from the open source code could work, I might look into that later in Fall, when I integrated WKWebView itself.
Thanks for researching this, that will be helpful for macOS. As you can see in our roadmap, support for WKWebView in SEB for macOS and iOS is planned for Q3/2020. I currently expect that we can release that version in August. I will then include this fix for the non-App Store version of SEB for macOS.
I will do a build from Git without the fix to confirm it does not work, and then with the fix to confirm it works. If it does, why not just update the release version from the build? Presumably there is a git-tag for the current released versions of SEB Mac?
SEB for macOS and iOS are not yet using WKWebView, so it's not possible to just add these properties. Why we are not yet using WKWebView I explained in other threads numerous times. The lacking feature set of WKWebView requires massive changes in SEB, and we still have limited resources, so this takes time.
I started migrating to WKWebView in a side-project, but have to wait to do it in SEB and finish some other urgent updates first (SEB 2.2 for Mac with the new AAC kiosk mode and mainly the joint code-base for macOS and iOS, so I don't need to do the WKWebView stuff separately for both platforms). Nevertheless I hope to have the WKWebView version ready in early Q4. The basic stuff isn't complicated, but for SEB I need to port the URL filter to the built-in API in WKWebView and I need to implement a replacement for the Browser Exam / Config Key hash transmission in request heards, as you still cannot modify all HTTP requests in WKWebView.
I'm quite sure that guy in the webkit.org thread didn't actually succeeded to make it work, read his comment again thoroughly. Also no one answered "wow it works", people continue to discuss the issue and Apple's inaction about it...
Currently, the SEB procotoring features can be controlled with regular SEB settings (by reconfiguring SEB per session) or dynamically by the SEB Server (using a REST web service interface, see -server, not all documentation is publicly available yet, as some features are still in development).
When transitioning to WKWebView, we will finally need a JavaScript API in SEB (so in SEB 3.0 for macOS/iOS). After the basic functionallity, we will also add methods to that API for controlling various SEB features including the remote proctoring features. But don't expect that before Q1 or Q2 next year.
Currently these features are available in beta versions of SEB for iOS and developer versions of SEB Server. Remote proctoring with SEB is still in development, we will communicate availability in SEB versions for macOS and Windows at a later moment.
We're currently evaluating implementation for macOS and Windows. On macOS probably a native integration could be possible, on Windows we might use a web based approach running in the chromium browser engine.

Understanding how this proctoring exam browser is used in various pedagogical contexts helps get a feel for its inner workings and capabilities. There are now two widely used platforms for online education: Canvas and Blackboard.
Both students and teachers utilize the Respondus lockdown browser. Exams are administered and completed in the lockdown browser, which is used both by teachers and students. There are a few simple steps professors can take to integrate the Respondus Lockdown browser into Canvas:
To cheat on the lockdown browser, you need a virtual machine. A virtual machine is a software program that creates a virtual computer environment on your computer. You can use this environment to run another or multiple operating systems at once.
The Desktops.exe is a file that gives the user access to the desktop of another computer. A user can use this program to run applications on a remote computer and view its desktop. This feature helps in accessing your files while you are on lockdown browser.
Yes, it does. It also stores information from the cameras and microphones. Respondus Monitor will automatically record both video and sound. Any online tests that need the Respondus LockDown Browser software will be communicated to you by your instructor.
Impersonation occurs when a student recruits someone to take an examination on their behalf. Students give their login information to the imposter in advance of the exams. Depending on the program, you may need different credentials to log in.
This can be using sticky notes, using your palms to take notes, or even communicating with other students using sign language. Online proctored exams are vulnerable to these strategies, but remote proctoring can detect and prevent them.
As you use the Respondus LockDown Browser, it will track your eye movements. Before beginning the exam or test session, students must have their camera set up so that it captures their entire face, eyes and all.
The Activity Dashboard provides a detailed overview of all browsing activity performed by each user account on your PC. You can see which sites were visited, when they were visited, how long they were visited, and more detailed statistics about each site.
Learning management systems (LMS) is a software application that supports education delivery to students and employees. LMSes facilitate the administration of training programs, track student progress, and report results.
