Command Line Parameters

Clipboard Commands

A user typically carries out clipboard operations by choosing commands from an application’s Edit menu. Following is a brief description of the standard clipboard commands.

Cut Places a copy of the current selection on the clipboard and deletes the selection from the document. The previous content of the clipboard is destroyed. Copy Places a copy of the current selection on the clipboard. The document remains unchanged. The previous content of the clipboard is destroyed. Paste Replaces the current selection with the content of the clipboard. The content of the clipboard is not changed.

Standard Clipboard Formats

The clipboard formats defined by the system are called standard clipboard formats. These clipboard formats are described in the following table.

Text Text format. Each line ends with a carriage return/linefeed (CR-LF) combination. A null character signals the end of the data. Use this format for ANSI text.
Unicode Text Format Unicode text format. Each line ends with a carriage return/linefeed (CR-LF) combination. A null character signals the end of the data.
Rich Text Format Rich Text Format RTF.
HTML Format HyperText Markup Language Format. HTML is entirely text format (to be, among other things, in the HTML spirit, and uses UTF-8) and includes a description, an optional context, and, within the context, the fragment.
OEM Text Text format containing characters in the OEM character set. Each line ends with a carriage return/linefeed (CR-LF) combination. A null character signals the end of the data.
Locale Identifier The data is a handle to the locale identifier associated with text in the clipboard. When you close the clipboard, if it contains CF_TEXT data but no CF_LOCALE data, the system automatically sets the CF_LOCALE format to the current input language.
Bitmap A handle to a bitmap (HBITMAP).
Enhanced Metafile A handle to an enhanced metafile (HENHMETAFILE).
Metafile Picture Format Handle to a metafile picture format as defined by the METAFILEPICT structure.

The following guide provides you with three methods to clear the Windows Clipboard from content that it holds at the time.

Microsoft has not improved the clipboard functionality of its Windows operating system in a long time. Even the Windows 10 version allows you to only hold one entry in the Clipboard at all times. When you copy something new, the old is no longer available.

That’s probably the main reason why third-party clipboard managers such as Clipboard Help+Spell or Clipboard Master are popular programs. These programs allow you to keep a record of previous items copied to the clipboard, and may introduce additional functionality such as spell checking, item manipulation, or fast access to the previous ten or so entries.

Methods to clear the Windows Clipboard

The following methods provide you with options to clear the Windows Clipboard so that the stored entry is no longer available.

While there are not that many situations where you might want to clear the clipboard, some that come to mind are to avoid pasting data accidentally, avoid that software may record what is stored in the clipboard, or block others with access to the PC from checking it out.

Method 1: using the command line

How secure is the windows clipboard

One of the easier options. Simply run echo off | clip from the command line to clear the Windows Clipboard.

  1. Tap on the Windows-key, type cmd.exe, and hit the Enter-key. You may speed this up by pinning a link to the Windows command prompt to the taskbar, desktop or start menu.
  2. Type echo of |clip and hit the Enter-key.

The clipboard is now empty. You can speed things up further by creating a batch file and pinning it to a location you have access to quickly.

Method 2: Overwriting the content

If it is just about getting rid of whatever information is stored in the clipboard, you may simply copy something else into it to overwrite the previous entry.

To do so select a word, letter or even a blank space and hit Ctrl-C to copy it to the clipboard. Simple but faster than the command line option listed above.

Method 3: Using ClipTTL

ClipTTL is a free simple program for Windows that automates the process. The program wipes the clipboard in 20 second intervals.

All you need to do is run it to make use of its functionality. While it is certainly more comfortable than using the other methods, it may overwrite content too early or not quickly enough due to the 20 second interval that it uses.

Now You: Have another method not listed here? Let us know in the comment section below.

Synchronize clipboard between
all your devices!

— Copy on your computer, paste on your Android.
— Copy on your Android, paste on your computer.
— Copy on your phone, paste on your tablet.

— What is Clipbrd?

Clipbrd is a service that instantly, transparently and securely synchronizes the text you copy into a clipboard across all your devices.

— Which platforms are supported?

  • Any computer that runs Google Chrome (Linux, OS X, Windows)
  • Android 2.3+
  • Not supported yet: iOS

— Why would I want to use Clipbrd?

Here are some use cases:

1. Copying website URLs, so you don’t have to type them on touchscreen keyboard.
2. Copying one-time passwords (e.g. from Google Authenticator), so you don’t have to manually type them on your computer while looking at your phone.
3. Copying long text messages that you’ve typed on your computer to send them from your phone.

But generally, our service is designed to be as flexible as the idea of clipboard itself. We can’t wait to hear all the exciting ways that you’ll find Clipbrd useful!

— How does Clipbrd work?

You select a piece of text on your computer, copy it with Ctrl-C / Cmd-C or via context menu, then paste it on your phone/tablet using long tap on any input field.

You can do the other way around, too – copy some text on your phone or tablet, then paste it on your computer.

Actually, just copy on any device and paste on any other device 🙂

— Okay, but technically – how does it work?

Clipbrd runs in background, constantly monitoring your operating system clipboard for changes.

As soon as a change is detected, the content of the clipboard is encrypted and broadcasted to your other devices via our server.

Each device receives a copy of the clipboard, decrypts it and saves into operating system clipboard, so you could paste it from there.

— Does Clipbrd affect battery life of my phone/tablet?

No, you should not see any noticeable decrease in battery life.

Clipbrd is active only when you’re actually using your device. When the screen is off, Clipbrd goes to sleep.

— Are photos/music/other files supported?

No, not at the moment.

Our top priority is to achieve the best user experience when working with small text snippets.

There’s a lot of other great services that allow you to sync your photos, music and documents between your devices, e.g. Dropbox or Google Drive.

— Can I use Clipbrd outside of Google Chrome?

Clipbrd is a Google Chrome app, but it not limited to only working inside the Chrome window.

By default, Clipbrd will be running as a background app on your computer as long as Chrome itself is running.

— Isn’t it an awful idea to send all my clipboards over the Internet?!

It’s not as bad as it sounds 🙂

First, your clipboards are safely encrypted (with AES-256) on your device using your password (via PBKDF2).

So there’s no way for anyone (including NSA or even the Clipbrd staff) to see the contents of your clipboards while they are being synchronized.

Second, currently we only send the first 1000 characters of your clipboard content, so it won’t generate huge traffic.

According to HTTP Archive, the average Internet page size is 1411 kB (April 2013).

That means that visiting a single average web page generates almost the same amount of traffic as copying huge chunks of text into your clipboard every two seconds for an hour.

For those reasons, you probably shouldn’t worry about it.

— Do you store clipboards on your servers?

Currently we do not store clipboards – we only transmit them from one of your devices to the rest of your devices.

However, this will likely change in future.

If one of your devices is offline at the moment of the sync, it won’t receive the latest clipboard – even if the device was offline for just a moment.

For your convenience, in upcoming versions we’re going to store the latest version of the clipboard for delayed synchronization. Encrypted, as usual.

— Will you open source Clipbrd?

We’ll most definitely open source client applications in the near future, becase we understand the security implications of using Clipbrd.

For now, you can inspect the code of our Chrome app – it’s not minified/obfuscated in any way, so you can relatively easily verify that our crypto stuff actually works 🙂

Can anyone explain (or provide a link to a simple explanation) of what the Windows “Secure Desktop” mode is and how it works?

I just heard about it in the KeePass documentation (KeePass – Enter Master Key on a Secure Desktop) and would like to understand it better.

3 Answers 3

Short answer

There are three, separate issues claiming the name of “Secure Desktop”:

  • Windows builtin functions like GINA and the Credential Provider Model.
  • Separation of privileged vs unprivileged applications running as the same user (nominally prevent privilege escalation), which may or may not be related to:
  • SwitchDesktop() , which is what KeePass is using and may or may not (I’m not sure) be resistant to DLL Injection.

Detailed answer

As a quick primer to how Windows GUIs are built, basically everything runs through a function called CreateWindow() (I mean everything, every button, every menu, everything) and is given a hWnd or Window Handle. Modifying these Windows is done via another function, SendMessage() .

Here’s the catch. As a user mode application, making the right API calls I can fairly easily send messages to other Windows. It’s fairly trivial to make buttons disappear from other people’s forms. It is a little harder to perform DLL injection and hook the message loop that receives messages (the OS sends Windows messages when things happen to them) but not that much harder. If I can hook those events, I could automatically submit your “yes/no” form. Or, I could change the label from ReallyDodgyVirus.exe to explorer.exe and you’d be none the wiser.

Insert: A really good article on the various techniques of getting your code into the address space of a running process.

Now, what are KeePass doing?

A very brief perusal of the source shows they are using CreateDesktop() , SwitchDesktop() and CloseDesktop() to create a second desktop connected to the physical viewing device you’re on. In English, they’re asking the kernel to create for them an isolated desktop whose hWnd objects are outside of the findable range of any other application’s SendMessage() .

I should point out that SwitchDesktop suspends the updating of the UI of the default desktop. I’m not sure if the message loops are also frozen – I suspect not since the desktop is created as a new thread.

In this instance, KeePass is drawing the UI, so the execution is not, as I understand it, as NT AUTHORITY/SYSTEM . Instead, the new desktop is created in isolation from basically the rest of the current desktop, which protects it. I’ll be happy to be corrected on that. However, see the MSDN for SwitchDesktop:

The SwitchDesktop function fails if the desktop belongs to an invisible window station. SwitchDesktop also fails when called from a process that is associated with a secured desktop such as the WinLogon and ScreenSaver desktops. Processes that are associated with a secured desktop include custom UserInit processes. Such calls typically fail with an “access denied” error.

I believe this means that these dialogs (screensavers, Windows Logon) are built more deeply into Windows such that they always execute as NT AUTHORITY\SYSTEM and the UserInit process creates the sub processes on valid authentication at the required privilege level.

The reason I bring this up is because I believe there are two issues: different desktops and privilege separation. From Mark Russinovich’s discussion of the topic of Secure Desktop:

The Windows Integrity Mechanism and UIPI were designed to create a protective barrier around elevated applications. One of its original goals was to prevent software developers from taking shortcuts and leveraging already-elevated applications to accomplish administrative tasks. An application running with standard user rights cannot send synthetic mouse or keyboard inputs into an elevated application to make it do its bidding or inject code into an elevated application to perform administrative operations.

As SteveS says, UAC runs a separate desktop process as NT AUTHORITY/SYSTEM . If you can catch UAC in action ( consent.exe ) via process explorer, it looks like this:

Escalating privileges as a process I don’t have the specifics of, but here is what I think I understand: I believe the process of privilege escalation in the Windows API causes a process running as NT AUTHORITY/SYSTEM (therefore able to execute the new process under whatever privileges it wants to, in this case an Administrator). When an application asks for higher privileges, that question is asked to you on a new desktop locally, to which none of your applications can get either the Desktop Handle or any of the GUI element handles. When you consent, consent.exe creates the process as the privileged user. Thus, the process running as NT AUTHORITY\SYSTEM is a consequence of the need to create a new privileged process, not as a method of creating a secure desktop. The fact the desktop is different to the default is what adds security in both cases.

I believe what Mark means above is that, in addition to these secure desktops, two things are happening:

  • Your default administrator desktop is in fact running unprivileged, contrary to Windows XP and earlier and
  • Unprivileged and privileged applications now exist on separate desktops (disclaimer: could just be ACLs on the objects in memory, I’m not sure), ensuring that unprivileged code can’t access privileged objects.

The Windows Logon UI is different again in Vista/7.

Clearly, none of these methods will defend you against kernel mode rootkits, but they do prevent privilege escalation and UI integrity compromise by isolating privileged applications, or in the case of KeePass, the sensitive dialog.

Edit

Having looked harder at the KeePass code, I saw this handy piece of C#:

From this you can see that in fact in order to mimic consent.exe, KeePass takes a screenshot of the background, dims it and creates its new desktop with the background of the old desktop. I therefore suspect the old desktop continues running even while it isn’t being rendered. This I think confirms that no magic NT AUTHORITY\SYSTEM action is happening both with KeePass and consent.exe (I suspect consent.exe is doing the same thing UI-wise, it just happens to be launched in the context of NT AUTHORITY\SYSTEM ).

Edit 2

When I say DLL Injection, I’m specifically thinking of DLL injection to corrupt the UI. DLL Injection remains possible on KeePass as a process, I’m just not sure whether it could be used to influence that secure UI. It could, however, be used to access the memory of the process and its threads, thereby grabbing the entered password pre-encryption. Hard, but I think possible. I’d appreciate someone advising on this if they know.

Feature flag

This article discusses feature flag management and the various Citrix Workspace apps that support feature flags.

Feature flag management

If an issue occurs with Citrix Workspace app in production, we can disable an affected feature dynamically in Citrix Workspace app even after the feature is shipped. To do so, we use feature flags and a third-party service called LaunchDarkly. You do not need to make any configurations to enable traffic to LaunchDarkly, except when you have a firewall or proxy blocking outbound traffic. In that case, you enable traffic to LaunchDarkly via specific URLs or IP addresses, depending on your policy requirements.

The following table calls out the various apps that support feature flags and the release versions in which feature flags were introduced in these apps.

App Feature flag support Version Documentation
Citrix Workspace app for Android Yes 10.7.5 Feature flag management for Citrix Workspace app for Android
Citrix Workspace app for Chrome OS Yes 1908 Feature flag management for Citrix Workspace app for Chrome OS

To access a remotely run app, you need to use a client. There are multiple variants available.

Client Supported platforms
Web browser Any
Client app (“launcher”) Windows, Linux, MacOS

Web browser¶

Bundled client¶

Recent versions of servers have bundled client files. So for example if you start a server on port 9999, you can access it via a browser locally opening http://localhost:9999/ (or https://. if your server is secure).

If your server is located remotely, just use the corresponding host address instead of localhost .

Latest client¶

The latest client is always available at our site: https://projector.jetbrains.com/client/?host=HOST&port=PORT. So this variant is useful if you want to check out the recent update in the client.

You should set HOST and PORT matching your server. For the previous example, it will be https://projector.jetbrains.com/client/?host=localhost&port=9999.

Secure connection is required for the latest client

Your server must be secure when using the latest client because our domain is secure itself. Before connection, make sure that your browser trusts the certificate you use on your server (in this case, connection via the bundled client should succeed). For more info, read below.

The latest client can introduce incompatible changes

The latest client can be incompatible with the latest release or another release that you use.

Known issues¶

Due to limitations of web browsers, there are some issues in the Web Client. They can be solved via native implementations of the client.

iPad as a client¶

iPads don’t support self-signed WebSockets, so if you want to use a browser on iPad as a client, you now have to disable security on the server or use a well-signed certificate on your server.

Some hotkeys are intercepted by the browser¶

For example, Ctrl+Q in Windows/Linux or Cmd+N in Mac is handled by the browser.

Since some shortcuts close the tab or the window, we implemented a confirmation which is shown when the page is about to close (if blockClosing parameter is enabled).

Also, we consider Ctrl+Q shortcut as frequently used, so we mapped it to the F1 button.

It seems that we can’t do anything more about that, at least in a normal browser window.

The proposed workaround here is to you the feature of browsers called PWA. It’s a way to install a web page as a separate application. We’ve tested it in Chrome and in this mode, all the tested shortcuts are handled by Projector, not by the browser. The instructions are as follows: simply create a shortcut by selecting Menu | More Tools | Create Shortcut. and Open as window . Instructions with screenshots can be googled, for example, this one. The similar can be achieved in Firefox: for example, take this instruction.

Incomplete clipboard synchronization¶

There are some limitations with clipboard.

To-server¶

When your clipboard is changed on the client side, the server needs to apply the change on its side.

We implement it on the client side via setting “paste” listener. So clipboard is updated on the server only if you invoke that listener, for example, by hitting Ctrl+V or Ctrl+Shift+V. If you have an application on the server side with a “paste” button, a click on it can paste outdated information unless the listener wasn’t invoked.

Unfortunately, we can’t just continuously get clipboard data from window.navigator.clipboard and send it to the server because when it’s invoked not from user’s context, there will be alert from the browser like “the site wants to read clipboard info, do you grant?”.

To-client¶

It’s vice versa: when your clipboard is changed on the server side, the client needs to apply the change on its side.

We set the clipboard on the client side via window.navigator.clipboard . This doesn’t work in insecure contexts, so the client needs to be opened using HTTPS or on localhost to support this.

We can’t use “copy” listener because when this event is generated, we don’t have a message from the server with actual clipboard data yet. Also, this method won’t work if you click a “copy” button in your application.

It’s not possible to connect to insecure WebSocket from a secure web page¶

This is a limitation of browsers. So for example you can’t use client at https://projector.jetbrains.com/client/ to access an insecure server.

Advanced options and shortcuts¶

The web client has some hidden options and keyboard shortcuts. Please use the links if you want to know more info.

In the future, welcome screen (PRJ-126) and actions panel (PRJ-248) will make these features more explicit.

Client app (“launcher”)¶

Also, we have a special app called launcher that wraps web page and allows to overcome some limitations of web browsers such as shortcut interception and low performance.

Currently, it’s a small app, and it’s easy to use. It has just a single text field for the URL you want to connect.

Downloading¶

Please check releases beginning with the launcher- prefix. Download the file for your OS.

Running¶

After unpacking the archive, run the executable file corresponding to your OS (see below). If you don’t want to specify the URL in the GUI every time, you can create a shortcut or run this app from command line passing the URL as the first argument.

Windows¶

Run projector.exe file.

Linux¶

Run projector file.

Mac (Darwin)¶

Run projector app (on other OSes it’s visible like projector.app dir).

We publish signed notarized and unsigned version of the app. If you want to run the app easily, please use the signed notarized version.

If you want to try the unsigned version, Mac doesn’t allow unsigned apps to be run easily, and will ask you to put the app to Trash Bin. So you need to select “Open Anyway” in System Preferences to allow launching. We believe the only advantage of the unsigned version is that it’s available right away after the new release, and we need some more time to publish the signed notarized version.

When you are ready to start the connection setup, you will also need to install the app HeidiSQL and run it.

Endless hours, and resources are invested in this process. However, despite the efforts, hardening often causes downtime. In fact, over 60% of IT professionals report they’ve experienced downtime while trying to harden their infrastructure.

After years of hardening using the traditional manual tools, we concluded that using hardening automation tools is essential for achieving a successful hardening project and a good compliance posture. Learn more about server hardening automation.

This article aims to provide basic information regarding the Clipboard Redirection setting, which enables the copy past function in remote desktop. Once you’ll decide this setting’s desired value, make sure you test it, to fully understand what will be its impact on your production. This is highly important since you don’t want it to result in damage to production.

In this article you’ll learn:

What is Clipboard Redirection:

The “Do not allow Clipboard redirection” setting specifies whether to prevent the sharing of clipboard contents (clipboard redirection) between a remote computer and a client computer during a Remote Desktop Services session. By disabling this setting you won’t be able to initiate a copy – past action in a remote desktop session.

You can use this setting to prevent users from redirecting clipboard data to and from the remote computer and the local computer.

*If the status is set to Enabled, users cannot redirect clipboard data.

*When Disabled, Remote Desktop Services always allows clipboard redirection (this is the default behavior).

*If the status is set to Not Configured, clipboard redirection is not specified at the Group Policy level. However, an administrator can still disable clipboard redirection using the Remote Desktop Session Host Configuration tool.

Clipboard Redirection Potential Vulnerability:

Microsoft’s clipboard sharing channel supports several data formats such as CF_HDROP, which is responsible for the “Copy & Paste” feature. When used, it allows us to simply copy a group of files from one computer to the other. If the client itself fails to prevent malicious files from entering his computer via this feature, he could be vulnerable to a path traversal attack. The server can then drop malicious files in arbitrary paths on the client’s computer. In other words, the client’s approval of the files is the only thing protecting him from this vulnerability. Considering the fact that the client doesn’t even need to verify the received files coming from the RDP server, it is almost impossible to detect the attack.

How to Mitigate Clipboard Redirection Vulnerability:

attackers commonly use RDP for malicious activity, therefore it is recommended to configure the Remote Desktop Server to only allow required tasks. If you’ve decided that some users do need the clipboard function enabled, it is recommended to segment the LANs that have RDP clipboard enabled, so they can be tracked.

The Potential Impact of Clipboard Redirection Disabling:

As simple as it sounds, remote users won’t be able to use the clipboard functionality. That may lead to damage in production for applications that rely on this ability.

It’s called Paste protection, and its purpose is pretty self-explanatory. While the parent company hasn’t provided too many details on this feature, Paste protection monitors the content you copied and is therefore in your clipboard to make sure no other application modifies it.

For example, some malicious apps out there could monitor your clipboard and change information like bank accounts or crypto wallets in an attempt to trick you into transferring the funds into a different account.

So what Opera does is to monitor the sensitive data that is copied to your clipboards, including bank account information, and then display a warning when other apps attempt to read it.

Feature is currently available for testing

“This festive update brings a new feature that makes browsing safer. One potential risk while browsing is the hijacking of your clipboard. By doing this, someone can replace a bank account number or crypto wallet identifier with a different one,” Opera explained in the release notes of the latest dev build.

“Opera has come up with a secure way to protect you from this. When you copy sensitive data in Opera, the data is monitored for changes for some time or until you paste the data. If the data is changed by an external application, a warning is displayed.”

At this point, there’s no ETA as to when the new feature could go live in the stable builds of the browser, but obviously, it will take a while until this happens given it just made its debut in the dev version. Needless to say, the Paste protection will be available in all supported versions of Opera regardless of the operating system you’re running.

Flutter Secure Storage provides API to store data in secure storage. Keychain is used in iOS, KeyStore based solution is used in Android.

  • Readme

A Flutter plugin to store data in secure storage:

    is used for iOS
  • AES encryption is used for Android. AES secret key is encrypted with RSA and RSA key is stored in KeyStore
  • With V5.0.0 we can use EncryptedSharedPreferences on Android by enabling it in the Android Options like so:

Configure Web Version #

Flutter Secure Storage uses an experimental implementation using WebCrypto. Use at your own risk at this time. Feedback welcome to improve it. The intent is that the browser is creating the private key, and as a result, the encrypted strings in local_storage are not portable to other browsers or other machines and will only work on the same domain.

It is VERY important that you have HTTP Strict Forward Secrecy enabled and the proper headers applied to your responses or you could be subject to a javascript hijack.

Configure Linux Version #

You need libsecret-1-dev and libjsoncpp-dev on your machine to build the project, and libsecret-1-0 and libjsoncpp1 to run the application (add it as a dependency after packaging your app). If you using snapcraft to build the project use the following

Note The current implementation does not support readAll and deleteAll and is subject to change.

Configure MacOS Version #

You also need to add Keychain Sharing as capability to your macOS runner.

Microsoft Edge now can automatically switch users to a secure HTTPS connection when visiting websites over HTTP after enabling Automatic HTTPS.

This new feature is in preview in the Canary and Developer preview channels and is rolling out to select users of Microsoft Edge 92.

The announcement made today by the Microsoft Edge Team comes after the company added the feature to the Microsoft 365 roadmap in April, with an estimated release in July.

“Automatic HTTPS switches your connections to websites from HTTP to HTTPS on sites that are highly likely to support the more secure protocol,” Microsoft said today.

“The list of HTTPS-capable websites is based on Microsoft’s analysis of the web, and helps enable a more secure connection on hundreds of thousands of top domains.”

Blocks MITM attacks, web traffic tampering

The automatic switch to an HTTPS connection will protect Edge users from man-in-the-middle (MITM) attacks attempting to snoop on data exchanged with websites over unencrypted HTTP connections.

Data sent and received over HTTP (including passwords, credit card info, and various other sensitive info) can also be harvested by malicious programs running on a compromised computer.

Ensuring that you’re always using HTTPS when browsing the web helps secure your data while in transit by encrypting the connection to the sites’ servers.

HTTPS also makes sure that threat actors trying to intercept your web traffic will not be able to alter the data exchanged with Internet sites without being detected.

Edge Automatic HTTPS option

How to test it right now

If you want to test it right now, you have to open edge://settings/privacy and turn on “Automatically switch to more secure connections with Automatic HTTPS.”

If the experiment hasn’t reached you yet, you can enable it by going to edge://flags/#edge-automatic-https, toggling on the ‘Automatic HTTPS’ experimental flag, and restarting the browser.

The HTTPS upgrades will be automatic with no alerts to allow you to browse the web just as you usually do, but over a secure connection wherever possible.

While, by default, Automatic HTTPS will only switch to HTTPS on sites likely to support this secure protocol, you can also choose to have all connections switched, which will likely lead to connection errors if the website is missing HTTPS support.

Microsoft is not the first major web browser vendor to add an option to enable HTTPS on all websites automatically.

For instance, Google Chrome defaults to HTTPS for URLs typed in the address bar if no protocol is specified.

Mozilla has also added an HTTPS-Only Mode designed to secures web browsing by rewriting URLs to use the HTTPS protocol (even though disabled by default, it can be enabled from the browser’s settings).

Microsoft has quietly added a ‘Super Duper Secure Mode’ to the Microsoft Edge web browser, a new feature that brings security improvements without significant performance losses.

Users can enable Super Duper Secure Mode after upgrading Edge to stable version 96.0.1054.29 or later, and they can toggle between Balanced and Strict modes for different levels of security increase.

The new feature, under testing by the Edge Vulnerability Research team since August, removes Just-In-Time Compilation (JIT) from the V8 processing pipeline, thus reducing the attack surface threat actors can exploit to hack into Edge users’ systems.

Microsoft describes Super Duper Secure Mode as “a browsing mode in Microsoft Edge where the security of your browser takes priority, providing you an extra layer of protection when browsing the web.”

“We quietly released Super Duper Secure Mode to stable (96.0.1054.29),” said Johnathan Norman, Microsoft Edge Vulnerability Research Lead.

“Balanced learns what sites you use often and trusts those, strict is well.. strict 🙂 Users can now add their own exceptions.”

Enabling Super Duper Secure Mode in Microsoft Edge (BleepingComputer)

When toggled on, Super Duper Secure Mode disables JIT (TurboFan/Sparkplug) and enables Intel’s Control-flow Enforcement Technology (CET), a hardware-based exploit mitigation that provides a more secure browsing experience.

As Norman revealed in August when the feature was first announced, roughly 45% of all security vulnerabilities found in the V8 JavaScript and WebAssembly engine were related to the JIT engine, accounting for over half of all ‘in the wild’ Chrome exploits abusing JIT bugs.

By disabling JIT, the attack surface is drastically reduced by removing almost half of the V8 bugs that should be fixed.

“This reduction in attack surface kills half of the bugs we see in exploits and every remaining bug becomes more difficult to exploit. To put it another way, we lower costs for users but increase costs for attackers,” Norman explained.

In the future, Microsoft aims to include support for Arbitrary Code Guard (ACG) in Super Duper Secure Mode, another security mitigation that would block attackers from loading malicious code into memory, a known technique used by most web browser exploits.

The Edge Vulnerability Research team also plans to ship the new feature with the Android and macOS Edge versions.

At the moment we are disabling JIT and enabling CET in the renderer process. ACG enablement is next after we do some testing. We also have plans for Android and Mac as well. Android being the most interesting since mobile is such a key target 6/?
