If you want to disable this feature, you can disable it for web-based clients on the configuration page of your Bastion resource. This applies to both the Basic and the Standard SKU tier. You don't need to configure anything additional. Prerequisitesīefore you proceed, make sure you have the following items.īy default, Azure Bastion is automatically enabled to allow copy and paste for all sessions connected through the bastion resource. This mean also all potential malicious applications and malware. They don't require any special privileges to access the clipboard.This article helps you copy and paste text to and from virtual machines when using Azure Bastion. New clipboard data detected: Test from iPhoneīy design, the clipboard is available to all processes running on the system. Let’s test again:Īnd, once data copied into the iPhone clipboard, I see in the VM host: New clippboard data detected: uid=501(xavier) gid=20(staff) groups=20(staff),12(everyone),61(localaccounts),79(_appserverusr),80(admin),81(_appserveradm),98(_lpadmin),399(_ssh),701(.1),33(_appstore),100(_lpoperator),204(_developer),250(_analyticsusers),395(_ftp),398(_screensharing),400(_remote_ae)Įven more interesting: I’m an Apple fan and I’ve the complete range of Apple devices, all of them are perfectly integrated…. (pbcopy/pbpaste are MacOS commands to read/write the clipboard, very convenient :-)Īnd immediately, on my Windows VM, my scripts reacts: This means that I can copy/paste between the host and the VM. My Windows host is virtualised and, for more ease of use, the VM is not isolated: You can guess that we have some 2FA tokens, passwords, error messages (that are usually pasted to Google, etc). New clippboard data detected: 'list' object has no attribute 'keys' New clippboard data detected: lwi0b!nui8hAMTlG We see the history of all data copied into the clipboard: Let’s run it and continue to work as usual. It just grabs the content of the clipboard every 0.1 seconds and, if changed, displays the content (note that I’m just handling basic text, binary content is ignored). Write-Host “New clippboard data detected: $data” Here is the very simple code based on Get-Clipboard: This gave me the idea: let’s write a few lines of PowerShell to monitor the content of the clipboard on a Windows 10 host. Note that some Password managers are more "mature" and offer a browser add-on that communicates directly with the main application and bypass the clipboard. Once data has been copied into the clipboard, it can be considered as “lost” if other applications are monitoring its content. This is very convenient but it is NOT a security feature. Some of them implement a technique to restore the content of the clipboard with previous data. You just need to paste data exported by the password manager in the password field. This is true, our clipboards may contain sensitive information like… passwords, private URLs, confidential text, and man more! About passwords, many password managers use the clipboard to make the user’s life easier. At the end of the article, the author gave a reference to an iPhone app that discloses the metadata of pictures copied to the clipboard (like the GPS coordinates). Yesterday I've read an article about the clipboard on iPhones and how it can disclose sensitive information about the device owner.
