Chrome reports ShareFile sub-domain as a phishing website

As of 25 March 2021, Google safe browsing is incorrectly reporting that some sharefile.eu sites are suspected phishing sites. This also appears to affect Firefox for users with certain plugins enabled.

Citrix are actively working with Google to resolve the issue.

Note:- The error is only seen when using the Web interface. Citrix Files apps for Windows / macOS / mobile platforms are not affected. The plugins for Outlook are also not affected.

Driving Openness & Innovation Through the Modern Computing Alliance

We’re living through a time of rapid transformation—where technology that helps us connect, collaborate and communicate has taken center stage. We’ve been talking about this period as the “Renaissance of the PC”, where we have a unique opportunity to think and do differently to drive better customer experiences. This “renaissance” doesn’t only apply to the device itself, but how the broader computing ecosystem can come together to drive modern experiences.

Today we’re doing just that with the Modern Computing Alliance. We’ve joined as a proud founding member, alongside Google, Intel, VMware, Citrix and many other members.

What is our goal with the Modern Computing Alliance? It’s simple: to drive an open and innovative ecosystem so customers can get the most from their Chrome OS experiences.

Take our Latitude Chromebooks as an example. We already give IT departments the flexibility to easily integrate the Chrome OS into their ecosystem while still enjoying the global availability, scale and features that our Latitude devices offer.

The Modern Computing Alliance will further build on this idea.

We will collaborate with everyone from software partners to Silicon Valley start-ups to drive more value and innovation for Chrome OS in the broader IT ecosystem. Looking beyond devices, we’ll explore things like data security, insights and multi-factor authentication to create more value and innovation for people like you and me. People that use our devices every day.

If there’s anything I’ve learned this year, it’s that our diverse viewpoints and collective strengths can bring about amazing changes – a “renaissance” – for customers and for ourselves. Our goal for our work with the Alliance is that we bring even more innovative, flexible experiences to you. Learn more here.

    Users Prompted to Download, Run, Open “.ica” File Instead of Launching Connection

    In recent releases of IE, Edge, Google Chrome, Firefox, and latest Citrix Workspace App clients many of the issues mentioned below have been resolved.

    By default, the OS (Windows, Mac, Linux) should automatically set how to open “.ica” files when trying to launch any resource via Citrix Workspace or Citrix Storefront via the Web Store if the Citrix Workspace App is installed properly.

    Confirm Citrix Workspace App is installed or use Citrix Workspace App for HTML5 (“Web Browser” option) instead.

    If you continue to encounter this behavior please review the steps outlined below.

    There can be a number of resolutions to the issue including but not limited to the following:

    Install the Latest Version of Citrix Workspace App

    Install the latest Citrix Workspace App version which can be downloaded here: Download Citrix Workspace App

    Automatically Open ICA Files

    When clicking on an application or desktop to launch via Citrix Workspace or Citrix Storefront on an Internet Browser (not within Citrix Workspace App) and an “.ica” file shows in the download bar on the bottom left please follow these steps to automatically open said file:

    ICA file is downloaded during the process. After the ICA file is downloaded, enable the browser to open similar files automatically.

    Note: Instructions below are similar for other OS’s when using Google Chrome, Firefox, or Edge Browsers.

    Internet Explorer:

    1. Navigate to the Citrix Workspace Store or Citrix Storefront Store
    2. Select the resource you are trying to access – Application or Desktop
    3. You will receive a notification on the bottom of the browser to “Open, Save, Cancel”
    4. Select the Save.
    5. The download bar will now show to “Open, Open Folder, View Downloads”,
    6. Select the drop-down list next to “Open” and select “Open With”
    7. Find and select “Connection Manager”

    Google Chrome:

    1. Navigate to the Citrix Workspace Store or Citrix Storefront Store
    2. Select the resource you are trying to access – Application or Desktop
    3. Chrome will prompt a dialog box to save the ‘”.ica” file
    4. Hit save to save it in the “Downloads folder”
    5. On the bottom left you will see the file, click the “^” which is the drop-down list for the file in the download bar and select “Always Open Files of This Type”

    Firefox:

    1. Navigate to the Citrix Workspace Store or Citrix Storefront Store
    2. Select the resource you are trying to access – Application or Desktop
    3. Firefox will prompt you with a dialog box to save the ‘”.ica” file
    4. Select “Do this automatically for files like this from now on”
    5. Select “Open With” and click “Browse”
    6. Select “Connection Manager”

    Edge Browser:

    1. Navigate to the Citrix Workspace Store or Citrix Storefront Store
    2. Select the resource you are trying to access – Application or Desktop
    3. Edge automatically saves the file to the downloads folder by default
    4. On the bottom left you will see the file, click the “…” which is the drop-down list for the file in the download bar and select “Always Open Files of This Type”

    Associate .ica File Type With Citrix Connection Manager

    1. On Windows computers, go to Control Panel > Settings > Apps > Default apps > Choose default apps by file type

    2. Under Name, find .ica file type.

    3. Ensure that the current default is set to Citrix Connection Manager. If not, click Change program and choose Citrix Connection Manager.

    Note: Connection Manager is the wfcrun32 file located as C:Program Files (x86)CitrixICA Clientwfcrun32.exe

    Remove or Disable Third Party Browser Adware

    Remove or disable any third party browser based Adware software that could be interfering with the successful launch of the ICA file. Restart the browser after removing these software and try again.

    Clear the “Do not save encrypted data to disk” Option

    If you are using Internet Explorer, click Tools > Internet Options > Advanced tab and clear the option “Do not save encrypted data to disk.”. This option should be cleared because the dynamic files are stored in the Temporary Internet Files folder. When applications are clicked, a file is downloaded to the folder, then launched using MIME type. If access to the folder is disabled or not available, the process cannot occur successfully.

    App Layering Recipe For Google Chrome 2.6 or Later

    None.
    Unidesk recommends including the OS Type and OS bit level in the name, for Example Google Chrome 31 Win7x32. For versions remember that when choosing a layer you can see the version name but not the version description. Use naming that will allow you to differentiate versions appropriately. For example “1.0 12-12-2013”.
    The basic installation steps are straight forward:

    1. Create a Google Chrome application layer
      1. Install Chrome using the offline installer or msi
      2. Note on extensions
      3. Disable Google Updates (optional)
    2. Configure Chrome AD GPO’s
    3. Apply the layer to desired desktops


    Step 1 Create a Google Chrome Application Layer

    The first step is to install Chrome itself. Download the offline installer from here:

    https://support.google.com/chrome/answer/126299?hl=en

    Choose the Alternate installer for all user accounts. Then install Chrome. It will install into the “Program Files” directory.

    To install extensions please use a GPO http://dev.chromium.org/administrators/policy-list-3#ExtensionInstallForcelist


    Disable Updates

    There are two ways that can be used to disable Google Updates for Chrome. You can use the enterprise GPOs, see the next section or follow this link to disable via the registry

    http://www.chromium.org/administrators/turning-off-auto-updates

    or set the value of HKEY_LOCAL_MACHINESOFTWAREPoliciesGoogleUpdateAutoUpdateCheckPeriodMinutes to the REG_DWORD value of “0”.

    Step 2 (Optional but recommended) Install and configure the Google Enterprise Active Directory Templates In Order To Manage These Settings

    The Goggle Chromium project has created a set of GPO settings that can be used to manage Chrome in an Enterprise Environment.

    Here is where you can download the ADM files and see the documentation:

    https://support.google.com/installer/answer/146164?hl=en

    Once you have the ADM files installed its very easy to configure Chrome settings.

    Updates

    If you are using a GPO to disable updates just add a version to your layer and open Chrome it will automatically update. If you have used the registry setting to disable updates modify the registry setting to a number other than 0 and open chrome, it will update then you can set the registry entry back to 0. Note: If this doesn’t work for you let me know I was not able to test this in the lab.

    If you have enabled any updates through scheduled tasks, disable that as well.

    Considerations for Non-Persistent Desktops

    It is not possible to add custom extensions for a single user with a NP desktop.
