New and updated response actions
WithSecure Elements EDR has launched new and updated features response actions.
Retrieve Browser artefacts
This response action retrieves browser history from the device.
If a device is infected with malware, it is very likely because the user has downloaded it via their web browser. By retrieving the browser history, you can find out where the malware was downloaded from (i.e. the source URL).
This new action can be found from response wizard.
Action can be used to collect artefacts from various browsers. Artefacts can be collected for all user accounts (default) or for specified user only.
This one like all other responses can be run in multiple devices with one response definition and results from all selected devices will be available and stored in the management portal.
Delete files
Delete files response action has two new parameters.
When deleting files from devices there is now option to retrieve file before deleting it. This simplifies work flow by combining two actions into one. This response action automatically verifies/checks that file deletion was successful. Delay between executing delete and verifying the result can be configured. This can be used to verify that e.g. persistence mechanism did not restore it after deletion.

Preview of new Broad Context Detection view now available
We are in the process of introducing a new Broad Context Detection (BCD) view to help improve viewing, navigating and filtering the data whilst investigating detections, and you can view the new BCD version by clicking on the link at the top right of the BCD page.
The new BCD view combines the summary process tree and the process details so they are visible together on the same page with no need to switch between the two tabs. Also, the process details are visible on whichever tab you are viewing making it easier to view the process data, for example, when writing up your findings.
This is still a work-in-progress and there is continued focus on improving usability - such as, selecting/de-selecting multiple data points - and the ‘Elevate’ service. Check it out and give us your feedback to help us shape the final version for you - this can be done via our Elements Ideas portal: ideas.withsecure.com.

Release of new Automated Actions view
WithSecure Elements EDR has released a new view called 'Automated actions'.
This replaces the old 'Automated response' view.
What's changed?
The functionality stays the same and you can still configure ‘Device isolation’ rules that run 24/7 and specify the risk level, like with the original 'Automated response' view, however you can now create an action rule with ‘custom’ scheduling where you can input specific hours for when you want a rule to run, for example, outside of office hours.
The new 'Automated actions' view includes all existing Device Isolation rules, so there is no need to worry about having to re-create them.
It includes the new 'custom' scheduling, so specific days and times can be applied for when you want the rules to run, for example, from 17:00 until 09:00 the next morning.
Lastly, the existing 'Automated response' view is still available for the next two weeks, in read-only mode, so you have time to get used to the new view.
Why?
Not only does this new feature provide custom scheduling but it also starts to build towards our vision to include more automated actions within Elements – initially, with the co-monitoring service and the new email notifications with risk level selection, but also for more response actions in the future.
This new Automated Actions view is now available to use in Elements.

Release of new Broad Context Detection details view
The new Broad Context Detection (BCD) details view has been fully released into production and is now the default view, replacing the old Broad Context Detection details view.
What's changed?
The new BCD details view has become the default view so when you click on the ‘Broad Context Detection’ menu option in Elements, you will now be presented with this new view.
The old BCD details view is still available to use to give you more time to familiarise yourself with the new BCD view. You can navigate to the old BCD view via the ‘Go to old Broad Context Detection view’ button in the top right corner of the page.
You are able to elevate BCDs from within the new BCD details view, unlike before when it was in ‘Preview’ mode where you had to navigate back to the old BCD view to elevate a detection. The new view supports both manual and automatic elevations and works exactly the same as the old view.
You are also able to change the default Elevation subscription token selected. The subscription expiring the soonest is selected by default, however you can now see all available subscriptions and change it to another one if you so wish.
Extra information has been added to the new view to help you interpret the information displayed.
Update: Please rest assured there are no immediate plans to remove the old BCD details view. Improvements to the new BCD details view are being made following user feedback, and plenty of warning will be given when the old BCD details view is removed.

Portal performance improvements
WithSecure Elements EDR have released changes to the portal which significantly improves its performance. This change should be noticeable for all users but especially for partners who have a large customer base - for example, improved performance should be seen when navigating between customers (using the scope selector) as there were some instances where the portal was slowing down when changing customer.
Due to this change, you may need to log out completely from Elements and clear your browser's cache, local storage and cookies. This step is only necessary if you find the EDR portal getting stuck on loading and showing only a "spinner".
Note: If you are still having issues after carrying out the above steps then please raise a customer request ticket in the usual way. Please remember to include a full HAR file and, if possible, a screen capture (or even better, a video recording!) of logging into the portal and the loading process, as this will help with troubleshooting the issue.

Exporting data to CSV from the Event Search view
WithSecure Elements EDR has launched new functionality in the Event Search view where you can export the data from the view into a comma-separated value (CSV) file.
The exported data will align with how it is displayed in the portal – for example, if you have added/removed/reordered the columns then this will be the layout (of the data) in the CSV file.
Please note there is currently a maximum limit of 500 rows that can be exported at any one time.
Localisation is supported with this functionality.
Benefits
With this functionality, you now have more flexibility - for example, it allows you to share this information with fellow security analysts offline, combine it with telemetry from other systems, and/or carry out further analysis, such as, using pivot tables in Excel.

New status "Waiting for customer" available for Broad Context Detections
User can now update the status for a BCD as “Waiting for customer”
'Waiting for Customer - The incident is now awaiting confirmation / response from the end customer before it can be progressed.'
The user can also filter the BCDs by this status:
The dashboard also gives an overview of the status:

Next generation of our detection engine
From today, partners and customers will see a new and improved risk score against all EDR Broad Context Detections. The new model learns from your environment using resolution closure codes to assess detection logic
performance. By identifying areas for enhancement, we aim to refine and improve our detection capabilities, achieving a significant reduction in reported BCDs.For more information view the full article here:

We have now introduced “Accepted Behavior,” to all customers, it is now possible to create suppression rules that accept the behavior of a user or process. This feature aids in silencing Broad Context Detections (BCDs) for expected behavior. Partners and customers using WithSecure’s EDR solution can utilize this functionality to allow specific behavior in their environments. For example, if you trust a process called “XYZ” associated with software “ABC,” you can suppress similar BCDs to avoid unnecessary alerts.
Accepted Behavior works by suppressing key detections within a BCD. Each BCD contains one or more key detections that highlight suspicious behavior. Organizations can create suppression rules based on their specific circumstances. However, users should be cautious not to suppress too broadly, as legitimate behavior might also be affected.
Limitations of the release include enabling “accepted behavior” on BCDs with up to 5 key detections. We will soon be addressing this and dealing with cases where identical rules are created due to repeating key detections.
Watch this space for more Accepted Behavior improvement announcements.
