Ransomware is extra harmful than ever earlier than. Why? It’s partly as a result of profitable assaults don’t simply have an effect on the sufferer anymore.
Take the Colonial Pipeline assault for example. As reported by Reuters, the ransomware an infection didn’t simply disrupt the movement of gasoline to cities immediately served by the Colonial Pipeline. It additionally precipitated panic shopping for of gasoline in cities like Miami and Tampa—areas that don’t depend on the pipeline for gasoline. Such exercise drove up the worth of fuel by 20-30 cents in some areas.
Concurrently, ransomware actors want to revenue off profitable assaults as a lot as doable. Per Threatpost, malicious actors are turning to prospects, companions, and different third events who’re associated to the preliminary sufferer. Typically, they’re focusing on these entities with ransom calls for of their very own. Different instances, they’re utilizing the specter of a knowledge leak to stress them into contacting the preliminary sufferer and demanding that they fulfill the attackers’ calls for.
These sources of collateral injury clarify why ransomware assaults have grow to be so pricey, with Bloomberg reporting that some firms find yourself paying tens of tens of millions of {dollars} in ransom. Clearly, organizations must defend themselves in opposition to ransomware in the event that they’re going to keep away from these and different restoration prices.
Examine Cisco Umbrella Exercise on the Endpoint
What should you might keep safer from ransomware, nevertheless it could try and get into your community?
Cisco helps cut back the danger of ransomware infections with a layered protection method from the endpoint to the cloud edge. We ship built-in defenses that work collectively to supply final visibility with final responsiveness in opposition to ransomware.
Specifically, Cisco Umbrella and Cisco Safe Endpoint type the primary and final traces of protection in your safety structure. With SecureX, you possibly can simply mix the intelligence of those merchandise to get deeper visibility into your setting in an effort to defend in opposition to digital threats like a ransomware an infection.
Inside Cisco Umbrella, we will have a look at the totally different occasions that it logs whereas monitoring DNS site visitors. The Exercise Search web page exhibits data akin to Identification (from Energetic Listing configuration), DNS Sort, Inner IP, Exterior IP, and the motion that Umbrella took on every occasion.
As safety analysts who’re investigating malicious site visitors that Umbrella blocked, we will achieve additional visibility into what occurred by utilizing inside IP addresses to determine the corresponding endpoint. We are able to pivot from Umbrella immediately into Orbital Superior Search, a part of the Cisco Safe Endpoint.
Orbital permits you to question endpoints stay. We offer 200+ predefined queries mapped to MITRE ATT&CK. These queries will be custom-made as wanted. The outcomes of your queries will be saved within the cloud or despatched to different functions akin to Cisco SecureX Risk Response for additional or future investigations.
Beneath, you possibly can see how the SecureX Ribbon works in motion, permitting us to make use of Orbital Superior Search and question our endpoints with out even leaving Umbrella.

Apply Endpoint Intelligence to DNS Safety Robotically
When Cisco Safe Endpoint detects Indicators of Compromise (IOCs) on a tool, the occasion usually comprises DNS data that may very well be worthwhile to Cisco Umbrella. For many circumstances, Cisco Umbrella will have already got decided the disposition of a specific IP, however in sure conditions, we will use the knowledge we study on the endpoint to enhance Cisco Umbrella’s capabilities to dam IPs that beforehand had an unknown disposition.
SecureX Orchestration improves your group’s effectivity by permitting you to create and implement automated workflows. This pattern workflow connects Cisco Umbrella, Cisco Safe Endpoint, and Webex Groups. It runs on a continuing foundation to make sure that there’s by no means a niche in your safety protection that would give ransomware actors a gap.
SecureX Orchestration workflows can run recurrently on a time interval of your selecting. This workflow is designed to examine for Cloud IOCs from Cisco Safe Endpoint after which examine to see if Umbrella has a disposition already for a specific URL.
If there’s a disposition already from Cisco Umbrella, then the workflow strikes onto the following URL. If there’s not a disposition, then that URL is mechanically added to the Umbrella Block Listing. A Webex Message together with the main points of what was blocked and the circumstances round it’s finally posted to the safety workforce’s Webex house.
Within the following presentation, considered one of our Technical Advertising and marketing Engineers talks by means of the workflow stay.
