Product Overview

Cybereason is an Endpoint Detection and Response (EDR) and Next-Generation Antivirus (NGAV) platform that supports multiple operating systems and deployment options. According to Cybereason, their main differentiator is the MalOp (Malicious Operation), which provides you with the complete picture of the attack rather than overwhelming you with alerts.

In general, Expel supports Cybereason MalOp events ingested through the product’s APIs.

Detection Strategy for Endpoint Integrations

Detection

Our endpoint detection strategy focuses on two common signal types: process and network events. By integrating directly with EDR vendors, we can process security alerts to extract evidence and normalize event details. These normalized signals are then processed through our detection engine to look for signs of post-exploitation activity.

In addition to categorical handling of vendors' security alerts, Expel maintains a large library of behavioral detections to augment vendor detections. When a threat is detected, our automated response bot, Ruxie, takes action by enriching evidence fields with first- and third-party threat intelligence. Additional Ruxie actions query a wide span of technologies directly to arm analysts with key pieces of investigative information and related events.

Response

Endpoints provide rich context for processes and also support other types of Expel Alerts. For example, we use source device identification across a number of alert types when a source IP or hostname is available, because it provides rich context about the actor behind the activity.

Additionally, endpoints provide valuable information for network alerts to help identify what process triggered a connection.

What We Support for Cybereason Endpoint Detection and Response (EDR)

To see a comprehensive list of the most up-to-date Expel detection rules, vendor detection rules, opt-in detections, and available DUETs that we support for Cybereason Endpoint Detection and Response (EDR), you can visit the Detections page in Workbench or ask your Sales or Support rep for the most recent download.

Supported event log sources
  • Cybereason MalOp
Cybereason Endpoint Detection and Response (EDR) detection rules support Yes.

Detection rules written by Expel

Yes.
Auto remediations

Yes. Expel supports automatic execution of some remediation actions for this integration when you follow our setup guide to update the permissions in your vendor device, and then enable the auto remediation in Workbench. The available auto remediations for this integration include:

  • Contain Hosts

To enable auto remediations for your environment, see Enable an Auto Remediation in Workbench in the Help Center.

Investigative support through Workbench Yes. We are able to take the following investigative actions to gather data for triage and investigation of events.
  • Query Hash
  • Query IP
  • Query Domain
  • Query Host
  • Query User
  • Query File
  • Query Comments
  • Retrieve Comments
  • File Frequency
  • Process Network Connections
  • Process Prevalence
  • Process Listing on a host
  • Recent Malops
Hunting support No. Hunting is not currently available for this integration.

Additional Details and Common Questions

Console Access

A vendor alert does not typically include all of the contextual timeline activity surrounding the event of interest. Because this integration does not allow us to get all necessary data via the API, we will ask you for a certain level of console access during onboarding.

The level of access that we require is meant to support essential triage and research activities, and to help us determine the vector and extent of attacker activity for an identified threat. At minimum, we will ask for visibility into alert data, timeline events recorded, and live response/real time response shell (if applicable).

DUET

A DUET rule flags certain events as needing an immediate verification or notification, and bypasses the normal internal event triage process. The events subject to DUET rules contain behaviors that are not typically indicative of true security incidents, as they are related to policy violations or potential risk.

There are a number of workflows that a DUET may follow. When enabled, the activity will be flagged for investigation and will be routed to you (rather than to us) to take a specified first action. To see the specific DUET rules currently supported for this integration, visit the Detections page in Workbench.
