Cybereason MalOp
Overview
Cybereason offers a set of Endpoint Detection and Response (EDR) solutions. Through the Cybereason platform, all suspicious operations will be gathered in MalOps, a multi-stage visualizations of device activities.
- Vendor: Cybereason
- Supported environment: SaaS
- Detection based on: Alert
Warning
If your tenant uses an allowlist to authorize connections, please ensure that Sekoia.io's IPs are allowed. See our FAQ to get our IPs.
Configure
This setup guide will lead you into forwarding all MalOp activities to Sekoia.io.
Prerequisites
To forward events produced by Cybereason to Sekoia.io, you will need your Cybereason username and password.
Warning
Please ensure the user has, at least, Analyst L2 rights granted.
Create your intake
On Sekoia.io, go to the Intakes page and generate a new intake with the Cybereason MalOp format.
Keep aside the intake key.
Pull events
To start pulling events, you have to:
- Go to the playbook page and create a new playbook with the Fetch new events from Cybereason module.
- Set up the module configuration with your Cybereason username and password.
- Set up the trigger configuration with your intake key
- Start the playbook and enjoy your events.
Raw Events Samples
In this section, you will find examples of raw logs as generated natively by the source. These examples are provided to help integrators understand the data format before ingestion into Sekoia.io. It is crucial for setting up the correct parsing stages and ensuring that all relevant information is captured.

Detection section
The following section provides information for those who wish to learn more about the detection capabilities enabled by collecting this intake. It includes details about the built-in rule catalog, event categories, and ECS fields extracted from raw events. This is essential for users aiming to create custom detection rules, perform hunting activities, or pivot in the events page.
Related Built-in Rules
The following Sekoia.io built-in rules match the intake Cybereason EDR. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.
SEKOIA.IO x Cybereason EDR on ATT&CK Navigator
Active Directory Data Export Using Csvde

Detects suspicious image loads and file creations from the spoolsv process which could be a sign of an attacker trying to exploit the PrintNightmare vulnerability, CVE-2021-34527. A remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. This works as well as a Local Privilege escalation vulnerability. To fully work the rule requires to log for Loaded DLLs and File Creations, which can be done respectively using the Sysmon's event IDs 7 and 11.

- Effort: advanced
Microsoft Exchange Server Creating Unusual Files
Look for Microsoft Exchange Server’s Unified Messaging service creating non-standard content on disk, which could indicate web shells or other malicious content, suggesting exploitation of CVE-2021-26858 vulnerability
- Effort: intermediate
Microsoft Office Creating Suspicious File
Detects Microsoft Office process (word, excel, powerpoint) creating a suspicious file which corresponds to a script or an executable. This behavior highly corresponds to an executed macro which loads an installation script or a malware payload. The rule requires to log for File Creations to work properly, which can be done through Sysmon Event ID 11.
- Effort: master
NTDS.dit File In Suspicious Directory
The file NTDS.dit is supposed to be located mainly in C:\Windows\NTDS. The rule checks whether the file is in a legitimate directory or not (through file creation events). This is usually really suspicious and could indicate an attacker trying copy the file to then look for users password hashes.
- Effort: advanced
Network Scanning and Discovery
Tools and command lines used for network discovery from current system
- Effort: advanced
Network Sniffing
List of common tools used for network packages sniffing

Network sniffing refers to using the network interface on a system to monitor or capture information sent over a wired or wireless connection. An adversary may place a network interface into promiscuous mode to passively access data in transit over the network, or use span ports to capture a larger amount of data.
- Effort: intermediate
NlTest Usage
Detects attempts to gather information on domain trust relationships that may be used to identify lateral movement opportunities. These command lines were observed in numerous attacks, but also sometimes from legitimate administrators for debugging purposes. The rule does not cover very basics commands but rather the ones that are interesting for attackers to gather information on a domain.

- Effort: elementary
Process Trace Alteration
PTrace syscall provides a means by which one process ("tracer") may observe and control the execution of another process ("tracee") and examine and change the tracee's memory and registers. Attacker might want to abuse ptrace functionnality to analyse memory process. It requires to be admin or set ptrace_scope to 0 to allow all user to trace any process.
- Effort: advanced
PsExec Process
Detects PsExec execution, command line which contains pstools or installation of the PsExec service. PsExec is a SysInternals which can be used to execute a program on another computer. The tool is as much used by attackers as by administrators.

- Effort: advanced
Suspicious PROCEXP152.sys File Created In Tmp
Detects the creation of the PROCEXP152.sys file in the application-data local temporary folder. This driver is used by Sysinternals Process Explorer but also by KDU (https://github.com/hfiref0x/KDU) or Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs), which uses KDU. Note - Clever attackers may easily bypass this detection by just renaming the driver filename. Therefore just Medium-level and don't rely on it.
