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.

Warning

This format is still in beta. Use it wisely

Benefit from SEKOIA.IO built-in rules and upgrade Cybereason MalOp with the following detection capabilities out-of-the-box.

SEKOIA.IO x Cybereason MalOp on ATT&CK Navigator

Cron Files Alteration

Cron Files and Cron Directory alteration used by attacker for persistency or privilege escalation.

  • Effort: advanced
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
Exfiltration And Tunneling Tools Execution

Execution of well known tools for data exfiltration and tunneling

  • Effort: advanced
Hijack Legit RDP Session To Move Laterally

Identifies suspicious file creations in the startup folder of a remote system. An adversary could abuse this to move laterally by dropping a malicious script or executable that will be executed after a reboot or user logon.

  • 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: intermediate
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

  • Effort: advanced
Package Manager Alteration

Package manager (eg: apt, yum) can be altered to install malicious software

  • Effort: advanced
RYUK Ransomeware - martinstevens Username

Detects user name "martinstevens". Wizard Spider is used to add the user name "martinstevens" to the AD of its victims. It was observed in several campaigns; in 2019 and 2020.

  • Effort: elementary
SSH Authorized Key Alteration

The file authorized_keys is used by SSH server to identify SSH keys that are authorized to connect to the host, alteration of one of those files might indicate a user compromision

  • Effort: advanced
SolarWinds Suspicious File Creation

Detects SolarWinds process creating a file with a suspicious extension. The process solarwinds.businesslayerhost.exe created an unexpected file whose extension is ".exe", ".ps1", ".jpg", ".png" or ".dll".

  • Effort: intermediate
Suspicious Double Extension

Detects suspicious use of an .exe extension after a non-executable file extension like .pdf.exe, a set of spaces or underlines to cloak the executable file in spearphishing campaigns

  • Effort: elementary
System Info Discovery

System info discovery, attempt to detects basic command use to fingerprint a host

  • Effort: master
WCE wceaux.dll Creation

Detects wceaux.dll creation while Windows Credentials Editor (WCE) is executed.

  • Effort: intermediate
WMI Persistence Script Event Consumer File Write

Detects file writes through WMI script event consumer.

  • Effort: advanced
Webshell Creation

Detects possible webshell file creation. It requires File Creation monitoring, which can be done using Sysmon's Event ID 11. However the recommended SwiftOnSecurity configuration does not fully cover the needs for this rule, it needs to be updated with the proper file names extensions.

  • Effort: master

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.

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: 1. Go to the playbook page and create a new playbook with the Fetch new events from Cybereason module. 2. Set up the module configuration with your Cybereason username and password. 3. Set up the trigger configuration with your intake key 4. Start the playbook and enjoy your events.
