Overview

BBSRAT is a type of malware that allows the attackers remotely access the compromised system and execute remote commands, codes, or deploy additional malware in the system. The threat actors behind it are called 'Roaming Tiger' and they are known to specifically target Russia or Russian speaking countries via phishing emails written exclusively in Russian.

Capabilities

Once it's inside your system, the BBSRAT can perform following task:

  1. Execute remote commands and transfer the response to the control server.
  2. Delete all the files related to its activity.
  3. List running processes and cancel the specific ones. 
  4. Receive directory structure and a list of files.
  5. Read, edit, or delete files.
  6. Upload more files from the control server.   



Defensive Measures:

  • Training- As humans tend to make mistakes in an IT industry, a regular social engineering awareness training is recommended, so that, they can become the primary firewall to defend against social engineering attacks.

  • Defense in Depth- An in-depth defense strategy can be applied, that instead of preventing the attack, slows down the progression of the attack just enough, so that the defenders can take action in the meantime. 

  • Intrusion Detection systems- They can be used in order to detect various attacks like buffer overflows, CGI attacks, SMB probes, OS fingerprinting, etc.

  • System Integrity Verifiers (SIV)- Any changes in the system components can be detected while also comparing the snapshots of file systems with the pre-existing baseline snapshots in order to secure against any kind of system intrusion.

  • Multihomed Firewalling- This technique can be used in which firewalls having more than one interfaces to further subdivide the network are required, in order to minimize the amount of damage done by an attacker on a private network.

  • Honeypot- This method is used to attract or trap the attackers trying to gain unauthorized access, in order to learn more about their motives and objectives.

  • Patch Management- The defender must have up-to-date software and firmware patches, so that they can be deployed whenever needed.

  To read part 1, please click  here To read part 2, please click  here Microsoft Monitoring Agent (MMA) MMA is used across multiple Microsoft solutions and has undergone a few name changes as its features and functionality have evolved. If it is being considered to be used, then following areas should be covered during a Microsoft Sentinel deployment project: Consider the timelines and the strategy for a migration to AMA (Azure Monitor Agent) before the MMA end-of-life.  Consider the central deployment and management methodology for MMA. Determine which endpoints are in scope for deployment as these affect the log ingestion volume significantly.  Azure Monitor Agent (AMA) Organizations with MMA as the main Microsoft Sentinel agent should start planning the migration to AMA as soon as possible to avoid a rushed migration. One of the main advantages of AMA is the ability to control the log collection policy centrally and apply different policies against different...

  To read part 2, please click  here To read part 3, please click  here Azure Resources Microsoft Sentinel needs following resources to be created: Subscription (if a dedicated subscription(s) will be used) Resource group(s) Log Analytics workspace(s) Automation rules/playbook Alert rules Workbooks Microsoft Sentinel offers hundreds of alert rules, workbooks, and automation playbook templates along with hunting scripts. The templates can be used to activate/deploy schedule alerts, create customized dashboards, create automation playbooks and perform threat-hunting activities. Generally, once deployed, the resources created have to be adjusted to match the existing environment, configure local credentials, etc. Methods of deployment: Manual- Administrator can manually configures the Microsoft Sentinel resources with the help of Azure portal. Any manual process has the inherent risks of human operator error, lack of compliance with potential change control procedures, and u...

They are also responsible for the following high-level tasks: Initial configuration of Azure tenant, including provisioning required resources, assigning access roles, and configuring workspace parameters like log retention, resource tagging, and blueprints.  Deployment and configuration of syslog/CEF log collection agents in appropriate locations to collect logs from on-premises devices. Generally, it will be joint effort of both system engineer and SIEM engineer, involving configuration and potential troubleshooting.  Working with system owners to enable log forwarding and configuring any required parsing of log data in Log Analytics.  Working with security operations to create and deploy KQL analytic rules to offer detections for SOC/Computer Security Incident Response Team (CSRIT) use.
