Apache Hadoop Servers Under Siege: ‘Lucifer’ Botnet Emerges as New Threat.

DDos Attack

Apache Hadoop Servers Under Siege: ‘Lucifer’ Botnet Emerges as New Threat.

Let’s delve into the three unique attack phases employed by the Lucifer botnet:

  1. Phase 1: Scanning the Internet for Misconfigured Hadoop Instances:
    • During this initial phase, Lucifer actively scans the internet to identify vulnerable Apache Hadoop instances.
    • It seeks out misconfigurations or security weaknesses in Hadoop clusters.
    • Once a potential target is identified, the botnet moves on to the next phase.
  2. Phase 2: Exploiting Misconfigured Hadoop YARN Clusters:
    • In this stage, Lucifer focuses on exploiting a specific component of Hadoop: the Yet Another Resource Negotiator (YARN).
    • YARN is responsible for managing resources and scheduling jobs within the Hadoop ecosystem.
    • The attackers take advantage of misconfigured YARN clusters to gain unauthorized access.
    • By exploiting vulnerabilities, they can execute arbitrary code and potentially compromise the entire cluster.
  3. Phase 3: Downloading and executing the Lucifer Malware:
    • The climax of the attack involves deploying the actual Lucifer malware.
    • This malware combines two powerful capabilities:
      • Cryptojacking: It hijacks computing resources to mine cryptocurrencies without the victim’s knowledge.
      • Distributed Denial of Service (DDoS): It can launch coordinated attacks to overwhelm servers or networks.
    • Once the malware is downloaded onto the compromised Hadoop instance, it can wreak havoc by engaging in both cryptojacking and DDoS activities.

Mitigation Steps:

  1. Patch and Update:
    • Regularly update and patch your Apache Hadoop and Apache Druid installations.
    • Address known vulnerabilities promptly to prevent exploitation.
  2. Configuration Hardening:
    • Review and secure configurations for Hadoop and Druid.
    • Ensure that access controls, authentication mechanisms, and network settings are properly configured.
    • Disable unnecessary services and ports.
  3. Network Segmentation:
    • Isolate Hadoop and Druid clusters from other critical systems.
    • Implement network segmentation to limit lateral movement.
  4. Monitoring and Anomaly Detection:
    • Deploy intrusion detection systems (IDS) and security information and event management (SIEM) solutions.
    • Monitor network traffic, system logs, and user behavior for signs of compromise.
  5. Access Control and Authentication:
    • Enforce strong authentication mechanisms.
    • Limit access to authorized users only.
    • Implement role-based access controls (RBAC).
  6. Regular Security Audits:
    • Conduct periodic security audits to identify misconfigurations and vulnerabilities.
    • Test your defenses against potential attacks.
  7. Incident Response Plan:
    • Develop an incident response plan specific to Hadoop and Druid environments.
    • Define roles, responsibilities, and communication channels.
    • Be prepared to respond swiftly in case of an attack.

Remember, proactive measures are crucial to thwart Lucifer’s fiery intentions!
