Exploiting Vulnerabilities and Misconfigurations

The Lucifer malware targets misconfigurations and known vulnerabilities within Apache Hadoop and Apache Druid environments, according to the Aquasec report.

One of the critical vulnerabilities exploited is CVE-2021-25646, a command injection vulnerability in Apache Druid that allows authenticated attackers to execute arbitrary code.

By exploiting these weaknesses, attackers gain unauthorized access to the systems, enabling them to carry out their nefarious activities.

Combining Cryptojacking and DDoS Attacks

Combining cryptojacking and DDoS capabilities, its hybrid nature sets the Lucifer malware apart.

Once the malware gains a foothold, it transforms vulnerable Linux servers into Monero cryptomining bots.

  • The campaign operates in distinct phases, showcasing evolving attacker tactics.
  • Initial focus on exploiting misconfigured Hadoop servers.
  • The malware deployment strategy involved dropping two binary files on the compromised server, with one executing the malware.
  • Shifted focus to Apache Druid servers, exploiting the CVE-2021-25646 vulnerability to download and execute the Lucifer malware.
  • Highlights attackers’ adaptability and persistence.
  • Emphasizes the importance of maintaining robust security measures.
  • Advises organizations to review Apache Hadoop and Druid configurations for common misconfigurations.
  • Recommends ensuring all systems are patched and up-to-date to mitigate the risk of such attacks.

Implications and Recommendations

The emergence of the Lucifer malware targeting Apache’s big-data stack serves as a stark reminder of the ever-present cyber threats facing organizations.

With over 3,000 unique attacks detected in just the past month, the urgency for heightened security measures cannot be overstated. 

Organizations must proactively scan their environments for vulnerabilities, apply necessary patches, and employ runtime detection to identify and thwart unknown threats.

As the cyber threat landscape evolves, staying informed and vigilant is paramount.

The Lucifer DDoS botnet malware campaign targeting Apache Hadoop and Apache Druid servers exemplifies attackers’ sophisticated tactics to exploit vulnerabilities and misconfigurations for malicious gain.

Organizations can safeguard their critical infrastructure against such insidious threats by adopting comprehensive security strategies.
