Venus Ransomware

Venus Ransomware

Introduction: Venus Ransomware, making its debut in mid-2021, stands as a significant cyber threat. This analysis provides a comprehensive overview, covering the threat’s emergence, target specifics, propagation methods, technical intricacies, detection mechanisms, mitigation strategies, and removal procedures.

Venus Ransomware Overview:

• Origins:
  • Emerged in mid-2021.
  • Evolved or replaced Zeoticus ransomware.

Distribution and Subscription Model:

• Distribution:
  • Not sold as a traditional Ransomware-as-a-Service (RaaS).
  • All-inclusive package provides a compiled binary and decryptor access.

Target Profile:

• Primary Targets:
  • Large enterprises and high-value targets.
  • Small and medium businesses (SMBs).
  • Targeting strategies may vary among affiliates (subscribers)” for clarity.

Propagation Mechanisms:

• Infection Vectors:
  • Phishing and spear-phishing emails.
  • Exploitation of exposed and vulnerable remote desktop protocol (RDP) services.
  • Utilization of third-party frameworks like Empire, Metasploit, or Cobalt Strike.

Technical Details:

• Package Inclusivity:
  • Similar to Zeoticus ransomware, Venus is an all-inclusive package.
  • Purchase includes access to compiled binary and respective decryptor packages.
  • Currently lacks a public victim portal.
• Execution Process:
  • Initiates multiple processes to terminate inhibiting processes.
  • Sets up the machine for encryption.
  • Launches the ransomware payload.
  • Attempts to cover tracks and block recovery mechanisms, including deletion of Volume Shadow Copies (VSS).
• Targeting and Victimology:
  • Non-discriminatory victimology.
  • No specific industry targeting observed.
• Initial Access:
  • Exploitation of exposed and vulnerable RDP services reported.

Detection Strategies:

• EDR is equipped to detect and prevent malicious behaviors and artifacts associated with Venus Ransomware.
  • Alternate Detection Methods:
    • Employ anti-malware software or security tools capable of identifying ransomware variants.
    • Monitor network traffic for indicators of compromise.
    • Conduct regular security audits and assessments.
    • Educate employees on cybersecurity best practices.
    • Implement a robust backup and recovery plan.

Mitigation Measures:

• EDR provides advanced protection against Venus Ransomware, detecting and preventing malicious behaviors.
  • Additional Mitigation Steps:
    • Educate employees on ransomware risks and phishing identification.
    • Implement strong, regularly updated passwords.
    • Enable multi-factor authentication (MFA) for user accounts.
    • Regularly update and patch systems to address vulnerabilities.
    • Implement a comprehensive backup and disaster recovery (BDR) plan.

Removal Procedures:

• EDR customers are automatically protected from Venus Ransomware. In instances of infection under the “Detect Only” policy, the rollback capability within EDR can be utilized to remove the infection and restore encrypted files.

Conclusion: A thorough understanding of Venus Ransomware’s characteristics is crucial for organizations to bolster their cyber defenses. Implementing advanced threat detection platforms like EDR Singularity XDR, combined with cybersecurity best practices and employee training, enhances resilience against evolving cyber threats.
