Qyick Ransomware

Qyick Ransomware

Introduction: In August 2022, a new and notable threat emerged in the cyber landscape – Qyick Ransomware. Distinguished itself with a unique approach, Qyick operates as a Ransomware-as-a-Service (RaaS) and utilizes the efficient Go programming language. This analysis delves into the characteristics of Qyick Ransomware, covering its emergence, target sectors, spreading mechanisms, technical intricacies, detection strategies, mitigation measures, and removal processes.

Qyick Ransomware Overview:

• Emergence:
  • First observed in August 2022.
  • Gained attention for being sold as a Ransomware-as-a-Service (RaaS) on dark web markets.
  • Developed in Go programming language, known for efficiency.
  • Offers customization levels for payloads with ‘lease’ rates ranging from 0.2BTC to 1.5BTC.

Targets:

• Victim Spectrum:
  • Targets a wide spectrum, including large enterprises, high-value targets, and small to medium businesses (SMBs).
  • Flexibility in targeting due to the RaaS model where affiliates choose victims based on preferences.

Spread Mechanisms:

• Distribution Channels:
  • Primarily spreads through phishing and spear-phishing emails.
  • Exploits exposed and vulnerable applications and services.
  • Utilizes third-party frameworks like Empire, Metasploit, and Cobalt Strike for network infiltration.

Technical Details:

• RaaS Model:
  • Advertised by ‘lucrostm’ on a TOR-based crime market.
  • One-time purchase with prices ranging from 0.2 BTC to 1.5 BTC.
  • Buyers can tailor the ransomware based on their preferences.
  • Unique offering with intermittent encryption technique for accelerated encryption.
  • No data exfiltration capabilities in the current version.

Detection Strategies:

• EDR is equipped to detect and thwart malicious behaviors and artifacts associated with Qyick Ransomware.

Mitigation Measures:

• Employ EDR to identify and neutralize the risks associated with Qyick, ensuring a secure digital environment.

Removal Process:

• EDR customers are well-protected against Qyick Ransomware. The platform’s proactive defense mechanisms eliminate the need for additional actions. In cases where the policy is set to ‘Detect Only’ and infection occurs, the platform’s rollback capability reverses the malicious impact and restores encrypted files, as demonstrated in the accompanying video.

Incident Response:

1. Detection:
   • Identify signs of Qyick ransomware through security tools and network monitoring.
2. Isolation:
   • Disconnect infected devices from the network to prevent further spread.
3. Removal:
   • Run a malware scan using anti-malware tools to eliminate Qyick ransomware.
4. Restoration:
   • Restore encrypted files from backups for data recovery.
5. Expert Consultation:
   • Seek assistance from security experts for a comprehensive assessment and prevention of future attacks.

Proactive Measures:

• Employee Education: Raise awareness among employees about ransomware risks and phishing threats.
• Strong Passwords: Implement strong, unique passwords with regular updates.
• Multi-Factor Authentication: Enable MFA for an additional layer of security.
• Systems Update: Regularly update and patch systems to fix vulnerabilities.
• Backup and Recovery: Implement a robust backup and disaster recovery plan, regularly testing backups for efficacy.
