Understanding RedLocker Ransomware

RedLocker ransomware is a type of malware classified under the ransomware family. It encrypts files, rendering them inaccessible, and then demands payment from victims to regain access. Our cybersecurity research team uncovered RedLocker during routine analysis of new file submissions to the VirusTotal platform. This ransomware is particularly dangerous due to its ability to rapidly encrypt data and coerce victims into making hasty decisions.

• Encryption Process:
  RedLocker appends affected files with a “.redlocker” extension, making them unreadable. For instance:
  • photos.jpg becomes photos.jpg.redlocker
  • photos.png becomes photos.png.redlocker
• Ransom Note:
  After encryption, RedLocker alters the desktop wallpaper and creates a ransom message in a file named redlocker.bat. This file outlines the attackers’ demands and instructions for payment.
• Ransom Demand:
  The ransom note informs victims that their files have been encrypted and demands $500 in Bitcoin for decryption. However, the ransom doubles if payment is delayed by more than 24 hours, intensifying the urgency for victims.

RedLocker Ransomware Attack on ESXi Servers

RedLocker ransomware has been adapted to target VMware ESXi servers, which are vital for managing virtualized environments. This variant of RedLocker focuses on disrupting entire infrastructures rather than single systems.

• Key Features and Modus Operandi:
  • Targeting ESXi Servers: Exploits vulnerabilities in VMware’s ESXi hypervisor to gain access.
  • Encryption: Utilizes strong encryption methods like RSA and AES to lock virtual machines hosted on the server.
  • Ransom Demand: Threatens to delete encryption keys unless a ransom, typically in cryptocurrency, is paid promptly.

This adaptation highlights the versatility and danger posed by RedLocker ransomware in enterprise settings.

---

RedLocker Ransomware Attack on Windows Servers

In addition to ESXi servers, RedLocker ransomware is notorious for targeting Windows-based server environments. These attacks often exploit unpatched vulnerabilities or misconfigured systems.

• Key Features and Modus Operandi:
  • Targeting Windows Servers: Focuses on encrypting critical data stored in Windows servers, including databases and essential files.
  • Encryption: Employs advanced encryption techniques to lock data.
  • Ransom Demand: Demands payment in cryptocurrency for the decryption key.

The prevalence of these attacks underscores the importance of maintaining updated security measures across all server environments.
