Understanding Jeffery Ransomware
Jeffery ransomware is a malicious software that encrypts files on infected systems, appending a “.Jeffery” extension to each affected file. For instance, “document.pdf” becomes “document.pdf.Jeffery”. Post-encryption, it alters the desktop wallpaper and generates a ransom note titled “JEFFERY_README.txt”, instructing victims to contact the attackers for decryption instructions.

Jeffery Ransomware’s Impact on ESXi and Windows Servers
ESXi Servers:
Jeffery ransomware targets VMware ESXi hypervisors, exploiting vulnerabilities to gain administrative access. Once infiltrated, it encrypts virtual machine files at the datastore level, rendering entire virtual environments inaccessible. This attack vector can disrupt critical operations, leading to significant downtime and financial losses.
Windows Servers:
On Windows platforms, Jeffery ransomware employs sophisticated techniques to infiltrate servers, encrypting essential files and databases. The encryption process utilizes robust algorithms, making unauthorized decryption virtually impossible. The resultant operational disruptions can have severe financial and reputational consequences for affected organizations.
Detection and Indicators of Compromise
Identifying a Jeffery ransomware infection involves recognizing specific indicators:
- File Extension Changes: Files are appended with the “.Jeffery” extension.
- Ransom Note Appearance: The presence of “JEFFERY_README.txt” files and altered desktop wallpapers with ransom instructions.
- System Performance Issues: Notable slowdowns or unusual system behavior due to the encryption process.
- Unusual Network Activity: Unexpected outbound connections as the malware communicates with command-and-control servers.
Encryption Techniques Employed
Jeffery ransomware utilizes a combination of symmetric (AES) and asymmetric (RSA) encryption algorithms. This dual approach ensures that each file is uniquely encrypted, and decryption without the corresponding key is exceedingly difficult.
