SparkLocker Ransomware

SparkLocker is a newly identified ransomware strain that encrypts files and appends the .spark extension. It demands a ransom of $5,000 in Bitcoin for decryption. Victims are instructed to send payment proof to the attackers to receive the decryption tool. The ransom note is delivered via a text file named OPENME.txt and by changing the desktop wallpaper.

SparkLocker Ransomware Overview

SparkLocker is a crypto-ransomware that employs strong encryption algorithms to lock victims’ files. It targets various file types, rendering them inaccessible. The ransomware modifies the desktop wallpaper and drops a ransom note to inform victims of the encryption and payment instructions.

SparkLocker Ransomware Summary

In-Depth Analysis of SparkLocker

How Did I Get Infected?

SparkLocker primarily spreads through phishing emails containing malicious attachments or links. These emails often appear legitimate, tricking users into opening infected files. Other distribution methods include drive-by downloads from compromised websites, malicious advertisements, and fake software updates.

What Does SparkLocker Do?

Upon execution, SparkLocker encrypts files on the victim’s system, appending the .spark extension to each file. It then changes the desktop wallpaper and creates a ransom note named OPENME.txt, instructing the victim to pay $5,000 in Bitcoin to regain access to their files.

Should You Be Worried for Your System?

Yes. SparkLocker poses a significant threat as it encrypts critical files, leading to potential data loss. Paying the ransom does not guarantee file recovery and only encourages further cybercriminal activity. It is crucial to remove the ransomware and attempt to recover files using secure backups or professional recovery tools.

Ransom Note Text

The ransom note OPENME.txt contains the following message:

pgsqlCopyEditAll your files have been encrypted with SparkLocker.
