SparkLocker is a dangerous ransomware strain that encrypts users’ personal files and demands a ransom—typically $5,000 in Bitcoin—in exchange for a decryption tool. Victims are left unable to access their documents, photos, and other vital data unless they comply with the attackers’ demands. However, even payment does not guarantee file recovery.

Detailed Threat Evaluation
How Did I Get Infected?
Most SparkLocker infections occur through phishing emails with malicious attachments, fake software downloads, cracked applications, or compromised websites. Once a user opens the malicious file, the ransomware silently installs and starts encrypting files.
What Does SparkLocker Do?
After execution, SparkLocker scans the system for common file types, encrypts them using a strong algorithm, and appends the .spark extension to each. It then places a ransom note (OPENME.txt) in affected directories and often modifies the desktop background with further instructions. It demands a $5,000 Bitcoin payment in exchange for a decryptor.
Should You Be Worried?
Yes. SparkLocker uses robust encryption that is nearly impossible to reverse without the private decryption key, which only the attackers possess. Paying the ransom is not advisable, as many victims never receive a working decryptor even after payment. The risk to personal data and business continuity is severe.
