How FunkLocker (FunkSec) Works

Once the FunkLocker ransomware is executed, it begins its malicious operation by encrypting files on the infected computer. These files will have their original extensions replaced with “.funksec,” rendering them inaccessible. For example, “1.jpg” will be renamed to “1.jpg.funksec.” The encrypted files are now held hostage, and the victim is confronted with a ransom note titled “README-[random_string].md.”

Ransom Note

The ransom note demands that the victim pay 0.1 BTC (Bitcoin cryptocurrency) to receive a decryption tool. At the time of writing, 0.1 BTC is valued at approximately 10,000 USD, but the exact amount fluctuates due to the volatile nature of cryptocurrency markets.

The note provides detailed instructions on how to obtain Bitcoin and transfer it to the cybercriminal’s wallet address. It also warns the victim against contacting authorities or third parties, as well as trying to tamper with the infected files. The message closes with a boastful tone: “Start dancing, ’cause the funk’s got you now!”

Ransom Payment Details

• Ransom Fee: 0.1 BTC
• Payment Instructions:
  • Buy 0.1 Bitcoin from platforms like Coinbase or Blockchain.
  • Download the Sessions app from the provided link.
  • Use the app to communicate with the attackers and receive the decryption key.

How FunkLocker Spreads

FunkLocker typically spreads through malicious attachments in phishing emails, fake software updates, torrent websites, and malicious ads (malvertising). Once a user clicks on an infected file, it executes and begins the encryption process. Some variants of ransomware can also self-propagate through local networks and removable storage devices, like USB drives.

The Dangers of FunkLocker

The primary danger of FunkLocker is the encryption of important files such as documents, images, and videos, rendering them inaccessible without the decryption tool. In addition to encryption, the malware may install additional trojans that steal passwords and personal information, causing further harm. Paying the ransom does not guarantee the attackers will provide the decryption key, making it a risky and ineffective solution.
