How to remove FunkLocker (FunkSec) Ransomware and decrypt .funksec files

What is FunkLocker (FunkSec) Ransomware

FunkLocker (FunkSec) Ransomware represents a recent strain in the ongoing waves of sophisticated ransomware attacks. This malware encrypts victim files, altering their extensions with a distinctive .funksec suffix, rendering them inaccessible. For instance, a typical image.jpg file metamorphoses into image.jpg.funksec after encryption. Using advanced cryptographic methods, typically asymmetric encryption, FunkLocker ensures that decrypting the affected files without the correct decryption key is nearly impossible. Upon infection, the ransomware dramatically alters the system’s desktop wallpaper and places a ransom note titled README-[random_string].md on the infested device. This note details a chilling ultimatum where attackers demand a ransom, often in the form of 0.1 Bitcoin, to supposedly provide a decryption key. Victims are typically cautioned against engaging with law enforcement or third-party mitigation efforts and often find limited resolution routes without succumbing to the criminals’ demands.

Current industry insights suggest that there are no publicly available decryption tools capable of fully restoring files encrypted by FunkLocker without the attackers’ supposed decryptor. This absence of tools highlights the complexity and efficacy of the cryptography employed by the ransomware. However, experts continually assess the situation and advise victims to avoid paying the ransom due to the inherent risk of non-recovery even after payment. Instead, if victims are to recover their files encrypted with the .funksec extension, they are encouraged to consult the No More Ransom Project or reach out to cybersecurity professionals who may have updated insights or potential yet undiscovered solutions. Regular backups to secure, isolated locations can be vital. While it is not currently possible to decrypt .funksec files without the attacker’s tools, mitigating further damage through isolation and reporting to cybercrime authorities remains crucial for any successful outcome.

How FunkLocker (FunkSec) Ransomware infects computers

FunkLocker (FunkSec) Ransomware primarily infects computers through phishing and social engineering tactics. Cybercriminals disguise malicious software as legitimate files, often delivered via email attachments, which can be documents, executables, or archives. Users inadvertently download and open these files, triggering the ransomware. Additionally, FunkLocker can spread through drive-by downloads from compromised websites, fake software updates, and illegal software cracks. Once executed, the ransomware encrypts files, appending a “.funksec” extension, and demands a ransom in Bitcoin for decryption. Its propagation is further facilitated by exploiting vulnerabilities in outdated software and infiltrating networks through unsecured remote desktop connections.

How to decrypt and restore .funksec files

Use automated decryptors

Download Kaspersky RakhniDecryptor

Use the following tool from Kaspersky called Rakhni Decryptor, that can decrypt .funksec files. Download it here:

There is no purpose to pay the ransom because there is no guarantee you will receive the key, but you will put your bank credentials at risk.

Dr.Web Rescue Pack

Famous antivirus vendor Dr. Web provides free decryption service for the owners of its products: Dr.Web Security Space or Dr.Web Enterprise Security Suite. Other users can ask for help in the decryption of .funksec files by uploading samples to Dr. Web Ransomware Decryption Service. Analyzing files will be performed free of charge and if files are decryptable, all you need to do is purchase a 2-year license of Dr.Web Security Space worth $120 or less. Otherwise, you don’t have to pay.

If you are infected with FunkLocker (FunkSec) Ransomware and removed from your computer, you can try to decrypt your files. Antivirus vendors and individuals create free decryptors for some crypto-lockers. To attempt to decrypt them manually, you can do the following:

How to protect computer from viruses, like FunkLocker (FunkSec) Ransomware, in future

1. Get special anti-ransomware software

Use ZoneAlarm Anti-Ransomware

ZoneAlarm Anti-Ransomware Dashboard

ZoneAlarm Anti-Ransomware Alert

ZoneAlarm Anti-Ransomware Blocked

Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. FunkLocker (FunkSec) Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
