What is RedLocker Ransomware?

RedLocker is a type of malware classified as ransomware. This malicious software encrypts files on the victim’s computer and demands payment in Bitcoin cryptocurrency for their decryption. Once executed on a system, RedLocker appends the “.redlocker” extension to all encrypted files. For instance, a file named “1.jpg” will appear as “1.jpg.redlocker,” while “2.png” becomes “2.png.redlocker.”

The ransomware also changes the desktop wallpaper to notify victims about the attack and provides instructions for paying the ransom. Additionally, RedLocker creates a ransom note file named "redlocker.bat" containing further payment details and warnings about tampering with the encrypted files or using third-party decryption tools.

Ransom Note Overview

The ransom note informs victims that their files have been encrypted and advises them to read the "redlocker.bat" file for detailed instructions. Victims are required to pay $500 in Bitcoin to a specified wallet address within 24 hours. Failure to comply within the given time frame results in the ransom amount doubling.

The batch file reiterates these instructions and warns against renaming the encrypted files or using unauthorized decryption methods, claiming such actions could render the files permanently inaccessible.

Symptoms of Infection

• Previously functional files are no longer accessible and have the ".redlocker" extension.
• A ransom demand message is displayed as the desktop wallpaper.
• A batch file ("redlocker.bat") is created with payment instructions.
• Victims are urged to pay a ransom in Bitcoin for file decryption.

Distribution Methods

RedLocker ransomware typically spreads through the following channels:

1. Email Attachments: Malicious files disguised as legitimate attachments in phishing emails.
2. Malvertising: Deceptive online ads that redirect users to harmful websites.
3. Drive-by Downloads: Automatic downloads initiated without the user’s knowledge.
4. Torrents and File-Sharing Platforms: Infected files shared on unregulated P2P networks.
5. Fake Software Updates: Fraudulent updates for popular applications.
6. Trojan Backdoors: Malicious software that facilitates the download and installation of ransomware.

Consequences of Infection

Once RedLocker is installed on a system:

• All targeted files are encrypted, rendering them unusable.
• Victims are pressured to pay a ransom to recover their files.
• Delayed payment results in increased financial demands.
• Additional malware, such as password stealers, may be installed alongside the ransomware.

Why Paying the Ransom is Not Recommended

Victims are strongly advised against paying the ransom for the following reasons:

• There is no guarantee that the attackers will provide the decryption tool.
• Payment encourages cybercriminals to continue their illegal activities.
• Sending money does not guarantee protection from future attacks.

How to Remove RedLocker Ransomware

Removing RedLocker ransomware involves several steps to ensure the complete elimination of the malware and prevent further encryption of files. Below is a detailed guide:

Step 1: Boot Into Safe Mode

1. Restart your computer.
2. During startup, press the appropriate key (e.g., F8 or Shift + F8) to access the Advanced Boot Options menu.
3. Select Safe Mode with Networking and press Enter.

Step 2: Use SpyHunter to Remove RedLocker

SpyHunter is a powerful anti-malware tool designed to detect and remove ransomware infections. Follow these steps:

1. Download and install SpyHunter.
2. Run a full system scan to detect RedLocker and other associated threats.

   • %Temp%
2. Delete any files associated with RedLocker or other suspicious programs.

Step 4: Restore Files from Backup

If you have created backups of your data, restore your files from an external storage device or cloud service. Ensure that the backup is clean and not connected during the ransomware removal process.

Step 5: Update Security Software

1. Update your antivirus and anti-malware programs to their latest versions.
2. Enable real-time protection and schedule regular system scans.
