YE1337 Ransomware: Overview, Removal Guide, and Prevention Tips

Ransomware attacks are among the most severe and financially damaging types of cyber threats. One of the latest threats that has emerged is YE1337 ransomware. Discovered during a VirusTotal sample inspection, YE1337 is a file-locking malware that encrypts personal files and demands a ransom from the victim. Like many other ransomware strains, it leverages strong encryption methods to lock files, making them inaccessible to the user. The cybercriminals behind YE1337 demand payment for a decryption key, often urging victims to pay in cryptocurrencies like Bitcoin.

YE1337 Ransomware Overview

YE1337 is a type of crypto virus or file-locking ransomware. Once it infects a computer, it locks files by appending the extension .YE1337 to them. These files can no longer be opened until the ransom is paid or a decryption tool is found. The malware also drops a ransom note titled YE1337_read_me.txt and changes the victim’s desktop wallpaper to further pressure them into paying.

The ransomware is often distributed through malicious email attachments, infected software downloads, or compromised websites. The threat is usually spread via malicious attachments in phishing emails or torrent sites offering pirated content.

Symptoms of Infection

• Files with a .YE1337 extension, such as 1.jpg.YE1337, 2.png.YE1337, and so on.
• An inability to open files due to encryption.
• A ransom note titled YE1337_read_me.txt is dropped on the victim's desktop, urging them to pay the ransom for decryption.
• Changes to the desktop wallpaper, often with a message reinforcing the ransom demand.
• Warning messages from the ransomware telling the victim that recovery tools will not work and that the files will remain encrypted forever if the ransom is not paid.

The Ransom Note

Once YE1337 encrypts the victim’s files, it drops a ransom note titled YE1337_read_me.txt. This file contains the ransom message, explaining that the victim's files have been encrypted with a strong encryption algorithm and are now inaccessible. The note warns against using any recovery tools, as they will not work, and suggests that the only way to regain access to the files is by paying the ransom. The note also emphasizes that turning off or disconnecting the computer will result in permanent file loss.

Here's an excerpt from the ransom note:

!!!!!!!!!!!!!!!!!!!!!!!!!!
::YE1337 RANSOMWARE NOTE::
!!!!!!!!!!!!!!!!!!!!!!!!!!
Your personal files have been encrypted by a powerful encryption algorithm. This means that you will not be able to access them anymore, and they will remain encrypted until you pay a ransom.
!!! YOUR FILES WILL REMAIN ENCRYPTED FOREVER IF YOU DON'T PAY !!!
Don't try to use any recovery tools or decryption software, as they will not work. The only way to restore your files is to pay the ransom.
If you shut down or disconnect your computer, you may lose your files forever.

Despite these threats, victims are strongly advised not to pay the ransom. There is no guarantee that the attackers will provide the decryption tool, and paying only fuels further criminal activity.

How to Remove YE1337 Ransomware

Disconnect the Infected Device

The first step in dealing with YE1337 ransomware is to disconnect the infected device from the internet and any network it is connected to. This will prevent the ransomware from communicating with the command-and-control server and spreading to other devices on the network.

Identify and Terminate Malicious Processes

Before proceeding with the removal, check for suspicious processes running in the Task Manager. Some ransomware variants may run hidden processes to maintain persistence. Look for unfamiliar processes that could be linked to YE1337 ransomware.

Remove YE1337 Ransomware Using SpyHunter

SpyHunter is a powerful malware removal tool that can help detect and eliminate ransomware like YE1337. Follow these steps:

• Download and Install SpyHunter: First, ensure that SpyHunter is downloaded from a trusted source. Install the program and launch it.
• Perform a Full System Scan: Open SpyHunter and initiate a comprehensive scan of your system. This will allow SpyHunter to detect any traces of YE1337 ransomware and associated files.
• Quarantine or Remove the Threat: After the scan is complete, SpyHunter will display any threats detected. Quarantine or remove the identified ransomware and any other associated malware.
• Restart Your Computer: Once the ransomware is removed, restart your computer to ensure the malware is completely eradicated from your system.

Restore Files from Backup

If you have a backup, now is the time to restore your encrypted files. Make sure the backup is free from malware before restoring it. If no backup exists, you may need to resort to professional decryption services or wait for security researchers to develop a decryption tool, although these are not guaranteed to succeed.

Preventive Methods Against Future Ransomware Attacks

To protect your system from future ransomware infections, follow these preventive measures:

Maintain Regular Backups

Always keep up-to-date backups of important files, preferably in multiple locations. This will allow you to restore files without paying the ransom if an infection occurs.

Keep Your Software Updated

Ensure that your operating system, antivirus software, and all other programs are regularly updated. Security patches help close vulnerabilities that ransomware and other malware can exploit.

Use Robust Security Software

Install reputable antivirus or anti-malware software and configure it to scan your system automatically. Make sure it offers real-time protection and can detect ransomware threats.

Avoid Suspicious Links and Attachments

Do not click on links or open email attachments from unknown or untrusted sources. Phishing emails are a common method used to distribute ransomware.

Employ Network Segmentation

For businesses and organizations, segmenting the network can help prevent ransomware from spreading across devices. Isolate critical systems and enforce strong access control.

Use Strong Passwords and Multi-Factor Authentication (MFA)

Using strong, unique passwords and enabling multi-factor authentication (MFA) adds an additional layer of security, preventing unauthorized access to your accounts and devices.
