This article explains the issues that occur in case of infection with XUY ransomware. Below you will also find a complete guide on how to remove all malicious files from the infected system and how to potentially recover .xuy files.

XUY is ransomware infection that invades computer systems, plagues their settings and corrupts valuable files. During the attack, this ransomware utilizes sophisticated cipher algorithm that transforms the code of target files and leaves them out of order. Upon encryption you see all corrupted files marked with the extension .xuy. Hackers attempt to blackmail you into paying a ransom of $400 for file decryptor. The extortion happens with the help of a ransom message that loads on the screen at the end of the attack.

XUY Ransomware – Distribution

An infection with XUY ransomware is triggered by a malicious executable file called XyuEncrypt.exe. The distribution of this file may be supported by different techniques such as malspam, fake software updates, malvertising, and compromised freeware.

The main one is believed to be malspam (email messages that deliver malicious software). The implementation of this technique happens with the help of massive spam email campaigns. Currently, campaigns may be targeting users worldwide. Hackers prefer malspam due to the fact that they could easily obtain large number of users’ email addresses released on underground markets on the

the dark web. This provides a lot for the efficiency of their campaigns.

As of the emails they could pose as representatives of well-known companies like

PayPal, DHL, FedEx, and Amazon in an attempts to make you more prone to follow the instructions listed in their text messages. These emails usually aim to trick you to download a file attachment or follow a URL address. Unfortunately, the moment you take the bite and open the attached file or visit the presented web page you unnoticeably trigger XUY ransomware payload on your device.

XUY Ransomware – Overview

XUY is the name of ransomware infection that compromises your computer in order to encrypt your precious files. Once started on the device, the payload of this ransomware access various system parts and performs sequence of malicious changes. Some of the changes enable the threat to prevent being detected by active security measures while other grant for its persistent presence on the system.

Except the payload file, the ransomware may need to establish additional malicious files either by dropping them from its command and control server or by writing them directly on the system. Here is where XUY may locate some of these malicious files:

  • %Roaming%
  • %Windows%
  • %AppData%
  • %Local%
  • %Temp%

At the end of the attack when all needed system settings are corrupted and all target files encrypted, XUY ransomware drops a ransom note file and loads it on the screen. The message in this file informs you about the presence of the ransomware on your device. It also extorts a ransom fee of $400 in Bitcoin.

Here is the full text:

“Works for XUY”
Your personal files were encrypted.
You have 12 hours to decrypt the files.
For the interpretation of it came bitcoins for 400€ at this address: 12ZhVHBfxdwsstomsT6mzz18jTKN7uTc2r
Send evidence photos to the address
Then we will send you the recovery tool via email!
If there is no payment, all data will be merged into The Internet.
Any attempt to decrypt files will damage your files.
NOTICE. Even if you fix the MBR, your PC is dead.
The whole registry is fucked and your files are infected.

XUY Ransomware – Encryption Process

Soon after XUY ransomware finishes the process of modifying system settings it activates an encryption module. This module is designed to locate all target files and encode them by applying sophisticated cipher algorithm. At this point, there is no information about the exact cipher algorithm used by this crypto virus. However, once it changes the original code of target files they become inaccessible for an unspecified period of time.

One way for decrypting files is by paying hackers the demanded ransom of $400. However, our advice is to avoid ransom payment as you may only lose your money. There is no guarantee that the decryptor possessed by hackers is working one. Only a single bug in their ransomware code could result in the generation of a completely inefficient decryption key.

Since it is important to restore your valuable files we could recommend you to try alternative data recovery tools for this process. We have tested several restoration approaches and listed efficient ones under step “Restore Files” that is part of the guide below.

As of the types of data corrupted by XUY ransomware they may be all your:

  • Archives
  • Backups
  • Images
  • Videos
  • Music
  • Documents

Following encryption, they will appear as broken files that could not be opened by any of the installed programs. They could be also recognized by the specific extension .xuy appended to their names.

The XUY is a threat with highly complex code that plagues not only your files but your whole system. So before you could use your infected system regularly again you should properly clean and secure it.

Choose the manual removal approach if you feel sure that you could recognize malware files. If you don’t feel comfortable with the manual steps select the automatic section from the guide. Steps there enable you to check the infected system for ransomware files and remove them with a few mouse clicks.

In order to keep your system safe from ransomware and other types of malware in future, you should install and maintain a reliable anti-malware program. Additional security layer that could prevent the occurrence of ransomware attacks is

anti-ransomware tool.

Make sure to read carefully all the details mentioned in the step “Restore files” if you want to understand how to fix encrypted files without paying the ransom. Beware that before data recovery process you should back up all encrypted files to an external drive as this will prevent their irreversible loss.
