Uridzu might be a new version of Globe Imposter 2.0
Uridzu is a ransomware-type cyber threat that seems to be related to Globe Imposter family. The virus is still under investigation, but researchers assume that it’s a variant of Globe Imposter 2.0, which mostly targeted computer users in China, Egypt, and Hungary. It started encrypting files and appending .crypted_uridzu@aaathats3as_com extension in November 2017.
The file-encrypting virus is capable of encrypting computers and servers. The virus might use RDP attacks to affect devices and spread through the network infecting other computers. Once inside, Uridzu ransomware makes critical system changes, disables computer’s security and starts data encryption.
Questions about Uridzu ransomware
Following data encryption, Uridzu virus delivers a ransom note called “how_to_back_files.html.” It opens a browser’s window which provides information about encrypted files. Here victims are asked to send an email to uridzu@aaathats3as_com and learn how they can get Uridzu decryptor:

It is in your interest to respond as soon as possible to ensure the recovery of your files, because we will not store your decryption keys on our server for a long time.
Your personal ID
Malware researchers warn that criminals will demand to pay a few hundreds of dollars in Bitcoins for a chance to restore files encrypted by Uridzu. However, following these instructions is a huge risk. Criminals may never give you a decryptor once they receive the payment.
The purpose of all ransomware-type cyber threats is to swindle the money from computer users, and data recovery is just the matter of their conscience. Instead of risking to lose your money and increase the damage, you should remove Uridzu from the computer immediately.
Major security programs can detect malware as Trojan-Ransom.Win32.Purgen or under similar names. Thus, you should choose a reliable anti-malware tool for Uridzu removal. If you are not sure which software to use, we recommend ReimageIntego.
Uridzu ransomware asks to contact cyber criminals in order to get decryption software.
The ways how ransomware gets inside computers
Developers of ransomware usually stick to malicious spam emails as the main ransomware distribution method. They include an obfuscated malware payload in the email and write an important reason to convince users into opening it. If a user believes in such trickery, malware gets inside the system and starts data encryption.
However, Uridzu ransomware virus seems to be spread via weak or unprotected Remote Desktop Protocol (RDP) connections as well. Therefore, criminals might use brute-force attacks to install malware on the computers.
Thus, users are advised to be careful with received emails and do not rush opening attachments. Additionally, if you are not using RDP connections, you should disable to prevent the attack. However, if you need it, you have to set strong and hard to break a password.
Remove Uridzu virus from the computer using security software
The only correct way to remove Uridzu from the device is to scan the system with reputable malware removal software. We highly recommend using ReimageIntego or SpyHunter 5Combo Cleaner to wipe out malware-related components entirely. But first, you should reboot the computer to Safe Mode with Networking (instructions are given below).
Keep in mind that Uridzu removal won’t restore your files. It only terminates malicious entries from the system, which is an extremely important task. Currently, you can restore your data just from backups. However, if you do not have them, you can try alternative tools. You can find our recovery suggestions at the end of the article. Though, you should not get high expectations to get back all of the lost data.

The official Uridzu ransomware decryptor is not available yet. However, instead of buying software from cyber criminals, you should try alternative recovery methods to restore at least some of your files.
If your files are encrypted by Uridzu, you can use several methods to restore them:
Try Data Recovery Pro
This recovery is originally created for restoring accidentally deleted or corrupted data. However, victims of ransomware noted that it helps to restore some of the encrypted files as well.
- Download Data Recovery Pro;
- Follow the steps of Data Recovery Setup and install the program on your computer;
- Launch it and scan your computer for files encrypted by Uridzu ransomware;
- Restore them.
Take advantage of Windows Previous Versions feature
If System Restore feature was enabled before ransomware attack, you should follow these steps and recover the most needed individual files:
- Find an encrypted file you need to restore and right-click on it;
- Select “Properties” and go to “Previous versions” tab;
- Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.
Use ShadowExplorer if Uridzu did not delete shadow copies
ShadowExplorer tool recovers files from Shadow Volume Copies. Thus, if they were not deleted, try this tool:
- Download Shadow Explorer (http://shadowexplorer.com/);
- Follow a Shadow Explorer Setup Wizard and install this application on your computer;
- Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;

Uridzu decryptor is not available yet
We will update the information as soon as it will be released.
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Uridzu and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
