XData virus Removal Guide
What is XData ransomware virus?
After using XData ransomware to cause havoc in Ukraine, hackers publish master decryption keys
Xdata virus operates as the ransomware that encrypts files with AES encryption algorithm. The malicious program seems to be attacking Ukraine mainly, although there are victims in Russia, Estonia and Germany. The virus presents quite a plain design as it does not launch its specific GUI. Instead, it opens HOW_CAN_I_DECRYPT_MY_FILES.txt with the instructions how to locate ID and contact hackers via email addresses. Surprisingly, the perpetrators present even 6 of them: firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com. The domain names suggest that hacker was in a good mood generating the malware, however, victims of this malware experience the feeling far from joy. Not only their files now are marked with .~xdata~ file extension, but they remain locked as well. Furthermore, it seems that the malware is designed based on the trojan which has emerged several years ago – HEUR:Trojan.Win32.Generic. Furthermore, it seems that the malware uses more than 20 IP addresses to cover tracks. Until the decryption tool will be created, we recommend you to proceed to Xdata removal. For that purpose, you may find ReimageIntego or Malwarebytes useful.
UPDATE: On 30 May, 2017 hackers revealed master decryption keys of XData ransomware. Thanks to that, Kaspersky and Avast have already released decrypters for this virus. You should run them right after removing the virus from your system.
The ransom note suggests that the malware employs ordinary encryption method, specifically public key to encode netizens‘ data. As a rule, in order to decrypt the files, users need to obtain a unique private key. The cyber criminals seem to be using Command and Control server to store the key. This feature also grants more flexibility to manage several registered domains and, likewise, grant more anonymity. Furthermore, the penetrators ask users to find their ID by locating the file with .key.~xdata~ file extension. Then, they should contact hackers via indicated email addresses. The ransom note left by Xdata ransomware does not present any specific amount of ransom. Such peculiarity might be explained from two perspectives: either the hackers forgot to provide it, or they are ready for negotiations. In any case, we do not recommend contacting the criminals. It is understandable if you decide to risk paying the money but note that there is no guarantee that the hackers will return the files. Thus, you might want to remove Xdata completely.
Starting with the first day of xData ransomware appearance, researchers noticed that the virus mainly rampages in Ukraine. Surprisingly, they report that the virus managed to infect four times more computers than an infamous WannaCry succeeded in a whole week. What’s shocking is that WannaCry was mainly acting on a global scale, while the new computer virus targets only one country mainly. There is no surprise that X Data virus managed to jump into the second position of the most active ransomware families on May 19, and the only virus that it failed to surpass was Cerber.
XDATA malware is still under investigation, but virus researchers expect it to be decryptable.
Methods used to distribute ransomware
There are several distribution methods used by hackers to increase the number of computers infected with ransowmare. Most popular of them is targeting users with spam emails. Note that emails which report about undelivered packages, present invoices or another important documents might be fake and hide a highly troublesome virus. Thus, by opening such file, you may allow XData ransomware or another ransomware to infect your computer. The ransomware starts these processes on an infected host – msaddc.exe, mscomrpc.exe, msdcom.exe, msdns.exe, mssecsvc.exe, mssql.exe and msdcom.exe. To lower the risk of infection, proper security application should be installed. If you already have one and it just quarantined one of the following detections – Trojan.Heur.TP.E72C6B, Gen:Trojan.Heur.TP.eqW@baZ37zo or Ransom_XDATA.A, you should know that XData virus just attempted to encrypt files on your system.
Xdata ransomware removal
When it comes to ransomware removal, users should opt for automatic elimination method. Unless you are an IT security specialist yourself, it would be futile to track all malware files which are spread throughout the entire system. Only after you remove Xdata virus, you may proceed data recovery instructions. Some of them might be of use to you. Lastly, if you are about to enable new browser extensions or install new applications when UAC message pops up and asks you to enable the installation of new files, beware of the above-mentioned executable files. If the program, downloaded from entertainment websites, asks you to enable msaddc.exe or msdcom.exe, you should be alerted because you might need to think about XData ransowmare removal after enabling them.

How to prevent from getting ransomware
Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
