Why do my documents and pictures have .kyra file extension?

The .kyra file extension virus is a new version of the Globe Ransomware. Malware does not differ a lot from other file-encrypting viruses: it is distributed via malicious email attachments, after infiltration encrypts files using a sophisticated algorithm and drops a ransom note. Compared to the current popular and dangerous viruses, it might seem that .kyra file extension ransomware is not a hazardous cyber threat – it targets “only” 100 different file types. Indeed, some malware might target four times more file formats. But keep in mind that it targets the most popular files such as .jpg, .doc, .xls, .ppt, .pdf, .mp3, etc. There’s no doubt that all your important work or study documents, pictures from holidays and birthday parties, music or movies collection are taken to hostage. Malware encrypts files using powerful RSA-1024 encryption algorithm and demands a ransom for decryption tool. Victims have to contact hacker and transfer a necessary amount of money; however, this activity might lead to an even bigger loss. Instead of dealing with cyber criminals, remove .kyra file extension virus from the computer. Ransomware elimination is quite difficult and complicated task, so we recommend employing a strong and powerful malware removal tools such as Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus. These programs are created for protecting computers and removing malware.

The most significant feature of the virus is its file extension. Malware “marks” corrupted files with .kyra file extension. Since then users cannot access their personal data and might receive Windows Explorer’s alert that it cannot recognize the file type. Once it happens, users can look for a ransom note called “STRIKE.HTA” that is probably placed on the desktop. Here victims can learn what have happened to their files and how they can get back access to them. Hacker gives 48 hours for users to contact him (or her) by email support-lodang@India.com or using bitmsg.me service, and send their personal key which is provided in the message. The creator of .kyra file extension virus will answer them and send a unique Bitcoin wallet address, where victims have to transfer 1 BTC ($620) in order to use a unique file decoder. However, we do not recommend contacting the hacker and paying the ransom. According to various cyber security specialists, hackers rarely provide necessary data decryption key after they receive a payment. We want to discourage you of transferring the money. Instead of it, initiate .kyra file extension removal.

kyra file extension virus might attack your computer

How can my computer get infected?

Virus researchers found out that .kyra file extension malware spreads via malicious spam emails. We are not surprised about this distribution technique. It seems the most effective and successful infiltration method. It’s already known that this virus sends emails that are supposed to be job applications with attached CV or payment confirmations from various online stores. Therefore, you have to be careful. Before opening an attachment, make sure that you have bought something from a particular store or that your company calls for candidates. If not, do not open these emails. Besides, other file-encrypting viruses might be hidden under different messages, so you should always double check the information before opening attached documents.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove .kyra from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

Unfortunately, virus researchers haven’t cracked the code and haven’t created a free decryption tool that will help to decrypt files encrypted by .kyra file extension virus. Keep in mind that paying the ransom is not an option to restore your files. The hacker may leave you with an even bigger loss. After virus elimination, you can try to recover files using backups or using alternative methods. If you have data backups stored in external devices, connect them to the computer and copy necessary files. If you do not have backups, try additional methods presented below.

If your files are encrypted by .kyra, you can use several methods to restore them:

Restore your files with Data Recovery Pro

It’s the easiest and quickest method to recover corrupted files. However, it might not be able to decrypt all your files yet, but you should give it a try! 

Data recovery with Windows Previous Versions feature

This method will work only if System Restore option has been enabled before ransomware attack. In this case, follow the steps below and restore some of your 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”.

ShadowExplorer might be helpful in data recovery as well

It’s still unknown if .kyra file extension virus removed Volume Shadow Copies from the computer, or not. Usually, file-encrypting viruses do that. However, if it failed, follow the steps below:

  • 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;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from .kyra and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
