removal by Julie Splinters - - | Type: Ransomware

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 Malwarebytes. These programs are created for protecting computers and removing malware.

Questions about .kyra file extension virus

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 or using 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.

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.
