OXAR Ransomware – Infection

OXAR ransomware could spread its infection with various methods. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your PC will become infected. You can see the detections of such a file on the VirusTotal service right here:

OXAR ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. You should read the tips for preventing ransomware found in our forums.

OXAR Ransomware – In-Depth Look

OXAR is a virus that could encrypt your files and extort you to pay a ransom to get them back to normal. Malware researchers have discovered that it is a variant of the HiddenTear open-source project and also developed with Visual Studio 2017.

OXAR ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

You can see the ransom note that is placed in your computer system after the encryption process is completed:

That ransom note reads the following:

LOCKED IN
Files successfully encrypted !
What Happened to My Computer?
Your important files are encrypted.
Many of your documents, photos, videos, databases and other files are no longer accessible because they have been encrypted. Maybe you are busy looking for a way to recover your files, but do not waste your time. Nobody can recover your files without our decryption service.

But if you want to decrypt all your files, you need to pay.

We strongly recommend you to not remove this software, and disable your anti-virus for a while, until you pay and the payment gets processed. If your anti-virus gets updated and removes this software automatically, it will not be able to recover your files even if you pay!
Do not modify the “.OXR” extension of your encrypted files, it will become unrecoverable

Step two:
Buy 100$ USD https://blockchain.info/fr/wallet/#/buy-sell

Your working documents, holiday photos, children, videos, and all your valuable documents have been encrypted with a powerful encryption algorithm, follow the instructions given to retrieve the encryption key

The note of the OXAR ransomware states that your files are encrypted. The ransom sum of 100 US dollars is demanded to be paid in Bitcoins for potentially unlocking your files. However, you should NOT under any circumstances pay that ransom. Your files may not get restored, and nobody could give you a guarantee for that. Moreover, giving money to cybercriminals will likely motivate them to create more ransomware viruses or get involved in more serious criminal acts.

OXAR Ransomware – Encryption

The OXAR ransomware is a HiddenTear variant but it encrypts files with the following extensions:

→.aif, .apk, .arj, .asp, .bat, .bin, .cab, .cda, .cer, .cfg, .cfm, .cpl, .css, .csv, .cur, .dat, .deb, .dmg, .dmp, .doc, .docx, .drv, .gif, .htm, .html, .icns, .iso, .jar, .jpeg, .jpg, .jsp, .log, .mid, .mp3, .mp4, .mpa, .odp, .ods, .odt, .ogg,.part, .pdf, .php, .pkg, .png, .ppt, .pptx, .psd, .rar, .rpm, .rss, .rtf, .sql, .svg, .tar.gz, .tex, .tif, .tiff, .toast, .txt, .vcd, .wav, .wks, .wma, .wpd, .wpl, .wps, .wsf, .xlr, .xls, .xlsx, .zip

Every single file that gets encrypted will receive the same extension appended to it, which is .OXR. The encryption algorithm which is implemented is undoubtedly AES since it is a HiddenTear variant, but that doesn’t completely exclude the possibility of involving another encrypting algorithm in the mix in the near future.

The OXAR cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

If the above-stated command is indeed inputted into your computer, it will delete the Windows copies made for the Recovery feature deeming it unfit to work or recover your files back to the way they were before the infection. If your personal computer was infected with this ransomware and your files are now locked, read on through to find out how you could potentially restore your files.
