May Ransomware – Description

May is a virus that will encrypt your files and try to extort you to pay a ransom to get them restored. Malware researchers have found it a few days ago in the middle of month May, so its name is appropriate.

May ransomware could make entries in the Windows Registry to achieve persistence, and probably 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.

The note is written in English, and it will be inside a file called Restore_your_files.txt. You can view the ransom message that loads after the encryption process in this picture:

That ransom note stored in the Restore_your_files.txt file reads the following:

You have 5 days for decrypt your files.
All your files have been encrypted with May Ransomware.
For encrypt we use AES256+RSA4096.
Don`t try recover your files.
Decrypt instruction!
1) Make your bitcoin wallet on block.io or blockchain.info and buy 1 bitcoins on BTC Exchange Sites (https://goo.gl/1PE96T)
2) Send 1 bitcoin to address 3Gw6b57A3E34nAph3mzGbKAj8sTSgD8GP9
3) Write to us on email [email protected] . In subject write this identificator “81ff05bf2ab1406d8f11b866e804af37”
4) After receive bitcoins and your email , we contact with you.
YOU MIGHT DECRYPT 2 FILES FOR FREE. Send it to email [email protected] .In Subject ,write your UNIQUE Identificator.

The ransomware gives you a period of 5 days to make the demanded payment of 1 Bitcoin. That amount equals to nearly 1.833 US dollars, at the moment of writing of this article.
You should NOT under any circumstances pay the ransom. Your files may not get restored, and nobody could give you any real guarantee. Moreover, giving money to cybercriminals will likely motivate them to create more ransomware viruses or even do different criminal activities.

May Ransomware – Encryption Process

Currently, the ransomware is still being researched, and some experts say that it might be a HiddenTear variant, while others don’t say such a thing. If that proves to be true, then the encryption algorithm will probably be AES. Although, the ransom note states that the encryption algorithms which are used are AES 256-bit and RSA 4096-bit ones. For now, there is no information about what extensions the cryptovirus seeks to encrypt. However, most probably extensions for the following file types are being encrypted:

  • Text
  • Image
  • Video
  • Music
  • Database

Those file types are still the most commonly-used ones today for nearly all Windows users, making the list quite viable. All of the files that get encrypted will receive the same extension appended to them, and that is the .locked extension.

The May cryptovirus might be tweaked 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

In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your files. If your computer is infected with this ransomware, read on through to find out how you could potentially recover your files.
