The 7ev3n ransomware may be delivered through several channels. One of them is via spam emails containing malicious email attachments. If you open such an attachment, the malware is set free.

Most commonly it is disguised as a useful application, needed update or something similar. Visiting untrusted sites and redirects may lead to malware.

7ev3n Ransomware – Technical Information

7ev3n is classified as a ransomware virus. When it is on your computer, before starting the encryption process, it first performs other malicious actions. First a Trojan is put usually under the name UAC.exe, along with A13-1.exe and System.exe. For persistence and running with each start of Windows, it creates the following two registry values in the Windows Registry, both tied with the System.exe file:

→HKLM/Software/Microsoft/Windows/CurrentVersion/Run/

and

→HKLM/Software/Microsoft/WindowsNT/CurrentVersion/Winlogon/Shell

Then, 7ev3n spreads multiple text file copies of the ransom message.

Here is what the ransom message states:

1. Pay amount of 13 bitcoin (approximately 4980 USD) to address: bitcoin address, this unique address generated only for you.

This is not a complete list as there might be other file extensions that are encrypted. It changes the file extension of all encrypted files to .r5a.

The 7ev3n ransomware demands a really high sum of money for decryption compared to many different ransomware types. As you can see from the ransom note, 13 BitCoins is a lot. Now, as this article is being written, that is around 5140 dollars. In the ransom note, there are even examples being given from where to buy BitCoins.
