7ev3n Ransomware – Delivery
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. Malicious code may be hidden inside the sole body of the email, so just by opening such an email, you can get infected, even without clicking on an attachment.
Other channels for delivery are social networks and file sharing services, which may have similar attachments and files containing the 7ev3n ransomware. 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:
YOUR PERSONAL INFORMATION ARE ENCRYPTED by 7ev3n
All your documents, photos, databases, office projects and other important files have been encrypted with strongest encryption algorithm and unique key, original files have been overwritten, recovery tools and software will not help. Private key is stored on a server and nobody can decrypt your files until you pay and obtain the private key.
You have only 96 hours to make a payment. If you do not send money within provided time, private key will be destroyed, and all your files will be lost. Follow the instructions:
1. Pay amount of 13 bitcoin (approximately 4980 USD) to address: bitcoin address, this unique address generated only for you.
2. Transaction will take about 50 minutes to accept and confirm the payment, decryption and uninstalling of this software will start automatically. For correct key and decryption, DO NOT: power off computer, disable Internet connection, run antivirus program. Usually decryption will take about 1-3 hours, average decrypt speed 21gb per hour.
Bitcoin is a digital currently that you can buy on ‘eBay.com’, ‘localbitcoins.com’, ‘anxpro.com’, ‘ccedk.com’ and many other online and physical exchangers through credit card, bank account, using PayPal and many other payment methods.
Warning, do not try to get rid of this program, any action taken will result in decryption key being destroyed, you will lose your files forever, one way to get you files os to follow that instructions. In case of non-payment reserve the right to publicly publish all encrypted files.
Afterward, 7ev3n ransomware is known to search for and encrypt files with these extensions:
→ .doc, .txt, .xls, .xlsx, .xml, .docx, .html, .jpg, .js, .mdb, .odt, .pdf, .php, .png, .ppt, .pptx, .sql
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. We strongly advise you NOT to pay as there is absolutely no guarantee that you will receive a decryption key, let alone a working one.
