What is yG ransomware? And how does it execute its attack?

yG ransomware is a new file-encrypting virus designed to take over a compromised computer to encrypt files. According to researchers, this ransomware is a variant of the Dharma ransomware family which already has a number of variants that carry out similar attacks.

yG Ransomware

Once it successfully infects your computer, yG ransomware connects to its Command and Control server to deliver information about the infected PC, and then in return, it receives the necessary data to carry out the encryption process. Before the encryption, it scans the computer for important files with different file types such as photos, music, videos, databases, texts, configuration files, archives, spreadsheets and a whole lot more and then encrypts them using the RSA 1024 encryption algorithm.

All the targeted files are marked with [[email protected]].yG extension which is added at the end of each file’s name. Once it is done with the encryption, it delivers a ransom note which is contained in a text file named [email protected], and places it on the desktop. The ransom note reads as follows:

“All FILES ENCRYPTED “RSA1024”
All YOUR FILES HAVE BEEN ENCRYPTED!!! IF YOU WANT TO RESTORE THEM, WRITE US TO THE E-MAIL [email protected]
IN THE LETTER WRITE YOUR ID, YOUR ID ***
IF YOU ARE NOT ANSWERED, WRITE TO EMAIL: [email protected]
YOUR SECRET KEY WILL BE STORED ON A SERVER 7 DAYS, AFTER 7 DAYS IT MAY BE OVERWRITTEN BY OTHER KEYS, DON’T PULL TIME, WAITING FOR YOUR EMAIL
FREE DECRYPTION FOR PROOF
You can send us up to 1 file for free decryption. The total size of files must be less than 1Mb (nonarchived), and files should not contain valuable information. (databases, backups, large excel sheets, etc.)
DECRYPTION PROCESS:
When you make sure of decryption possibility transfer the money to our bitcoin wallet. As soon as we receive the money we will send you:

  1. Decryption program.
  2. Detailed instruction for decryption.
  3. And individual keys for decrypting your files.

!WARNING!
Do not rename encrypted files.
Do not try to decrypt your data using third-party software, it may cause permanent data loss.
The decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.”

How is the payload file of yG ransomware disseminated online?

yG ransomware’s distribution method is quite unclear since its infections rate is not that high. But according to our specialists, its distribution technique should not differ from other malware which means that, just like most ransomware infections, yG’s malicious files are spread using spam email campaigns. It is one of the most popular ransomware distributions among this type of infection. Aside from that, it can also spread its infection on third-party pages that present themselves as P2P websites. These kinds of websites contain not just ransomware viruses but also other kinds of computer parasites.
