YG ransomware (Free Instructions) - Decryption Steps Included

What is yG ransomware?

yG ransomware is the virus that encrypts files using RSA algorithm and marks encoded data using [sysadmin@mail.fr].yG appendix

yG ransomware virus is the crypto-extortion based malware that hails from a well-known Dharma/Crysis ransomware family.

yG ransomware is the cryptovirus that tries to seem trustworthy, so offers test decryption for proving that. Unfortunately, victims that decide to pay the demanded ransom have only a week to do so, after that, ransomware will get rid of the needed decryption keys. This information is stated in the ransom note that appears on the screen after the initial encryption process. As usual for other Dharma ransomware versions, the message comes in the form of program window named with the sysadmin@mail.fr email address. This is only one of many versions in the virus family recently discovered by Jakub Kroustek, one of the malware researchers who reports about this cryptovirus family almost daily.

This file-locking virus is focusing on getting money, so we don't recommend contacting yG ransomware virus developers because there are more reports about lost data and money than reports on successful data recovery after paying.^[1] Although this threat affects you important data, focus on malware termination, and then worry about the data recovery.

yG ransomware is one of many new variants of Dharma/Crysis that is known for a while now but developers releasing versions every week. The category of ransomware is one of the most dangerous because this type of malware involves damaging data and extorting money from victims.

Getting cryptocurrency is the main goal of yG ransomware virus developers, so they are not concerned about your files. Recently, such threats targeted bigger companies and even governments to make more profit from one victim since the ransom amount, in these attacks can differ from thousands to hundreds of thousands of dollars.^[2]

In this case, when yG ransomware targets everyday PC users, the amount can be set to each victim individually, based on the number of encrypted files or the value of these files. The ransomware attack starts with a system scan when data in particular formats get chosen for the encryption process. In most cases, ransomware encrypts:

• photos;
• videos;
• audio files;
• documents;
• databases;
• archives.

Unfortunately, people may store their login information, passwords or different account credentials on the system and when such malware like yG ransomware checks the machine it can steal those credentials and use them for identity theft or in later scams. So react to the ransom note and encryption process by getting an anti-malware program as soon as possible and cleaning the computer.

yG ransomware is the threat that encrypts files on the computer and demands the ransom while promising to recover those files. These people are cybercriminals and they shouldn't be trusted.

yG ransomware virus also changes parts of the system by disabling programs, functions and deleting files from the computer. All those alterations, when made affects the virus elimination significantly and makes ransomware more persistent. The malware can also delete Shadow Volume Copies to make data recovery difficult.

The extortionists want you to believe their claims about the decryption and pay the demanded ransom, but paying is not the solution for yG ransomware removal because during the communication with criminals they can send you more malicious files or require more money in the future.

Experts^[3] always note that cryptovirus may encode files again to make them damaged or affect data you recovered. When .yG virus remains running on the system, it finds various data and encrypts them in addition to the first file-locking. Cleaning the computer thoroughly first ensures that restored files cannot get damaged. We have a few methods listed below for data recovery.

Ransomware gets distributed via spam emails containing infected attachments

Various system vulnerabilities can be exploited to infiltrate the targeted system. However, the primary technique used to spread such threats like cryptovirus is phishing email campaigns during which legitimate-looking notifications with infected attachments deliver malicious scripts or even direct ransomware on the PC.

Emails with forged header information trick users into believing that it is from a service or company like DHL or eBay. Information about the failed delivery or packages that cannot get shipped to you should be in the attached document. Once you download and open that word or PDF document, malicious macros get triggered, and payload droppers launched.

You should resist being curious and don't open the attached file or click on the link included on the email or the document. Every time you receive the email you were not expecting to get, try to look out for red flags like typos or grammar mistakes and senders you are not familiar with. Delete suspicious emails without opening them.
