The Snet virus falls under the ransomware type of infection. Ransomware of this type encrypts all user’s data on the computer (images, documents, excel sheets, music, videos, etc) and appends its extra extension to every file, creating the DecryptNote.txt files in each folder with the encrypted files.
What is known about the Snet virus?
Snet appends its extra .SNet extension to the name of every encoded file. For instance, a file named “photo.jpg” will be altered to “photo.jpg.SNet”. In the same manner, the Excel sheet with the name “table.xlsx” will be renamed to “table.xlsx.SNet”, and so on.
In each directory with the encoded files, a DecryptNote.txt text file will be created. It is a ransom money memo. It contains information on the ways of paying the ransom and some other remarks. The ransom note most probably contains instructions on how to purchase the decryption tool from the tamperers. You can get this tool after contacting [email protected] via email. That is pretty much the scheme of the crime.

The DecryptNote.txt file coming in package with the Snet malware provides the following dispiriting information:
Your Decryption ID: - Your files are encrypted and We have stored your data on our servers, including documents, databases, and other files, and if you don\'t contact us, we\'ll extract your sensitive data and leak them. Trust us, we know what data we should gather. However, if you want your files returned and your data is secure from leaking, contact us at the following email addresses: [email protected] [email protected] (Remember, if we don\'t hear from you for a while, we will start leaking data) >>>> What is the guarantee that we won\'t trick you? You can send us two random small files in any format, We will decrypt them for free and return it to you as a guarantee. After you pay, we will send you decryption software and wipe all of your data. Nobody will pay us in the future if we do not provide you with the decrypters or if we do not remove your data after receiving payment. We have no political goals and are not trying to harm your reputation. This is our business. Money and our reputation are the only things that matter to us. We attack businesses all throughout the world, and there has never been an unhappy victim after payment.
In the screenshot below, you can see what a folder with files encrypted by the Snet looks like. Each filename has the “.SNet” extension appended to it.
How did my computer get infected with Snet ransomware?
There is a huge number of possible ways of ransomware injection.
Nowadays, there are three most popular methods for hackers to have ransomware acting in your digital environment. These are email spam, Trojan injection and peer-to-peer networks.
- If you open your inbox and see emails that look just like notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose “from” field is strange to you, be wary of opening those emails. They are most likely to have a harmful file attached to them. Thus it is even more dangerous to open any attachments that come with letters like these.
- Another option for ransom hunters is a Trojan virus scheme. A Trojan is an object that gets into your PC pretending to be something else. For instance, you download an installer of some program you need or an update for some service. However, what is unboxed reveals itself a harmful program that corrupts your data. As the update package can have any name and any icon, you’d better be sure that you can trust the resource of the files you’re downloading. The optimal way is to use the software developers’ official websites.
- As for the peer file transfer protocols like BitTorrent or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the folder containing the downloaded items with the anti-malware utility as soon as the downloading is done.
How to remove ransomware?
It is important to inform you that besides encrypting your data, the Snet virus will most likely install Vidar Stealer on your machine to seize your credentials to various accounts (including cryptocurrency wallets). The mentioned spyware can derive your logins and passwords from your browser’s auto-filling cardfile.
How to avoid ransomware infiltration?
Snet ransomware has no endless power, so as any similar malware.
You can armour your PC from its infiltration in several easy steps:
- Ignore any emails from unknown mailers with unknown addresses, or with content that has nothing to do with something you are expecting (how can you win in a lottery without participating in it?). If the email subject is likely something you are expecting, scrutinize all elements of the questionable letter with caution. A fake letter will surely contain mistakes.
- Avoid using cracked or untrusted programs. Trojans are often distributed as a part of cracked products, possibly under the guise of “patch” preventing the license check. Understandably, dubious programs are very hard to distinguish from reliable ones, because trojans may also have the functionality you seek. You can try searching for information about this software product on the anti-malware message boards, but the best way is not to use such programs at all.
Frequently Asked Questions
🤔 How can I open “.SNet” files?Is it possible to open“.SNet” files?
Negative. That is why ransomware is so frustrating. Until you decode the “.SNet” files you will not be able to access them.
🤔 I really need to decrypt those “.SNet” files ASAP. How can I do that?
If the “.SNet” files contain some really important information, then you probably have them backed up. In case you haven’t, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. There are other ways to beat ransomware, but they take time.
🤔 What to do if the Snet malware has blocked my computer and I can’t get the activation key.
🤔 And what should I do now?
Many of the encoded files might still be at your disposal
- If you sent or received your critical files through email, you could still download them from your online mail server.
- You might have shared photographs or videos with your friends or family members. Just ask them to post those images back to you.
- If you have initially got any of your files from the Internet, you can try downloading them again.
- Your messengers, social networks pages, and cloud disks might have all those files too.
- It might be that you still have the needed files on your old PC, a laptop, mobile, memory stick, etc.
HINT: You can employ file recovery programs1 to get your lost data back since ransomware arrests the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to recover your files with PhotoRec, but remember: you can do it only after you remove the virus with an antivirus program.
