The Byee virus belongs under the ransomware type of malicious agent. Malware of this type encrypts all user’s data on the computer (photos, text files, excel sheets, music, videos, etc) and appends its specific extension to every file, creating the read_it-EC.txt text files in every directory which contains the encrypted files.
What is known about the Byee virus?
Byee appends its extra .byee extension to the name of each encoded file. For example, a file named “photo.jpg” will be altered to “photo.jpg.byee”. In the same manner, the Excel table with the name “table.xlsx” will be renamed to “table.xlsx.byee”, and so forth.
In each directory that contains the encoded files, a read_it-EC.txt file will appear. It is a ransom money memo. It contains information about the ways of paying the ransom and some other remarks. The ransom note usually contains instructions on how to buy the decryption tool from the racketeers. You can get this decrypting software after contacting Telegram contact through email. That is basically the scheme of the malefaction.

Don\'t worry, you can Return all your files! All your files like documents, photos, databases and other are encrypted To Contact Telegram : - Have Good Day!
In the image below, you can see what a folder with files encrypted by the Byee looks like. Each filename has the “.byee” extension added to it.
How did Byee ransomware end up on my PC?
There are plenty of possible ways of ransomware injection.
There are currently three most exploited methods for tamperers to have the Byee virus acting in your digital environment. These are email spam, Trojan introduction and peer-to-peer file transfer.
- Another option for ransom hunters is a Trojan file scheme. A Trojan is an object that gets into your machine pretending to be something legal. Imagine, you download an installer for some program you need or an update for some software. However, what is unboxed reveals itself a harmful agent that encodes your data. Since the installation file can have any title and any icon, you’d better be sure that you can trust the source of the stuff you’re downloading. The optimal thing is to use the software developers’ official websites.
- As for the peer-to-peer networks like torrent trackers or eMule, the danger 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 resources. Also, it is reasonable to scan the folder containing the downloaded items with the antivirus as soon as the downloading is complete.
How to remove ransomware?
It is crucial to note that besides encrypting your data, the Byee virus will most likely deploy Vidar Stealer on your machine to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned program can derive your logins and passwords from your browser’s auto-filling data.
How сan I avoid ransomware attack?
Byee ransomware doesn’t have a superpower, so as any similar malware.
You can defend your system from ransomware infiltration in three easy steps:
- Never open any letters from unknown senders with strange addresses, or with content that has nothing to do with something you are waiting for (can you win in a lottery without even taking part in it?). If the email subject is likely something you are expecting, scrutinize all elements of the questionable letter with caution. A hoax email will always contain a mistake.
- Avoid using cracked or unknown programs. Trojans are often distributed as a part of cracked software, possibly as a “patch” which prevents the license check. But potentially dangerous programs are difficult to tell from reliable software, as trojans may also have the functionality you need. Try searching for information on this program on the anti-malware message boards, but the best solution is not to use such software.

HINT: You can employ data recovery programs1 to get your lost data back since ransomware blocks the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to use PhotoRec for such a restoration, but remember: you won’t be able to do it before you remove the virus with an antivirus program.
