WHOLE Ransomware 🔐 (.WHOLE File) — Removal Guide

The Whole virus belongs to the ransomware type of infection. Malware of this type encrypts all the data on your PC (photos, documents, excel sheets, audio files, videos, etc) and appends its specific extension to every file, leaving the README-ID-[victim\’s_ID].txt text files in every directory which contains the encrypted files.

What is Whole virus?

Whole will add its own .whole extension to every file’s name. For instance, an image named “photo.jpg” will be changed to “photo.jpg.whole”. Just like the Excel table named “table.xlsx” will be renamed to “table.xlsx.whole”, and so on.

In each directory with the encrypted files, a README-ID-[victim\’s_ID].txt text document will be found. It is a ransom money memo. Therein you can find information on the ways of contacting the racketeers and some other remarks. The ransom note most probably contains instructions on how to buy the decryption tool from the Whole developers. You can get this decryptor after contacting [email protected] via email. That is how they do it.

In the picture below, you can see what a directory with files encrypted by the Whole looks like. Each filename has the “.whole” extension appended to it.

How did Whole ransomware end up on my PC?

There are many possible ways of ransomware infiltration.

Nowadays, there are three most exploited methods for malefactors to have ransomware planted in your system. These are email spam, Trojan injection and peer-to-peer file transfer.

  • Another option for ransom hunters is a Trojan horse model. A Trojan is a program that infiltrates into your computer pretending to be something else. For example, you download an installer of some program you need or an update for some program. However, what is unpacked reveals itself a harmful program that compromises your data. As the installation wizard can have any title and any icon, you have to make sure that you can trust the resource of the things you’re downloading. The optimal thing is to use the software companies’ official websites.
  • As for the peer-to-peer networks like BitTorrent or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is reasonable to scan the folder containing the downloaded files 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 Whole virus will probably deploy Vidar Stealer on your computer to seize your credentials to various accounts (including cryptocurrency wallets). That spyware can extract your logins and passwords from your browser’s auto-filling cardfile.

How to avert ransomware attack?

Whole ransomware has no superpower, neither does any similar malware.

You can protect your computer from its attack in three easy steps:

  • Never open any letters from unknown senders with unknown addresses, or with content that has nothing to do with something you are expecting (can you win in a money prize draw without even taking part in it?). If the email subject is more or less something you are expecting, scrutinize all elements of the suspicious letter carefully. A fake email will always contain a mistake.
  • Do not use cracked or untrusted software. Trojan viruses are often shared as an element of cracked software, most likely under the guise of “patch” preventing the license check. Understandably, potentially dangerous programs are very hard to tell from reliable ones, as trojans sometimes have the functionality you seek. You can try searching for information about this program on the anti-malware forums, but the optimal way is not to use such programs at all.

FAQ

🤔 How can I open “.whole” files?Can I somehow access “.whole” files?

Negative. That is why ransomware is so frustrating. Until you decode the “.whole” files you will not be able to access them.

🤔 What should I do to make my files accessible as fast as possible?

If the “.whole” files contain some really important information, then you probably have them backed up. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. There are other ways to beat ransomware, but they take time.

🤔 What should I do if the Whole ransomware has blocked my PC and I can’t get the activation key.

🤔 What can I do right now?

Some of the encrypted data can be found elsewhere.

  • If you exchanged your critical files through email, you could still download them from your online mailbox.
  • You may have shared photographs or videos with your friends or relatives. Simply ask them to send those pictures back to you.
  • If you have initially downloaded 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, external storage, etc.

HINT: You can employ file recovery utilities1 to retrieve your lost information since ransomware encrypts the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to recover your files with PhotoRec, but be advised: you can do it only after you remove the ransomware itself with an antivirus program.
