[TOX].GUCCI Virus — How to Fix GUCCI Ransomware?

Safety specialist Tomas Meskauskas was the person who, for the first time, revealed the Tox gucci virus, which falls within the ransomware type of malicious agent. Malware of this type encrypts all user’s data on the computer (images, documents, excel tables, audio files, videos, etc) and appends its specific extension to every file.

What is Tox gucci virus?

☝️ A strictly accurate designation for the Tox gucci is “a ransomware-type malicious agent”.

The pattern of renaming is this: GUCCI. In the process of encryption, a file named, for instance, “report.docx” will be changed to “report.docx.id[9ECFA84E-3208].[tox].GUCCI”.

The ransom note usually contains a description of how to purchase the decryption tool from the tamperers. That is how they do it.

How did Tox gucci ransomware end up on my PC?

There are many possible ways of ransomware injection.

Nowadays, there are three most exploited ways for criminals to have the Tox gucci virus acting in your system. These are email spam, Trojan infiltration and peer-to-peer networks.

If you access your inbox and see letters that look like familiar notifications from utility services companies, postal agencies like FedEx, web-access providers, and whatnot, but whose “from” field is strange to you, beware of opening those emails. They are very likely to have a ransomware item enclosed in them. So it is even riskier to download any attachments that come with emails like these.

As for the peer-to-peer networks like BitTorrent or eMule, the danger 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 a good idea to scan the directory containing the downloaded items with the anti-malware utility as soon as the downloading is done.

How to remove the Tox gucci virus?

It is crucial to inform you that besides encrypting your data, the Tox gucci virus will most likely deploy the Azorult Spyware on your PC to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned program can extract your logins and passwords from your browser’s auto-filling cardfile.

Sometimes racketeers would decrypt few of your files to prove that they really have the decryption program. Since Tox gucci virus is a relatively new ransomware, security software designers have not yet found a way to undo its work. Nevertheless, the anti-ransomware tools are frequently updated, so the solution may soon arrive.

Understandably, if the malefactors do the job of encrypting someone’s critical files, the desperate person will probably comply with their demands. Nevertheless, paying a ransom does not necessarily mean that you’re getting your data back. It is still dangerous. After receiving the money, the racketeers may send a wrong decryption key to the victim. There were reports about criminals just disappearing after getting the money without even bothering to reply.

The optimal safety measure against ransomware is to have aan OS restore point or the copies of your critical files in the cloud drive or at least on an external disk. Of course, that might be not enough. The most important thing could be that file you were working upon when it all started. Nevertheless, it is something. It is also reasonable to scan your drives with the antivirus program after the system restoration.

There are other ransomware products, besides Tox gucci, that work similarly. For instance, Jhdd, Tuid, Ghas, and some others. The two major differences between them and the Tox gucci are the ransom amount and the encoding method. The rest is the same: documents become inaccessible, their extensions changed, ransom notes appear in each directory containing encoded files.

Some fortunate people were able to decrypt the arrested files with the help of the free tools provided by anti-ransomware developers. Sometimes the criminals accidentally send the decoding key to the wronged in the ransom note. Such an extraordinary fail allows the victim to restore the files. But naturally, one should never rely on such a chance. Make no mistake, ransomware is a criminals’ technology to lay their hands on the money of their victims.

How сan I avert ransomware attack?

Tox gucci ransomware doesn’t have a superpower, so as any similar malware.

You can protect your computer from ransomware infiltration in three easy steps:

  • Never open any letters from unknown senders with strange addresses, or with content that has likely no connection to something you are expecting (can you win in a lottery without even taking part in it?). If the email subject is more or less something you are expecting, check all elements of the dubious email carefully. A hoax letter will always contain mistakes.
  • Never use cracked or untrusted programs. Trojan viruses are often distributed as a part of cracked products, most likely under the guise of “patch” to prevent the license check. But potentially dangerous programs are difficult to distinguish from trustworthy software, because trojans sometimes have the functionality you seek. You can try to find information on this software product on the anti-malware message boards, but the best solution is not to use such software.

FAQ

🤔 Can I somehow access “.GUCCI” files?

Unfortunately, no. You need to decipher the “.GUCCI” files first. Then you will be able to open them.

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

Hopefully, you have made a copy of those important files. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. All other solutions require time.

🤔 What should I do if the Tox gucci ransomware has blocked my computer and I can’t get the activation key.

🤔 What could help the situation right now?

Some of the blocked data can be found elsewhere.

  • If you exchanged your important files through email, you could still download them from your online mail server.
  • You might have shared images or videos with your friends or family members. Just ask them to send those pictures back to you.
  • If you have initially got any of your files from the Web, 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 computer, a notebook, cellphone, external storage, etc.

HINT: You can use file recovery programs4 to retrieve your lost information since ransomware arrests the copies of your files, deleting the authentic ones. In the video below, you can learn how to recover your files with PhotoRec, but be advised: you can do it only after you kill the ransomware itself with an anti-malware program.

Also, you can contact the following governmental fraud and scam sites to report this attack:

To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
