GUCCI ransomware (virus) - Recovery Instructions Included

GUCCI virus Removal Guide

What is GUCCI ransomware?

GUCCI ransomware can permanently damage users' personal files and the operating system

GUCCI ransomwareGUCCI ransomware locks users' data making it impossible to access

GUCCI ransomware is one of the most recent data-locking malware variants that belong to the Phobos ransomware family. The file was flagged by 54 security vendors and 3 sandboxes as malicious. The virus can enter the system and start the encryption process immediately.

Once it starts, all personal files, like photos, videos, and documents get encrypted. It means that they become inaccessible and unusable. The only way to decrypt the data is with a decryption key[1] or software, which usually only the cybercriminals have.

After the encryption process is done, the icons of the files turn to white pages and the names get appended with the .GUCCI extension. For example, if a file was previously named picture.jpg, after completion, the same file would be named picture.jpg.id[victim-id].[tox].GUCCI.

Two ransom notes get generated on the machine as well. These messages from the ransomware developers explain to victims what happened and what they need to do to recover their files. Unfortunately, threat actors blackmail users by asking for payment in cryptocurrencies.[2]

Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.
We also want to notify you that the most important data of your company was copied by us, but we guarantee the confidentiality of private information and information about this incident in case of successful cooperation. Otherwise, we reserve the right to monetize our services by selling your information at specialized auctions.

info.hta ransom noteThe attackers created a lengthy ransom note asking victims for payment

The attackers create a sense of urgency by saying that the amount to be paid to them depends on how fast the victims contact them. This is one of many scare tactics that cybercriminals use to make people act quickly without thinking about other options. That is why also the ransom amount is not specified in the note.

They also offer to decrypt one file for free to make them look more trustworthy. However, you should remember that criminals cannot be trusted. Many previous ransomware attack victims have come forward and said that they never heard back from the perpetrators after they paid the money.

Their payment method is also not very advantageous to the victims. Cryptocurrency transactions are anonymous, and they are impossible to reverse. Once people send the funds, it is impossible to get a refund or get them back some other way. That is why by paying the ransomware developers you do not only risk losing your files but getting scammed too.

Crooks also try to prevent people from looking for other recovery options by using intimidation tactics. Although third-party decryption tools rarely help it is worth at least trying. The other ransom note info.txt is just a shorter version of the previous message:

!!!All of your files are encrypted!!!

Use professional security tools to eliminate malicious files

The thing that you have to do immediately is to disconnect the affected machine from the local network. For home users, disconnecting the ethernet cable or disabling the Wi-Fi should do the job. If this happened at your workplace, doing that might be complicated, so we have separate instructions for you at the bottom of this post.

If you try to recover your data first, it can result in permanent loss. Malware can also encrypt your files the second time if it is not eliminated first. It will not stop until you remove the malicious files causing it. You should not attempt removing the malicious program yourself unless you have excellent IT skills.

Use anti-malware tools like SpyHunter 5Combo Cleaner or Malwarebytes to scan your system. This security software should find all the related files and entries and remove them automatically for you. In some cases, malware can prevent you from using antivirus software, so you need to access Safe Mode and perform a full system scan from there:

Windows 7 / Vista / XP

  1. Click Start > Shutdown > Restart > OK.
  2. When your computer becomes active, start pressing the F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
  3. Select Safe Mode with Networking from the list.

Windows 10 / Windows 8

  1. Right-click on the Start button and select Settings.
  2. Scroll down to pick Update & Security.
  3. On the left side of the window, pick Recovery.
  4. Now scroll down to find the Advanced Startup section.
  5. Click Restart now.
  6. Select Troubleshoot.
  7. Go to Advanced options.
  8. Select Startup Settings.
  9. Click Restart.
  10. Press 5 or click 5) Enable Safe Mode with Networking.

Fix system errors to prevent Windows reinstallation

Performance, stability, and usability issues, to the point where a complete Windows reinstall is required, are expected after malware infection. These types of viruses can alter the Windows registry database, damage vital bootup, and other functions, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software will not able to repair it.

This is why ReimageIntego was developed. This powerful software can fix a lot of the damage caused by GUCCI ransomware. Blue Screen errors,[3] freezes, registry errors, damaged DLLs, etc., can make your computer completely unusable. By using this maintenance tool, you could avoid Windows reinstallation.

  • Download the application by clicking on the link above
  • Click on the ReimageRepair.exe
  • If User Account Control (UAC) shows up, select Yes
  • Press Install and wait till the program finishes the installation process
  • The analysis of your machine will begin immediately
  • Once complete, check the results – they will be listed in the Summary
  • You can now click on each of the issues and fix them manually
  • If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.Reimage results

File recovery options

Many people think that they can fix their files with anti-malware tools, but that is not what they are designed for. All the security tools can do is detect suspicious processes in your system and eliminate them. The truth is, the files can be restored only with a decryption key or software that only the cybercriminals have.

If you did not back up your data previously, it might be possible that you will never get them back. You can try using data recovery software, but we have to note that third-party programs cannot always decrypt the files. We suggest at least trying this method. Before proceeding, you have to copy the corrupted files and place them in a USB flash drive or another storage. And remember – only do this if you have already removed the GUCCI ransomware.

Before you begin, several pointers are essential while dealing with this situation:

  • Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
  • Only attempt to recover your files using this method after you perform a scan with anti-malware software.

Install data recovery software

  1. Download Data Recovery Pro.
  2. Double-click the installer to launch it.
  3. Follow on-screen instructions to install the software.Install program
  4. As soon as you press Finish, you can use the app.
  5. Select Everything or pick individual folders where you want the files to be recovered from.Select what to recover
  6. Press Next.
  7. At the bottom, enable Deep scan and pick which Disks you want to be scanned.Select Deep scan
  8. Press Scan and wait till it is complete.
  9. You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
  10. Press Recover to retrieve your files.Recover files

Ransomware distribution methods

In order to protect yourself from future ransomware attacks, it is important to know how this dangerous malware usually spreads. The most common gateways are torrent sites, peer-to-peer file-sharing platforms, and “cracked” software[4] installations. It is best to use only official web stores and developer sites whenever you want to download new software.

Another preferred method is email. Cybercriminals can add infected attachments to the emails. Usually, they use social engineering[5] methods to make people open them. So never open any email attachments unless it is from someone you know or you are sure that it is from a trustworthy sender.

You should also remember that it is extremely important to keep your operating system and software up-to-date. Developers often release not only updates but security patches of newly found vulnerabilities. Hackers love to exploit vulnerabilities so as soon as new updates are available, make sure to install them.

Getting rid of GUCCI virus. Follow these steps

Isolate the infected computer

Some ransomware strains aim to infect not only one computer but hijack the entire network. As soon as one of the machines is infected, malware can spread via network and encrypt files everywhere else, including Network Attached Storage (NAS) devices. If your computer is connected to a network, it is important to isolate it to prevent re-infection after ransomware removal is complete.

The easiest way to disconnect a PC from everything is simply to plug out the ethernet cable. However, in the corporate environment, this might be extremely difficult to do (also would take a long time). The method below will disconnect from all the networks, including local and the internet, isolating each of the machines involved.

  • Type in Control Panel in Windows search and press Enter
  • Go to Network and Internet Network and internet
  • Click Network and Sharing Center Network and internet 2
  • On the left, pick Change adapter settings Network and internet 3
  • Right-click on your connection (for example, Ethernet), and select Disable Network and internet 4
  • Confirm with Yes.

If you are using some type of cloud storage you are connected to, you should disconnect from it immediately. It is also advisable to disconnect all the external devices, such as USB flash sticks, external HDDs, etc. Once the malware elimination process is finished, you can connect your computers to the network and internet, as explained above, but by pressing Enable instead.

Find a working decryptor for your files

File encryption is a process that is similar to applying a password to a particular file or folder. However, from a technical point of view, encryption is fundamentally different due to its complexity. By using encryption, threat actors use a unique set of alphanumeric characters as a password that can not easily be deciphered if the process is performed correctly.

There are several algorithms that can be used to lock data (whether for good or bad reasons); for example, AES uses the symmetric method of encryption, meaning that the key used to lock and unlock files is the same. Unfortunately, it is only accessible to the attackers who hold it on a remote server – they ask for a payment in exchange for it. This simple principle is what allows ransomware authors to prosper in this illegal business.

While many high-profile ransomware strains such as Djvu or Dharma use immaculate encryption methods, there are plenty of failures that can be observed within the code of some novice malware developers. For example, the keys could be stored locally, which would allow users to regain access to their files without paying. In some cases, ransomware does not even encrypt files due to bugs, although victims might believe the opposite due to the ransom note that shows up right after the infection and data encryption is completed.

Therefore, regardless of which crypto-malware affects your files, you should try to find the relevant decryptor if such exists. Security researchers are in a constant battle against cybercriminals. In some cases, they manage to create a working decryption tool that would allow victims to recover files for free.

Once you have identified which ransomware you are affected by, you should check the following links for a decryptor:

No More Ransom Project

If you can't find a decryptor that works for you, you should try the alternative methods we list below. Additionally, it is worth mentioning that it sometimes takes years for a working decryption tool to be developed, so there are always hopes for the future.

Create data backups to avoid file loss in the future

One of the many countermeasures for home users against ransomware is data backups. Even if your Windows get corrupted, you can reinstall everything from scratch and retrieve files from backups with minimal losses overall. Most importantly, you would not have to pay cybercriminals and risk your money as well.

Therefore, if you have already dealt with a ransomware attack, we strongly advise you to prepare backups for future use. There are two options available to you:

  • Backup on a physical external drive, such as a USB flash drive or external HDD.
  • Use cloud storage services.

The first method is not that convenient, however, as backups need to constantly be updated manually – although it is very reliable. Therefore, we highly advise choosing cloud storage instead – it is easy to set up and efficient to sustain. The problem with it is that storage space is limited unless you want to pay for the subscription.

Using Microsoft OneDrive

OneDrive is a built-in tool that comes with every modern Windows version. By default, you get 5 GB of storage that you can use for free. You can increase that storage space, but for a price. Here's how to setup backups for OneDrive:

  1. Click on the OneDrive icon within your system tray.
  2. Select Help & Settings > Settings.
    Go to OneDrive settings
  3. If you don't see your email under the Account tab, you should click Add an account and proceed with the on-screen instructions to set yourself up.
    Add OneDrive account
  4. Once done, move to the Backup tab and click Manage backup.
    Manage backup
  5. Select Desktop, Documents, and Pictures, or a combination of whichever folders you want to backup.
  6. Press Start backup.
    Pick which folders to sync

After this, all the files that are imported into the above-mentioned folders will be automatically backed for you. If you want to add other folders or files, you have to do that manually. For that, open File Explorer by pressing Win + E on your keyboard, and then click on the OneDrive icon. You should drag and drop folders you want to backup (or you can use Copy/Paste as well).

Using Google Drive

Google Drive is another great solution for free backups. The good news is that you get as much as 15GB for free by choosing this storage. There are also paid versions available, with significantly more storage to choose from.

You can access Google Drive via the web browser or use a desktop app you can download on the official website. If you want your files to be synced automatically, you will have to download the app, however.

  1. Download the Google Drive app installer and click on it.
    Install Google Drive app
  2. Wait a few seconds for it to be installed. Complete installation
  3. Now click the arrow within your system tray – you should see Google Drive icon there, click it once.
    Google Drive Sign in
  4. Click Get Started. Backup and sync
  5. Enter all the required information – your email/phone, and password. Enter email/phone
  6. Now pick what you want to sync and backup. You can click on Choose Folder to add additional folders to the list.
  7. Once done, pick Next. Choose what to sync
  8. Now you can select to sync items to be visible on your computer.
  9. Finally, press Start and wait till the sync is complete. Your files are now being backed up.

Report the incident to your local authorities

Ransomware is a huge business that is highly illegal, and authorities are very involved in catching malware operators. To have increased chances of identifying the culprits, the agencies need information. Therefore, by reporting the crime, you could help with stopping the cybercriminal activities and catching the threat actors. Make sure you include all the possible details, including how did you notice the attack, when it happened, etc. Additionally, providing documents such as ransom notes, examples of encrypted files, or malware executables would also be beneficial.

Law enforcement agencies typically deal with online fraud and cybercrime, although it depends on where you live. Here is the list of local authority groups that handle incidents like ransomware attacks, sorted by country:

Internet Crime Complaint Center IC3

If your country is not listed above, you should contact the local police department or communications center.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
