Goba ransomware (virus) - Free Guide

What is Goba ransomware?

Goba is a dangerous computer virus that is after your documents and other files

Goba is a ransomware-type virus that is designed to target computers and devices with the aim of extorting money from its victims. This particular version belongs to the Djvu family and was introduced by cybercriminals in early March of 2023.

Goba virus is typically spread through illegally downloaded software installers from untrusted websites. Malicious hackers may also use other means of transmission. Irrespective of the method used to distribute the virus, all victims unwittingly download it and only realize that something is wrong when they observe the initial signs of infection.

Once the ransomware infiltrates a system, it encrypts^[1] all the data stored on that network or device. The encryption makes the data inaccessible to legitimate users until they pay a ransom for a decryption key.

After the encryption, Goba ransomware displays a ransom note named _readme.txt on the infected device or system. The note informs victims of the data encryption and demands a payment of $980 (with a $490 discount) in bitcoin in exchange for decryption. Communication with the hackers can be initiated via two emails provided in the note- datarestorehelp@airmail.cc and support@freshmail.top.

Even though there are news about more secured emails and end-to-end encryption in Gmail and other platforms, there are many ways that hackers and criminals are known to use. These methods allow threats to get spread via email attachments and links in emails with malicious code or direct ransomware payload. Threat actors can use cracked software and other malware for distribution of this Goba ransomware too, so be cautious. Stay safe online.

Ransom note – what to expect

Djvu ransomware variants like Qoqa, Iowd, or Vvoo are specifically designed to extort money from their victims by encrypting all kinds of popular file formats, including .jpg, .doc, .pdf, and more. These viruses are programmed to avoid system files like executables to ensure that the device's operating system is not damaged, although unintended consequences may still arise.

After the encryption process, the malware leaves a ransom note on the compromised system to inform the user of the ransom payment and possible file recovery. Here is a sample of what the victims may read in the ransom note:

Cybercriminals employ various tactics to coerce victims into paying the ransom. One of the most common tactics is to convince them that paying the ransom is the only way to recover their encrypted files. To make their offer seem more appealing, attackers often include a 50% discount if the payment is made within a specific timeframe, usually within three days. They may also offer a free decryption service to prove their capability of decrypting the files.

These tactics are designed to create a sense of urgency and desperation among victims, making them believe that paying the ransom quickly is their best option. In reality, however, paying the ransom does not guarantee that the attacker will provide the decryption key or that the key will work as expected. Moreover, it only encourages cybercriminals to continue their illicit activities, fueling the growth of ransomware attacks.

Goba virus removal: how to make your system functional again

As soon as malware gains access to a system, it can establish a connection to a remote Command & Control^[2] server. This connection allows attackers to direct the malware to perform various tasks, such as updating itself or distributing new payloads. Consequently, it's essential to disconnect your computer from the internet and network before beginning the process of removing the ransomware.

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

After disconnecting your computer from the internet, you can remove Goba ransomware. It is recommended to use advanced security software like SpyHunter 5Combo Cleaner or Malwarebytes to ensure effective removal. In case the malware is trying to prevent the elimination process, access Safe Mode and perform a comprehensive system scan from there. However, before doing this, ensure your security software is up-to-date to detect the latest threats.

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.

We also advise scanning the system with FortectIntego PC repair utility, as some system files might get corrupted due to malware infection. This way, you can get rid of troubles such as BSODs,^[3] crashes, errors, and other stability issues without reinstalling the operating system.

Attempt to recover data

Now that the Mzop ransomware has locked your files, it's time to explore your options for unlocking them without resorting to paying the ransom. Most people are not familiar with the intricacies of data encryption and may feel helpless when it comes to restoring encrypted files. However, there are several methods that you can try to recover your data.

Here are some options to consider:

1. Restore your files from a recent backup. This is the most straightforward and reliable method of data recovery, provided that you have a backup of your files that is recent enough.
2. Use data recovery software to scan your hard drive and attempt to recover your encrypted files. There are various software tools available that can help you recover deleted or damaged files, which may include some of your encrypted files as well.
3. Try using a decryption tool from Emsisoft, specially designed to help victims of Djvu ransomware. While there's no guarantee that this tool will work for everyone, it's worth a try before considering paying the ransom.

We recommend trying the Goba decryption tool as your first option, as it may help you restore your files without paying the ransom.

• Download the app from the official Emsisoft website.
• After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.
  
• If User Account Control (UAC) message shows up, press Yes.
• Agree to License Terms by pressing Yes.
  
  
• After Disclaimer shows up, press OK.
• The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.
  
• Press Decrypt.
  
  

From here, there are three available outcomes:

1. “Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
2. “Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
3. “This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.

If this method is unsuccessful, you could always use specialized data recovery software.

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

Security researchers are continuously working to develop decryption tools for various ransomware strains, which can help you recover your files without having to pay the ransom. In some instances, law enforcement agencies have seized servers from the perpetrators, leading to the release of decryption keys.
