Typo ransomware (virus) - Decryption Steps Included
Typo virus Removal Guide
What is Typo ransomware?
Typo ransomware is a dangerous threat that may result in complete data loss
Typo ransomware is a type of malware that encrypts all personal files on a computer, rendering them inaccessible until a special decryption key is used. This advanced encryption algorithm, RSA, is utilized by cybercriminals to encrypt various files, such as photos, documents, videos, databases, and others.
Once encrypted, all personal files are appended with a .typo extension, and the regular file icons disappear. Users attempting to open these files will receive a Windows error message claiming that the file is not recognized and cannot be opened.
To restore access to their data, victims must pay a ransom of $490 or $980 in bitcoin to the cybercriminals behind the attack, as stated in the _readme.txt ransom note. The attackers also provide firstname.lastname@example.org and email@example.com emails for communication.
Typo ransomware belongs to a broader family of Djvu malware that has had over 600 variants since its release, including Coba, Goba, and Gosw. Although paying the ransom is not recommended, alternative data recovery methods can be explored to avoid contact with the attackers.
|Type||Ransomware, file-locking malware|
|File extension||Malware appends .coba extension to all affected files|
|Ransom note||_readme.txt dropped at every location where encrypted files are located|

|System fix||As soon as it is installed, malware has the potential to severely harm some system files, causing instability problems, including crashes and errors. Any such damage can be automatically repaired by using RestoroIntego PC repair|
Ransomware spreading techniques
Typo ransomware is often spread through malicious software cracks or pirated software installers. Cybercriminals use these methods to deceive users into downloading and installing their malicious software, as it often appears to be legitimate. Once the user installs the infected software, the virus begins to encrypt their personal files, demanding a ransom for their release.
To avoid infections from ransomware and other forms of malware, it is essential only to download software from reputable sources. Avoid downloading software cracks or pirated software installers, as they often contain malware that can compromise your device's security. Only download software from official websites or reputable third-party sources.
In addition to downloading software from reputable sources, keeping your operating system and software up to date is also important. Cybercriminals often exploit vulnerabilities in outdated software to spread malware, so keeping your software updated with the latest security patches can prevent these vulnerabilities from being exploited.
Finally, it is essential to use reliable antivirus software and keep it updated. Antivirus software can detect and remove malware before it can harm your device, providing an extra layer of security against ransomware and other forms of malware. Regularly update your antivirus software to ensure that it can detect and remove the latest threats. By following these guidelines, you can reduce your risk of falling victim to Typo ransomware and other types of malware.
The ransom note
When a victim is targeted by a ransomware attack, they may receive a message known as a ransom note. This note provides the victim with instructions on how to pay a ransom to the attackers in exchange for the decryption of their encrypted data. Along with the payment instructions, the ransom note typically includes a deadline for payment and may also contain threats of further harm if the payment is not made.
While some ransomware attacks use this tactic, others, such as Djvu, take a more professional approach. The ransom note is usually displayed on the victim's computer or device in the form of a text file, image, or webpage. As soon as the file encryption is completed by the Typo virus, the victim will receive the following message.
Don't worry, you can return all your files!

As with many viruses of its kind, the virus may offer to send a file for test decryption to demonstrate its capability. However, placing trust in cybercriminals carries inherent risks, such as the potential loss of both payment and encrypted data. Consequently, it is advisable to pursue an alternate course of action, such as removing the malware from the system and utilizing alternative methods for data recovery.
Deal with ransomware infection and attempt file recovery
It is crucial to approach a ransomware attack with caution and take the appropriate steps to avoid making costly mistakes. Reacting impulsively, such as paying the ransom to cybercriminals, may result in the loss of hundreds of dollars with no guarantee of receiving the decryption key.
The first step after discovering a ransomware attack is to disconnect the affected computer from the internet. This will prevent the malware from spreading or communicating with its Command and Control servers, which cybercriminals use to send instructions to the ransomware.
Next, run a comprehensive anti-malware scan with the latest version of your antivirus software, ensuring that virus definitions are up-to-date. This scan will detect and remove the Typo ransomware, allowing you to proceed with data recovery.
If you have a recent backup of your data, restoring your computer from the backup may be the quickest and most effective way to recover your files. However, if no backups are available, alternative options exist, such as using decryption tools like Emsisoft's decryptor or specialized data recovery software. We provide detailed instructions on how to use it (along with other alternative recovery methods) below.
After removing the ransomware, use a system repair utility, such as RestoroIntego, to scan your system and ensure any malware-related system errors or crashes are resolved. While reinstalling the Windows operating system can achieve the same result, it may be too complex for some users and result in losing all files.
It is also essential to prevent future attacks, such as creating reliable backups of important files and staying vigilant against potential threats. Reporting the incident to law enforcement and regaining access to any compromised accounts, such as online banking or social media, should also be a priority.
In conclusion, taking the appropriate measures after a ransomware attack is crucial to minimize the damage and prevent future incidents. By following the below steps and taking additional precautions, victims can successfully recover their data and protect themselves against future cyber threats.
Getting rid of Typo virus. Follow these steps
Important steps to take before you begin malware removal
File encryption and ransomware infection are two independent processes (although the latter would not be possible without the former). However, it is important to understand that malware performs various changes within a Windows operating system, fundamentally changing the way it works.
IMPORTANT for those without backups! →
If you attempt to use security or recovery software immediately, you might permanently damage your files, and even a working decryptor then would not be able to save them.
Before you proceed with the removal instructions below, you should copy the encrypted files onto a separate medium, such as USB flash drive or SSD, and then disconnect them from your computer. Encrypted data does not hold any malicious code, so it is safe to transfer to other devices.
The instructions below might initially seem overwhelming and complicated, but they are not difficult to understand as long as you follow each step in the appropriate order. This comprehensive free guide will help you to handle the malware removal and data recovery process correctly.
If you have any questions, comments, or are having troubles with following the instructions, please do not hesitate to contact us via the Ask Us section.
It is vital to eliminate malware infection from the computer fully before starting the data recovery process, otherwise ransomware might re-encrypt retrieved files from backups repeatedly.
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
- 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.
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.
Scan your system with anti-malware
If you are a victim of ransomware, you should employ anti-malware software for its removal. Some ransomware can self-destruct after the file encryption process is finished. Even in such cases, malware might leave various data-stealing modules or could operate in conjunction with other malicious programs on your device.
SpyHunter 5Combo Cleaner or Malwarebytes can detect and eliminate all ransomware-related files, additional modules, along with other viruses that could be hiding on your system. The security software is really easy to use and does not require any prior IT knowledge to succeed in the malware removal process.
Restore Windows "hosts" file to its original state
Some ransomware might modify Windows hosts file in order to prevent users from accessing certain websites online. For example, Djvu ransomware variants add dozens of entries containing URLs of security-related websites, such as 2-spyware.com. Each of the entries means that users will not be able to access the listed web addresses and will receive an error instead.
Here's an example of “hosts” file entries that were injected by ransomware:
In order to restore your ability to access all websites without restrictions, you should either delete the file (Windows will automatically recreate it) or remove all the malware-created entries. If you have never touched the “hosts” file before, you should simply delete it by marking it and pressing Shift + Del on your keyboard. For that, navigate to the following location:
Use Emsisoft decrytor for Djvu/STOP
If your computer got infected with one of the Djvu variants, you should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone – it only works if data was locked with an offline ID due to malware failing to communicate with its remote servers.
Even if your case meets this condition, somebody from the victims has to pay criminals, retrieve an offline key, and then share it with security researchers at Emsisoft. As a result, you might not be able to restore the encrypted files immediately. Thus, if the decryptor says your data was locked with an offline ID but cannot be recovered currently, you should try later. You also need to upload a set of files – one encrypted and a healthy one to the company's servers before you proceed.
- 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:
- “Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
- “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.
- “This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.
Restore files using data recovery software
Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.
While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.
Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important 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
- 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 where 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.
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
- Free Ransomware Decryptors by Kaspersky
- Free Ransomware Decryption Tools from Emsisoft
- Avast decryptors
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:
- Click on the OneDrive icon within your system tray.
- Select Help & Settings > Settings.
- 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.
- Once done, move to the Backup tab and click Manage backup.
- Select Desktop, Documents, and Pictures, or a combination of whichever folders you want to backup.
- Press Start backup.
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.
- Download the Google Drive app installer and click on it.
- Wait a few seconds for it to be installed.
- Now click the arrow within your system tray – you should see Google Drive icon there, click it once.
- Click Get Started.
- Enter all the required information – your email/phone, and password.
- Now pick what you want to sync and backup. You can click on Choose Folder to add additional folders to the list.
- Once done, pick Next.
- Now you can select to sync items to be visible on your computer.
- Finally, press Start and wait till the sync is complete. Your files are now being backed up.
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Typo and other ransomwares, use a reputable anti-spyware, such as RestoroIntego, SpyHunter 5Combo Cleaner or Malwarebytes
How to prevent from getting ransomware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
