What is the Tabufa ransomware?

The whole hype around file-encrypting ransomware seems to have calmed a while ago, but it doesn’t mean that the menace is over at all. In fact, these attacks have become technically refined and some of them have shifted towards a targeted approach. The new strain called Tabufa ransomware demonstrates how real the threat is and also shows that cyber extortionists are still in play. Moreover, this sample is a remake of an old lineage referred to as GlobeImposter 2.0, which has been mostly idle for more than a year and has now resurfaced in the big outbreak. As the name of the spinoff suggests, it uses the .tabufa extension to blemish every file encrypted in the course of the e-raid. So, for instance, a picture Nature.jpg will assume a shape of an inaccessible object named Nature.jpg.tabufa. Obviously, the original filenames aren’t scrambled and it’s easy to work out what exactly has been encoded on a compromised machine.

An inalienable attribute of the Tabufa ransomware incursion is what’s called the ransom note. That’s a document with decrypt instructions performing the function of a link between the victim and the malicious actors on the other end. In this particular scenario, it’s an entity named how_to_back_files.html that opens up in the user’s default web browser. By the way, the resulting title of the HTML page is “How to open your files” instead. According to this rescue message, the only way to regain access to the skewed data is to purchase the decryptor owned by the malefactors. To get started on the process, the plagued user is supposed to contact the black hats at tabufa@protonmail.com or, if there is no response within one day, use another email address, namely tabufa@airmail.cc. As proof that the deal is real, the felons offer the infected person to attack one file up to 5MB to the message. Another important requirement is to paste the unique ID in the email body so that the villains can purportedly identify the victim and provide the right private decryption key upon payment. Here are the full contents of the how_to_back_files.html document.

Decryptors of other users are unique and will not fit your files and use of those will result in a loose of data.

In response to the desperate user’s email, the attackers will indicate the size of the ransom and the Bitcoin address to submit it to. The amount depends on who the victim is: for a regular home user, the buyout sum shouldn’t exceed 0.1 BTC, which is worth about $500; for an enterprise computer network or server, the demands can be multiple times higher. Unfortunately, it’s only when the attack chain reaches the payment threshold that most people regret having neglected their computing hygiene, which actually allowed the onslaught to take place.

The common entry point for the Tabufa ransomware is malicious spam or phishing. The idea is prosaic – to fool the recipient into opening a contagious email attachment or following an embedded link. In most cases, the toxic file is a Word document that prompts the user to turn on macros and thus allegedly unlock the content. However, doing so is a bad idea because a malicious PowerShell script will be launched in the background and download the Tabufa virus from the remote server. A couple of ostensibly innocuous clicks suffice to get hit. If the quandary has already take place and all valuable files have been encrypted, the first thing to do is try all available recovery options that have nothing to do with the ransom. Keep reading to learn the walkthrough that will help get rid of the Tabufa ransomware and hopefully reinstate the hostage information.

2. Rest assured the scan report will list all items that may harm your operating system. Select the detected entries and click Fix Threats to get the troubleshooting completed.

Data recovery toolkit to the rescue

Some strains of ransomware are known to delete the original files after the encryption routine has been completed. As hostile as this activity appears, it can play into your hands. There are applications designed to revive the information that was obliterated because of malfunctioning hardware or due to accidental removal. The tool called Data Recovery Pro by ParetoLogic features this type of capability therefore it can be applied in ransom attack scenarios to at least get the most important files back. So download and install the program, run a scan and let it do its job.

Some ransomware strains terminate themselves after completing the encryption job on a computer, but some don’t. Furthermore, the Tabufa blackmail virus may prevent victims from using popular antimalware tools in order to stay on board for as long as possible. Under the circumstances, it may be necessary to utilize the Safe Mode with Networking or System Restore functionality.

Remove Tabufa ransomware using Safe Mode with Networking

Remove Tabufa ransomware using Safe Mode with Networking

Boot into Safe Mode with Networking. The method to do it depends on the version of the infected operating system. Follow the instructions below for your OS build.

  • Restart the machine. When the system begins loading back up, keep pressing the F8 key with short intervals. The Windows Advanced Options Menu (Advanced Boot Options) screen will appear.Boot into Safe Mode with Networking on Windows Vista and 7
  • Use arrow keys to select Safe Mode with Networking and hit Enter. Log on with the user account infected by the ransomware.
  • Click on the Search icon next to the Start menu button. Type msconfig in the search field and select the System Configuration option in the results. Go to the Boot tab in the upper part of the GUI.Boot options on Windows 8, 8.1 and 10
  • Under Boot options, select Safe boot and click the Apply button. A prompt will appear to reboot the computer so that the changes take effect. Select the Restart option and wait for the system to load into Safe Mode. Again, log on with the ransomware-stricken user account.

In Safe Mode, the ransom Trojan won’t keep security software from running or otherwise thwart troubleshooting. Open your preferred web browser, download and install an antimalware tool of choice and start a full system scan. Have all the detected ransomware components removed in a hassle-free way.

Get rid of Tabufa ransomware using System Restore

Get rid of Tabufa ransomware using System Restore

System Restore enables Windows users to roll back all changes made to the OS since the latest restore point creation time. This feature can help eliminate the most persistent ransomware. Before going this route, though, make sure System Restore had been enabled prior to the breach, otherwise the method will be inefficient.

  • Open Windows Advanced Options Menu as described in the previous section: hit F8 repeatedly when the PC is starting up. Use arrow keys to highlight the Safe Mode with Command Prompt entry. Hit Enter.Safe Mode with Command Prompt
  • In the Command Prompt window, type cd restore and hit Entercd restore command
  • Type rstrui.exe in the new command line and press EnterType rstrui.exe command
  • When the System Restore screen pops up, click Next, select a restore point that predates the contamination, and use the application’s controls to roll back the system to this earlier state.System Restore window

Be advised that even after the ransomware is removed, files will still be encrypted and inaccessible. The malicious code cleanup part, however, is important because it keeps a relapse of the infection from occurring further on and eliminates all opportunistic malware.

Ways of non-ransom recovery of .tabufa files

Cracking the crypto used by this ransom Trojan is more of a science fiction thing rather than an attainable prospect for the masses. This is why the troubleshooting in predicaments of this sort is a matter of two approaches: one is to pay the ransom, which isn’t an option for many victims; and the other is to apply instruments that take advantage of the ransomware’s possible weaknesses. If the latter is your pick, the advice below is a must-try.

Backups can make your day

Backups can make your day

Not only are you a lucky person in case you’ve been backing up your most important files, but you’re also a wise and prudent user. This isn’t necessarily a resource-heavy activity these days – in fact, some providers of online services are allocating a sufficient size of cloud storage space for free so that every customer can easily upload their critical data without paying a penny. Having removed the Tabufa ransomware, therefore, all you have to do is download your stuff from the remote server or transfer it all from an external piece of hardware if that’s the case.

Restore previous versions of encrypted files

Restore previous versions of encrypted files

A positive upshot of using this technique depends on whether or not the ransomware has erased the Volume Shadow Copies of the files on your PC. This is a Windows feature that automatically makes and keeps the backups of data elements on the hard drive as long as System Restore is enabled. The cryptoware in question is programmed to switch off the Volume Shadow Copy Service (VSS), but it has reportedly failed to in some cases.

Checking one’s options regarding this workaround is doable in two ways: through the Properties menu of each file or by means of the remarkable open-source tool called Shadow Explorer. We recommend the software-based way because it’s automated, hence faster and easier. Just install the app and use its intuitive controls to get previous versions of the encrypted objects reinstated.
Shadow Explorer

Alternatively, you can leverage the Previous Versions feature, which is native to Windows operating system. This method is more cumbersome that the use of ShadowExplorer, but it can help restore the most important individual files on condition that the ransomware failed to disable the Volume Snapshot Service on the computer. Right-click on a file of choice and select Properties. Then, go to the Previous Versions tab as illustrated below.
Previous Versions

Go ahead and pick the file’s latest backup version on the list. Use the Copy or Restore buttons to reinstate this object to a new path or to its original folder, respectively.

Ransomware Prevention Tips

To avoid the Tabufa ransomware and other file-encrypting infections in the future, follow several simple recommendations:

  • Toggle your email provider’s anti-spam settings to filter out all the potentially harmful incoming messages. Raising the bar beyond the default protection is an important countermeasure for ransom Trojans

  • Define specific file extension restrictions in your email system. Make sure that attachments with the following extensions are blacklisted: .js, .vbs, .docm, .hta, .exe, .cmd, .scr, and .bat. Also, treat ZIP archives in received messages with extreme caution

  • Rename the vssadmin.exe process so that ransomware is unable to obliterate all Shadow Volume Copies of your files in one shot

  • Keep your Firewall active at all times. It can prevent crypto ransomware from communicating with its C&C server. This way, the threat won’t be able to obtain cryptographic keys and lock your files

  • Back up your files regularly, at least the most important ones. This recommendation is self-explanatory. A ransomware attack isn’t an issue as long as you keep unaffected copies of your data in a safe place

  • Use an effective antimalware suite. There are security tools that identify ransomware-specific behavior and block the infection before it can do any harm.
These techniques are certainly not a cure-all, but they will add an extra layer of ransomware protection to your security setup.

Revise your security status

Post-factum assessment of the accuracy component in malware removal scenarios is a great habit that prevents the comeback of harmful code or replication of its unattended fractions. Make sure you are good to go by running an additional safety checkup.
