HakunaMatata ransomware virus removal and decryptor By Will Wisser Posted on February 6, 2017 6 min read 0 4,034 Find out which ransomware strain appends the .HakunaMatata extension to encrypted files and get useful advice on restoring the data that got locked down. A ransomware sample that’s presently in active rotation gives the phrase “hakuna matata” a completely new meaning. Instead of denoting a life with no worries, it has come to be associated with serious data accessibility problems for everybody infected. The crypto threat under consideration is called NMoreira 2.0, alias XPan or XRatTeam. The latest variant of this nasty virus affixes the .HakunaMatata extension to every single file on a contaminated computer that underwent the adverse cryptography-backed impact. For example, an original sample document named Keynote.pdf will turn into an off-limits Keynote.pdf.HakunaMatata entry. The new file extension sprinkled throughout a plagued system isn’t the only symptom of this digital onslaught. The offending application also leaves ransom notes inside folders so that victims can kick off with the paid decryption routine. These entities are called “Recovers files yako.html”. Recovers files yako.html ransom manual by HakunaMatata file virus According to the instructions provided by the threat actors, recovery is a matter of submitting a certain amount of money to their Bitcoin wallet address. The warning message starts with the following phrase, Encrypted files! All your files are encrypted. Using AES256-bit encryption and RSA-2048-bit encryption. Making it impossible to recover files without the correct private key. By the way, the punctuation and grammar of the alert is terrible, which suggests that the attackers aren’t native English speakers. Another interesting thing about the ransom note is that the crooks instruct users to install Bitmessage, a secure instant messaging solution allowing users to send encrypted messages. This way, those infected are supposed to reach the criminals and negotiate the terms of unencrypting the ransomed personal information. The HakunaMatata version of NMoreira malady propagates via a methodology that ransomware researchers are well familiar with. Its payload arrives with spam. Although some people may consider junk emails to be simply annoying, that’s a very erroneous opinion these days. By conducting well-orchestrated spam campaigns, ransomware authors achieve their nefarious objectives with high infection rates. In the case of the HakunaMatata file virus, these rogue emails are designed as if they were from some reputable organization or government agency. However, once a recipient opens an attached file to learn more, it will stealthily fire NMoreira downloader. When inside, the crypto pest scans the local, removable and network drives in order to locate the user’s important files. Then, it utilizes the above-mentioned combo of symmetric and asymmetric encryption algorithms in order to make the data inaccessible. Security analysts were able to craft an automatic free decryptor for the previous edition of this ransom Trojan, which concatenated the .__AiraCropEncrypted! or .maktub string to mutilated files and dropped “Recupere seus arquivos. Leia-me!.txt” or “How to decrypt your files.txt” ransom note. However, the current .HakunaMatata version features enhanced crypto and has not been cracked thus far. Under the circumstances, troubleshooting boils down to recovery practices that proved to work for quite a few ransomware samples. So be sure to give the steps below a shot before considering the ransom-based method.

Having scanned the specified locations, the program will display a notification about the total amount of recoverable data. Close the dialog and click the Recover button. This will hopefully help you get some of your valuable files back. HakunaMatata ransomware manual removal and file recovery Some ransomware strains terminate themselves after completing the encryption job on a computer, but some don’t. Furthermore, the HakunaMatata 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 HakunaMatata ransomware using Safe Mode with Networking Remove HakunaMatata 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. Windows XP / Vista / 7 Windows 8 / 8.1 / 10 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. 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. 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 HakunaMatata ransomware using System Restore Get rid of HakunaMatata 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. In the Command Prompt window, type cd restore and hit Enter Type rstrui.exe in the new command line and press Enter 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. 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 .HakunaMatata 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 HakunaMatata 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. 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. 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 HakunaMatata 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 TrojansDefine 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 cautionRename the vssadmin.exe process so that ransomware is unable to obliterate all Shadow Volume Copies of your files in one shotKeep 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 filesBack 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 placeUse 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. Another benefit of using the antimalware tool is that it will keep ransomware threats from intruding on your computer further on.
