MongoLock ransomware removal instructions

What is MongoLock?

MongoLock is a malicious program categorized as ransomware-type computer infection. Most programs of this type are designed to encrypt data (thus preventing victims from accessing it) and to make ransom demands. This version, however, has somewhat different behavior: it infects computers, deletes data, and formats backup drives. It also generates a ransom message within the "Warning.txt" file.

As stated in the "Warning.txt" ransom demand message, MongoLock victims' data is downloaded and backed-up on a remote server (secured by the ransomware developers). To recover their files, victims are encouraged to pay cyber criminals 0.1 Bitcoin using the provided Bitcoin wallet address. MongoLock's victims must send developers an email (via unlockandrecover@pm.me) containing their server IP addresses and proof that the money (cryptocurrency) has been transferred. According to cyber criminals, after their demands are met, they provide a data backup within 24 hours. Do not contact these cyber criminals or transfer the any cryptocurrency sum. It is very likely that they have simply deleted all data and not saved any backups/data on any remote servers. Ransomware developers commonly ignore victims once their ransom demands are met. In this case, the best, free way to retrieve lost files is to use an existing backup (if you have one) and restore everything from there .

There are many ransomware-type infections available, most of which are very similar. Typically, they encrypt data and keep it in that state until the ransom is paid (fee for the decryption tool or key is transferred). Common differences between these infections are cryptography algorithm (symmetric or asymmetric) used to encrypt data and cost of key or tool required for successful decryption. Unfortunately, most ransomware-type programs are 'uncrackable' and decryption without involvement of the developers is impossible. Only in rare cases is restoring data without their help possible - when a virus is not fully-developed or contains bugs/flaws. Therefore, maintain regular backups and store them on unplugged storage devices or remote servers. Otherwise, they might be encrypted with other data stored on the computer. Some examples of other ransomware-type programs are MongoLock: Pdff, XARCryptor, and Ahihi.

How did ransomware infect my computer?

Cyber criminals proliferate ransomware (such as MongoLock and other computer infections) through spam campaigns, trojans, unofficial, untrustworthy software download channels, or fake software updaters. Spam campaigns are used to proliferate computer infections by sending emails containing malicious attachments (Microsoft Office documents, PDF, archive or executable files, and so on). The purpose is to trick recipients into opening these attachments that, once opened, download and install viruses such as MongoLock. Trojans are programs used to cause chain infections. If installed, these malicious programs proliferate other viruses. Untrustworthy software download sources such as freeware download websites, free file hosting websites, various peer-to-peer networks (eMule, torrents) and other such tools present malicious software as legitimate. Using these websites or software, users risk download and installation of viruses rather than the expected software. Fake software updaters cause infections by downloading malware or other infections rather than the promised updates, or by exploiting bugs/flaws of outdated software.

Threat Summary:

Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.

How to protect yourself from ransomware infections?

To keep computers and operating systems safe, download, install, update software, and browse the internet with care. Do not use third party software downloaders or installers. Any software or other files should be downloaded using official and trustworthy websites (or other sources). Update all installed software using implemented functions or tools provided by official software developers only. Furthermore, avoid downloading and opening attachments presented in emails received from unknown, suspicious or other similar addresses. If the email seem irrelevant or does not concern you, ignore and delete it immediately. Having a reputable and trustworthy anti-spyware/anti-virus software installed and enabled can prevent computer infection by viruses. These tools can detect and removing various threats (computer infections) before they can do any damage to the system. If your computer is already infected with MongoLock, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware .

Step 2

Log in to the account infected with the MongoLock virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the MongoLock ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining MongoLock ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of MongoLock are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by MongoLock, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as MongoLock ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
