LOCKEDS ransomware removal instructions

What is LOCKEDS?

LOCKEDS is a piece of malicious software, classified as ransomware. It belongs to the DCRTR-WDM malware family. LOCKEDS encrypts victim's data and keeps locked, until a ransom is paid. During the encryption process, all affected files are retitled with ".LOCKEDS" extension; e.g. making a file named something like "1.jpg" appear as "1.jpg.LOCKEDS". After this process is complete, files "HOW TO DECRYPT FILES.hta" and "HOW TO DECRYPT FILES.txt" are dropped into every compromised folder.

Both the HTML application and the text file contain ransom messages. The text file informs victims that all of their data has been encrypted with a unique key. To retrieve it, they must contact the developers of LOCKEDS via the email address listed. The user's personal ID number (written in both notes) must be copied into the email's subject/title. The text file ends with warnings against delaying contact, as that may prevent the possibility of decryption. The message in the HTML application is more detailed. In it, users find that the size of the ransom will depend on how quickly they establish contact. The payment will have to made in Bitcoin cryptocurrency (instructions on how to procure Bitcoins are also given). To prove their ability to decrypt the data, the criminals offer to decrypt one file free of charge. The test file is to be no larger than 1Mb (non-archived) and contain no valuable information, such as database, backup, large excel sheet, etc. Changing filenames and attempting to decrypt the affected files with third party software - are told to result in permanent data loss. Unfortunately, it is true that usually only the software used for the initial encryption - can decrypt the data it encrypted. However, it is expressly recommended against meeting the ransom demands. Cyber criminals are not to be trusted. There are no guarantees that these individuals will hold up the end of the deal. Often they do not and victims do not receive the promised decryption tools/keys. In such cases, users data remains encrypted and essentially - worthless. Further encryptions can be prevented by removing the ransomware, but removal will not restore already compromised data. It may be recovered form a backup, if one was prior to the infection and stored separately.

Hakbit2HamlampampomABAT are a few examples of other ransomware. Malicious software of this kind all encrypts files and requests payment for decryption. There are some crucial differences, such as the cryptographic algorithm they use (symmetric or asymmetric) and the ransom size. The latter vary between three-digit and four-digit sums. Digital currencies are preferred by cyber criminals (with cryptocurrencies - the most popular), as transactions of them are difficult/impossible to trace. Unless a ransomware has flaws/bugs or is still in development, manual decryption (without the involvement of the cyber criminals behind the infection) - is impossible. To protect data against encrypting/damaging attacks - backups should be kept in remote servers and/or unplugged storage devices. It is best to store multiple backups in different locations.

How did ransomware infect my computer?

Ransomware and other malware is typically proliferated via trojans, spam campaigns, unreliable download sources, fake software updaters and "cracking" (activation) tools. Trojans are malicious programs, designed to cause chain infections (download/install other malware). Massive scale spam campaigns are used to send out emails, containing infectious attachments (or web-links leading to them). These emails are usually deceptively marked as "official", "important", "urgent" and similar. The attachments can be in various formats (e.g. archive and executable files, PDF and Microsoft Office documents, JavaScript, etc.). When the attached files are executed, run or otherwise opened - they are triggered to infect the system. Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting sites, as well as other third party downloaders - are considered to be unreliable and untrustworthy. Hence, more likely to offer malicious content. Fake updaters infect systems by exploiting the weaknesses of outdated software. However, they can also simply install malware instead of the promised updates. Illegal activation "cracking" tools can download/install malware, rather than activate licensed product.

To eliminate LOCKEDS virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

Suspicious and irrelevant emails should not be opened. Any attachments (or links) found in suspect mail must never be opened - as that is the origin of a potential infection. It is advised to only use official and verified download channels. Software activation and updating should be done with tools/functions provided by legitimate developers, as illegal activation tools ("cracks") and third party updaters are deemed to be high-risk. It is strongly recommended to have a reputable anti-virus/anti-spyware suite installed and kept up-to-date. Said programs are to be used for regular system scans and removal of detected threats/issues. If your computer is already infected with LOCKEDS, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Free decryption as guarantee
Before paying you can send us up to 1 file for free decryption. The total size of files must be less than 1Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)
How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click 'Buy bitcoins', and select the seller by payment method and price.
Also you can find other places to buy Bitcoins and beginners guide here:
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.

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 LOCKEDS 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 LOCKEDS 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 LOCKEDS 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 LOCKEDS, 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 LOCKEDS 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, and 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:
