Dcrtr-Crypt ransomware removal instructions

What is Dcrtr-Crypt?

Dcrtr-Crypt is categorized as ransomware-type program, a new version of Dcrtr ransomware. It encrypts all data stored on a computer and displays a ransom-demand messages in a pop-up window and the "HOW TO DECRYPT FILES.txt" text file. The pop-up window is opened through the "info.hta" file. The .hta and "HOW TO DECRYPT FILES.txt" files can be found in every folder containing encrypted data. Dcrtr-Crypt renames encrypted files by adding the ".crypt" extension. For example, "1.jpg" becomes "1.jpg.crypt".

The pop-up window (displayed through the "info.hta" file) states that a computer has been infected with Dcrtr-Crypt ransomware and has encrypted all files. To restore them, users are required to contact ransomware developers via the btcbrewery@protonmail.com or btcbrewery@india.com email address. According to the message, the ransom size depends on how quickly these criminals are contacted. It is also states that the amount must be paid in Bitcoins. When these cyber criminals are contacted and their ransom demands are met, they promise to send a decryption tool capable of decrypting all the locked files. They also encourage victims not to rename the files or to try to decrypt them using other tools, since this might lead to permanent data loss or increased cost of decryption. Whatever claims they make, we advise you not to contact Dcrtr-Crypt's developers. Cyber criminals often ignore victims once they receive the requested cryptocurrency payment. In this way, people are scammed. Unfortunately, there are no tools capable of decrypting Dcrtr-Crypt encryption free of charge. Generally, ransomware developers use cryptographies (symmetric or asymmetric) that generate unique keys and are 'uncrackable'. Therefore, it is impossible to decrypt data without using a specific tool or key. Cyber criminals store these keys on remote servers controlled only by them. The best (free) way to retrieve locked files is to use a backup created earlier and restore everything from there.

Dcrtr-Crypt developers use the same text within "HOW TO DECRYPT FILES.txt" as the Sorry, RPD, PAIN LOCKER, Nano, and Garrantydecrypt ransomware. Furthermore, information displayed in the pop-up window and its interface are taken from Dharmransomware. Most programs of this type are very similar. They encrypt data and keep it in that state unless a ransom is paid. They can differ in terms of cryptography used to encrypt data and ransom size (cost of decryption tool). Typically, ransomware-type infections cannot be 'cracked' without the involvement of the developers, unless the software is not fully developed or contains bugs/flaws. In any case, we recommend that you create regular data backups and store them on remote servers or unplugged storage devices (otherwise backups are encrypted with other regular data).

How did ransomware infect my computer?

To proliferate ransomware-type computer infections, cyber criminals use Windows and various other software 'cracks', trojans, spam email campaigns, fake software updaters and untrustworthy software download sources/channels. Using software cracks generally risks computer infections, rather than being able to use licensed (paid) software free of charge. Many cyber criminals take advantage of users' interest in unpaid software. Trojans are malicious programs that cause chain infections - they proliferate other malicious programs. If a trojan is present on a system, it is very likely that it is also proliferating other infections. Cyber criminals who use spam campaigns send emails that contain malicious attachments. If opened, these download and install malicious software. Examples of attached files are Microsoft Office documents, PDF files, executable files, archive files such as ZIP, RAR, and so on. Fake software updaters infect computers by exploiting outdated software bugs/flaws or by downloading and installing malware rather than the expected updates. Various free file hosting, freeware download, and other websites, peer-to-peer (P2P) networks such as torrent clients, eMule and other dubious sources, present malicious executables as legitimate software. Using them, cyber criminals often trick users into downloading and installing computer infections.

How to protect yourself from ransomware infections?

Be careful while browsing the web, installing/downloading, or updating software. Do not open email attachments or website links presented in emails without making sure that they can be trusted. Files that seem irrelevant and those received from suspicious, unknown email addresses should never be opened. All software should be downloaded from official, trustworthy sources and using direct download links only. Various third party downloaders and installers often include rogue applications. Therefore, we do not recommend that you use them. Keep installed applications up-to-date, however, use implemented features or tools provided by the official developers. Having a reputable anti-virus/anti-spyware suite installed and running is helpful in preventing computer infiltration by ransomware and many other threats. These programs detect and terminate malware before it does any harm. If your computer is already infected with Dcrtr-Crypt, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail BTCBREWERY@protonmail.com or btcbrewery@india.com
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.
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.

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 Dcrtr-Crypt 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 Dcrtr-Crypt 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 Dcrtr-Crypt 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 Dcrtr-Crypt, 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 Dcrtr-Crypt 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.
