How to remove Dasha ransomware

Dasha ransomware may cause users to lose all their data using encryption algorithms

Dasha ransomware is a file-locking virus that belongs to the Eternity ransomware family. It uses encryption^[1] algorithms to lock users' personal files, like photos, videos, documents, databases, etc. If users do not have backups, it is almost impossible to get the files back without the cybercriminals' help.

The main goal of a ransomware attack is to extract money from victims for file decryption. When it infiltrates the system, the affected files are appended with the .ecrp extension. If a file was previously named picture.jpg, after encryption it would be named picture.jpg.ecrp. The icons are also changed to blank pages so thumbnails become unavailable.

The ransom note

Dasha ransomware generates a pop-up window which is a ransom note:

All of your files have been ENCRYPTED with DASHA RANSOMWARE
Your computer was infected with a ransomware. Your files have been encrypted and you won't
be able to decrypt them without our help.

It also changes the desktop wallpaper that displays this text:

A ransom note is a message from cybercriminals. It informs users that their files have been encrypted and that they need to contact the threat actors if they want to get them back. Of course, ransomware developers want to get paid. Usually, they choose cryptocurrencies^[2] because they provide anonymity.

We strongly advise against contacting or paying cybercriminals because they cannot be trusted. Many previous ransomware attack victims have come forward and said that they never received the promised decryption tools after paying the ransom.

Besides, it is very risky. Once you send a cryptocurrency transaction to another wallet, it is impossible to get it back or get a refund. Even though decryption without the cybercriminals' help is often impossible, there are third-party recovery tools that help in some cases so we suggest you try those.

Distribution methods

Threat actors can use various channels to spread ransomware. Most often, people get infected by installing “cracked” software^[3] from Torrent websites, and peer-to-peer file-sharing platforms.^[4] These platforms are unregulated so it is impossible to know if the packages you are downloading do not contain any malicious files.

We recommend using official web stores and developer websites. Apps that get listed on digital marketplaces, have to go through an extensive review process. Even though it may get costly, you might save in the long run by keeping your system running smoothly. Besides, there are plenty of free apps to choose from.

Cybercriminals also use social engineering methods to create convincing emails. Usually, they look like urgent and important letters from well-known companies, and they require users to open an attachment or click on a link to solve a non-existent problem.

In reality, the attachments are infected and the links may be malicious. It is best to never open any email attachments from senders you do not know. Also, keep your operating system and software updated to prevent hackers from exploiting software vulnerabilities.

Remove the intruder from your machine

If you try to recover your data first, it can result in permanent loss. It can also encrypt your files the second time. It will not stop until you remove the malicious files causing it first. You should not attempt removing the malicious program yourself. Use anti-malware tools like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes to scan your system.

This security software should find all the related files and entries and remove them automatically for you. Automatic removal is the best option because there is less risk of leaving some of the traces behind. Malware could prevent you from using antivirus software by turning it off. In that case, you should proceed with accessing Safe Mode first:

Windows 7 / Vista / XP

1. Click Start > Shutdown > Restart > OK.

2. When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.

3. Select Safe Mode with Networking from the list.

Windows 10 / Windows 8

1. Right-click on Start button and select Settings.
   
2. Scroll down to pick Update & Security.
3. On the left side of the window, pick Recovery.
4. Now scroll down to find Advanced Startup section.
5. Click Restart now.
6. Select Troubleshoot.
7. Go to Advanced options.
8. Select Startup Settings.
9. Click Restart.
10. Press 5 or click 5) Enable Safe Mode with Networking.

File recovery using third-party software

Only hackers hold the decryption key, which can unlock your files, so if you did not back them up previously, you possibly lost your files forever. You can try using data recovery software, but third-party programs cannot always decrypt the files. We suggest at least trying this method. Before proceeding, you have to copy the corrupted files and place them in a USB flash drive or another storage. And remember – only do this if you have already removed Dasha ransomware.

1. Download Data Recovery Pro.
2. Double-click the installer to launch it.
   
3. Follow on-screen instructions to install the software.
4. As soon as you press Finish, you can use the app.
5. Select Everything or pick individual folders where you want the files to be recovered from.
6. Press Next.
7. At the bottom, enable Deep scan and pick which Disks you want to be scanned.
8. Press Scan and wait till it is complete.
9. You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
10. Press Recover to retrieve your files.

The operating system is left damaged after an attack

Performance, stability, and usability issues, to the point where a full Windows reinstall is required, are expected after a malware infection. These types of infections can alter the Windows registry database, damage vital bootup, and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not able to repair it. 

This is why FortectIntego was developed. It can fix a lot of the damage caused by an infection like this. Blue Screen errors, freezes, registry errors, damaged DLLs, etc., can make your computer completely unusable. By using this maintenance tool, you could avoid Windows reinstallation.

• Press Install and wait till the program finishes the installation process
• The analysis of your machine will begin immediately
• Once complete, check the results – they will be listed in the Summary
