Dont_Worry ransomware removal instructions

What is Dont_Worry?

Discovered by MalwareHunterTeam, Dont_Worry is a ransomware-type virus that stealthily infiltrates the system and encrypts most stored files. During the process, Dont_Worry appends filenames with the ".UPS-[random_digits/letters]" extension. For instance, "sample.jpg" might be renamed to a filename such as "sample.jpg.UPS-04a72efc45a7f985". Compromised data immediately becomes unusable. After successful encryption, Dont_Worry generates a text file ("Dont_Worry.txt") and places a copy in all existing folders.

The new file contains a message informing users of the encryption and encouraging them to contact Dont_Worry's developers via an email address provided. Note that all text is in Russian. Therefore, it is safe to assume that developers are either Russian or target users who live in this country. It is currently unknown which cryptography (symmetric or asymmetric) Dont_Worry employs. In any case, a unique key (generated individually for each victim) is necessary to restore data. Developers hide all keys on a remote server. After contacting these people (not recommended), users are encouraged to pay a ransom for release of their keys. The cost is also unknown (this is not provided via email), however, these ransoms typically fluctuate between $500 and $1500 in Bitcoins or another cryptocurrency. No matter what the cost, do not pay. Ransomware developers often ignore victims, once payments are submitted. Therefore, paying does not guarantee that your files will be decrypted - this will deliver no positive result and you will simply be scammed. You are strongly advised to ignore all requests to contact these people or submit any payments. Unfortunately, there are no tools capable of decrypting data compromised by Dont_Worry free of charge. There is only one solution: to restore everything from a backup.


Dont_Worry decrypt instructions

Dont_Worry is regular ransomware and thus shares many similarities with JosepCrypt, PGPSnippet, RAPID RANSOMWARE V3, and others. Although these viruses are developed by different cyber criminals, their behavior is identical - all encrypt data and make ransom demands. There typically are just two major differences: size of ransom and type of encryption algorithm used. Unfortunately, most employ cryptographies (e.g., RSA, AES, and similar) that generate unique decryption keys. Therefore, unless the malware is not fully developed or has certain bugs/flaws, restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. These viruses present a strong case for maintaining regular data backups, however, it is very important to store them on an unplugged storage device (e.g., external hard drive, Flash drive or similar) or a remote server (such as Cloud). If not, backups are encrypted with regular data.

How did ransomware infect my computer?

To proliferate ransomware, developers employ spam emails (malicious attachments), peer-to-peer (P2P) networks, unofficial download sources, fake software updaters, and (in some cases) trojans. Malicious attachments typically come in the format of JavaScript files or MS Office documents. Once opened, these files stealthily download and install malware. P2P networks (torrents, eMule and similar) and other third party download sources (freeware download websites, free file hosting sites, etc.) present malicious executables as legitimate software. In this way, many users are tricked into downloading and installing malware. Fake updaters infiltrate malware by exploiting outdated software bugs/flaws or simply downloading and installing it rather than updates. Trojans are probably the simplest - most open "backdoors" for other viruses to infiltrate the system.

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet. Think twice before downloading/opening email attachments. If the file seems irrelevant or has been received from a suspicious/unrecognizable email address, it should not be opened and the email should be deleted immediately. Furthermore, we strongly advise you to download your applications from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus should never be used. The same applies to updating software. Keep installed applications up-to-date. To achieve this, however, use only implemented update functions or tools provided by the official developer. Have a reputable anti-virus/anti-spyware suite installed and running.
