The Mystic ransomware infection can be noticed at its end when it drops a ransom note ransom.txt on the Desktop. The message is left by hackers who demand payment of 1.01 Bitcoin in exchange for decryptor and the unique decryption key that is believed to restore data.

This article is created to inform infected users about the damage caused by Mystic ransomware and help them with the removal process. The guide at the end of the article suggests alternative data recovery methods.

Mystic Ransomware – Delivery Techniques

Different methods can be used for Mystic payload distribution. Generally, hackers choose some of the following approaches:

  • Spam email messages – the malicious file is usually hidden in an attachment or injected into a webpage that is presented as a link. Links land on the corrupted web page that is set to download and install the ransomware automatically.
  • Fake notifications of software updates – be careful and inspect pop-ups thoroughly when they prompt the installation of new software versions
  • Hacked or hacker-controlled download sites like BitTorrent
  • Installation set ups of different types of free software that mimic legitimate applications

Mystic Ransomware – Detailed Analysis

Mystic ransomware may implement techniques that stop currently active PC protection and penetrates the system unnoticeably. The threat is triggered by a single executable file that navigates all system modifications during the attack. For the complete infection Mystic ransomware may need additional files that are likely to be created or dropped in the following Windows folders:

  • %AppData%
  • %Temp%
  • %Roaming%
  • %UserProfile%

Have in mind that sometimes malicious files are obfuscated and appear as legitimate system files, so if you choose tо remove the threat manually you need to have some computer knowledge to find all ransomware associated files. Otherwise, some leftovers can remain on the system, and it will continue to be infected with Mystic.

Additional damages that Mystic can cause are Windows Registry modifications, and Shadow Volume copies wipe. In the common case ransomware enters the Window Registry editor to employ some changes of the Run and RunOnce keys. These keys manage all processes that start automatically at each Windows start. Once Mystic crypto virus adds its specific values in the keys mentioned above, its persistence increases. The same keys may be used for the automatic display of the ransom note – ransom.txt that reads the following:

Your computer has been hacked and your files have been locked.
You have 5 days left to recover your files so quickly follow recovery process below.
Recovery Process in 3 easy steps (Automated System. No human intervention. Works 24/365):

2) Send payment of 1.01 Bitcoin to the address in the website given above.
3) In approx 15 minutes after making the payment to the bitcoin address, Go back to the above website. If payment is successful then you will receive unlock instructions.
Don’t delete or modify this ransom file till recovery of files as no recovery is possible without this file. This file is on your desktop for future use.
List of files which have been locked are given below.

Shadow volume copies are copies of the original files stored on the PC that serve as a backup option. Mystic can delete them to prevent the recovery of encrypted files. This can be done with a single command entered in the Command Prompt:

→ vssadmin.exe delete shadows /all /quiet

Mystic ransomware authors may have designed it to establish a connection with a server controlled by them once the malicious payload is started on the PC. Such a consequence can grant them private access to the infected machine which makes it extremely vulnerable to other malware attacks. Furthermore, your privacy is also at risk because of possible credentials thefts.

Mystic Ransomware – Data Encryption

Mystic has a built in encryption module that modifies the original code of each file that is mentioned in its target data list. During the encryption, users may witness system slowdowns as well as processes that use an increased amount of memory. For the encryption, Mystic ransomware is believed to use strong cipher algorithm like AES or RSA in order to make decryption process more difficult. Like the majority of data locker ransomware, Mystic is likely to target frequently used file formats that store valuable information. Thus once it penetrates the system, its encryption module can affect documents, videos, photos, images, music, projects, databases, archives, etc. Mystic ransomware doesn’t mark corrupted data with particular extension instead it generates a list of all encrypted files in its ransom note. Encrypted files remain unusable until the unique decryption key is applied to the decryptor. Unfortunately, the key is possessed by crooks who demand a ransom payment of 1.01 BTC for it. At the moment of creating this article, this amount equals to 3855.07 US Dollars not $280 as mentioned in the ransom note. This is an insane sum of money, so we recommend you to look for alternative data recovery solutions first and avoid investments in further cyber criminals’ misuses.

Remove Mystic Ransoware and Restore Data

Mystic ransomware should be eliminated as soon as possible from the infected system. Otherwise, it will corrupt all new files. Even worse is the chance to spread itself to all devices that are connected to the same network as the infected machine. The detailed guide below provides Mystic ransomware removal instructions. After the removal backup all encrypted files and check step “Restore files encrypted by Mystic” for alternative data recovery solutions.
