The MindLost ransomware is a malware threat that is being distributed using various tactics to a wide range of potential victims. One of the main distribution methods is the use of email spam messages that are being made using social engineering templates. They attempt to manipulate the victims into interacting with the document with the intent of acquiring of the MindLost ransomware. Its alternative name is the .enc virus as this is the extension assigned to the processed files.

Depending on the exact configuration it may attach the virus files directly to the emails. In such cases the files pose as installers of user interest. Other tactics that are widely used for spreading malware messages include the insertion of hyperlinks. They typically pose as password reset links, login pages or notifications. The criminals are adept at stealing graphics and text components from the well-known Internet services. The criminals can opt to utilize infected documents that can be sent through the email messages. They can take the form of rich text documents, spreadsheets or presentations. As soon as they are opened a notification prompt appears which asks the victims to enable the built-in scripts. When this is done the virus infection begins.

The .enc virus can be distributed via browser hijackers which represent malware browser plugins. They are usually made compatible with the most popular applications: Mozilla Firefox, Google Chrome, Internet Explorer, Safari, Microsoft Edge and Opera. When they are installed various system changes are made which redirect the victims to hacker-controlled pages. As part of their behavior pattern the .enc virus infections can follow.

.enc Virus – More Information

The .enc virus uses a modular framework which can be further modified in future versions. Depending on the hacker configuration the behavior patterns can be modified according to the targets and the intended goals.

Such examples include Trojan code that gives the hackers the ability to spy on the users in real time. Depending on the Trojan code configuration they can also make the system record every mouse movement or keystroke in a database that is relayed in real time to the hackers.

A direct hacker connection can be initiated which allows the criminals to execute arbitrary commands. This includes the delivery of additional malware to the compromised hosts. Another possible feature is the institution of a information gathering module. It would allow the controllers to make the .enc virus harvest sensitive data which is relayed back to the operators. It is usually categorized into two main types:

  • Statistics Data — This type of data is used by the criminals to oversee the hacker campaign and plan their next attacks.
  • Private Data — Such information can directly expose the victims identity and is composed of harvested strings that are related to the users name, telephone number, address and preferences.

A persistent state of execution can be programmed which makes it difficult for the users to manually remove the active infections by themselves. The virus is modeled to manipulate the Windows registry and the operating system configuration files. As a result the victims may experience application failure, performance issues and other symptoms.

Many ransomware of late tend to delete the Shadow volume copies which make it impossible to recover any deleted data without the use of a professional data recovery solution, refer to our removal guide below for detailed instructions. The .enc virus can be programmed to distribute cryptocurrency miner software which takes advantage of the available system resources for profit.

The security analysis shows that the consequences are that the virus files are executed upon system start-up.

MindLost ransomware Encryption Process

Once all components have executed correctly the ransomware module is engaged. It uses a built-in list of target file type extensions which are processed with a strong cipher. The analysis of the acquired samples contains the following extensions:

.c, .jpg, .mp3, .mp4, .pdf, .png, .py, .txt

The ransomware engine also includes a blacklist of strings (files and folders) that are omitted from the encrypter:

  • Windows
  • Program Files
  • Program Files (x86)

A ransomware note is created as an image file which may also be imposed as the computer’s background image. The contained text reads the following:

Don’t Lose Your Mind But All Of Files Have Been Encrypted
Now it’s not too late, you can still get them back and go back to your life. All you have to do is go to xxxx:// and pay 200$ and all of yor files will be available to you again.
When paying (and you will) enter your computer”s ID. You can find your computer”s ID in a file called ID.txt in your Desktop filder. Afterwards enter your credit card information to complete the payment.
Now you can also purchase an insurance for an extra 50$. This means you will never be attacked by us again. This is strongly advised unless you want to go through all this again.
When you finish paying just go to your Desktop folder, run Decrypter.exe and all of your files will be safety decrypted and available to you again.
Q: What does it mean that all of my files have been encrypted?
A: All of your files are safe and can be restired. They are simply not accessible to you unless you have the key to decrypt them which we will only provide if you pay us. Also don”t bother trying to break the encryption it’s not possible.
For more information you can go to xxxxs:// or at xxxx://

An interesting technique employed by the hacker operators is that they have instructed a browser window to popup which shows an online payment page. The victims are sent directly to the payment gateway automatically and manipulated to pay the ransom fee.
