MindLost ransomware removal instructions

What is MindLost?

Discovered by MalwareHunterTeam, MindLost is a ransomware-type virus that infiltrates the system and encrypts a portion of stored data. Note that Microsoft detects this malware under another name - Paggalangrypt. During encryption, MindLost appends filenames with the ".enc" extension (e.g., "sample.jpg" is renamed to "sample.jpg.enc"). From this point, using compromised files becomes impossible. Immediately after encryption, MindLost downloads an image file from the Internet and sets it as the desktop background.

Note that MindLost targets only a small number of data types (full list below). In addition, it is supposed to skip the "Windows", "Program Files" and "Program Files (x86)" folders. Bear in mind, however, that MindLost is still in development and, thus, has certain flaws. For example, rather than encrypting files stored on all plugged storage devices, MindLost just targets those stored in the "C:\\Users" folder. Furthermore, MindLost's binary file contains information that is not supposed to be there. For example, it contains a greeting message ("Hi Daniel Ohayon!") that is typically included by the SDK (Software Development Kit), once the file is created. Although it is highly unlikely, this might be intentional - a method to trick "cyber police" into pursuing the wrong people. In addition, the binary file contains a hard-coded link to MindLost's database. Therefore, malware security researchers are able to connect and retrieve information (e.g., encryption/decryption keys) necessary to restore compromised data. These are just a few major flaws with MindLost ransomware. This malware is not yet actively distributed, since it is obviously in a development state, however, there is a high probability that this situation will change - flaws will be removed and developers will start proliferating this malware intensively.

MindLost ransomware's desktop wallpaper contains a message informing victims about the encryption and instructing them what to do next. In order to restore files, victims must visit a given URL and pay a ransom. Although it is currently unknown whether MindLost uses symmetric or asymmetric cryptography, in both cases decryption requires a key generated uniquely for each victim. This allows ransomware developers to generate revenue - they hide keys on a remote server and encourage victims to submit payments for their release. Unlike other ransomware-type viruses, however, MindLost does not demand a cryptocurrency payment - users must enter their credit card information and submit a payment of $200. The idea of this is to gather various banking information. The data can be misused for further online purchases and so on. Developers will probably also sell this information to third parties (cyber criminals). Therefore, entering such information and paying any ransom can lead to serious privacy issues. In addition, criminals often ignore victims, once payments are submitted. Therefore, paying typically gives no positive result and users are scammed. Therefore, we strongly advise you to ignore all requests to submit payments. Unfortunately, there are currently no tools capable of restoring data encrypted by MindLost and you can only restore everything from a backup. Note that, as mentioned above, the link to MindLost's database is hard-coded, and so there is a high probability that malware security researchers will deliver a solution.

There are dozens of ransomware-type viruses that share similarities with MindLost. The list of examples includes (but is not limited to) GANDCRAB, InsaneCrypt, Rapid, and Skeleton. Although these viruses are developed by different cyber criminals, all have identical behavior - they encrypt data and make ransom demands. In most cases, the only major differences are size of ransom and type of encryption algorithm used. Research shows that, unfortunately, most of these viruses employ algorithms that generate unique decryption keys. Therefore, unless the malware is still in development or has certain bugs/flaws (keys are hard-coded, stored locally or similar), file decryption 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, note that backup files must be stored on an unplugged external storage or remote server (e.g., Cloud). If not, the malware encrypts backups as well.

How did ransomware infect my computer?

Ransomware-type viruses are proliferated in various ways, however, the most popular are spam emails (infectious attachments), peer-to-peer (P2P) networks (torrents, eMule, and so on), third party software download sources (free file hosting websites, freeware download websites, etc.), fake software updaters, and trojans. Spam emails often contain malicious attachments (e.g., JavaScript files, MS Office documents, and others) that, once opened, stealthily download and install malware. P2P networks and other unofficial download sources proliferate malware by presenting it as legitimate software. Users are tricked into downloading and installing malware. Fake updaters exploit outdated software bugs/flaws or download ransomware rather than software updates. Trojans are the simplest ones - they merely open "backdoors" for high-risk malware to infiltrate the system. Ultimately, the main reasons for computer infections are poor knowledge and careless behavior.

How to protect yourself from ransomware infections?

To prevent ransomware infections, be very cautious when browsing the Internet. Never open files received from suspicious email addresses. These emails should be deleted with out reading. Furthermore, download your applications only from official/certified sources, using direct download links (third party downloaders/installers often include rogue applications). Furthermore, keep installed software up-to-date, however, since criminals proliferate malware via fake updaters, we recommend using implemented update features or tools provided by the official developer. Having a legitimate anti-virus/anti-spyware suite installed on your computer is also paramount. The key to computer safety is caution.
