InsaneCrypt ransomware removal instructions
What is InsaneCrypt?
Discovered by malware security researcher, Karsten Hahn, InsaneCrypt is ransomware-type malware that stealthily infiltrates the system and encrypts most stored files. In doing so, this virus appends filenames with the ".[firstname.lastname@example.org].insane" extension (e.g., "sample.jpg" is renamed to "sample.jpg.[email@example.com].insane"). From this point, using files becomes impossible. After successfully encrypting files, InsaneCrypt creates a text file ("How_decrypt_files.txt" or "note.txt"), placing it on the desktop. Other variant of this ransomware adds ..DEUSCRYPT extension to encrypted files, for example .[firstname.lastname@example.org].DEUSCRYPT. Updated variants add .[email@example.com].volcano extension to encrypted files.
The new text file contains a message encouraging victims to contact InsaneCrypt's developers (via an email address provided) if they want to decrypt their files. Users are provided with detailed instructions regarding decryption. InsaneCrypt uses a type of encryption that generates a unique decryption key. Restoring files without this key is impossible. Therefore, criminals hide it on a remote server, allowing them to make ransom demands for its release - users must pay a certain fee to receive the key. The cost is currently unconfirmed, but typically fluctuates between $500 and $1500 in Bitcoins (or other cryptocurrency). Despite these demands, cyber criminals are likely to ignore victims, once the payments are submitted. Therefore, in most cases, paying does not deliver any positive result - users are scammed. Therefore, never attempt to contact these people or send any money. Fortunately, Michael Gillespie has developed a tool to restore files free of charge (download link). Therefore, there is no need to pay. If, however, your computer has been infected with other (undecryptable) ransomware, the only solution is to restore everything from a backup.

InsaneCrypt2 is virtually identical to MoneroPay, GHOST ARMY, PLANETARY, and dozens of other ransomware-type viruses. Note that although these viruses are developed by different cyber criminals, all have identical behavior - they encrypt data and make ransom demands. They typically have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most ransomware employs algorithms that generate unique decryption keys (e.g., AES, RSA, and so on). In such cases, restoring files manually without involvement of developers (contacting these people is not recommended) is impossible, unless the malware is not fully developed or has certain bugs/flaws (for instance, the key is stored locally, hard-coded, or similar). For these reasons, ransomware-type viruses present a strong case for maintaining regular data backups, however, it is important to store your backup files on an unplugged external storage or remote server (such as Cloud), otherwise the malware encrypts them as well.
How did ransomware infect my computer?
|Threat Type||Ransomware, Crypto Virus, Files locker|
|Symptoms||Can't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate InsaneCrypt virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
The key to computer safety is caution. Therefore, pay close attention when browsing the Internet. Never open files received from suspicious email addresses - these emails should be deleted without reading. Furthermore, your applications should be downloaded from official sources only and, preferably, using a direct download link. Third party downloaders/installers are often used to proliferate malware (rogue apps). Therefore, these tools should never be used. Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite, however, since fake updaters are used to proliferate malware, use implemented update tools or tools provided by the official developer.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the InsaneCrypt ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining InsaneCrypt ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of InsaneCrypt are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as InsaneCrypt ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
