KEYPASS ransomware removal instructions

What is KEYPASS?

KEYPASS is a high-risk ransomware-type virus that stealthily infiltrates the system and encrypts most stored data. We suspect this malware to be an updated variant of another ransomware infection called STOP. During encryption, KEYPASS appends filenames with the ".KEYPASS" extension (e.g., "sample.jpg" is renamed to "sample.jpg.KEYPASS"). Once encrypted, data immediately becomes unusable. Following successful encryption, KEYPASS generates a text file ("!!!KEYPASS_DECRYPTION_INFO!!!.txt") and places a copy in every existing folder.

As usual, the new text file contains a message informing victims of the encryption, and that files can only be restored using a decryption tool together with a unique key. Unfortunately, this information is accurate. Although it is currently not confirmed whether KEYPASS uses symmetric or asymmetric cryptography, each victim requires a unique key. As mentioned, restoring data without a key is impossible. Therefore, cyber criminals hide the keys on a remote server and make ransom demands for their release - to restore files, victims must pay $300. It is also stated that payment must be submitted within 72 hours following encryption, otherwise restoring data becomes impossible. As compared to other ransomware, the cost of KEYPASS decryption is not high - in most cases, the size of ransom fluctuates between $500 and $1500. Regardless of the cost, do not pay. Research shows that cyber criminals often ignore victims once payments are submitted. Thus, paying typically gives no positive result and users are scammed. We strongly advise you to ignore all requests to contact these people or pay any ransoms. Unfortunately, there are no tools capable of cracking this ransomware's encryption and restoring compromised files free of charge. Therefore, you can only restore everything from a backup.

KEYPASS is virtually identical to dozens of other ransomware-type viruses, such as Paradise, CryptoLite, Scarab, Excuses, and many others. Although they have different developers, the behavior of these viruses is identical - all encrypt data and make ransom demands. In most cases, ransomware-type viruses have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most use RSA, AES, and other algorithms that generate unique keys. Therefore, unless the virus is not fully developed or has certain bugs/flaws, restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. Ransomware-type viruses present a strong case for maintaining regular data backups. Bear in mind, however, that these files must be stored on a remote server or unplugged storage device. If not, malware encrypts them together with regular data.

How did ransomware infect my computer?

Developers typically proliferate KEYPASS using fake software activation tools (cracks), such as KMSpico. Once opened, these tools immediately infiltrate KEYPASS into the system, however, ransomware-type viruses are often distributed using spam emails (infectious attachments), unofficial software download sources (free file hosting websites, freeware download sites, peer-to-peer [P2P] networks, and similar), fake software update tools, and trojans. Spam emails are delivered with malicious attachments (in most cases MS Office documents) which, once opened, download and install ransomware. Third party download sources present malicious executables as legitimate software, thereby tricking users into downloading and installing viruses. Fake updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates. Trojans simply open "backdoors" for other malware to infiltrate the system.

How to protect yourself from ransomware infections?

Lack of knowledge and careless behavior are the main reasons for computer infections - caution is the key to safety. Therefore, pay close attention when browsing the Internet and downloading/installing software. We strongly recommend that you think twice before opening email attachments. Irrelevant files and those received from suspicious email addresses should never be opened. In addition, download software from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus these tools should not be used. It is also important to keep installed software up-to-date, however, this should be achieved through implemented functions or tools provided by the official developers only. Having a reputable anti-virus/anti-spyware suite installed and running is paramount. If your computer is already infected with KEYPASS, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

4. In the opened window, click "Next".

restore system files and settings

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 KEYPASS ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining KEYPASS 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 KEYPASS 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.

Restoring files encrypted by CryptoDefense

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 regain control of the files encrypted by KEYPASS, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

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 KEYPASS 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.

Controll Folder Access

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:
