This is an article that provides specific details on .KEYPASS files virus as well as a step-by-step removal followed by alternative data recovery approaches.
The so-called .KEYPASS files virus is a ransomware threat of unknown origin. As a typical data locker ransomware it plagues computer systems with the primary purpose to encode important files stored on their drives and enable hackers to blackmail victims into paying a ransom for a decryption key. Files corrupted by this threat are renamed with the distinctive extension .KEYPASS. The access to their data is restricted due to modifications of their code. Upon encryption a ransom message kept in the file !!!KEYPASS_DECRYPTION_INFO!!!.txt appears on the screen to demand a ransom payment of $300.

.KEYPASS Files Virus – Distribution
Security researchers detected that ongoing campaigns are spreading .KEYPASS ransomware payload worldwide. The infection code of .KEYPASS files virus may be spread with the help of malspam e-mail campaigns. E-mails used for malicious purposes usually contain one or more of the following components:
A link that lands on compromised web page set to download and execute the infection file directly on the PC.
A malicious file attachment masked as a legitimate document and uploaded in a .rar or .zip archive. Such a file could be set to evade detection and this way tricks you into allowing the ransomware to start on your PC.
As reported by users infected by .KEYRASS ransomware some of the products uploaded on the malicious website cracksfiles.com are also set to distribute the infection files of the threat. Eventually, once opened on a computer, files downloaded by this website infect it with the ransomware. The bad news is that this website is likely to be just one of many other unknown compromised websites that distribute .KEYPASS crypto virus.
In addition, fake software installers, fake update notifications, compromised software setups, files shared on forums and other techniques may download and activate the ransomware module.
.KEYPASS Files Virus – Infection Overview
An infection with .KEYPASS files virus leads to corrupted system settings and data encryption. Once the ransomware payload is executed on the system it initiates a sequence of malicious operations that enable it to complete the attack to its very end.
When loaded for the first time on the computer .KEYPASS files virus creates a copy of its executable file and places it in the following folder:
%AppData%
Then it launches the newly created file and deletes the initial file version from the original location. The ransomware is also likely to create or drop additional malicious files on the system. And there are several other folders that may store associated malicious files:
%AppData%
%Local%
%LocalLow%
%Roaming%
%Temp%
%Windows%
Once all malicious files are established the ransomware is ready to implement some changes that ensure its persistent presence on the system. These changes mostly affect the registry sub-keys Run and RunOnce. This could be explained by the fact that these keys manage the automatic execution of all essential files and objects that support the normal system load on its start. By manipulating their functionalities .KEYPASS virus takes the advantage to execute automatically its malicious files on each system start. Which in turn leads to the corruption of all files created before the last system shut down.
After all infection stages are competed the ransomware drops a file called !!!KEYPASS_DECRYPTION_INFO!!!.txt on the device. This file contains a ransom message left by hackers and all it reads is:
Attention!
All your files, documents, photos, databases and other important files are encrypted and have the extension: .KEYPASS The only method of recovering files is to purchase an decrypt software and unique private key.

You can do this with the help of the removal guide at the end. It presents steps on how to clean all harmful files from the system and how to potentially restore some of the encrypted files.
.KEYPASS Files Virus – Data Encryption Process
The primary purpose of .KEYPASS crypto virus alike each other data locker ransomware is data encryption. When it reaches this stage of the infection the ransomware triggers its built-in encryption module that uses the symmetric algorithm AES-256 to change parts of the original code of target files.
This stage begins with a scan of predefined system drives for target types of files and ends with the corruption of all files that match all parameters set in the code. As a result, the access to valuable files remains restricted until an efficient recovery tool reverts their original code. All of the following types of data may be encrypted by .KEYPASS files virus:
Audio files
Video files
Document files
Image files
Backup files
Banking credentials, etc
The analysis of threat’s samples reveal that files stored in the following folders remain untouched and safe:
C:\Windows\
C:\Program Files \Mozilla Firefox\
C:\Program Files\Internet Explorer\
C:\Program Files\Google\
D:\Windows\
D:\Program Files\Internet Explorer\
D:\Program Files\Mozilla Firefox\
D:\Program Files\Google\
In fact, the name of this ransomware is a derivative of the distinctive extension it uses to mark corrupted files – .KEYPASS. An additional impact caused by the threat may be the deletion of Shadow Volume Copies from the Windows operating system. This happens after the following command is run in the command prompt pannel:
→vssadmin.exe delete shadows /all /Quiet
With this command, the ransomware aims to eliminate one of the prominent ways of data recovery. Happily, there are other alternative methods that may help you to restore a few to all of your .KEYPASS files. Find some of them int he guide that follows.

4. Try to Restore files encrypted by .KEYPASS Files Virus
Try to Restore Files Encrypted by .KEYPASS Files Virus
Ransomware infections and .KEYPASS Files Virus aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
