What is Kiwm Ransomware
If your files became unavailable, unreadable, and got .kiwm extensions it means your computer is infected with Kiwm Ransomware (variation of STOP Ransomware or as it is, sometimes, called DjVu Ransomware). It is a malicious program that belongs to the group of ransomware viruses. This particular version was released in the beginning of April 2023. This virus can infect almost all modern versions of the operating systems of the Windows family, including Windows 7, Windows 8, Windows 10 and the latest Windows 11. The malware uses a hybrid encryption mode and a long RSA key, which virtually eliminates the possibility of selecting a key for self-decrypting files. Like other similar viruses, the goal of Kiwm Ransomware is to force users to buy the program and key needed to decrypt files that have been encrypted. The version, that is under research today, is almost identical to the previous ones, except for new e-mails used for contacting malefactors and new extensions added. Here is an example of the ransom note (_readme.txt), that the virus leaves:

As you can see, you have to pay hundreds of dollars with no guarantee of receiving the solution from hackers. Is it possible to decrypt .kiwm files without paying the ransom? Here is how encryption of Kiwm Ransomware works: to determine which key to use for encryption, the malware tries to establish a network connection with its command server. The virus transmits information about the infected computer to the server and receives the encryption key from it. In addition, the command server can transmit additional commands and modules to the virus that will be executed on the victim’s computer. If the data exchange with the command server was successful, then the virus uses the received encryption key (online key). In this case, unfortunately, decryption is impossible. This key is unique for each infected computer. If Kiwm Ransomware could not establish a connection with its server, then a fixed key (offline key) will be used to encrypt the files. This key is the same for all infected computers. Moreover, this key can be determined, which gives hope to the victims, in some cases, to decrypt the files infected with the virus. Stellar Data Recovery Professional is one of the best file-recovery tools and, if used properly, may recover copies and duplicates of encrypted files, that were removed prior to infection. The only option for a successful 100% recovery is existing backups. Try to implement solutions given on this page to remove Kiwm Ransomware and decrypt .kiwm files, and if you won’t succeed preserve encrypted files for a possible solution in the future.
How Kiwm Ransomware infected your computer
Kiwm Ransomware is a variant of the STOP/Djvu Ransomware family, which is known for its aggressive distribution and encryption techniques. Here are some of the common ways in which Kiwm Ransomware can infect a computer:
- Malicious email attachments: Cybercriminals often use phishing emails to trick users into downloading and executing malware-laden attachments. These emails may appear to be from a legitimate source and may urge the recipient to open the attachment.
- Software cracks and keygens: Users who download and install software cracks or keygens from unauthorized sources are at risk of infecting their systems with malware. Kiwm Ransomware may be bundled with such cracked software, and when the user runs the installer, the malware is installed alongside.
- Fake software updates: Cybercriminals may create fake software updates for popular applications and post them on malicious websites. When a user downloads and installs such updates, they may inadvertently install Kiwm Ransomware or other malware.
- Exploits: Kiwm Ransomware may exploit vulnerabilities in software or operating systems to gain access to a user’s computer. Exploits can be delivered through various means, such as malicious websites, email attachments, or compromised software.

Virus modifies “hosts” file to block Windows updates, downloading antivirus programs, and visiting sites related to security news or offering security solutions. Kiwm Ransomware comes along with AZORult trojan, which was initially created to steal logins and passwords. The process of infection also looks like installing Windows updates, the malware shows a fake window, that mimics the update process.
It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. Kiwm Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. Can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers. The virus assigns a certain ID to the victims, which is used to name those files and supposedly to send a decryption key. Great tools to protect against Kiwm Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.

How to protect computer from viruses, like Kiwm Ransomware, in future
1. Get special anti-ransomware software
Use ZoneAlarm Anti-Ransomware
Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.
2. Back up your files
As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Kiwm Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.
3. Do not open spam e-mails and protect your mailbox
Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
