How to remove RDP (Chaos) Ransomware and decrypt .encrypted files

What is RDP (Chaos) Ransomware

RDP (Chaos) Ransomware is a malicious program that belongs to the Chaos ransomware family. It is designed to encrypt data on infected computers and subsequently extort victims for payment in exchange for the decryption key. Once launched on a computer, the ransomware scans for files and, upon locating them, encrypts these files and appends a new extension, .encrypted, to their filenames, making the original files inaccessible. For instance, a file named document.docx will be renamed to document.docx.encrypted. After the successful encryption of files, the ransomware alters the victim’s desktop wallpaper and drops a ransom note titled read_it.txt. This note informs the victim that their files have been encrypted and provides instructions on how to restore the affected data, typically demanding payment in cryptocurrency such as Bitcoin, Litecoin, Ethereum, or Solana.

Ransom notes left by RDP (Chaos) Ransomware specify a ransom amount, which in this case is $50, and offer an email contact for victims to communicate with the attackers. Despite the relatively low ransom demand, paying is highly discouraged since there is no guarantee that the perpetrators will provide the decryption key, and compliance only fuels further criminal activities. Unfortunately, no known decryption tools are available to undo the damage caused by this ransomware, given the complexity and robustness of the encryption algorithms it employs. Therefore, if your files have been locked with the .encrypted extension, the best recourse is to restore your data from a previously created backup, assuming one is available. It’s crucial to equip your system with reliable anti-malware software to detect and remove RDP (Chaos) Ransomware and other similar threats in the future.

How RDP (Chaos) Ransomware infects computers

RDP (Chaos) Ransomware primarily infiltrates computers through Remote Desktop Protocol (RDP) vulnerabilities, often exploiting weak or compromised RDP credentials. Cybercriminals leverage brute-force attacks or use stolen credentials to gain unauthorized access to systems. Once inside, they deploy the ransomware payload, which then begins encrypting files on the affected machine. Additionally, this malware can spread through phishing emails containing malicious attachments or links, drive-by downloads from compromised websites, and even through unpatched software vulnerabilities. Preventing such infections requires robust security measures, including strong, unique passwords, multi-factor authentication, regular software updates, and vigilant email security practices.

Download RakhniDecryptor

There is no purpose to pay the ransom because there is no guarantee you will receive the key, but you will put your bank credentials at risk.

Dr.Web Rescue Pack

Famous antivirus vendor Dr. Web provides free decryption service for the owners of its products: Dr.Web Security Space or Dr.Web Enterprise Security Suite. Other users can ask for help in the decryption of .encrypted files by uploading samples to Dr. Web Ransomware Decryption Service. Analyzing files will be performed free of charge and if files are decryptable, all you need to do is purchase a 2-year license of Dr.Web Security Space worth $120 or less. Otherwise, you don’t have to pay.

If you are infected with RDP (Chaos) Ransomware and removed from your computer, you can try to decrypt your files. Antivirus vendors and individuals create free decryptors for some crypto-lockers. To attempt to decrypt them manually, you can do the following:

How to protect computer from viruses, like RDP (Chaos) 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. RDP (Chaos) 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.
