Ransomware attacks have surged in recent years, becoming one of the most significant cybersecurity threats to individuals and organizations alike. Among the many variants of ransomware, Rajah has emerged as a particularly dangerous threat. Known for encrypting victims’ data and demanding payment in Bitcoin, Rajah ransomware can lead to significant financial and operational damage if not properly addressed.

What is Rajah Ransomware?
Rajah is a type of ransomware belonging to the Makop family, a well-known ransomware group notorious for targeting various organizations globally. Once Rajah infects a system, it encrypts files, making them inaccessible to the user, and appends a “.rajah” extension to the filenames. It then leaves behind a ransom note, instructing the victim to contact the attackers via email and make a Bitcoin payment for data decryption.
Key Features of Rajah Ransomware:
- File Encryption: Converts files to an unusable state by encrypting them using complex cryptographic algorithms.
- Extension Added: Files are renamed with the “.rajah” extension, e.g., “example.jpg” becomes “example.jpg.[victim ID].[[email protected]].rajah.”
- Ransom Note: A text file titled +README-WARNING+.txt is placed in every folder containing encrypted files, detailing how to contact the attackers.
The Behavior and Tactics of Rajah Ransomware
Once Rajah is executed on a system, it initiates an encryption process that targets a wide variety of file types including documents, images, videos, and databases. The encryption algorithm used by Rajah is highly sophisticated, ensuring that recovery without the decryption key is virtually impossible. This malware appends not only the .rajah extension but also adds a unique identifier and the email of the cybercriminals, allowing for easy identification by both victim and attacker.
Ransom Note Analysis:
The ransom note usually follows a predictable pattern:
- Victims are informed that their data has been encrypted.
- They are instructed not to use any third-party decryption or antivirus tools, claiming that such actions will render the files permanently corrupt.
- Payment must be made in Bitcoin, with instructions to purchase Bitcoin provided in the note.
- The victim is asked to contact the cybercriminals via email at [email protected].
This coercive message is designed to create a sense of urgency, pushing victims toward paying the ransom out of desperation.
How Rajah Ransomware Spreads?
Rajah ransomware spreads using multiple attack vectors, often relying on social engineering tactics that trick users into downloading or executing malicious files. The primary methods include:
- Phishing Emails: Victims receive emails with malicious attachments or links disguised as legitimate communication from trusted entities (e.g., service providers or companies like FedEx).
- Malvertising: Cybercriminals inject malicious code into seemingly legitimate online ads, leading to the automatic download of the malware.
- Drive-by Downloads: This occurs when users visit compromised websites, which stealthily download malware onto their systems.
- Trojan Injections: Rajah can also be delivered via trojanized software, where a seemingly benign program carries hidden malicious code.
- Peer-to-Peer File Sharing: Downloading software or media through torrents or file-sharing platforms can result in exposure to malware bundled with legitimate files.
Understanding Rajah’s Encryption Process
Rajah uses strong encryption techniques, which means once a file is encrypted, it cannot be restored without the corresponding decryption key. The specific algorithms employed are typically a combination of symmetric and asymmetric encryption, making the recovery process difficult.
- Symmetric Encryption: The same key is used for both encryption and decryption, which is shared by the cybercriminals.
- Asymmetric Encryption: Uses two keys—public for encryption and private for decryption. Only the attackers have the private key needed to decrypt the files.
Without paying the ransom, recovery is virtually impossible unless a flawed version of the ransomware is discovered or a decryption tool is developed by cybersecurity researchers.

Detection and Removal of Rajah Ransomware
Rajah is typically detected by multiple anti-malware solutions, but stopping the attack before encryption occurs is critical.
Detection Names:
Rajah is recognized under various names depending on the antivirus software:
- Avast: Win32
[Trj] - Kaspersky: HEUR
.Win32.Generic - Microsoft: Ransom
/Phobos.PB!MTB
Ransom Payment: Should You Pay?
Experts strongly advise against paying the ransom. While cybercriminals promise to deliver decryption keys in exchange for payment, there is no guarantee that they will follow through. In many cases, victims who pay the ransom do not receive the promised tools or keys, leading to permanent data loss.
Moreover, paying the ransom supports the illegal activities of cybercriminals and encourages further attacks. Therefore, it is essential to explore other recovery options before considering ransom payment.
How to Recover from a Rajah Ransomware Attack?
Once your system has been infected and your files encrypted, there are a few steps you can take:
- Restore from Backup: If you have a backup of your files stored on an external drive or cloud storage, you can restore the files without paying the ransom.
- Seek Professional Help: Contact cybersecurity professionals who specialize in ransomware recovery. They can assess whether any alternative recovery methods are available.
Preventing Future Ransomware Infections
Prevention is key to avoiding the devastating consequences of ransomware like Rajah. Here are several measures that can be taken to protect your data and systems:
Regular Software Updates:
Keeping your operating system and software up-to-date is crucial, as updates often include security patches that close vulnerabilities exploited by ransomware.
Antivirus and Anti-Malware Software:
Installing and maintaining reputable antivirus software with real-time scanning capabilities is essential. Programs like Combo Cleaner and GridinSoft offer robust ransomware protection and regularly update their databases to include the latest threats.
Email Vigilance:
Since phishing emails are a common vector for ransomware, always exercise caution when opening attachments or clicking on links in unsolicited emails. Avoid downloading attachments from unfamiliar sources.
Backup Your Data:
Regularly backing up your important files to an external hard drive or cloud storage service is a critical defense. Ensure that backups are stored in a location that is not connected to your system to prevent them from being encrypted in the event of an attack.
Use Strong Passwords:
Implement strong, unique passwords for all accounts and enable multi-factor authentication (MFA) wherever possible. This can prevent attackers from exploiting weak credentials to gain access to your systems.
Secure Remote Access (RDP):
Remote Desktop Protocol (RDP) is a common entry point for ransomware attacks. Restrict RDP access, use strong passwords, and enable MFA for additional security.
