Dirty App Removal: MAGA Ransomware

The digital world is constantly under attack by new and evolving malware. One of the latest threats to emerge is MAGA ransomware, a strain from the notorious Dharma family. This ransomware encrypts victims’ files, leaves behind ransom notes, and demands payment in exchange for file recovery. Understanding how MAGA works and how to protect yourself is critical in today’s cyber landscape.

What Is MAGA Ransomware?

MAGA ransomware is designed to block access to files by encrypting them, leaving victims with a stark choice: pay a ransom or lose their data forever. It doesn’t stop at file encryption—it renames files and leaves ransom notes in two formats: a pop-up window and a text file named “MAGA_info.txt”.

When it renames files, MAGA appends the victim’s unique ID, an attacker’s email, and the “.MAGA” extension to the file name. For example, a file named “1.jpg” becomes “1.jpg.id-9ECFA84E.[MAGA24@cyberfear.com].MAGA”.

How MAGA Delivers Its Message

The ransom note explains that the victim’s files are encrypted and reassures them that recovery is possible. However, this promise comes with conditions: victims must contact the attacker via the provided email address (MAGA24@cyberfear.com) and include their unique ID. A backup email (MAGA24@tuta.io) is also listed for cases where there’s no response within 24 hours. The attackers warn against seeking third-party help, aiming to dissuade victims from exploring alternative recovery methods.

The MAGA Ransomware ransom note reads like the following:

MAGA
YOUR FILES ARE ENCRYPTED
Don’t worry, you can return all your files!
If you want to restore them, write to the mail: MAGA24@cyberfear.com YOUR ID –
If you have not answered by mail within 24 hours, write to us by another mail:MAGA24@tuta.io
ATTENTION
MAGA does not recommend contacting agent to help decode the data

How Does MAGA Work?

As a member of the Dharma ransomware family, MAGA uses several sophisticated tactics to maximize damage. It encrypts both local and network-shared files, disables firewalls, and deletes Volume Shadow Copies to block easy recovery. To ensure persistence, it copies itself to the %LOCALAPPDATA% folder and adds entries to Run keys, allowing it to launch every time the system starts. MAGA may also collect location data and exclude specific directories from encryption.

Why Paying the Ransom Is Risky

While paying the ransom might seem like a quick solution, it’s a risky gamble. There’s no guarantee the attackers will provide a decryption tool, leaving victims out of pocket and still unable to access their files. If backups or third-party decryption tools are unavailable, recovery can be challenging. That’s why experts strongly advise against paying the ransom and instead recommend focusing on prevention and immediate malware removal.

How Does Ransomware Like MAGA Spread?

MAGA spreads through several common methods, including vulnerable RDP (Remote Desktop Protocol) services, phishing emails with malicious links or attachments, and pirated software. Other potential infection sources include software vulnerabilities, malicious advertisements, deceptive websites, unreliable downloads (like from P2P networks or third-party app stores), and infected USB drives.

Protecting Yourself from Ransomware Attacks

To minimize your risk of ransomware infection, follow these essential security practices:

• Only download apps and files from trusted sources like official websites or app stores.
• Avoid using pirated software or cracking tools, as they often carry hidden malware.
• Be cautious with unexpected emails, especially those containing attachments or links from unknown senders.
• Stay away from suspicious pop-ups, ads, and websites.
• Regularly update your operating system and software to patch vulnerabilities.
• Use a reliable anti-malware program to scan and protect your system from threats.

If your system is already infected with MAGA, immediately run a scan using a trusted and updated anti-malware program to remove the ransomware and prevent further data loss.

MAGA ransomware is a dangerous reminder of how vital cybersecurity measures are in protecting personal and business data. By staying vigilant, keeping regular backups, and using robust security software, you can reduce your chances of falling victim to ransomware attacks. Prevention is your best defense in the battle against evolving cyber threats.
