MedusaLocker, also known as Medusa ransomware, is commonly delivered to a victim’s network through email attachments, links, or exploits in the Remote Desktop Protocol (RDP). Its origins date back to 2019, and it is notorious for targeting both individuals and institutions.
Medusa ransomware, also known as MedusaLocker, is a malicious software designed to encrypt files on targeted Windows computers, rendering them inaccessible to users. The attackers then demand payment in cryptocurrency to provide the decryption key necessary for restoring access to the encrypted files.
Originating in 2019, MedusaLocker has gained notoriety for its widespread impact on both individuals and institutions. The ransomware is typically delivered through email attachments, links, or exploits in the Remote Desktop Protocol (RDP), showcasing its versatility in exploiting various attack vectors.
MedusaLocker presents itself under various aliases, including MedusaLocker, AKO Ransomware, AKO Doxware, and MedusaReborn. It has distinct variants, such as those displaying ransom notes in .txt or .html formats.
The symptoms of a Medusa ransomware infection include the sudden inaccessibility of files with encryption-related extensions (e.g., .docx, .pdf, .jpg), the appearance of ransom notes in affected directories, system and network slowdowns due to resource-intensive encryption processes, and the generation of unique encryption keys for each infected system, making decryption without payment challenging.
Sources of MedusaLocker infections include email attachments containing malicious payloads, malicious links in emails or other communication channels, exploitation of vulnerabilities in the Remote Desktop Protocol (RDP) for unauthorized access, drive-by downloads from compromised websites, and compromised software installers or updates used as delivery mechanisms for the ransomware.
If you suspect your system is infected with Medusa ransomware, immediate isolation of the affected device from the network is crucial to prevent further spread. It is advised to contact your IT security team or a professional cybersecurity firm for assistance. Attempting to decrypt files without professional guidance may result in permanent data loss. Preserving evidence, such as the ransom note and any communication from the attackers, is essential for potential law enforcement involvement.
Preventive measures against MedusaLocker include keeping software and operating systems up-to-date with the latest security patches, educating users about phishing tactics and the importance of not clicking on suspicious links or opening unexpected email attachments, restricting Remote Desktop Protocol (RDP) access, using strong, unique passwords for all accounts, implementing network segmentation to limit the potential impact of a ransomware infection, and regularly backing up critical data in offline or secured environments.

Do not attempt to decrypt files without professional guidance, as improper actions may lead to permanent data loss.
Preserve evidence by documenting the ransom note, any communication from the attackers, and any other relevant information for potential law enforcement involvement.
1. Keep software and operating systems up-to-date with the latest security patches.
2. Educate users about phishing tactics and the importance of not clicking on suspicious links or opening unexpected email attachments.
3. Restrict Remote Desktop Protocol (RDP) access and use strong, unique passwords for all accounts.
4. Implement network segmentation to limit the potential impact of a ransomware infection.
5. Regularly back up critical data and ensure backups are stored offline or in a secured environment.
