MIRROR Ransomware

Upon thoroughly analyzing potential malware threats, researchers have conclusively identified MIRROR as a ransomware variant. The primary objective of the MIRROR threat is to encrypt files present on compromised devices. Additionally, it undertakes file renaming and issues two ransom notes—one in the form of a pop-up window and the other as a text file named 'info-MIRROR.txt.'

The MIRROR Ransomware employs a specific naming convention for files it encrypts, appending the victim's ID, 'tpyrcedrorrim@tuta.io' email address, and '.Mr' extension. For example, it transforms '1.pdf' into '1.pdf.id-9ECFA74E.[tpyrcedrorrim@tuta.io].Mr,' and '2.png' becomes '2.png.id-9ECFA74E.[tpyrcedrorrim@tuta.io].Mr,' and so forth. This particular threat has been categorized as a variant within the Dharma Ransomware family.

The MIRROR Ransomware goes Beyond File Encryption

In addition to encrypting files, MIRROR employs strategic measures to compromise the targeted system's security further. One such tactic involves disabling the firewall, thereby heightening the system's vulnerability to the malicious activities orchestrated by the ransomware. Additionally, MIRROR takes deliberate actions to erase the Shadow Volume Copies, effectively eliminating potential restore points and hindering recovery efforts.

MIRROR capitalizes on vulnerabilities within Remote Desktop Protocol (RDP) services as a primary vector for infection. This typically involves exploiting weak account credentials through methods like brute force and dictionary attacks. By leveraging these techniques, the ransomware gains unauthorized access to systems, particularly those with inadequately managed account security.

Furthermore, MIRROR exhibits the capability to extract location data, allowing it to discern the geographical context of the infected systems. Notably, it possesses the ability to exclude predetermined locations from its data extraction scope. Additionally, MIRROR incorporates persistence mechanisms, ensuring that it can maintain a foothold within the compromised system over an extended period.

Victims of the MIRROR Ransomware are Extorted for Money

The ransom note of the MIRROR Ransomware serves as a communication from the attackers to the victim, explicitly stating that all of the victim's files have undergone encryption. It outlines a potential avenue for file restoration, instructing the victim to initiate contact through a specified email address (tpyrcedrorrim@tuta.io) and providing a unique identifier.

As an alternative means of communication, the note also supplies another email address (mirrorrorrim@cock.li). Notably, the note strongly discourages the use of intermediaries for communication, citing potential risks such as overcharging, unjustified debit, and transaction rejection. The attackers assert their capability to provide encrypted data recovery services and offer guarantees, including a recovery demonstration involving up to three files to substantiate their proficiency.

Moreover, the ransom note issues a cautionary advisory to the victim, explicitly advising against renaming encrypted files. It also warns against attempting decryption through third-party software, emphasizing the potential consequences of permanent data loss or susceptibility to scams. The intent is to guide the victim on the safest course of action to maximize the chances of successful file recovery while minimizing potential risks.

Take Measures to Fortify Your Devices against Ransomware Infections

Ransomware poses a significant threat to the security of digital devices, with potential consequences ranging from data loss to financial extortion. Implementing proactive measures is crucial to fortify devices against such infections. Here are five effective steps users can take:

• Regularly Update Operating Systems and Software: Keeping operating systems and software up-to-date is vital, as updates often include security patches that address vulnerabilities. Regularly check for and apply updates to reduce the risk of ransomware exploiting known weaknesses.
•  Install and Maintain Security Software: Utilizing trustable security software gives an additional layer of defense against ransomware. Ensure the anti-malware program is regularly updated and conduct scheduled scans to detect and eliminate potential threats before they can compromise your device.
•  Exercise Caution with Email Attachments and Links: Ransomware often infiltrates systems through phishing emails containing malicious attachments or links. Use a lot of caution when opening emails from unknown senders, try not to click on suspicious links, and refrain from downloading attachments unless their legitimacy is verified.
•  Backup Data Regularly: Creating regular backups of essential data is a critical preventive measure. In a ransomware attack, recent backups allow users to restore their files without succumbing to extortion. Store backups on an external device or a secure cloud service.
•  Implement Network Security Measures: Strengthening network security can thwart ransomware attacks. Utilize firewalls and intrusion detection/prevention systems, employ unique and strong passwords for all devices and accounts, and consider segmenting networks to limit the potential impact of an infection on the entire system.

By adopting these measures, users can significantly enhance the resilience of their devices against ransomware, safeguarding their valuable data and maintaining the integrity of their digital environment.

The full text of the main ransom note left by the MIRROR Ransomware is:

'MIRROR
All your files have been encrypted!
Don't worry, you can return all your files!
If you want to restore them, write to the mail: tpyrcedrorrim@tuta.io YOUR ID 9ECFA84E
If you have not answered by mail within 12 hours, write to us by another mail:mirrorrorrim@cock.li
We strongly recommend that you do not use the services of intermediaries and first check the prices and conditions directly with us.The use of intermediaries may involve risks such as:
-Overcharging: Intermediaries may charge inflated prices, resulting in improper additional costs to you.
-Unjustified debit: There is a risk that your money may be stolen by intermediaries for personal use and they may claim that we did it.
-Rejection of the transaction and termination of communication: Intermediaries may refuse to cooperate for personal reasons, which may result in termination of communication and make it difficult to resolve issues.
We understand that data loss can be a critical issue, and we are proud to provide you with encrypted data recovery services. We strive to provide you with the highest level of confidence in our abilities and offer the following guarantees:
---Recovery demo: We provide the ability to decrypt up to three files up to 5 MB in size on a demo basis.
Please note that these files should not contain important and critical data.
Demo recovery is intended to demonstrate our skills and capabilities.
---Guaranteed Quality: We promise that when we undertake your data recovery, we will work with the utmost professionalism and attention to detail to ensure the best possible results.
We use advanced technology and techniques to maximize the likelihood of a successful recovery.
---Transparent communication: Our team is always available to answer your questions and provide you with up-to-date information about the data recovery process.
We appreciate your participation and feedback.
Attention!
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.'

The text file dropped by the MIRROR Ransomware contains the following message:

'all your data has been locked us

You want to return?

write email tpyrcedrorrim@tuta.io or mirrorrorrim@cock.li'
