How to remove DiskStation Security Ransomware and decrypt your files

What is DiskStation Security Ransomware

DiskStation Security Ransomware is a type of malware specifically targeting Synology NAS (Network Attached Storage) devices, which are often used for storing large amounts of data, including backups and personal files. The main purpose of this ransomware, like others, is to encrypt files on the infected system and demand a ransom from the victim in exchange for the decryption key. The file extensions targeted by DiskStation Security Ransomware are not detailed in the provided search results. However, ransomware generally targets a wide range of file types, especially those associated with important documents, images, videos, and databases. The encryption method used is also not specified, but AES (Advanced Encryption Standard) is commonly employed by ransomware for its robustness. After encryption ransomware adds random extension to files. Upon successful encryption of files, ransomware typically leaves a ransom note (!!Read Me!!.txt) on the desktop or within affected directories. This note contains instructions for the victim on how to pay the ransom and often includes threats of data destruction or exposure if the demands are not met.

There is no mention of specific decryption tools for DiskStation Security Ransomware in the search results. Generally, decryption tools are only available if security researchers have managed to crack the ransomware’s encryption or if the attackers themselves release the keys. In the absence of a decryption tool, the primary method to recover files is to restore from backups that were not affected by the ransomware. Other alternative is to use file-recovery software, like the one recommended below in the article. It can recover (not decrypt) some of the data hit by the ransomware. To prevent ransomware infections on Synology NAS devices, users should:

• Use strong, unique passwords and enable two-factor authentication.
• Regularly update the NAS software to patch vulnerabilities.
• Enable the firewall and limit public port access to essential services.
• Use Synology’s built-in security features, such as Secure SignIn and Antivirus Essential.
• Regularly back up data following the 3-2-1 backup strategy (three copies of data, on two different media, with one copy offsite).

How DiskStation Security Ransomware infects computers

Ransomware typically infects computers and devices through various methods, including phishing emails, malicious websites, and exploiting vulnerabilities in software. For NAS devices like those from Synology, attackers may use brute-force attacks to guess weak passwords or exploit unpatched vulnerabilities to gain access. Once inside the network, the ransomware can move laterally, targeting backups and other critical data.

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. DiskStation Security 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.
