How to remove Duralock Ransomware and decrypt .duralock05 files

What is Duralock Ransomware

Duralock Ransomware is a type of malicious software identified by information security researchers as a significant threat. It belongs to the MedusaLocker ransomware family and is designed to encrypt data on infected computers, rendering files inaccessible to users. Once a computer is infected, Duralock encrypts the user’s files and appends a distinctive extension, .duralock05, to the filenames. This marks the files as encrypted and prevents users from accessing their content without the decryption key. Duralock Ransomware creates a ransom note named HOW_TO_BACK_FILES.html on the infected computer. This note typically contains instructions for the victim on how to pay a ransom to the attackers in exchange for the decryption key needed to unlock the encrypted files. This article features removal methods, removal tools and possible ways to decrypt encrypted files without negotiating with malefactors.

As of the information available, there is no mention of a free decryption tool specifically for Duralock Ransomware. Victims are often advised against paying the ransom, as this does not guarantee the recovery of encrypted files and may encourage further criminal activity. To prevent ransomware infections, users should regularly scan their systems with reputable antivirus software and remove any detected threats. It is also crucial to keep all software up to date, avoid using software cracking tools, and download files only from trusted sources. For recovery, if no decryption tool is available, victims may attempt to restore files from backups if they have been maintained and are uninfected. In some cases, data recovery professionals may offer services to help recover some data, but success is not guaranteed.
