How to remove Trial_recovery Ransomware and decrypt .-encrypted files

What is Trial_recovery Ransomware

Trial_recovery Ransomware is a malicious software designed to encrypt valuable files on an infected computer and demand a ransom for their decryption. This ransomware specifically targets various file types, locking them behind a complex encryption process and renaming them with a distinctive pattern. Files affected by this malware will be renamed following the trial-recovery.[random_string].[random_string].-encrypted pattern, drastically altering their original names and extensions, so .-encrypted extension is one of the signs of infection with this particular threat. The encryption uses a strong cryptographic algorithm that is often unbreakable without the unique decryption key held by the attackers. Victims will notice that their files, once accessible, are now inaccessible and are presented with a changed extension and name. Upon successful encryption, Trial_recovery Ransomware generates a ransom note titled how_to_decrypt.txt, which is typically placed on the infected system’s desktop.

The note informs the victims that their files have been encrypted and their confidential data has been stolen, pushing them to contact the attackers via email or Telegram to negotiate the ransom payment. Unfortunately, there are no publicly available decryption tools for this ransomware at the moment, making file recovery challenging without the decryption key. Thus, decrypting .-encrypted files without the attacker’s cooperation is generally impossible. It is crucial to avoid paying the ransom, as it does not guarantee file recovery and further supports criminal activity. Instead, victims should focus on removing the ransomware from their system and seek advice from cybersecurity professionals on potential data recovery options.

How Trial_recovery Ransomware infects computers

Trial_recovery Ransomware infiltrates computers primarily through phishing and social engineering techniques. Cybercriminals often disguise malicious files as legitimate email attachments or links, tricking users into downloading and executing them. These files can take various forms, including executables, archives, and documents embedded with malicious macros. In addition to email-based attacks, ransomware can spread through compromised websites, malicious ads, and fake software updates. Once executed, the ransomware encrypts the victim’s files and displays a ransom note, demanding payment for decryption. To mitigate such threats, users should exercise caution with unsolicited emails, keep their software up-to-date, and employ reputable security solutions.
