What is Cipher (Proton) Ransomware

Cipher (Proton) Ransomware is a notorious cyber threat that belongs to the Proton ransomware family, which primarily targets users by encrypting their valuable data and demanding ransom for decryption. Upon infection, this malware appends the .cipher extension to the filenames of encrypted files, marking them distinctly. For example, a file initially named document.jpg would be modified to document.jpg.[watchdogs20@tuta.io].cipher, highlighting the attacker’s contact email. Using asymmetric encryption, Cipher (Proton) employs sophisticated cryptographic algorithms that render files unusable without a decryption key that only the attackers possess. Once encryption completes, the ransomware generates ransom notes in multiple forms: a full-screen message before the log-in screen, desktop wallpaper alterations, and text files named #Read-for-recovery.txt. These notes evade detailing the encryption process and solely urge victims to contact the cyber criminals via email for further instructions.

#Read-for-recovery.txt
Email 1:
watchdogs20@tuta.io
Email 2:
watchdogs20@cock.li
Send messages to both emails at the same time
So send messages to our emails, check your spam folder every few hours
ID: -
If you do not receive a response from us after 24 hours, create a valid email, for example, gmail,outlook
Then send us a message with a new email

Unfortunately, decryption tools for Cipher (Proton) Ransomware are currently unavailable due to the complexity and strength of the used encryption algorithms. This absence of dedicated decryption tools leaves victims with limited options for data recovery. Attempting to decrypt .cipher files without paying the ransom typically turns futile, as successful decryption necessitates the keys held by the attackers. Moreover, even if victims decide to pay, there is no guarantee of receiving the decryption tools, and it is discouraged to comply with the ransom demands as it fosters illegal activities. The recommended course is to remove the infection immediately to prevent further data encryption and restore any affected files from previously created backups stored securely offline. Employing reliable antivirus software for malware removal is also essential. For future protection, maintaining updated and regular backups across multiple storage solutions and enhancing cybersecurity practices are crucial to mitigate the impact of such ransomware attacks.

How Cipher (Proton) Ransomware infects computers

Cipher (Proton) Ransomware primarily infiltrates computers through phishing and social engineering tactics. Cybercriminals often disguise the ransomware as legitimate files or bundle it with seemingly harmless content, such as email attachments, malicious links, or downloads from untrustworthy sources like torrent websites and free file-hosting services. Once the victim executes the infected file, the ransomware is installed and begins encrypting the user’s data. Additionally, some variants exploit vulnerabilities in outdated software or use malicious advertisements to silently download the ransomware onto the target system. The ransomware also has the potential to spread across local networks and infect external storage devices, amplifying its impact.
