Cipher (Proton) Ransomware: Another Player in Cyber Extortion

Ransomware attacks are one of the most pressing concerns in the cybersecurity world, with new variants emerging regularly. One such variant, Cipher (Proton) Ransomware, is yet another player in the field. Like other ransomware families, Cipher (Proton) is designed to encrypt victims' files and demand payment for their decryption. Here, we will explore what Cipher (Proton) Ransomware is, how it operates, and what it ultimately seeks.

What Is Cipher (Proton) Ransomware?

Cipher (Proton) ransomware belongs to the larger Proton ransomware family, a notorious strain of malware that targets users' files for encryption. Once it infiltrates a system, Cipher Ransomware begins its malicious work by encrypting various file types and modifying their names. Victims will find their files appended with the attackers' email address and the extension ".cipher." For instance, a file originally named "document.pdf" may appear as "document.pdf.[watchdogs20@tuta.io].cipher" after encryption.

The next stage of the attack involves delivering ransom notes to the victim. These notes are displayed in several places, including a full-screen message before the login screen, the desktop wallpaper, and a text file named "#Read-for-recovery.txt." Their brevity makes Cipher (Proton) Ransomware's notes different from other ransomware. Unlike traditional ransom notes that detail the encryption process and instructions for decryption, Cipher's messages simply urge the victim to contact the attackers without providing much context.

Check out the note below:

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

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

What Does Ransomware Do?

Ransomware is malicious software that locks a victim's files by encrypting them, rendering them inaccessible until a ransom is paid. Attackers often use strong encryption algorithms, making it nearly impossible for the victim to regain access to their data without the decryption key. Of course, the attackers hold the key, and they offer to release it once a ransom payment is made, typically in cryptocurrency to maintain anonymity.

Cipher (Proton) ransomware operates on this same principle. The victim is left in a precarious position once the ransomware encrypts a user's files. Without backups or the means to decrypt the files themselves, they are at the mercy of the attackers. The unfortunate truth is that, in many cases, the attackers may not provide the promised decryption key even after paying the ransom. This can leave victims with both financial losses and permanently locked files.

The Goals of Cipher (Proton) Ransomware

The primary goal of Cipher (Proton) ransomware, like other ransomware variants, is financial gain. The attackers seek to extort money from their victims by creating a situation in which the victim's data is inaccessible. They leverage this power to demand ransom payments, often ranging from a few hundred to several thousand dollars. The ransom demand amount typically depends on the target; individuals might face smaller amounts, while businesses and institutions are asked for significantly larger sums.

However, cybersecurity experts strongly advise against paying the ransom. Not only is there no guarantee that the attackers will provide the decryption key, but paying also funds further criminal activity. Supporting ransomware operators perpetuates the cybercrime cycle, allowing them to continue targeting new victims. Furthermore, law enforcement and cybersecurity organizations emphasize that decryption is often impossible without the involvement of the criminals, except in rare cases where the ransomware is poorly constructed.

How Cipher (Proton) Ransomware Spreads

Cipher (Proton) Ransomware spreads through various malicious distribution techniques, many of which rely on human error and manipulation. Cybercriminals commonly use phishing emails, where malicious files or links are embedded within seemingly legitimate messages. Once the recipient opens the attachment or clicks the link, the ransomware is executed on their system, encrypting files in a matter of moments.

In addition to phishing attacks, ransomware like Cipher (Proton) can be spread via fake software updates, bundled with pirated software, or malicious advertisements. Some versions of ransomware are also known to propagate through local networks or removable devices like USB drives, infecting multiple systems within an organization or household.

Once the ransomware has infiltrated a system, it begins its encryption process. With Cipher (Proton), the victim's files are renamed, and the ".cipher" extension is added, signaling that they have been encrypted and are no longer usable. The ransom notes left by Cipher ransomware provide the victim with instructions on contacting the attackers, but they offer little insight into the encryption process or the cost of the ransom itself.

Why Backups Matter

For Cipher (Proton) Ransomware victims, backups are the only reliable way to restore files. However, these backups must be stored on separate devices or servers, away from the infected machine, as ransomware can often target connected or mapped drives. Those without backups may face the tough choice of losing their files permanently or negotiating with cybercriminals.

Maintaining regular, up-to-date backups in multiple locations is a crucial defense against ransomware attacks. Remote servers, cloud storage, and unplugged external drives are all viable options for securing valuable data. By keeping backups in diverse locations, victims can recover their files without relying on the whims of cyber criminals.

The Bigger Picture: A Growing Threat

Cipher (Proton) Ransomware is just one example of a long line of ransomware attacks targeting individuals and organizations. Other recent variants, such as Terminator, Bixi, and ScRansom, operate similarly—encrypting files and demanding payment. While the methods and techniques may vary slightly between ransomware families, the ultimate goal remains the same: to extort money from the victim in exchange for restoring access to their files.

As ransomware continues to evolve, so too must the strategies used to defend against it. By remaining vigilant, cautious, and proactive in securing backups, users can protect themselves from falling victim to ransomware like Cipher (Proton). Preparedness is the best defense in a digital world rife with cyber threats.
