What is cetori file virus? Cetori virus is also known as .cetori (STOP ransomware) and encrypts user files while asking for a ransom.

.cetori (STOP) virus is a new ransomware threat that is being sent to targets across the world. It is a complex ransomware that is distributed via various methods. The so-called Cetori virus can lead to many serious system issues. When the ransomware has completed running all of its modules, it will proceed with the file encryption making your files inaccessible. You will be left with .Cetori extension appended to all of your files, and a ransomware note and/or a lockscreen.

Our investigation shows that .cetori is another extension used by the STOP ransomware family. Since Cetori is a variant of STOP ransomware, a free decrypter could be updated by researchers after a week or so. In the meantime, we recommend that you save (back up) your .cetori encrypted files in a safe location, and remove the infection from your computer.

Cetori Virus (.cetori file) – Detailed Description

The Cetori virus is a dangerous new malware threat which is being spread by an unknown hacker or criminal group. As this is a new ransomware we do not know if it has specific targets or the perpetrators want to execute a global infection. As such it is very possible that the most popular distribution tactics are going to be used at once in order to select the most appropriate method.

Frequently the hackers choose to send out email-based phishing messages to the target recipients. The emails are sent in a manner which is very similar to the way SPAM messages are sent. They will manipulate the users into thinking that they have received a legitimate message from a popular company or service. A similar technique is the creation of special-built purpose scam sites that are designed to perform the same function. Interaction with their contents will lead to the .Cetori virus deployment.

In some cases the .Cetori virus can also be embedded in various file carriers. A popular example is the macro-infected documents: text files, presentations, databases and spreadsheets. As soon as they are opened the victims will be prompted to enable the built-in macros. If this is done the associated ransomware infection will be made. The other widely used technique is the creation of infected software installers. They are made by taking the setup packages of popular applications and modifying them with the .Cetori virus code. All data can be uploaded to file-sharing networks where both legitimate and pirate data is often uploaded. To facilitate a larger distribution the hackers may also embed the necessary code into browser hijackers — dangerous web browser extensions. The hackers will impersonate both developers or users. The posted descriptions often include promises of performance optimizations or the inclusion of new features. However as soon as they are installed the virus will be deployed automatically.

When the Cetori virus has finally been placed on a given computer it will start to execute its built-in sequence. It can follow the hardcoded instructions or only run certain commands depending on the local conditions. Usually attacks with ransomware like this virus will start with a data harvesting module. It is used to acquire information that can expose the identity of the victims (useful for other crimes) and to generate a report of the installed hardware components. This data can be used to create an unique ID that is assigned to each affected device.

When all dangerous .Cetori virus modules have finished running the actual file encryption will begin. Like other similar threats the actual file processing will be modeled on the typical ransomware virus action — a strong cipher will encrypt target user data according to a list of defined file types. Examples are the following: multimedia files, archives, backups, databases, archives and etc.

In the end the .Cetori virus will assign a custom extension to the processed files showing that the users cannot access them. A lockscreen or ransomware note will be activated in order to blackmail the users into paying the hackers a decryption fee.

Cetori Virus – Malicious Activities

The .Cetori ransomware is a cryptovirus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the lockscreen will launch an application frame which will prevent the users from interacting with their computers. It will display the ransomware note to the victims.

Once the Cetori virus infects your computer, it may drop its malicious files. One of them is the ransom note, which is called _readme.txt and has the following contents:

The main goal of this note is to get you to pay a ransom in Bitcoin to retrieve your encrypted files. Note that these files are AES-encrypted and a unique decryption key is generated that is held by the cybercriminals:

We usually advise against paying the ransom. Your files may not get recovered, as you’re dealing with cybercriminals, and you’ll only enable their further criminal operations against users worldwide.

→vssadmin.exe delete shadows /all /Quiet
