Ransomware threats are a very popular type of malware. Such data-locking Trojans would infiltrate your system, lock your data using an encryption algorithm, and then demand a sometimes staggering fee in return for a decryption key, which is supposed to unlock all the affected files.
Propagation and Encryption
One of the newest threats in the world of ransomware is the Cetori Ransomware. When researchers studied the Cetori Ransomware, they found out it belongs to the STOP Ransomware family. However, experts have not been able to reach a consensus regarding the propagation methods employed in the spreading of the Cetori Ransomware. Some state that it is highly like that mass spam email campaigns, alongside fake software updates and pirated copies of legitimate software may be among the infection vectors utilized by the authors of the Cetori Ransomware. As soon as the Cetori Ransomware compromises your computer, it will scan it to locate all the files, which it will encrypt. The Cetori Ransomware will go after all the popular filetypes such as '.mp3,' '.jpeg,' '.png,' '.gif,' '.pdf,' '.txt,' '.ppt,' etc. Then, the Cetori Ransomware will begin the encryption process. After the encryption process is completed, all the affected files' names will be altered. The Cetori Ransomware applies a '.cetori' extension to the file name. For example, a file, which was named 'gray-cat.jpeg' initially, will be renamed to 'gray-cat.jpeg.cetori.'
The Ransom Note
Next, the Cetori Ransomware will drop a ransom note that goes by the name '_readme.txt' and states:
