Popn Ransomware is a harmful virus that encrypts files on a victim's computer and demands payment in exchange for the decryption key. It belongs to the STOP/Djvu ransomware family and is usually distributed through malicious websites, spam emails, fake software cracks, or by exploiting vulnerabilities in the operating system and installed programs. Once the ransomware is downloaded and executed, it initiates the encryption process on the victim's system, irrespective of the distribution method. Cybercriminals employ a wide range of file types, including PDFs, Microsoft Office documents, and more. Popn appends .popn extensions to files and utilizes a file renaming pattern, transforming files such as 1.jpg into 1.jpg.popn, 2.png into 2.png.popn etc. The ransomware generates a ransom note called _readme.txt that instructs the victims to pay a specific amount to receive a decryption key to restore access to their files. Failing to meet the payment deadline might result in the irreversible loss of the compromised data.
