Ransomware is a type of malicious software which infects the victim's computer, encrypting all their data. The malware then presents the user with a message to encrypt the files with an unlock code, and demands payment for giving them back.
About PencilCry Ransomware
PencilCry is a ransomware-type program. It encrypts data (renders files inaccessible) and demands victims pay a ransom - to decrypt it. Compromised files are appended with a ".pencilcry" extension. For example, a file initially titled "1.jpg" would appear as "1.jpg.pencilcry", "2.jpg" as "2.jpg.pencilcry", and so on. After the encryption process is complete, ransom notes are created/displayed on a new desktop wallpaper and a pop-up window. The latter is both in English and Portuguese.
The ransom note in the pop-up informs victims that they have to pay to decrypt their data. Unlike other ransom notes, the Pop-up is somewhat demanding. Victims are not given a deadline or time frame of how long they have before losing access to their data, leaving them without any understanding of when it will actually happen. The cryptocurrency being offered gives victims a sense of urgency and makes it difficult for them to deny the guilt of what has happened. A deadline is set - if 120 hours have passed by with no payment made, all decryption ceases.
