The Ducky Ransomware is a ransomware threat that has been observed in the wild. The Ducky Ransomware can completely lock users out from accessing their own files. The threat achieves this by deploying an encryption routine with a strong cryptographic algorithm on any compromised system. All files encrypted in this manner will have '.ducky' appended to their original names as a new extension. Like all ransomware, Ducky will then proceed to extort its victims for money in exchange for the decryption key and tool that could potentially restore the locked files.
The Ducky Ransomware delivered its ransom note in two different forms. The threat will drop text files named 'RECOVER YOUR FILES.txt' in all folders containing encrypted data. At the same time, a pop-up window will be generated from a file called 'RECOVER YOUR FILES.hta.' The text files tell the victims of the Ducky Ransomware that they will have to establish communication with the hackers. For that purpose two communication channels are provided - an email address at 'firstname.lastname@example.org' and a Telegram account '@duckydecrypt.' The hackers warn that after 48-hours have passed, the price for decryption will be doubled.
The message displayed in the pop-up window is nearly identical. The only significant difference is the inclusion of a warning about anti-malware products potentially corrupting the encrypted files or deleting the Ducky Ransomware threat, which could make decryption impossible.
The ransom note delivered inside the text files states:
'All your files have been encrypted due to a security problem with your PC. Write to us in telegram, we will help you: T.me\duckydecryptWrite to the contacts, we will help you recover several files for persuasion: email@example.com
