Ransomware goes open source
Turkish security bod Utku Sen has published what seems to be the first open source ransomware that anyone can download and spread. The 'Hidden Tear' ransomware, available at GitHub, is a working version of the malware the world has come to hate. It uses AES encryption to lock down files and could display a scare warning or ransom message to get users to pay.
Sen says the malware will bypass detection by all familiar anti-virus platforms. “While this may be helpful for some, there are significant risks. Hidden Tear may be used only for educational purposes. Do not use it as a ransomware,” says Sen.
Sen's Hidden Tear video demonstration shows how the ransomware can encrypt and decrypt files leaving a text document note on the victim's desktop. Various files can be encrypted including word processor documents, spreadsheets and Powerpoint.
