Simple C Ransomware I built to learn more about C and Ransomwares.

Source code for the ransomware is in main.c, Testing contains codes for parts of the ransomware, DummyFiles contains files used for testing the encryption.

Since it is using xor encryption currently, run it once to encrypt run it again to decrypt your files.

Compile the program and run it with the path you want it to start encrypting as the argument.

$./main /home/

• Use stronger encryption algorithm
• Add a challenge for victims complete to retrieve their files
• Add a C&C Server
