A Brazilian developer named Lenon Leite has released proof-of-concept code for a ransomware family coded in PHP that will allow an attacker to encrypt the contents of web servers.

A PHP ransomware project open-sourced on GitHub is still spawning active threats, more than a year after it was released in early 2016.

Open-source code sits at the core of critical internet services and accounts for most of the codebase in modern applications.
