Turkish security researcher named Utku Sen has posted a fully functional Ransomware code on open source code sharing website GitHub.
The Ransomware dubbed Hidden Tear, uses AES Encryption to lock down files before displaying a ransom message warning to get users to pay up.
The currently undetectable version of ransomware can be modified and implemented accordingly, as it contains every feature a cybercriminal can expect from modern malware.
Sen describes his Ransomware as “a ransomware-like file crypter sample which can be modified for specific purposes.” This means even script kiddies can now develop their own Ransomware to threaten people.

The “Hidden Tear” Ransomware package consists of four files namely:
