Ransomware-stricken organizations grapple with multilevel extortion schemes that are advancing at an alarming rate. What exactly happens in these campaigns? We scrutinize three active ransomware families associated with these schemes to find out.

These tools were intended for use in security research and other authorized purposes. However, cybercriminals have found a way to exploit them for ransomware campaigns. What are some of these tools and how exactly are they weaponized?
