Police disrupt KillSec ransomware, arrest suspected teenage leader

KillSec, a ransomware-as-a-service operation blamed for roughly 1,000 attacks (about half successful), had its alleged 16-year-old leader arrested in Spain during a multinational operation that also seized the group's leak site and servers; investigators identified multiple suspects and linked the group to exploitation of cloud storage vulnerabilities and extortion of victims across healthcare, government, and financial sectors.
