The group's ability to operate at scale highlights how low the barrier to entry has become for cybercriminal activity, even for minor perpetrators. The successful 'Operation KillSwitch' seizure of 110TB of stolen data underscores the critical importance of organizations reporting breaches promptly to law enforcement to enable coordinated takedowns.
