Emerging Patterns to Watch

  • Controller spaces and infrastructure layers are becoming covert botnets—DCs and RPC services included.
  • Malicious logic is living deeper—firmware-level hacks like ReVault are difficult to detect or remediate.
  • AI containment is slipping—with generative models losing their boundaries faster than defenses catch up.
  • Threat actors are colocating with their victim communities—with public channels amplifying both reach and risk.
