Research Report: 2026 State of the Underground

Stay ahead of underground threats.

The threat landscape isn't quieting down. It's reorganizing. Some indicators declined in 2025, but a lower number is not a safer number. Ransomware groups attacks increased 19%, compromised credentials reached 2.8 billion unique sets, and AI is beginning to compress the time between vulnerability disclosure and active exploitation. The 2026 Bitsight State of the Underground draws on Bitsight Threat Intelligence (TI) to map where underground activity is shifting, who is driving it, and what that means for your organization.

Highlights include:

  • Ransomware volume and payment dynamics, and what declining payments signal about attacker strategy.
  • Why a 41% decline in observed breaches demands more scrutiny, not less.
  • How geopolitical tensions are shaping hacktivism, APT activity, and critical infrastructure targeting.
  • The role of frontier AI in shrinking the defender window between disclosure and exploit.

"The most important question for defenders is no longer just whether a vulnerability is severe — it is whether it is relevant to their environment, their sector, and their vendor ecosystem."
