Ransomware and Intrusion Trends Report 2026
A sourced view of ransomware persistence, intrusion acceleration, social engineering growth, and why identity plus remediation discipline now matter as much as perimeter technology.
Ransomware remains operational, not historical
Verizon's 2025 DBIR shows ransomware still present in 44% of breaches, with SMB exposure especially severe. It remains a board-level continuity issue, not a niche technical risk.
Initial access keeps shifting toward speed and deception
Official reporting points to higher vishing activity, strong adversary acceleration, and continued abuse of exposed systems and valid credentials.
Containment depends on identity, patching, and remediation discipline
The most practical defensive posture is still operational: reduce exploitable exposure, tighten identity boundaries, validate backups, and make remediation ownership explicit.

What leadership teams should do now
Reduce exploitable exposure
Internet-facing weaknesses still create outsized risk. Patch cadence, external attack surface review, and remote access hardening should be continuously managed.
Harden identity and admin paths
Credential abuse and valid account access are central to modern intrusion. Privileged access review and identity containment are operational priorities.
Pre-plan remediation ownership
Assessments matter, but response quality is defined by who fixes what, how fast, and how closure is validated after the technical work is done.
