Will CL0P ransomware conduct a new mass exploitation campaign using a zero-day vulnerability in 2026?

CL0P's 2023 MOVEit and 2024 Cleo zero-day mass exploitation campaigns demonstrated a repeatable playbook: acquire or discover a zero-day in a widely-used file transfer or enterprise software product, exploit it globally, and extort hundreds of victims simultaneously. This market forecasts whether CL0P will execute this strategy again in 2026.

Resolution Criteria

Resolves YES if: CL0P (or a credibly CL0P-affiliated group) publicly claims victims from a new mass exploitation event leveraging a previously unknown or same-day vulnerability before 2026-09-01. The event must involve 10+ distinct victim organizations.
