2026 Software Supply Chain Security Report

The 4th annual report from ReversingLabs offers an assessment of the 2025 software supply chain threat landscape including: threats on open-source platforms (malware up 73%), attacks that target developer tooling, and efforts to infiltrate AI development pipelines as the use of AI ramps up risk. 

Key findings of the report include:

• Open-source threats: Why it was the "year from hell" for some popular open-source repos - but better for others
• Toolchain attacks: How threats now target development infrastructure
• AI & vibe coding: How innovative but unsafe processes are opening new lines of attack
• A broken trust model: Requiring a shift in mindset, from implicit trust to continuous validation

The 2026 Software Supply Chain Security Report serves as both a warning — and a guide — for AppSec and product security teams. It's a must-read for CISOs looking to better manage software supply chain risk.
