4th Annual
2026 Software Supply Chain Security Report
How Sophisticated Malware, AI, and Broken Trust are Reshaping Software Security
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.
