Why Network Connectivity Gives Attackers an Edge—Even Without Exploits

Summary

The author argues that broad network reachability, legacy systems, and IT/OT connections give attackers opportunities beyond vulnerability exploits. Citing Google’s 2026 M-Trends report, the article says exploits accounted for 32% of observed initial access vectors in

Key points

• The author argues that widespread IP connectivity can leave systems reachable and make it difficult to limit which computers communicate.
• Google’s 2026 M-Trends report says exploited vulnerabilities accounted for 32% of observed initial access vectors in 2025; the author notes that the remaining 68% did not rely on technical vulnerability exploitation.
• The article says legacy systems can hinder zero-trust approaches that apply identity and authorization to network transactions.
• The author points to accidental connections between IT and operational technology networks as a security risk.
