Humans Remain the Weakest Link – Why Social Engineering Dominates Cyber Threats in 2025
🚨 Humans Are Still the #1 Cybersecurity Risk
📊 Over 80% of organizations now rank social engineering as their greatest threat.
💡 Here’s the twist: it is not just about phishing emails anymore. Attackers are using deepfakes, urgent voice calls, and even video manipulation to outsmart people in ways firewalls cannot stop.
😱 The shock is not in the tools they use – it is in how easily human behavior is exploited. One click, one reply, one rushed decision can unlock the doors no hacker could force open.
🔍 The data tells us most training programs are outdated. Annual awareness sessions fail because attackers test every single day. The result – mid-market firms are losing millions while attackers refine their playbook.
🔥 What works instead? Recurring simulations that mirror real-world social engineering attacks, combined with dashboards that show CISOs and boards exactly where their human vulnerabilities are hiding.
👥 In 2025, the true security perimeter is people – and it is under constant siege.

AI-Powered Attacks Are Disrupting Manufacturing – Here’s How to Stop Them
⚠️ AI Attacks Are Targeting Manufacturing Now
AI-driven cyberattacks are rapidly disrupting manufacturing operations.
Attackers exploit vulnerabilities across robotics, IoT, ERP, and supply chain systems, causing downtime and financial losses.
Traditional defenses are no longer enough against these adaptive, fast-moving threats.
AUMINT.io helps manufacturers stay ahead with simulations, real-time monitoring, and actionable insights to identify vulnerabilities before attackers exploit them.
Preparation is the difference between continuity and costly disruption.
