🚨 How a Trusted Tool Became a Stealthy Threat Vector
Supply-chain attacks aren’t just theoretical — they’re happening to software most developers trust every day.
Our latest Hack & Fix investigation breaks down the Notepad++ supply-chain attack that compromised the update process for months, without modifying the core application itself. We go deep into how attackers hijacked update infrastructure, delivered malicious payloads, and what defenders can do to detect and respond.
🔍 What you’ll learn:
• How the compromise worked — step by step
• Confirmed Indicators of Compromise (IoCs) — domains, IPs, file hashes
• C2 infrastructure and behavioral detection patterns
• Practical threat-hunting and mitigation guidance
