Notepad++ Hacked for MONTHS?! Supply Chain Attack + Double-Lock Security Fix Explained
Notepad++’s update system was secretly hijacked for months in a targeted supply-chain attack attributed to a Chinese state-linked threat actor. 😳

In this video, we break down:

• How the attackers compromised the update infrastructure
• Why the WinGUp updater was vulnerable
• How the malicious redirection worked
• What systems were targeted
• The new “Double-Lock” security mechanism introduced in Notepad++ 8.9.2
• Lessons for secure software update architecture (DevSecOps + NIST alignment)

This case highlights the growing risk of software supply-chain attacks and why cryptographic verification and update validation are critical in modern software development.

If you're in cybersecurity, DevSecOps, RMF, or GRC — this is a real-world example you should understand.

👉 Upgrade to the latest version of Notepad++ immediately.
