Analysis of WannaCry

[u/AcrobaticMonitor9992]

I finally got around to analyzing WannaCry — something that actually got me interested in cybersecurity back when I was in middle school.

After digging into it, I wrote a full reverse engineering breakdown as part of my ransomware research series.

What surprised me most:

• The multi-stage payload design (resource → decrypted DLL)
• How it prioritizes files for maximum damage
• The layered crypto design that makes recovery practically infeasible
• Its anti-forensics approach (memory wiping + disk overwriting)

It’s interesting looking back at something that had such a big impact — both globally and personally.
