What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A C++ tool that recovers the RSA private key prime numbers generated by the WannaCry ransomware from the wcry.exe process memory. It exploits the fact that Windows XP-era CryptoAPI does not erase key material from memory after release.
Use cases
- recover wannacry decryption key from infected windows xp machine
- decrypt files encrypted by wannacry without paying ransom
- extract rsa prime numbers from ransomware process memory
- check if wannakey technique can work on a running windows os
- analyze wannacry key generation for security research
When to choose
- you have an un-rebooted Windows XP/7 x86 machine infected with WannaCry
- you need to recover WannaCry-encrypted files without paying the ransom
- you are researching ransomware memory artifacts
When to avoid
- the infected machine has been rebooted since encryption
- the system is Windows 10 or newer where memory is cleaned up
- you need a general-purpose ransomware decryption tool
