If you’re one of the thousands of victims of WannaCry, the largest ransomware attack in history, there might be a glimmer of hope for you. Security researchers have released a fix to get rid of the ransomware, given you haven’t rebooted your computer yet.
Developed by security researcher Benjamin Delpy, a.k.a. “gentilkiwi,” the fix is called “wanakiwi.” This ingenious tool is based on an older fix of “WannaKey” created by Adrien Guinet, which was designed to fix Windows XP Keys. Benjamin Delpy updated the key and made it work on Windows 7 devices.
How does it work?
The program searches your computer memory for prime numbers, which is the foundation of encryption. Using those prime numbers it then generates unlock keys for the encrypted files. However, if you rebooted since becoming infected, it could erase the prime numbers, thus the fix won’t work.
Europol’s Cyber Crime Centre found it successful in some measure after testing it.

The WannaCry ransomware, which isn’t over yet, was unleashed on 300,000 computers in more than 150 countries last week. Thousands of major institutions around the globe, including United Kingdom’s National Health Service, are the victims of this ransomware. It demanded $300 in Bitcoin from each victim, giving them one week to pay. This fix may not help everyone, but if you’re lucky enough to not restart your computer, hopefully, it will help you.
