The ransomware used an exploit known as EternalBlue, which was developed by the NSA after discovering a vulnerability in older Windows software. By the time the attackers released a version of WannaCry with no killswitch, a French researcher, Adrien Guinet, found a way to retrieve the RSA key from the malware files, halting the effectiveness of the attacks. The next step was unusual — the dropper would attempt to connect to an unregistered domain made of a seemingly random string of numbers and letters, halting the attack if a successful connection was made, and continuing the attack if no connection was established. To do this, they split the Bitcoins into three “crypto wallets” to move into Monero, a cryptocurrency which is difficult to appropriate through judicial means.
