Security researchers have released a tool called Wanakiwi to fix WannaCry Ransomware infected systems for free. Currently, it only works on Windows XP to Windows 7, and only on computers that have not been rebooted since the infection.
The Wanakiwi(WannaKiwi) tool comes from security researcher Benjamin Delpy. This new little tool is based on Adrien Guinet’s wannakey. The fix searches a computer’s memory for encryption prime numbers and then uses those to generate unlock keys for the encrypted files. Restarting the computer could erase these prime numbers.
WannaCry infected 300,000 computers in more than 150 countries on May 12th. The ransomware demands $300 to restore the infected device’s files. WannaCry infects computers outdated Windows versions. Recently, Microsoft also released an update kb4012598 for Windows XP, Windows Server 2003 and Windows 8 to fix this issue.
Note: – The fix only works on Windows XP, Windows Server 2003, Windows 8, Windows 7, and only on computers that have not been rebooted since the infection.
