The owners of Windows XP computers infected with the ransomware 'WannaCry' virus could be able to decrypt the data without the need to pay the $ 300 redemption asked by the cyber criminals, thanks to a tool discovered by a French researcher.According to an article published on the website thehackernews, Adrien Guinet, a cyber Security researcher for the French start-up Quarkslab, discovered a way to recover the secret encryption keys which were used by 'WannaCry'. This method works on Windows 7, Windows XP, Windows Server 2003 and 2008 and Windows Vista. Description tool for the 'WannaCry' malwareThe "WannaCry" encryption method works by generating some keys on the computer of the victim based on prime numbers — a public key, and a private key. These keys are used encrypt and decrypt the files from the system. In order to prevent the access of the victims to the private key, so they won't be able to decrypt the blocked files, "WannaCry" deletes the key from the system, leaving the victims no way to recover their files except to pay the redemption to the hacker.But here is the secret — Guinet says "WannaCry "doesn't delete the prime numbers from the memory of the computer before releasing the associated memory. Based on this discovery, he released a decryption tool for the cyber attack called "WannaKey." This tool simply tries to recover from the memory the 2 prime numbers used to generate the encryption keys. The decryption method has some limitationsHowever, the method has some limitations. It can work only if the infected computer was not restarted after it was infected and if the associated memory was not deleted by another process.Guinet warns that the computer should not be restarted after being affected by the malware so this method could work.
