A team of French security researchers have come up with a solution that may help users impacted by the WannaCry ransomware. According to reports, a researcher named Adrien Guinet came up with a way to decrypt encrypted files due to a subtle flaw in the WannaCry code and Benjamin Delpy, an employee of the Banque de France, used Guinet's methods to create a free decryption tool which he dubbed "wanakiwi."

The developers released the tool yesterday, as the deadline expires for computers all over the world first infected a week ago. It is expected that the fix would help to recover victim's encrypted files without having to fork over $300 worth of Bitcoin to hackers. 

The cyber security firm Kaspersky Lab earlier yesterday stated that approximately 98% of all machines hit by WannaCry were running an iteration of Windows 7. One drawback is that the fix only works if the computers were not rebooted from the moment of infection. Wanakiwi was quickly tested and shown to work on Windows 7 and older Windows versions XP and 2003.

Within last week more than 300,000 computers in nearly 150 countries were infected with WannaCry. It is believed that the hackers behind WannaCry only managed to bag around $90,000.
