PARIS (Reuters) – French researchers said on Friday they had found a way for technicians to rescue Windows files encoded by the WannaCry ransom program in a race set by software that hit hundreds of thousands of devices a week ago.

Wana Krai, which began sweeping the world on Friday and infected more than 300,000 computers in about 150 countries, threatened to erase data from victims who did not pay ransoms ranging from $ 300 to $ 600 within a week of injury.

A team of security researchers around the world said they had collaborated on developing a solution to unlock the encryption key for the files in the global attack confirmed by many independent security researchers.

The researchers warned that their solution works only under certain circumstances, including: If the computer has not been restarted since it was infected with malicious software, and the victim must rush to implement the reform before Wana Krai implements its threat to lock its files permanently.

The European cybercrime center has tested the new team tool and confirmed the success of the solution in “recovering data in some circumstances,” Europol said on Twitter.

The researchers launched their free software that will help decrypt infected devices without having to pay the ransom name “WannaKiwi”.

Wanakwei has been tested quickly and has shown its effectiveness on Windows 7 and earlier versions such as Windows XP and Windows Server 2003, one researcher said. The tool, which was hastily developed, may also work on Windows Server 2008 and Windows Vista, Workable on all personal computers affected by malicious software.

So far, financial banks, energy companies and some government intelligence agencies from many European countries and India have been in touch with them on reform, the team said.

As of Wednesday, half of the Internet addresses destroyed globally by Wana Krai were in China and Russia, with 30% in the first and 20% in the other, according to data provided by Cryptos Logic for threat analysis.

By contrast, the United States accounts for just 7 percent of Wana Krai’s injuries, and for Britain, France and Germany each represents only about 2 percent of attacks worldwide, according to Cryptos Logic.
