Frenchmen claim cure for WannaCry-infected computers

WannaCry, which started to sweep round the globe last Friday and has infected more than 300,000 computers in 150 nations, threatens to lock out victims who have not paid a sum of $300 to $600 within one week of infection.

The researchers have posted the tool on their blog for free download ad have cautioned that it only works if the infected system has not been rebooted since the attack and the files have not been locked permanently by the ransomware.

However, using Guinet's findings, Benjamin Delpy, another security researcher, has developed a tool called WanaKiwi.

Have a computer infected by WannaCry ransomware?

The researchers said the tools are not flawless and only work if the infected computers have not been rebooted after being hit by the programme. And it only works on Windows XP.

In his research summary, Mr Guinet - who works for the Paris-based firm Quarkslab - said his software had only been tested to work under Windows XP. Wanakiwi provides additional improvements over Wannakey, including a point-and-click interface and the ability to generate the full decryption key without the need for other tools.

"This is not a flawless solution", Suiche said. He said the software helps recover the prime numbers of the RSA private key that are used by WannaCry. Matt Suiche of Comae Technologies has offered a few examples of how to manually decrypt your WannaCry-affected files using WanaKiwi.

As of Wednesday, half of all internet addresses corrupted globally by WannaCry were located in China and Russian Federation, with 30 and 20 percent of infections, respectively, according to data supplied by threat intelligence firm Kryptos Logic.

One week after it first hit, researchers are getting a better handle on how the WannaCry ransomware spread so quickly - and judging from the early figures, the story seems to be nearly entirely about Windows 7.

You might expect Windows XP to be next in the list, but no. 2008 R2 Server clients claim that spot with just over 1 percent.

This may reflect a variety of factors, security experts say, including scepticism that attackers will honour their promises or the possibility that organisations have back-up storage plans allowing them to recover their data without paying ransom.
