People around the world were baffled by last week’s WannaCry cyber-attack that hit organizations in more than 100 countries within the span of 48 hours. WannaCry or WanaCrypt0r 2.0 has caused the biggest cyber-attack ever recorded in history.
This massive cyber-attack reminds us the importance of security basics. People those who applied the critical Microsoft Windows patches released in March were protected against this WannaCry attack.
Another basic protection from these kinds of cyber-attacks is having current, offline backups of all the data. This would leave the attackers high and dry.

Way to Unlock Your Files from WannaCry infected Computer
A team of French researchers have found a solution to save files encrypted by WannaCry Ransomware, before it starts to lock up the victim’s computers. WannaCry threatens to lock out victims who have not paid the ransom within a week of infection.
Security researchers across the globe have developed a workaround to unlock the encryption key for WannaCry infected files. They also cautioned that their new solution only works in certain conditions, like if the computer hadn’t been rebooted since becoming infested and if victims applied this fix before WannaCry locks their files permanently.
This new tool which is named as ‘wanakiwi’ is found to recover data in some circumstances according to the tests conducted by European Cybercrime Centre. Wanakiwi tool was quickly tested and shown to work on Windows 7 and older Windows versions like Windows XP and Windows 2003. It should work with any Windows operating system from Windows XP to Windows 7, according to experts.
The Only Workable Solution
Suiche, an independent cyber-security expert has provided advice to ensure the WannaCry fix worked across all versions of Windows OS. It involves extracting the WannaCry encryption keys using prime numbers rather than attempting to break the endless string of digits behind its full encryption key. This is the only feasible solution to help you recover files if you have been infected by WannaCry Ransomware and have no back-ups.
According to an intelligence firm Kryptos Logic, nearly half of all internet addresses corrupted by WannaCry ransomware were located in China and Russia, with 30% and 20% percent infections respectively. The US accounts for 7% of infections while Britain, Germany and France each represents 2% of worldwide WannaCry attacks.
There were only 309 transactions worth $94,000 have been paid into WannaCry hackers accounts as of Friday May 19, 7 days after the WannaCry manifestation. That's less than one in every 1000 of the estimated WannaCry victims.
