Brace yourselves, all Microsoft Windows users. Companies and governments are worried for the possible second wave of cyber attacks that could strike the world on Monday. On Sunday, Matthieu Suiche of Comae Technologies confirmed it by saying "We are in the second wave."

WannaCry is a very powerful tool by hackers since it locks up computers, encrypts saved data and charges large Bitcoin payments. The said amount could begin at $300 and can rise up to $600, which happens before the software destroys all the files just hours later. Cyber criminals pointed users in 150 nations, including countries such as US, Russia, India, Brazil and Spain. Along with this are major government agencies and organizations.

Security experts state that the single ransomware attack happened on Friday locked up some computers around the world and could cause more trouble on Monday. These affected computers include organizations such as FedEx, the UK hospital, and Germany's train systems may be hacked again as the work week begins. On top of that, copied versions of the malicious software have now started to spread not just on the mentioned stations, but across the globe.

As reported by TechCrunch, security officers and experts are already spreading the news and warning that a new version of WannaCry has developed over the weekend. In fact, earlier today, the National Cyber Security Center of the UK issued a new warning about the chance of another attack. According to the released statement, the detected and "existing infections from the malware can spread within networks."

This outbreak began last Friday and it is already believed to be the biggest and most influential online extortion scheme ever recorded in the history. In order to prevent this, companies and organizations need to update their Microsoft operating systems as fast as possible. According to Mashable, this technique will ensure networks of affected computers that are not still vulnerable to more powerful variants of WannaCry ransomware.
