  What is blockchain technology? A blockchain originally block chain is a continuously growing list of records, called blocks , which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. A blockchain can serve as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". The first work on a cryptographically secured chain of blocks was described in 1991 by Stuart Haber and W. Scott Stornetta.           It can also be defined as " A database or a ledger that maintains a continuously growing list of data records or transactions" . "So, it's a spreadsheet, like Excel?" Many of us may be thinking of that.     In a way yes , but it has qualities that make it better than tradit...

The WannaCry ransomware attack is an ongoing worldwide cyberattack by the WannaCry ransomware cryptoworm, which targets computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. The attack started on Friday, 12 May 2017,and has been described as unprecedented in scale, infecting more than 230,000 computers in over 150 countries. Parts of Britain's National Health Service (NHS), Spain's Telefónica, FedEx and Deutsche Bahn were hit, along with many other countries and companies worldwide. WannaCry spreads across local networks and the Internet to systems that have not been updated with recent security updates, to directly infect any exposed systems. To do so it uses the EternalBlue exploit developed by the U.S. National Security Agency (NSA), which was released by The Shadow Brokers two months before. A "critical" patch had been issued by Microsoft on 14 March 2017 to rem...
