            On Tuesday many security researchers have reported a new wave of potentially destructive ransomware. This ransomware was known as Bad Rabbit. This malicious attack spread quickly across computer systems in Eastern Europe, including targets in Russian and Ukraine and has been detected in the United States.              This attack was barely showing its properties and its damage pattern was similar to the PETYA/NOT PETYA wiper attack that spread earlier this year.              According to the report generated by the Kaspersky.                Bad Rabbit is previously unknown ransomware family.                The ransomware dropper was distributed with the help of drive-by attacks. This happens when the target is visiting a legitimate website, a malware dropper is being downloaded from the threat actors infrastructure.                 The most important thing was that there was no exploits were used.                 As no exploits were used so the victim would have to

  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 traditional databases. Here a
