Cyber criminals favouring stealthier attacks like Cryptojacking to make free money

Cyber criminals are switching away from ransomware to stealthier attacks as the main sources of generating revenue, according to analysis by British artificial intelligence (AI)-based cyber security firm Darktrace. Cryptojacking is the unauthorized use of someone else’s computer to mine cryptocurrency. Cryptocurrency is a form of digital currency that can be used in exchange for goods, services, and even real money. Users can “mine” it on their computer by using special programs to solve complex, encrypted math equations in order to gain a piece of the currency.
