gadgets prisoners, harm records and so much more.

   keyloggers, Trojans and mobile spyware are forms of spyware.
4. DDoS (Distributed Denial of Service): It is one of the most common types of cyberattacks. DDoS takes place when hackers bombard an organization’s servers with a huge volume of concurrent information demands, subsequently making the servers incapable to
   handle any genuine demands. A DDoS attack endeavors to devour the target’s resources so that it cannot provide normal service. DDoS attacks are designed to take an online resource offline by flooding it with so much activity that it crashes or starts lagging.
   Cybercriminals might carry out DDoS attacks because they want to gain access to information stored on a machine or website or to disrupt the activities of the person or organization responsible for running the targeted resource. In the event that you’re capable
   for overseeing websites or machines that store vital information, attempt utilizing
   administrations like Elastic Compute Cloud (EC2) and Amazon Web Services (AWS) to
   protect your resources against DDoS attacks.
