In this digital age, Cybercrime is any crime committed using the computer or any connected digital devices.

Cybercrime started in the 1970s with the hacking of computerized phones to make long distance calls without paying.

Currently, individuals, governments and organizations are losing billions of dollars annually to cybercrime. The FBI which is one of the foremost fighters of cybercrime is currently investigating more than 1000 cases of cybercrimes committed in the US or against US citizens.

  1. Distributed Denial of Service (DDoS)

Distributed Denial of Service (DDoS) attacks are designed to overwhelm a target system, network, or website with an enormous volume of traffic, rendering it inaccessible to legitimate users.

Cybercriminals achieve this by harnessing a network of compromised devices, forming a botnet, and orchestrating a coordinated assault. DDoS attacks can paralyze businesses, disrupt online services, and inflict substantial financial losses.

Implementing robust network security measures, employing traffic monitoring solutions, and utilizing content delivery networks (CDNs) can help mitigate the impact of DDoS attacks.

In addition, DDoS targets organizations like Banks and other organizations like Gaming industries, and other major websites and services.

Also, DDoS works by hijacking smaller computer networks and servers, IoTs, and other devices to direct traffic to the target. The target is overwhelmed by the traffic and eventually brought down.
