Abstract: In the present day, human beings are living in a world which is networked together, ranging from online banking to connected physical infrastructures. The network security that was once optional has now become an exigency. Cyber-attacks have now emerged as one of the prime concerns globally. A cyber-attack is an intentional exploitation of networks, businesses and computer systems. Cyber-attackers make use of their malicious code and other software components to alter or steal information, logic or program data of financial organizations, technology-based companies or individuals leading to cybercrimes such as identity and information theft. Cyber-attacks are ubiquitous in the sense that they could be launched by anyone, at any place and at any time. Cyber breaches are spreading like wild fire globally. Existing security systems can only identify the attacks that are known. This paper aims to expose various cyber-attacks and their present-day impact. This paper also presents some mitigation techniques to stay safe against the cyber-attacks.
